12th Singapore Raptor Watch Report (2019)

Autumn 2019 Migration – 9 Nov 2019

Black Baza, at Puaka Hill, Pulau Ubin, 9 Nov 2019, by Jacky Soh

The 12th Singapore raptor watch was held on Saturday, 9 November 2019 and involved 45 participants. The weather was fine. There were seven raptor watch sites and the numbers counted at each site varied from a high of 175 to a low of 43 birds. A total of 714 raptors were counted, including 562 raptors representing 10 migrant species (two species more compared to last year) and 93 raptors of 6 resident species. A further 59 raptors could not be identified to species level.

Most of the sites were the same ones as previous years, thanks to all the site leaders for their faithful support!  The minor changes were the shifting of the Japanese Gardens site to Jurong Lake Garden, and a slight shift of the Tuas site to Tuas South Avenue 10. We also had an opportunity to add in Tuas South Link, where the records were distinct (based on timing of the birds) from the other Tuas site.

The highest number of raptors recorded was at Jurong Lake Garden (175 birds), followed by Telok Blangah Hill Park (147 birds) and Tuas South Avenue 10 (107 birds). The greatest diversity of migrant raptors was at Telok Blangah Hill Park with seven species, followed by Jurong Lake Garden with six species, and Puaka Hill with five species. The other sites all recorded three migrant species.

The peak hours for migrant raptors were between 11am to 12pm (133 migrant raptors) followed by a higher peak from 3pm to 4pm (194 migrant raptors).

The Oriental Honey Buzzard (OHB) were present at all the sites and claimed the top spot again, with 398 birds counted. The largest number of OHB were at Jurong Lake Garden (155 birds), Tuas South Avenue 10 (86 birds) and Tuas South Link (64 birds). There were 104 Black Bazas across five sites, with Telok Blangah Hill Park recording the most (57 birds).

A total of 34 Japanese Sparrowhawks were recorded across all sites. The 17 Chinese Sparrowhawks were recorded at three sites only, with the bulk at Puaka Hill, Pulau Ubin (14 birds).

Three Western Ospreys were recorded – two at Tuas South Link and one at Puaka Hill. Interestingly, two Greater Spotted Eagles were recorded, one at Jurong Lake Garden from 10am to 11am and one at Telok Blangah Hill Park from 12pm to 1pm – could these have been the same individual flying eastsoutheasterly?

Only one Grey-faced Buzzard and one Peregrine Falcon were recorded – both at Jurong Lake Garden; as well as one Common Buzzard and one Jerdon’s Baza – both at Telok Blangah Hill Park.

Singapore Raptor Report – October 2019

Oriental Honey Buzzard, juvenile, showing its long neck and slim bill, at Henderson Waves, 19 Oct 2019, by Zacc HD

Summary for migrant species:

October 2019 is as remarkable as last year, with 11 migrant species recorded (we usually record around 9 species in October). Henderson Waves continued to be a popular place to watch migrating raptors. A total of 712 migrant raptors were recorded, with another 48 unidentified accipiters, which are likely to be migrants too.

The most numerous were the 425 Oriental Honey Buzzards, followed by 135 Japanese Sparrowhawks, and 130 Chinese Sparrowhawks (quite a jump compared to last October’s 57). Notably no Black Baza was recorded.

Besra, juvenile, note the lightly marked underwing coverts and strong mesial stripe, at Jelutong Tower, 18 Oct 2019, by Francis Yap

A rare Besra was photographed by Francis Yap at Jelutong Tower on the 18th and amazingly, another at Henderson Waves on the 31st, photographed by both Deborah Friets and Looi Ang Soh Hoon, lucky birders indeed. Both the Besras were juveniles. Another rarity was the Common Kestrel, seen and photographed at Tuas South on the 5th.

Booted Eagles are now harder to see as they no longer seem to winter here, occurring only as passage migrants, but Keita Sin got lucky at Henderson Waves on the 30th, photographing one as it flew over. The uncommon Grey-faced Buzzard was only recorded on the 30th – two birds at Henderson Waves in the morning and one at Bukit Timah summit in the afternoon.

Common Kestrel, at Tuas South, on 5 Oct 2019, by Francis Yap

The Eastern Marsh Harrier was recorded on passage at Kranji Dam on the 7th (a juvenile); at Kranji Marshes on the 14th (a female); and on the 28th, one juvenile was first photographed at Seletar at 9:01am and thereafter at Jelutong Tower at 9:28am.

The Common Buzzard was recorded at the Southern Ridges area only – a juvenile dark morph at Kent Ridge on the 11th, two adult pale morphs at Henderson Waves on the 12th, a juvenile pale morph at Henderson Waves on the 20th, and another juvenile pale morph at Kent Ridge on the 24th. (Note: the various subspecies are ‘lumped’ as Buteo buteo in the NSS bird checklist).

Highlights for sedentary species:

There were two records for the locally scarce Crested Serpent Eagle, one at Henderson Waves on the 14th and another at Neo Tiew Harvest Link on the 18th; five records for the  Grey-headed Fish Eagle, one each at Pandan, Botanic Gardens, Coney Island and two at Henderson Waves; five records for the Crested Goshawk, one each at Satay by the Bay, Pasir Ris Park, Woodlands Street 81, and two at the Henderson Wave – Kent Ridge area. were observed mating at West Coast Park. Then on 23 Oct, 2 chicks of the were seen on a nest at Woodlands. These  are good signs for our resident raptors.

On 5th Oct, a Peregrine Falcon of the resident ernesti subspecies recorded at Henderson Waves; and on 30th Oct, a torquatus Oriental Honey Buzzard was photographed at Bukit Timah summit by Alan OwYong. The other resident raptors recorded included four Black-winged Kites at Tuas and two at Kranji Marshes; eleven Changeable Hawk-Eagles; and the common Brahminy Kite and White-bellied Sea Eagle. To streamline the report, only notable records, such as breeding-related or interesting behaviour, will be reported for the last two species.

Many thanks to everyone who had reported their sightings in one way or another, and especially to Zacc HD, Deborah Friets, Adrian Silas Tay and Francis Yap for the use of their photos.

Singapore Bird Report – October 2019

The Black-naped Monarch at the Botanic Gardens

Black-naped Monarch, Botanic Gardens, 21 Oct 2019, a clear photo by Kelvin Ng Cheng Kwan. Note the unnatural damage to the tail and tertials (broken & frayed tips); the feathers on the mantle also look unnaturally messy

The biggest find of the month was the extremely rare Black-naped Monarch, Hypothymis azurea, which also turned out to be the biggest disappointment, as it is in all likelihood an escapee. The monarch was first spotted at the Botanic Gardens on 18 October 2019 by visiting birder, Jan Lile, from Queensland, Australia. Her ebird record was picked up by Andrew Paul Bailey, who alerted birders on FB group ‘Bird Sightings’. Ramesh T. followed the lead the following day and found the bird, thereby alerting others to its continued presence. The bird remained at the Botanic Gardens until 24 October 2019, allowing many birders to see and photograph this great rarity, which unfortunately, turned out to be of captive origin.

A review of more than 60 photographs of the monarch showed evidence of unnatural feather damage, particularly to the tertials which were not only frayed, but also broken (tip of top left tertial); there were also unnatural wear to the tips of the primaries and especially to the tail feathers – indeed, the ends of three tail feathers were broken (see pic below); the mantle feathers were unnaturally messy – probably either through being handled or from flying against a cage; overall, the bird had a somewhat untidy appearance, hinting at its captive origin.

