The 11th Singapore raptor watch was held on Saturday, 3 November 2018 and involved 42 participants. The weather was mostly partly cloudy. There were seven raptor watch sites and the numbers counted at each site varied from a high of 193 to a low of 19 birds. A total of 556 raptors were counted, including 437 raptors representing 8 migrant species and 69 raptors of 6 resident species. A further 50 raptors could not be identified to species level.

Summary:
Number of raptors – 556
– 437 migrant raptors.
– 69 resident raptors.
– 50 un-identified raptors.

Number of species – 14
– 8 migrant species.
– 6 resident species.

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 Hill, due to ongoing works at the Japanese Gardens, and the shifting of the Tuas site slightly north to Tuas View Drive.

The highest number of raptors recorded was at Telok Blangah Hill Park (193 birds), followed by Puaka Hill, Ubin (108 birds) and Jurong Hill (105 birds). Note that the count at Jurong Hill ended earlier, at 2:15pm, due to manpower constraints. Rather surprising was the low numbers at Tuas for the second year running.

Figure 2 : Total count by Site

The peak hours for migrant raptors were between 10am to 2pm, with a high of 133 migrant raptors in the 11am to 12pm period. In the morning, 16 migrant raptors were recorded in the first hour between 8-9am, and in the later part of the afternoon, another 16 were recorded in the last 2 hours of observation.

The Oriental Honey Buzzard (OHB) reclaimed the top spot, with 248 birds counted. The largest number of OHB were at Jurong Hill (81 birds) despite the count ending earlier, Telok Blangah Hill Park (72 birds) and Kent Ridge Park (38 birds).  There were 120 Japanese Sparrowhawks, similar to last year. The main bulk of the Japanese Sparrowhawks (66 birds) were counted at Telok Blangah Hill Park. There were 30 Chinese Sparrowhawks, and most of them were recorded at Telok Blangah Hill Park (15 birds), and Puaka Hill, Pulau Ubin (14 birds).

Grey-faced Buzzards put up a good show this year, with 11 counted across four sites: six at Puaka Hill, two each at Telok Blangah Hill Park and Lorong Halus Wetlands, and an individual at Jurong Hill. Three Peregrine Falcons were recorded: singles at Jurong Hill, Telok Blangah Hill Park and Lorong Halus. Only one Western Osprey was recorded – at Jurong Hill and one Black Kite – at Tuas.

The figure below provides a snapshot of the number of raptors according to the three categories – migrant, un-identified & resident raptors, at the 7 sites. A larger proportion of the migrant raptors were detected in the southwest stretch from Jurong Hill to Kent Ridge Park to Telok Blangah Hill Park, with a peak of 159 migrant raptors at Telok Blangah Hill Park.

Singapore Bird Report – January 2019

Migratory and resident species are seen all over the island as the former settle down in Singapore after their arduous journey from the northern hemisphere. One remarkable species encountered this month was the Yellow-vented Flowerpecker, a rare resident; up to two birds were seen at the summit of Bukit Timah Hill, sparking an uphill climb by many birders to see and photograph this rare gem. As a result, several other species of migrants were also spotted during the first half of the month.

Singapore Raptor Report – December 2018

Common Buzzard, adult pale morph with lizard tail protuding from its bill, on 1 Dec 2018, at the junction of Holland Road and North Buona Vista Road, by Art Toh.

Summary for migrant species:

A rare Short-toed Snake Eagle surprised and delighted a small group of birders who managed to get crisp photographs of the raptor as it flew over Changi Business Park on 5th December, and disappeared – a one-day wonder as it usually is for this species in Singapore. On the other side of the island, at the junction of Holland Road and North Buona Vista Road on 1st December, an uncommon Common Buzzard feeding on a lizard gave Art Toh many photo opportunities. A rare Imperial Eagle was reportedly seen at Neo Tiew Harvest Lane on the 15th.

A rufous morph Oriental Scops Owl was found on 5th December at Dairy Farm Nature Park. Then, a grey morph Oriental Scops Owl showed up in the same vicinity on the 9th, the same date as the year before! Both morphs were present on 9th and 10th December. Thereafter only the rufous morph was reported to be around until the 15th. These two birds display amazing site fidelity, returning to the same spot for the 3rd season in a row!