Black-naped Monarch, Botanic Gardens, 21 Oct 2019, a photo from an unusual but useful angle, by Kelvin Ng Cheng Kwan. Note the unnatural broken tips to T2 & T4 (left side of tail), and broken T6 (right side of tail)

The Black-Naped Monarch had only been recorded on mainland Singapore once – on 1 January 2004. The species is rare on Pulau Ubin, and there are some records from Pulau Tekong; it is more usually encountered in the lowland rainforests, peat swamps, secondary forests and overgrown plantations in Malaysia (Wells, 2007:168-169).

Central Catchment Nature Reserve (CCNR) and Fringe Parks

Birders visiting the CCNR core reported the influx of migratory birds visiting or passing over the central forests. On 5 October 2019, a White Wagtail Motacilla alba was spotted by Adrian Silas Tay. A full adult male Siberian Blue Robin, Larvivora cyane, was seen at Venus Loop on 13 October 2019 by Felix Wong, while a pair of resident Short-tailed Babbler, Malcocincla malaccensis, were spotted within the same locality on 18 October 2019 by Alan Owyong. On 20 October 2019, a first-of-the-season Ferruginous Flycatcher, Muscicapa ferruginea, was recorded by Luke Teo at Mandai Track 15. Towards the end of the month, a Cinereous Bulbul, Hemixos cinereus, a non-breeding visitor, was spotted on 25 October 2019 from Jelutong Tower by Francis Yap.

A first-of-the-season female Siberian Thrush, Geokichla sibirica, was recorded on 22 October 2019 by Richard White, while another individual was seen at Thomson Nature Park on 25 October 2019 by Lian Yee Ming. On the summit of the Bukit Timah Hill, a Yellow-vented Flowerpecker, Dicaeum chrysorrheum, was seen on 29 October 2019 by Alfred Chia, feeding in a fruiting fig tree. The next day on 30 October 2019, a first-of-the-season Grey-Faced Buzzard, Butastur indicus, was spotted flying over, by Fadzun Adnan.

Besides the Black-Naped Monarch, other birds seen include four Grey-headed Fish-Eagle Haliaeetus ichthyaetus – a juvenile and adult at the Symphony Lake, and two adult birds at the Gallop Extension on 26 October 2019 by Geoff Lim.

Central Singapore

Despite a drastic reduction in area, Bidadari continued to support a number of migratory birds. The globally vulnerable Brown-chested Jungle Flycatcher, Cyornis brunneatus, was spotted on 1 October 2019 by T. Ramesh at the area near the fallen tree at the former side entrance to the area, while a male Siberian Blue Robin, Larvivora cyane, was also seen on the same day by Deborah Friets. On 3 October 2019, a Brown Shrike, Lanius cristatus lucionensis was spotted by Alan Owyong.

On 7 October 2019, an Oriental Dwarf Kingfisher, Ceyx erithaca, was spotted by Gan Lee Hsia, while a first winter Crow-billed Drongo, Dicrurus annectans, was seen on 7 October 2019 by Terence Tan. On 16 October 2019, a male white morph Amur/Blyth’s Paradise Flycatcher, Terpsiphone sp., was spotted by Deborah Friets, while a Dark-Sided Flycatcher, Muscicapa sibirica, was seen on 26 October 2019 in the afternoon after the rain, by “Trustmind Ng”. The next day, on 27 October 2019, a Chinese Sparrowhawk, Accipiter soloensis, was spotted by Low Chong Yang, who visited the former cemetery at 7am.

Other birds reported within Central Singapore included an Oriental Dwarf Kingfisher, Ceyx erithaca, that was found by Peng Ah Huay’s friend, in Ang Mo Kio Central, weak and not flying; a returning Chinese Sparrowhawk, Accipiter soloensis, that was seen on 27 October 2019 by Angela Yeo at Ang Mo Kio Town Garden West; while a Blue-Winged Pitta, Pitta moluccensis, was reported by Kwok Tuck Loong on 31 October 2019 at Geylang East Avenue 1 at about 7am.

Northern Singapore

On 1 October 2019, a single White-shouldered Starling, Sturnia sinensis, was seen along Seletar Club Road, flying from a tree to across the road with other birds, by Pary Sivaraman. On the same day, a mixed flock containing more than 100 Grey Wagtail, Motacilla cinerea, and a Forest Wagtail, Dendronanthus indicus, were reported at a communal roost at Yishun by Khoo Mei Lin.

An Oriental Dwarf Kingfisher, Ceyx erithaca, was reported to have crashed into a home at Recreation Road on 2 October 2019 by Janet Neo, and subsequently released, while a Blue-winged Pitta, Pitta moluccensis, was reported to have crashed into a home in Minton Condominium on 10 October 2019 by Tan Tze Khing and survived.

Not so fortunate was a von Schrenck’s Bittern, Ixobrychus eurhythmus, that was reported dead at the foot of a HDB flat along Compassvale Road on 29 October 2019 by Zhang Licong, while a Black Bittern, Dupetor flavicollis, was reported as having crashed into a home in Serangoon on 31 October 2019 by Charmiane Magnus Kuan, and subsequently released.

Eastern Singapore

The eastern islands of Pulau Ubin and Pulau Tekong had only two reports. We received a report of a first-of-the-season Long-Toed Stint, Calidris subminuta, on 3 October 2019 at Pulau Tekong from Frankie Cheong, while we had a report of more than 50 Swift Tern, Thalasseus bergii, on 4 October 2019 on Pulau Ubin from Tan Ju Lin and Tiak Lee.

The woods along a canal near Changi Business Park was reported to support two visiting Green Imperial Pigeon, Ducula aenea, (1 October 2019, Mike Hooper), a Crow-Billed Drongo, Dicrurus annectans, a first-for-the-season Grey Nightjar, Caprimulgus jotaka, and a Brown-Chested Jungle Flycatcher, Cyornis brunneatus, (28 October 2019, T. Ramesh). Further away at Bedok Camp, more than 300 Oriental Pratincole, Glareola maldivarum, were seen flying south on 27 October 2019 by Oliver Tan, while a Blue-Winged Pitta, Pitta moluccensis, was spotted within Eastwood Estate on 30 October 2019 by Herman Phua. Over at Pasir Ris Park, Josh Spiler made an unusual report of a Lanceolated Warbler, Locustella lanceolata, which was spotted within the mangrove woods of on 12 October 2019.

Southern Singapore

A stray Spot-Billed Pelican Pelicanus philippensis on 3 October 2019 at Marina Barrage by John Marriott, possibly an escapee from our bird park, while a Drongo Cuckoo, Surniculus lugubris, was seen on 21 October 2019 at Gardens-by-the-Bay by Carmen Hui. Reports of the Blue Rock Thrush, Monticola soltarius, at Pinnacle@Duxton continued to filter through on 3 and 6 October 2019 from Tay Kian Guan and Norhafiani Majid, respectively. Further west, a first-of-the-season Common Buzzard, Buteo buteo, was seen on 11 October 2019 by Zacc HD.

The Henderson Waves proved to be a productive site during the migration season, not just for raptors, but also for other migrating birds. On 10 October 2019, ninety-three Red-rumped Swallow, Cecropis daurica, flying over the ridges were counted by Oliver Tan, who also spotted a Crested Serpent Eagle, Spilornis cheela, on 14 Ocotber 2019. A Brown-Backed Needletail, Hirundapus giganteus, was seen speeding over on 19 October 2019 by Zacc HD, as did an Asian House Martin, Delichon dasypus, by Gayathree Arasu. Raptor watchers who persisted their vigil were rewarded by a first-of-the-season Booted Eagle, Hieraaetus pennatus, on 24 October 2019 (Keita Sin), a first-of-the-season Sand Martin, Riparia riparia on 26 October 2019 (Martin Kennewell), four more Asian House Martin, Delichon dasypus on 27 October 2019 (See Toh Yew Wai), and a juvenile Besra, Accipiter virgatus, on 31 October 2019 (Looi Ang Soh Hoon).

Western Singapore

At Sungei Buloh Wetland Reserve, a single Lesser Adjutant, Leptoptilos javanicus, was seen soaring over the park on 1 October 2019 by Tay Kian Guan, while a rare Chinese Egret, Egretta eulophotes, was photographed on 6 October 2019 by Teo Nam Seng. The charismatic Black-capped Kingfisher, Halcyon pileata, appeared on 27 October 2019, a first-of-the-season record reported by Art Toh.

A single Common Moorhen, Gallinula chloropus, was seen preening itself in the evening at Lim Chu Kang Lane 3 by Francis Yap. Over at Kranji Marshes, a first-of-the-season record of an Oriental Reed Warbler, Acrocephalus orientalis was reported on 2 October 2019 by Wing Chong. A few days later on 6 October 2019, another first-of-the-season report of a Lanceolated Warbler, Locustella lanceolate, was made by Tan Yew Chong. On 28 October 2019, Veronica Foo accounted for a first-of-the-season Von Schrenck’s Bittern, Ixobrychus eurhythmus, as well as a Pallas’s Grasshopper Warbler, Locustella certhiola. Along Harvest Link just outside Kranji Marshes, a Peregrine Falcon, Falco peregrinus japonensis, was reported on 12 October 2019 by Looi Ang Soh Hoon, as were 16 Oriental Pratincole, Glareola maldivarum, and two Long-Toed Stint, Calidris subminuta, (Alan Owyong), while 3 Pratincole were spotted the next day (13 October 2019) by Lim Kim Chuah, who also recorded a Little Ringed Plover, Charadrius dubius. On the following day, 14 October 2019, an Eastern Marsh Harrier, Circus spilonotus, was spotted by Tay Kian Guan.

Over at Kranji Dam, White-winged Tern, Chlidonias leucopterus, were seen flocking with Whiskered Tern, Chlidonias hybrida, on 1 October 2019 by Adrian Silas Tay, with eight of the latter flying towards Johor during last light. On 7 October 2019, a first-of-the-season record of an Eastern Marsh Harrier, Circus spilonotus, was reported by Chen Boon Chong, who noticed that it chased a Striated Heron out before flying back to the trees. The harrier later flew out in a south-westerly direction five minutes later.

A few adventurous birders ventured into Tuas and found a Common Kestrel, Falco tinnunculus, on 5 October 2019 (Low Choon How), and a Jambu Fruit Dove, Ptilinopus jambu, on 28 October 2019 (Adrian Silas Tay).

This report is written by Geoff Lim, with records compiled by Alan Owyong and edited by Tan Gim Cheong. We are grateful for the birders and photographers whose postings in various Facebook birding pages, bird forums, individual reports and extracts from eBird make up this report. This compilation is not a complete list of birds recorded for the month and not all the records were verified.

Many thanks to Kelvin Ng Cheng Kwan, Francis Yap, Amin, Norhafiani A. Majid, Herman Phua and Alan Owyong for allowing us to use their photographs.

The 35th Singapore Bird Race (2019)

by Geoff Lim, Morten Strange, Tan Gim Cheong & Lim Kim Chuah. Photos by Francis Chia.

The 35th Singapore Bird Race, which took place from 16-17 November 2019, attracted more than 130 participants who formed 43 teams – a record number. The participants included more than 60 students from Primary and Secondary Schools. The number of teams for the various categories were as follows: eight for Primary School, nine for Secondary School, five for Marathon, ten for Sprint, and 11 for Photographers.

The first ever race took place in 1984, and is today, one of the longest running citizen science events in South-east Asia. A key objective of the race is to promote the appreciation of birds and biodiversity to the public. It also brings people from different walks of life together, and get them to go outdoors to look at birds and nature.

Participants of the School category – 35th Singapore Bird Race, @ MBC.

The Marathoners kicked off their gruelling 20-hour race at 4:30pm on 16 November 2019, while the race for the Sprint and Photographer categories was flagged off at 7:30am on 17 November 2019, followed by the School category at 8am, at Mapletree Business City.

Highlights for the School category

The school teams were confined to race in parks close to the vicinity of Mapletree Business City. The parks included HortPark, West Coast Park, Kent Ridge Park and Mount Faber Park. And unlike previous years, some calls were allowed this year so as to encourage more birders to take an interest in bird calls. The winner of the primary school category, Yumin Champs One recorded a respectable score of 20 species while the winner of the secondary school category, Goated-Spotters from Dunman Secondary School topped the category with a score of 35 species. The students had plenty of fun along the way and for many of them, this was the first time they were visiting these parks. Also, for most of them, it was also their first time seeing interesting species such as Oriental Pied Hornbill, the globally endangered Straw-headed Bulbul (pictured on the event T-shirt and allowed to be recorded by call), our delightful ‘little red dot’ unofficial national bird the Crimson Sunbird and many raptors, including the migratory Japanese Sparrowhawk.

Highlights for the Marathon, Sprint and Photographer categories

The teams turned out a great set of results, including one team that exceeded 100 species of birds in a relatively short 20-hour period. There were also many close fights with placings determined by teams having just one more species than the next team. Indeed, the champions for the Sprint category edged pass the 1st runner-ups by just one species! The 1st runner-ups in the Marathon category also edged pass the 2nd runner-ups by one species. And the two teams in the Marathon category who tied for 4th place also lost to the 2nd runner-ups by just one species. The defending champions of the Photographer category were so well ahead of the pack that they were pretty close to the top three placings for the Sprint category, amazing.

Best bird of the race is arguably a rare Grey-headed Lapwing at Turut Track, spotted and photographed by a few lucky teams. The critically endangered Straw-headed Bulbul was recorded at the Kranji Marshes, Neo Tiew Woods, Gillman Barracks area, and Sungei Buloh Wetland Reserve (SBWR). Dairy Farm Nature Park turned out to be a hotspot for uncommon birds such as the Jambu Fruit Dove, Greater Green Leafbird, Cinerous Bulbul, Blue-rumped Parrot, Red-crowned Barbet, Eye-browed Thrush and Siberian Thrush. Another rare bird recorded during the race was the Lesser Adjutant at SBWR.

Singapore Raptor Report Early Autumn Migration, July-September 2019

A Western Osprey with a big catch, Sungei Buloh Wetland Reserve, 11 July 2019, by Sim Chip Chye

Summary:

The early migrants included all the five expected species, namely the Western Osprey, Oriental Honey Buzzard, Chinese Sparrowhawk, Japanese Sparrowhawk, and Peregrine Falcon, during the July to September period.

A total of 46 Oriental Honey Buzzards were recorded. There were at least seven immature orientalis in July, four in August, and three in September – these are individuals hatched last year, over-summering here this year and are expected to migrate to the north only next spring. At least two torquatus were recorded – one photographed at Springleaf on 20 July by Alex Fok, and a tweeddale morph photographed at Upper Seletar Reservoir on 10 September by Deborah Friets.

The first Japanese Sparrowhawk was recorded on 13 September at Jalan Bahar, and on 26 September, Adrian Silas Tay recorded 28 at The Pinnacles Duxton, including a flock of 12. Aother eight were recorded at Henderson Waves on 28 September. All in, 47 early arriving Japanese Sparrowhawks were recorded.