Eight Jerdon’s Bazas were recorded: four wintering at Changi Business Park, three at Lorong Halus on the 25th and one at Pulau Ubin on the 30th. Five Chinese Sparrowhawks were recorded: singles at Pulau Ubin, Henderson Waves & Coney Island, and two at Lorong Halus. Five Peregrine Falcons were recorded: singles at Kranji Marshes, Coney Island, Changi Business Park, Seletar Aerospace and West Coast Drive. Three Western Ospreys were recorded: one at Simpang grasslands, one at Kranji Marshes, and another at MacRitchie Reservoir.

Finally, we come to the most abundant migrant raptors. 15 Japanese Sparrowhawks and 49 Black Bazas were recorded, including 27 bazas at Lorong Halus on the 29th. The Oriental Honey Buzzard is tops again with 85 birds, including 33 birds at Tuas on the 1st.

Highlights for sedentary species:

The notable sightings for resident raptors include that of the locally rare Crested Serpent Eagle which was recorded three times: an immature at Henderson Waves on the 8th, and two sightings at Pulau Ubin, on the 7th & 31st, probably of the same bird. Another was the nesting of the Crested Goshawks at West Coast, with 2 chicks that were reported to have fledged by the time of this report. And also, a Brahminy Kite at Neo Tiew Lane 2 flying with nesting materials on the 29th.

The torquatus Oriental Honey Buzzard was recorded at Jelutong Tower on the 20th (tweeddale morph), Springside Link on the 25th, and an immature at Pasir Ris starting from the 27th (and is still around). The other resident raptors recorded were the Black-winged Kite, White-bellied Sea Eagle, Grey-headed Fish Eagles and Changeable Hawk Eagle.

Singapore Bird Report – December 2018

The Eurasian Wigeon reappears in Singapore after 31 years! December marks the end of peak annual migration season, and the year-end holidays. As holiday makers make their way to colder climes, birds continue to stream into Singapore, yielding surprises like the Eurasian Wigeon, Cotton Pygmy Goose, Sakhalin Leaf Warbler, and the Oriental Scops Owl duo.

Eurasian Wigeon 

On the morning of 23 December 2018, an Eurasian Wigeon Anas penelope was spotted within the confines of Kranji Marsh by Martin Kennewell. This remarkable sighting represents one of only two records of the Wigeon in Singapore; the last being an immature female associating with Whimbrel flocks in the ponds, mudflats and mangroves around Sungei Buloh between December 1986 and February 1987. It also underscores the importance of the Kranji freshwater habitat in supporting wetland species sensitive to human activity.  The closest known breeding territory for the bird is in Mongolia, although the species occurs throughout Asia and southeast Asia. Although listed as being of Least Concern on the IUCN Red List, this species is sensitive to human activity and faces pressure from habitat loss and hunting (Birdlife 2017).

Cotton Pygmy Goose

While many were still reeling from the appearance of the mega-rare Eurasian Wigeon, news of a scarce Cotton Pygmy Goose Nettapus coromandelianus arriving at Lorong Halus on Christmas Eve rippled across social media. The last known appearance of the dimunitive duck in Singapore took place on 15 February 2016 at Satay by the Bay’s main pond; as the 2016 occurrence turned out to be a one-day bird, many birders and photographers abandoned their Christmas Eve plans for the afternoon to descend on the ponds of Lorong Halus. They were not disappointed as the bird continued to stay through Christmas till the end of 2018.

The Cotton Pygmy Goose is found across India, southern China, southeast Asia, parts of Papua New Guinea and northern Australia. Listed on IUCN’s Red List as being of Least Concern, research is still needed to better understand threats and conservation issues regarding the bird (Birdlife 2016).

Oriental Scops Owl

To the delight of many birders, the grey and rufous morph Oriental Scops Owl Otus surnia returned to the trees adjacent to Wallace Centre at Dairy Farm Nature Park (DFNP). On 5 December 2018, Lim Kim Keang spotted the rufous morph, which was joined by the grey morph on 9 December 2018. On 19 December 2018, David Tan reported the collection of a dead rufous morph Oriental Scops Owl from the vicinity of Eng Neo Avenue, an area abutting the CCNR. The bird may have crashed into a window before landing into a water feature, where it was subsequently retrieved from.