The first three Chinese Sparrowhawks were recorded on 22 September at Tuas. They were followed by two on 27 September at Jelutong Tower, 3 on 28 September at Henderson Waves, and 8 on 29 September at Tuas.

Four Western Ospreys were recorded, with one at Sungei Buloh Wetland Reserve (SBWR) on 11 July having caught a big fish. The others were singles at the Botanic Gardens on 7 July, Seletar Dam on 14 September, and Marina Bay on 26 September.

Four Peregrine Falcons were recorded – an adult ernesti on 6 Jul at Telok Blangah; a juvenile of indeterminate race on 27 July at Pulau Ubin; a far individual at Marina Bay on 3 August, possibly an ernesti; and another at Kranji Marsh on 29 Sep.

For the resident raptors, seven diurnal species were recorded. Apart from the usual ones, there were records of the rare Crested Serpent Eagle at Pulau Ubin on 2 July & 8 September, and at Malcolm Road on 6 July & 6 September. Notably for nocturnal raptors, a recently fledged juvenile Spotted Wood Owl at Pasir Ris Park fell to the ground on 11 July, but managed to climb back up the tree to reunite with its parents.

Many thanks to everyone for their records and to Sim Chip Chye and Ros Qian for the use of their photos.

 

Singapore Bird Report – September 2019

by Geoff Lim & Tan Gim Cheong (ed.)

September 2019 marked the appearance of rarities such as the Glossy Ibis, Black-naped Monarch, Blue Rock Thrush, and Japanese Paradise Flycatcher; as well as the first arrivals of many migrants.

Glossy Ibis Sighting

The Glossy Ibis, Plegadis falcinellus, is a widely distributed species that is found in Europe, Africa, Asia, Australia, Central and North America. However, it is a very rare vagrant in Singapore. The sighting on 28 and 29 September 2019 by Raghav and Goh Cheng Teng, respectively, was our fifth sighting to date. Prior sightings were at Lorong Halus in 12-16 June 1984, Sungei Buloh in May 1989, Sime Road in October 1992, and November 2007. Wells (1999: 107) noted that the species is a vagrant in Peninsular Malaysia and highlighted that the sightings in 1984 and 1989 may have been wild sightings; captive birds were ruled out since the sightings comprised of adults and juveniles. Traded birds tended to be of a uniform age, since birds would be taken as fledglings.

Central Catchment Nature Reserve (CCNR) & Fringes

Possibly first for the season, a Forest Wagtail, Dendronanthus indicus, was spotted in flight on 2 September 2019 at Jelutong Tower by Francis Yap. Another was spotted within CCNR on 6 September 2019 by Dillen Ng; who also spotted an Arctic Warbler, Phylloscopus borealis, on the same day.  Also on 6 September 2019, an Eastern Crowned Warbler, Phylloscopus coronatus, was spotted at Jelutong by Francis Yap. On 10 September 2019, a Red-legged Crake, Rallina fasciata, was seen skulking about within the CCNR by Timothy Chua Jia Yao.

Chestnut-bellied Malkoha spotted from Jelutong Tower on 13 September 2019 by Alan Owyong

Jelutong proved to be a good location to observe other species, which included a Chestnut-bellied Malkoha, Phaenicophaeus sumatranus, on 13 September 2019 (Alan Owyong), and five Crested Honey Buzzard, Pernis ptilorhynchus, perched on a tree in the rain on 14 September 2019 (Tan Kok Hui). It was also from this vantage point on 27 September 2019 that two Chinese Sparrowhawk, Accipiter soloensis, three Crested Honey Buzzard, a Japanese Sparrowhawk, Accipiter gularis and an Oriental Pratincole, Glareola maldivarum, were seen flying over CCNR by Francis Yap and Richard White.

The Venus-Windsor-Lower Peirce corridor yielded the second Eastern Crowned Warbler, Phylloscopus coronatus, of the season on 2 September 2019 (Venus Loop, Ho Siew Mun). A White-rumped Shama, Copsychus malabaricus, a species vulnerable to poaching, was spotted on 4 September 2019 (Lower Peirce, Mei Hwang) while a Common Emerald Dove, Chalcophaps indica, was seen on 5 September 2019 (Venus Loop, Terence Tan), and a Banded Woodpecker, Chrysophlegma miniaceum, on 9 September 2019 (Windsor Park, Lim Sheen Taw). Further away, a torquatus race tweeddale morph Crested Honey Buzzard, Pernis ptilorhynchus, was spotted on 10 September 2019 at Upper Seletar Reservoir (Deborah Friets).

Barred Eagle Owl at Singapore Quarry on 27 September 2019 at Art Toh

Dairy Farm Nature Park (DFNP) and Singapore Quarry continues to be a high yield CCNR-fringe location.  An Eastern Crowned Warbler, Phylloscopus coronatus, was seen on 2 September 2019 (Choong YT), as was a first-for-the-season Asian Brown Flycatcher, Muscicapa daurica, on 5 September 2019 (Ho Siew Mun), a Brown-streaked Flycatcher, Muscicapa williamsoni, also on 5 September 2019 (Peter Lim), a Common Emerald Dove, Chalcophaps indica, on 7 September 2019 (Pary Sivaraman), a Sunda Scops Owl, Otus lempiji, on 10 September 2019 (Norhafiani A Majid), a Chestnut-bellied Malkoha, Phaenicophaeus sumatranus, on 11 September 2019 (Kok M Lee), and a Red-crowned Barbet, Megalaima rafflesii, on 12 September 2019 (James Quek). Fans of the Barred Eagle-Owl, Bubo sumatranus, were not disappointed. The owls appeared on 8 September 2019 (female; Martin Kennewell), 10 September 2019 (Leong Kai Kee & Low Chong Yang) and 27 September 2019 at 7:08pm (one bird; Art Toh).

Just outside DFNP, a Slaty-breasted Rail, Gallirallus striatus, was spotted in a canal by the Dairy Farm condominium on 2 September 2019 (Michael Phua), while at the nearby Bukit Batok Nature Park (BBNP), a Crimson Sunbird, Aethopyga siparaja, was reported on 7 September 2019 by Wing Chong.

Singapore Botanic Gardens

On  10 September 2019, a Crested Goshawk, Accipiter trivirgatus, was spotted near the Gardens by Brian Powell, while on 12 September 2019, a Grey-rumped Treeswift, Hemiprocne longipennis, was spotted at the gardens’ Eco Lake by Timothy Chua.

Central Singapore

Despite its much reduced size, Bidadari continued to support migrating birds. Birders visiting the grounds on 5 September 2019 were rewarded with sightings of a Eastern Crowned Warbler, Phylloscopus coronatus (T. Ramesh) and a first of the season Yellow-rumped Flycatcher, Ficedula zanthopygia (Herman Phua). Also spotted at the former cemetery were an Oriental Pied Hornbill, Anthracoceros albirostris (9 September 2019; Tracy Thu Trang Doan), a male adult Jambu Fruit Dove, Ptilinopus jambu (10 September 2019; Tracy Thu Trang Doan with Ellen Tan; and 13 September 2019, T. Ramesh), a Brown-streaked Flycatcher, Muscicapa williamsoni (10 September 2019; Krishna Gopagondanahalli), Daurian Starling, Agropsar sturninus (12 September 2019; Ramesh T.), Tiger Shrike, Lanius tigrinus (13 September 2019, T Ramesh), Crow-billed Drongo, Dicrurus annectans (27 September 2019; Pary Sivaraman), Dark-sided Flycatcher, Muscicapa sibirica (28 September 2019, Alfred Chia; 29 September 2019, Angie Cheong), the Brown-chested Jungle Flycatcher, Cyornis brunneatus (29 September 2019, Yang Chee Meng) and Brown Shrike, Lanius cristatus (30 September 2019, Joseph Lim).

A Crested Serpent Eagle, Spilornis cheela, was spotted on 6 September 2019 at Malcolm Road, while a Barred Buttonquail, Turnix suscitator, was found dazed and resting at a basketball court at Ang Mo Kio Ave 10 by Sandra Chia, who took care of the bird and released it the next morning.

Northern Singapore

A Rusty-breasted Cuckoo, Cacomantis sepulcralis, was spotted on 8 September 2019 on Coney Island (Kerry Pereira), while a Grey Wagtail, Motacilla cinerea, was spotted on 23 September 2019 at Marsiling Park by Benny Ng.

Eastern Singapore

Pulau Ubin hosted several interesting species of birds, including a Red-necked Stint, Calidris ruficollis, seen on 1 September 2019 among a flock of Lesser Sand Plover by Adrian Silas Tay. Four were seen the next day, on 2 September 2019, during an NParks survey, and photographed by See Toh Yew Wai. About a week later, a female Black-naped Monarch, Hypothymis azurea, was spotted on 7 September 2019 by Jason Lee, while a calling and thermalling Crested Serpent Eagle, Spilornis cheela, on 8 September 2019 caught the attention of Adrian Silas Tay. Further afield, a first-of-the-season Grey Plover, Pluvialis squatarola, arrived on Pulau Tekong on 14 September 2019 and was spotted by Frankie Cheong.

Back on the mainland, an Eastern Crowned Warbler, Phylloscopus coronatus, was spotted on 11 September 2019 at Pasir Ris Park by Feroz Ghazali, while a juvenile Laced Woodpecker, Picus vittatus, was seen on 28 September 2019 at Tampines Eco-Green by Ken Joree Tan.  Farther east, a  Green Imperial Pigeon, Ducula aenea, was spotted on 7 September 2019 at  Changi Business Park by T Ramesh, while a juvenile Eastern Yellow Wagtail, Motacilla tschutschensis, was seen on 24 September 2019 by  YT Choong.

Southern Singapore

A Dark-sided Flycatcher, Muscicapa sibirica, became the first record for the species for this year’s winter migration when it was spotted on 11 September 2019 along the Southern Ridges by Tay Kian Guan.

Blue-eared Kingfisher at Gardens by the Bay on 29 September 2019 by Lim Sheen Taw

The Gardens and Satay by the Bay parks proved to be a fruitful location in September. A  Yellow-rumped Flycatcher, Ficedula zanthopygia, was seen on 12 September 2019 by Veronica Foo and on 30 September 2019 by Lim Sheen Taw; while Lesser Whistling Duck, Dendrocygna javanica, was seen on 24 September 2019 at Satay by the Bay by Annette Russell. The next two days had reports of Amur Paradise Flycatcher, Terpsiphone incei (Caszlyn Wong and Sim Chip Chye, 25 September 2019; first for the season) and Blyth’s Paradise Flycatcher, Terpsiphone affinis, (26 September 2019, Cheong Khan Hoong & Sim Chip Chye) at Satay by the Bay. Other species include four juvenile Black-crowned Night Heron, Nycticorax nycticorax, on 27 September 2019, at Satay by the Bay (Kelvin Ng Cheng Kwan); Asian Brown Flycatcher, Muscicapa latirostris, on 28 September 2019 (Raymond Bong); a  Blue-eared Kingfisher, Alcedo meninting, on 29 September 2019, (Lim Sheen Taw); and a  Common Kingfisher, Alcedo atthis, on 30 September 2019 (Lim Sheen Taw).

Blue Rock Thrush at Pinnacle@Duxton on 25 September 2019 by David Fur

On 20 September 2019, sightings of a Blue Rock Thrush, Monticola soltarius, at Duxton Pinnacle by  Dillen Ng and others drew many to the block to see and photograph it; of these, Jojo Kuah spotted a total of two birds, of which one was a young male. Visiting Pinnacle on 26 September 2019 yielded a first for the season Pacific Swift, Apus pacificus, by Adrian Silas Tay. Two days later, on 28 September 2019, a Chestnut-winged Cuckoo, Clamator coromandus, was found along Marine Parade Road, by Jay Yip. Separately, on 23 September 2019, an Eurasian Magpie, Pica pica, the origin of which is unclear (possibly an escapee), was spotted at Sakra Road, Jurong Island, by Tan Boon Chong. Also, two Gull-billed Terns, Gelochelidon nilotica, were photographed near Sentosa on 21 September 2019, reported by Adrian Silas Tay.

Between 22 and 28 September 2019, up to four Cuthroat Finch Amadina fasciata, an introduced species, were also spotted within the garden’s grounds (Geri Lim and Jimmy Lim, respectively).

Further away at Jurong Lake, Whiskered Tern, Chlidonias hybrida, were spotted on 26 September 2019 by Tay Boon Kiat, while a Chestnut-winged Cuckoo, Clamator coromandus, was seen on 28 September 2019 by Norhafiani A Majid.

Jurong Eco-Garden continued to support bird life despite the reduction of surrounding woodland. On 11 September 2019, a Tiger Shrike, Lanius tigrinus, was spotted by Terence Tan, while a single juvenile Chestnut-bellied Malkoha, Phaenicophaeus sumatranus, was observed to have successfully fledged between 17 and 19 September 2019 (Kwok Tuck Loong, Alan Owyong and Joseph Lim). On 30 September 2019, a Brown Shrike, Lanius cristatus (confusus subspecies) was spotted by Joseph lim on the garden’s grounds.

Apart from the excitement over the Glossy Ibis at Kranji Dam, Whiskered Tern, Chlidonias hybrida, were spotted along the dam on 8 and 14 September 2019 by Martin Kennewell; a single bird on the 8^th was a moulting adult with remnants of its dark belly and dark eye stripe, while two birds were seen on the 14^th. White-winged Tern, Chlidonias leucopterus, were also observed within the reservoir on 30 September 2019 by Adrian Silas Tay.

Over at Sungei Buloh Wetland Reserve, we received reports of arriving waders through social media. On 3 September 2019, 37 Common Redshank, Tringa totanus, were spotted by Martin Kennewell, many were flagged but were too far to be deciphered. On the same day, a single Brown-streaked Flycatcher, Muscicapa williamsoni, was also seen by Martin. After making its arduous journey from the Arctic Circle, an Arctic Warbler, Phylloscopus borealis, found its way into the grounds of the reserve on 18 September 2019, making the sighting by Timothy Chua the first-of-the-season. On 20 September 2019, a Curlew Sandpiper, Calidris ferruginea, was spotted by David Li, while on 22 September 2019, a first-of-the-season Broad-billed Sandpiper, Limicola falcinellus, was spotted by Andy Dinesh and T. Ramesh. On 24 September 2019, a Purple Heron, Ardea purpurea, which is not commonly seen in the reserve, was spotted by Terence Tan.

The windswept Tuas yielded a Lesser Adjutant, Leptoptilos javanicus, on 22 September 2019 at Tuas Checkpoint (Fadzrun Adnan), a first-of-the-season Chestnut-winged cuckoo, Clamator coromandus and a first-of-the-season Malaysian Hawk-Cuckoo, Hierococcyx fugax, on 26 September 2019 (Alfred Chia).