Central Catchment Nature Reserve

As expected, reports of migrants dominate in the month of December. Apart from the reports of the Oriental Scops Owl and Sakhalin Leaf Warblers Phylloscopus borealoides, a Green-backed Flycatcher Ficedula elisae was observed just before Jelutong Tower on 17 December 2018 by Oliver Tan. Just before the year ended, a Hooded Pitta Pitta sordida appeared at the foot of Bukit Timah hill on 30 December 2018, as reported by Chin Yee Hong.

Central Singapore

A Cinnamon Bittern Ixobrychus cinnamomeus was sighted at Bishan Park on 10 December 2018 by Ng Kian Chye. An unhappy report on 30 December 2018 was made by Nicholas Chiam, who found a Hodgson’s Hawk Cuckoo Hierococcyx nisicolor that had expired at the base of Cathay Building along Dhoby Ghaut; a casualty from possibly colliding with the building while in flight. An uncommon Brown-streaked Flycatcher Muscicapa williamsoni was photographed at Gardens by the Bay on 26 December 2018 by Ng Wei Khim.

Northern Singapore 

Apart from the Cotton Pygmy Goose reported on Christmas Eve and described above, Halus Wetland Centre also yielded a Baillon’s Crake Porzana pusilla, which was spotted on 27 December 2018 by Alfred Chia, and subsequently photographed over the next few days by an assembly of photographers searching for the goose. A Hooded Pitta Pitta sordida was reported from Rivervale Cresent on 4 December 2018 by Jeff Long.

Eastern Singapore

A rare Slaty-legged Crake Rallina eurizonoides was reported to be in a basement carpark at Haig Road area on 29 December 2018, by Martin Kennewell. Another Hooded Pitta was reported from Simei Block 147 on 6 December 2018 by David Tan. Arising from the Ashy Drongo Dicrurus leucophaeus reported in November, several interesting species were reported from the vicinity of Changi Business Park. These include a Short-toed Snake Eagle Circaetus gallicus reported on 5 December 2018 by Melinda Chan, a Chestnut-winged Cuckoo Clamator coromandus on 8 December 2018 by Lim Kim Keang, a White-shouldered Starling Sturnia sinensis on 11 December 2018 by Joseph Lim, and a Jerdon’s Baza Aviceda jerdoni on 13 December 2018 by Stuart Campbell.

Further afield, a Grey Plover Pluvialis squatarola and Terek Sandpiper Xenus cinereus were seen on Pulau Tekong on 19 December 2018 by Frankie Cheong, while a pair of Cinnamon-headed Green Pigeons Treron fulvicollis and another Jerdon’s Baza were spotted on Pulau Ubin on 30 December 2018 by Diane Campbell.

Southern Singapore

A Common Buzzard Buteo buteo was seen at Holland Road on 1 December 2018 by Art Toh, a first for the location. Arising from a fruiting fig tree at Telok Blangah Hill Park, several species of birds were reported from the location, including a Ferruginous Flycatcher Muscicapa ferruginea on 5 December 2018 and a Zappey’s or Blue-and-White Flycatcher Cyanoptila cumatilis or C. cyanomelana on 12 December 2018 by Anthony Nik and Jeremiah Loei, respectively. These were first for the location as well. A House Sparrow Passer domesticus was spotted at Gardens by the Bay on 23 December 2018 by Anthony Nik.

Western Singapore

A juvenile Grey-headed Fish Eagle Haliaeetus ichthyaetus spotted at Chinese Garden on 8 December 2018 by Loke Peng Fai. An Imperial Eagle Aquila heliaca was reportedly seen on 15 December 2018 at Harvest Lane by Lim Kim Seng. The Eurasian Wigeon described above was seen at Kranji Marsh on 23 December 2018 by Martin Kennewell, while a Watercock Gallicrex cinerea was spotted at the same Marsh on Christmas Day (25 December 2018) by Art Toh. Boxing Day (26 December 2018) birding yielded a Forest Wagtail Dendronanthus indicus at Sungei Buloh Wetland Reserves for Feroz, while an Eye-browed Thrush Turdus obscurus was seen at West Coast Drive on 28 December 2018 by Tay Kian Guan. Finally, we received delightful news of a male Greater Painted Snipe Rostratula benghalensis with three chicks at Kranji Marsh on 30 December 2018 by Hongxun.

Sakhalin Leaf Warbler

Birders and scientists acknowledge that Phylloscopus warblers represent one of the most difficult species to identify. The Pale-legged and Sakhalin Leaf Warblers are cases in point as both are remarkably similar, in fact they were previously considered conspecific, i.e. same species.