Other birds spotted in the western reaches of the island city include a first-of-the-season Japanese Sparrowhawk, Accipiter gularis, on 13 September 2019 (Lim Kim Seng), a “huge flock” of Daurian Starling, Agropsar sturninus, at Pandan Reservoir on 27 September 2019 (Evelyn Lee), and the regular family of  Grey-headed Fish Eagle, Haliaeetus ichthyaetus, along Pandan River on 26 September 2019 (Francis Yap).

=================================================

Pelagic Sightings

On 28 September 2019, the NSS Bird Group conducted a pelagic survey along the Straits of Singapore.  Key highlights included a total of 112 Swinhoe’s Storm Petrel, Oceanodroma monorhis, a far cry from the previous record of 532 birds in September 2018, as well as the fourteen Red-necked Phalaropes, Phalaropus lobatus. Note that pelagic sightings might not be in Singapore waters.

A total of fourteen juvenile Red-necked Phalaropes, Phalaropus lobatus, were spotted on the seas north of Batam (Indonesia), the first sighting of multiple phalaropes in a flock. Three previous sightings were of single birds, two on land and one at sea.

Red-necked Phalaropes are small waders that forage by picking from the surface of the waters while swimming, often spinning about when pursuing active prey (Wells, 1999:264-265). Known as vagrants during passage seasons, the birds have so far been seen mostly in marine habitats, although one report from Singapore occurred in the flooded reclaimed land in Tuas in November 1994.

A total of fifteen adult and one juvenile Aleutian Terns, Sterna aleutica, were spotted, as were 55 Bridled Terns, Sterna anaethetus, with two flocks  of 18 and 7 flying eastwards in the direction of Horsburgh Lighthouse. Two adult and two juvenile Common Terns, Sterna hirundo,  were resting on flotsam, while 24 Swift Terns, Thalasseus bergii, (formerly Great Crested) and 10 Lesser Crested Terns, Thalasseus bengalensis, with four being unidentified, were seen. A total of six Little Terns, Sterna albifrons, were also seen and these may be winter visitors.

2019 ANNUAL BIRD CENSUS REPORT

By Lim Kim Chuah

Asian Openbill at SBWR, 24 March 2019, by Geoff Lim

The 2019 Annual Bird Census (ABC) was conducted on 24 March. Weather was generally fine at all the 17 sites covered. Another three sites on Ubin which were counted on 10 March as part of the Comprehensive Ubin Survey Monthly Survey were also added. This brings the number of sites counted to 20. The three sites counted on Ubin represented the sites which were traditionally counted during the ABC.

A total of 5,575 birds was counted, a 66% increase (2,207) compared to 2018. The number of species counted was 143 species, an increase compared to 137 species in 2018. The increases in both numbers and species counted in 2019 compared to 2018 could be due to the increase in the number of sites counted, 20 versus 17.

Some highlights from this year’s census include:

• Asian Openbill – 1 at Buloh Route 1
• Ashy Drongo – 1 at Telok Blangah
• Black Bittern – 1 each at Bishan Park and Dairy Farm Nature Park
• Black-browed Reed-Warbler – 1 at Kranji Marsh
• Blue-rumped Parrot – 4 at Bukit Batok West (Sadly, this is likely to be the last year that this site will be covered as the place is currently being developed into the Tengah New Town)
• Blue-winged Pitta – 1 at Lower Pierce and at Bukit Batok West and 3 at Poyan
• Chestnut-bellied Malkoha – 1 at Poyan
• Chestnut-winged Cuckoo – 1 at Halus
• Cinnamon Bittern – 1 at Buloh Route 2 and 1 at Kranji Marsh
• Crested Serpent Eagle – 1 at Malcolm Park
• Dark-sided Flycatcher – 1 at Lower Pierce Reservoir
• Great-billed Heron – 2 at Buloh Route 1, 1 at Buloh 2, 1 at Lower Seletar, 2 at Ubin East
• Green Imperial Pigeon – 1 at Pasir Ris Park
• Large Hawk Cuckoo – 1 at Pasir Ris Park
• Lesser Adjutant – 2 at Buloh Route 1 and 1 at Kranji Marsh
• Lesser Whistling Duck – 11 at Buloh Route 2
• Little Grebe – 2 at Lorong Halus and 1 at Ubin East
• Oriental Pratincole – 2 at Ubin West
• Pallas’s Grasshopper Warbler – 1 at Kranji Marsh
• Straw-headed Bulbul – 46 counted at 8 locations with most of them from Ubin
• Violet Cuckoo – 2 at Poyan
• Watercock – 1 at Kranji Marsh

Despite the increase in number of birds counted this year compared to 2018, the total is still below the last 10 years’ average of 7,356. This could be attributed to the lesser number of sites counted due largely to the lack of manpower which meant some key sites like Sungei Mandai had to be left out in 2019.

Chart below shows the total number of birds and species counted from 2010-19:

Chinese Garden turned out to be the site with the highest number of birds counted (432). And Kranji Marsh remained the site with the highest number of species counted (73).

Chart below shows the number of birds counted at each site:

Chart below shows the number of species counted at each site:

And again, it was not surprising that our ubiquitous Javan Myna is the most numerous birds counted, reclaiming its position from the Asian Glossy Starling which it relinquished to in 2018.

NSS Bird Group would like to thank the following volunteers for participating and helping with the census. Without their support, we would not have been able to continue to monitor the state of the birdlife here in Singapore all these years.

Singapore Bird Report – August 2019

by Geoff Lim & Tan Gim Cheong (ed.)

Two non-descript little brown birds (known by birders worldwide as “little brown jobs”) dominated everyone’s attention during the first portion of August 2019. Also reported were the arrival of our familiar migrants, such as the plovers, sandpipers and Common Kingfisher, across the island.  

A visiting Brown-streaked Flycatcher Muscicapa williamsoni turned up in an urban park located within Choa Chu Kang on 9 August 2019 (Lim Joseph) and was present until 16 August 2019. The bird was distinguished from other flycatchers by a distinct pattern of its  wing coverts and tertials. Sometimes considered a race of the Asian Brown Flycatcher Muscicapa daurica, this species is known to breed in SE Myanmar, S Thailand to NW Malaysia. Non-breeding birds have been reported at Singapore, Sumatra and W Borneo (Clement & Bonan, 2019).

When the excitement over this little brown job dissipated somewhat, the news of a Mangrove Whistler Pachycephala cinerea at Jurong Eco-Garden electrified the community of local birders and photographers alike. Discovered on 19 August 2019 by Andrew Wood, who reached out through Instagram, for the identify of the bird, it continued to be seen until 26 August 2019 (Feroz Ghazali). Mangrove Whistlers previously recorded on mainland Singapore were mainly confined to the east in places such as Pulau Ubin and Pasir Ris Park. We can only speculate whether this brief western sighting was of a bird fleeing development in southern Johor or part of a small resident population lurking in the west.

The Mangrove Whistler is more likely to be seen at Pulau Hantu Besar, a short boat ride from the mainland. It is also found at Pulau Tekong. Historically, there are even records from Sungei Buloh Wetland Reserve.

Central Catchment Nature Reserve (CCNR) & Fringes

On 2 August 2019, a Barred Eagle-Owl Bubo sumatranus perched in a tree along the Treetop Walk surprised Naomi Kim, who reported the sighting. Seven days later on 9 August 2019, a Chestnut-winged Babbler Stachyris erythroptera was heard within the CCNR boundaries by Martin Kennewell.  A House Swift Apus nipalensis was subsequently spotted within the reserve on 23 August 2019 by Oliver Tan.

From the Singapore Quarry came a report of a Violet Cuckoo Chrysococcyx xanthorhynchus, on 1 August 2019 (Herman Phua). The quarry’s family of two adult and one juvenile Barred Eagle-Owl Bubo sumatranus received a strong following and were variously reported to have appeared on 1 August (Wee Boon), 7 August (Norhafiani A. Majid), 9 August (Liz How – male & juvenile), 12 August (Low Choon How), 19 August (John Marriott), 21 August (Francis Yap), 24 August (Art Toh) and 26 August (Raymond Poon).

Further afield at Bukit Batok Nature Park (BBNP), an adult Little Spiderhunter Arachnothera longirostra was reported to be feeding two juveniles on 15 August 2019 by Sim Chip Chye, who also reported that he encountered two juveniles the day before (14 August 2019). Also spotted within the Park was a Common Emerald Dove Chalcophaps indica on 25 August 2019 by Lim Sheen Taw; Van Hasselt’s Sunbird Leptocoma brasiliana on 26 August 2019 by Terence Tan; and three Violet Cuckoo Chrysococcyx xanthorhynchus on 30 Aug 19 by Dave Koh and Sim Chip Chye.

Singapore Bird Report – July 2019

by Geoff Lim & Tan Gim Cheong (ed.)

July 2019 was an amazing month, with the first record of the Pied Stilt, not just occurring, but also breeding, in Singapore; and the first breeding record of the rare Black-winged Stilt, so far only known as a visitor. The month also closed with the complete loss of a brood of 11 ducklings of a pair of Lesser Whistling Ducks.

First record of Pied Stilt in Singapore.

In July 2019, Frankie Cheong reported the first record of the Pied Stilt Himantopus leucocephalus in Singapore, on the new reclaimed land around Pulau Tekong. It was on 17 July 2019 that he saw an adult Pied Stilt and four juveniles that appeared to associate with the adult. The four juvenile stilts were seen again on 23 July 2019.

Just three days later, on 20 July 2019, he found that a pair of Pied Stilts were nesting! The nest contained one egg on 20 July 2019, and by 23 July 2019, the nest yielded four eggs. On 27 July 2019, the Pied Stilts were still sitting on their eggs.

The rare Black-winged Stilts

A rare Black-winged Stilt Himantopus himantopus was also seen in the same vicinity on 17 July 2019, and again on 23 July 2019, fighting with the Pied Stilt.

First breeding record of Black-winged Stilt in Singapore.

On 25 July 2019, Frankie stumbled on yet another nest with four eggs. This time, it belonged to a pair of Black-winged Stilts, which was unexpected as these birds have so far been known as rare migrants. By 27 July 2019, one chick was visible and tended to by its parents, while the nest only had one egg visible. The two other eggs had disappeared. By 29 July 2019, the Black-winged Stilt’s nest was empty, while two chicks were seen nearby, in the presence of two adult birds.

Black-winged Stilt with chick on 27 July 2019, by Frankie Cheong.

The Black-winged Stilt is widely distributed and is found from France and Iberia S to sub-Saharan Africa and Madagascar, and E to C Asia and NC China, Indian Subcontinent (including Sri Lanka), Indochina and Taiwan; winters S to Africa (Pierce and Kirwan, 2019), while the Pied Stilt, also known as the White-headed Stilt, occurs in Sumatra and Java, E to New Guinea, and S to Australia, Tasmania and New Zealand; winters N to Philippines, Greater Sundas and Sulawesi, and as far as Sri Lanka (Pierce and Kirwan, 2019). Historically, the Black-winged Stilt is listed as the only species of stilt found in the Malay Peninsula (Wells, 1999:273-274).

Hitherto, the Black-winged Stilt has been listed as a rare migrant to Singapore. The last three sightings were at the main hide at Sungei Buloh Wetland Reserve in November 2011, Punggol Barat in December 2012 and Kranji Marsh in November 2015. Hence, Frankie’s breeding records presents new knowledge on the status of the bird in Singapore.

The Pied Stilt had previously been considered a sub-species of the Black-winged Stilt (Pierce and Kirwan, 2019) and is notably a largely Indonesian/Australasian species. In recent years, it has more frequently been accorded full species status (Sonobe & Usui, 1993; Robson, 2005). There are no previous records of the Pied Stilt in Singapore, much less a breeding record, therefore Frankie’s sightings constitute the first records of the Pied Stilt in Singapore.

Central Catchment Nature Reserve (CCNR) & Fringes

While resident species continued to hold sway, early migratory species have begun to reach our shores. In the heart of the CCNR, observers reported regular forest residents such as the Violet Cuckoo Chrysococcyx xanthorhynchus on 10 July 2019 (Francis Yap), Black-headed Bulbul Pycnonotus atriceps on 13 July 2019 at Jelutong Tower (Joseph Lim), the Chestnut-winged Babbler Stachyris erythroptera on 23 July 2019 (Martin Kennewell), Short-tailed Babbler Malacocincla malaccensis on 23 July 2019 (Martin Kennewell – 2 heard) and on 25 July 2019 (Kelvin Ng Cheng Kwan – 1 bird seen on trail to Jelutong Tower), and Greater Green Leafbird Chloropsis sonnerati (Evelyn Lee – female at Jelutong Tower). A migratory Brown-streaked Flycatcher Muscicapa williamsoni was reported as being seen on 22 July 2019 by Raghav N.

CCNR fringe parks also received a fair amount of attention. Dairy Farm Nature Park (DFNP) hosted a conference of Van Hasselt’s Sunbird Leptocoma brasiliana between 1 and 4 July 2019 (Peter Lim), beginning with 11 individuals on 1 Jul 2019, to 7 birds and eventually 4 birds by 4 July 2019. The Chestnut-bellied Malkoha Phaenicophaeus sumatranus was spotted on 27 July 2019 (Yeong Wai Kai) and a female Thick-billed Pigeon Treron curvirostra was seen on 31 July 2019 (Roberta Cheok). Along the Rail Corridor, a Tanimbar Corella Cacatua goffiniana was spotted on 5 July 2019 (Lim Sheen Taw).

Further away at the Singapore Quarry, a foraging Brahminy Kite Haliastur indus was spotted on 3 July 2019 (Kelvin Ng Cheng Kwan), a pair of Barred Eagle Owl Bubo sumatranus and its juvenile were variously spotted on 16 July 2019, from 21 to 25 July 2019 by Art Toh and friends, and heard on 28 July 2019 by Yong Ding Li and Geoff Lim; while a Violet Cuckoo Chrysococcyx xanthorhynchus was spotted on 30 July 2019 by Francis Yap. Observers also noted the presence of the Brown Hawk Owl Ninox scutulata at Hindhede Park on 4 and 26 July 2019 (Terence Tan and Joseph Lim).

Eastern Singapore

Singapore’s eastern flanks contain habitats that yielded surprises. Pulau Ubin delivered spectacular species, such as a rare Black-and-Red Broadbill Cymbirhynchus macrorhynchos discovered during a joint NParks-NSS Ubin survey on 7 July 2019, a Crested Serpent Eagle Spilornis cheela on 2 July 2019 by Feroz Ghazali, while the Black-winged Flycatcher-shrike Hemipus hirundinaceus put up two appearances on 14 and 21 July 2019 at Chek Jawa for Francis Yap. There were also shorebirds lingering farther away – three Whimbrel Numenius phaeopus and two Common Sandpiper Actitis hypoleucos spotted on 18 July 2019 by Feroz Ghazali, and Grey Plover Pluvialis squatarola, Common Greenshank Tringa nebularia and more Whimbrel on 21 July 2019 by Francis Yap.

Pasir Ris Park continued to support Yellow-crested Cockatoo Cacatua sulphurea (14 July 2019; Steven Cheong), the adult and juvenile Spotted Wood Owl Strix seloputo (28 July 2019; Jimmy Ng), the one-eyed Buffy Fish Owl Ketupa ketupu (28 July 2019; Jimmy Ng), and the juvenile Blue-eared Kingfisher Alcedo meninting with a deformed foot (31 July 2019; Dean Tan). Nearby at the Sungei Tampines Canal East, Little Tern Sternula albifrons had been seen earlier on 1 July 2019 foraging above the waters by Alvin Seng.

Changi Business Park continued to be a stronghold for the Green Imperial Pigeon Ducula aenea, which was reported on 14 July 2019 (T. Ramesh) drinking water in the canal, and on 19 July 2019 at a more conventional location. Also spotted was an early arriving Grey Wagtail Motacilla cinerea, seen on 17 July 2019 by T. Ramesh.

Gardens by the Bay gave nature lovers much grief and anxiety when the ducklings belonging to a pair of Lesser Whistling Duck Dendrocygna javanica were systematically decimated through the course of the month. (From 11 ducklings on 27 June 2019), by 1 July 2019, there were seven ducklings, as counted by Isabelle Lee and other birders. Staff from the Gardens took pains to build a floating platform for the birds to provide a safe haven from suspected underwater predators. Despite everyone’s best effort, the family was eventually reduced to four survivors by 22 July 2019 (Ronnie Koh), as individuals were picked off by predatory fish lurking beneath the murky waters under the lotus pads. On 24 July 2019, the family decided to move to the ponds at Gardens by the Bay East, and by 25 July 2019, the family was down to a single duckling (Mary Yeo). Then, on 26 July 2019, there were no more ducklings (Jeremiah Loei).

Barely a kilometre away, another family of birds captured the attention of photographers and birders. A pair of Masked Lapwing Vanellus miles made a nest out of a scrape on the ground next to a construction site at Marina Bay East. Four eggs were reported on 16 July 2019, which eventually hatched by 19 July 2019. The chicks were rescued by construction workers when they could not surmount the kerb when their parents moved to the golf course across the construction site.

Further away, White-rumped Munia Lonchura striata were reported at Telok Blangah Hill Park on 19 July 2019 by John Marriott, who also reported Yellow-crested Cockatoo Cacatua sulphurea at Sentosa on 23 July 2019.

Western Singapore

The Kranji Marshes and surrounding habitat comprising Turut Track and Neo Tiew Harvest Lane received reports of migrants and residents alike. Two Red-wattled Lapwing Vanellus indicus were reportedly inspecting a hole at Turut Track on 3 July 2019 by Steven Wong, who also reported the sighting of a Changeable Hawk-Eagle Nisaetus cirrhatus in the vicinity on the same day. A Cinnamon Bittern Ixobrychus cinnamomeus was reportedly seen on 7 July 2019 at Neo Tiew Harvest Lane by William Legge, who noted that “a small bittern uniformly salmon cinnamon coloured flew away from us”. Two Straw-headed Bulbul Pycnonotus zeylanicus were spotted on 17 July 2019 within Kranji Marshes by Vincent Chin, while a juvenile Banded Bay Cuckoo Cacomantis sonneratii was seen on 28 and 29 July 2019 by Yeong Wai Kai; the young cuckoo was being fed by a Common Iora Aegithina tiphia on 28 July 2019. An adult Scaly-breasted Munia Lonchura punctulata was also seen regurgitating food for three young birds on 30 July 2019 at Kranji Marsh by Yeo Seng Beng. Migratory Wood Sandpiper Tringa glareola and Little Ringed Plover Charadrius dubius were reported to have arrived at Neo Tiew Harvest Lane on 28 July 2019 by Art Toh.

Singapore Raptor Report – Late Spring Migration, April-June 2019

Summary:

Only four migrant raptor species were recorded in the April to June period. They are the regulars during this period – the Western Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon.

There were eleven records of the Oriental Honey Buzzard Pernis ptilorhyncus in April, ten in May and eight in June. At least five records in April were orientalis juveniles, as were six in May and four in June – these birds are spending the summer here in the tropics.

Five Japanese Sparrowhawks Accipiter gularis were recorded between 1-12 April. Singles at Ulu Pandan on 1st April, Mount Faber on 5th April, Pulau Ubin on 7th April, and Dairy Farm Nature Park on 8th April & 12th April. These are the last birds to leave for their breeding grounds to the north.

Seven Peregrine Falcons Falco peregrinus were recorded, all in the month of April. Notably, the individual photographed at Toa Payoh on 17th April had, on its left tarsus (leg), a ring with ‘JBP’ engraved. This bird was rescued, rehabilitated and released by the Jurong Bird Park (JBP) more than ten years ago. Another individual recorded at Haig Road on 4th April was mobbing an Oriental Honey Buzzard.

Five Western Ospreys Pandion haliaetus were recorded in the April-June period. Two at the Krani – Sungei Buloh area throughout, one at Gardens by the Bay on 3rd April, one at Jurong Lake on 27th April, and one at Pulau Ubin – Pasir Ris area on 22nd April and 8th May.

Sedentary Raptors

The Changeable Hawk-Eagle Nisaetus cirrhatus was reported to be nesting at Kranji Marsh area on 19th April, and the White-bellied Sea Eagle Haliaeetus leucogaster was also nesting at Fort Canning, with a well grown chick on the nest observed between 13-29 June. Juveniles of the Crested Goshawk Accipiter trivirgatus at Bishan (April), Pasir Ris (April – 2 birds), and Ang Mo Kio (May), and a fresh juvenile Changeable Hawk-Eagle at Pasir Ris (April & May) suggest that breeding had occurred in the preceding months.

A nest, presumably that of the Brahminy Kite Haliastur Indus, based on the size of the nest and the observer’s experience, was recorded at the Rail Corridor near Phoenix Heights on 27th June. Also, a pair (a male & a female) of adult Crested Goshawks was recorded at South Buona Vista Road on 13th June, as were two adult Grey-headed Fish Eagles Haliaeetus ichthyaetus, probably a pair, at Sungei Ulu Pandan, also on 13th June.

One Crested Serpent Eagle Spilornis cheela was present at Goldhill Avenue area in April and May, with the exception of 27th April when two birds were seen. In addition, one individual was recorded at Pulau Ubin (April & May), one at Toh Tuck Road (25th May), and one at Sentosa on 10th & 15th April. An adult Peregrine Falcon of the resident ernesti race was photographed at Jurong East on 2nd June, perched on a TV antenna consuming a bird.

Nocturnal Raptors

A family of Spotted Wood Owls Strix seloputo comprising two adults and a recently fledged chick was recorded at Cashew Road on 1st May, the nesting was first noted in March and the chick had fallen from the nest during the nesting period, but all was well after intervention by ACRES. On 9th June, a family of Buffy Fish Owls Ketupa ketupu, including a recently fledged juvenile, was photographed at Jurong Lake. As an indication of another successful nesting attempt, a juvenile Barred Eagle-Owl Bubo sumatranus was photographed at Bukit Timah on 28th June. Notably, a Barred Eagle-Owl was recorded at Bukit Brown, a new locality for the species, on 27th April.