Sakhalin Leaf Warbler at the Central Catchment Nature Reserve, 14 Janaury 2019, photo by Koh Lian Heng.

Pale-legged Leaf Warblers largely come from northeast Asia, and spend their winter months in southeast Asia. Sakhalin Leaf Warblers are found from the Sakhalin Island, down large swathes of Japan, as well as along coastal China from Weihai to an area the south of Xiamen. Wintering records of the species sparsely dot places in Vietnam, Thailand, Peninsular Malaysia. As it stands, only the Sakhalin Leaf Warbler is in the NSS bird checklist, the Pale-legged has yet to be recorded.

In 2014, a team of Singapore birders comprising Lim Kim Keang, Francis Yap, Yong Ding Li, Albert Low and Con Foley worked with NUS scientists to firmly establish the species as a rare accidental visitor to Singapore (Yap, et al, 2014). Then, Lim Kim Keang heard a Leaf Warbler calling in the Central Catchment Nature Reserve; conventional wisdom suggested that this was probably a Pale-legged Leaf Warbler. However, analysis of the recorded calls and comparisons with the known calls of the two species in question showed that the bird was a Sakhalin Leaf Warbler, as the calls were at a frequency lower than that of the Pale-legged Leaf Warbler.

Detective work by our Singaporean birders. Extract of sonographic records from Yap et al, (2014) showing how the calls of the Pale-legged Leaf Warbler may be distinguished from the Sakhalin Leaf Warbler by distinct differences in their frequencies.

On 27 December 2018, when several high-frequency calls were heard by Lim Kim Chuah while jogging around MacRitchie Reservoir Park, several birders ventured to determine which Leaf Warbler species that was. Their effort revealed that up to three birds were calling within an area measuring about 500m by 250m. Detailed examination by Yong Ding Li of one of the calling birds revealed that it was a Sakhalin Leaf Warbler.

Photographing the birds proved harder as they tended to be more furtive and often skulked in the darker sections below the canopies of trees, as well as descending to the darkened forest floor to forage. Several photographers managed to obtain decent photos, to reveal a bird that superficially resembles the common Arctic Warbler, but has distinguishing marks such as pinkish legs and a conspicuously long buffy eye-stripe that extends almost to the nape. The bird’s skulking behaviour, as well as its propensity to descend to the ground level, contrasts greatly with the canopy-loving Arctic Warbler.

Summary for migrant species:

November is the peak month for migrant raptor diversity and this month matched last year’s record of 18 migrant species, while the numbers – 2666 migrant raptors – more than doubled that of last year’s 1090. The Southern Ridges continued to attract raptor watchers, with Henderson Waves being the favoured spot. On 12 November, a largish accipiter showed up west of Telok Blangah Hill Park, circled a few times and headed back west. Sensing something promising, Tan Gim Cheong snapped a few pics to confirm its identity – a rare Eurasian Sparrowhawk – the 5th record for this species in Singapore. On 20 November, Oliver Tan was well rewarded for his time spent at Henderson Waves with another rare raptor – a Short-toed Snake Eagle.

After last month’s single record at Kent Ridge, we had three records of the rare Greater Spotted Eagle, all juveniles: one on the 3rd flying high over Changi Business Park, photographed by Zacc HD; one on the 4th at Henderson Waves, photographed by See Toh Yew Wai; and another one on the 10th, also at Henderson Waves, photographed by Tan Kok Hui. On the 6th, Low Choon How located a Northern Boobook at Tuas and another was found dead at a condo on the 10th, collected by David Tan. Two juvenile Black Kites were recorded: one on the 3rd at Tuas and another on the 8th at Hindhede Nature Park, both photographed in flight.

There were two flybys of the uncommon Eastern Marsh Harrier at Turut Track, an adult male on the 4th, photographed by Low Choon How; and a juvenile on the 5th, photographed by Francis Yap. On the 11th, while guiding a student group during the bird race, Adrian Silas Tay photographed a rare Pied Harrier, a juvenile, at Sungei Buloh Wetland Reserve.

Short-toed Snake Eagle, 20 Nov 2018, Henderson Waves, by Oliver Tan

An uncommon Common Buzzard was photographed at Pasir Ris on the 2nd, and Dr Chaiyan remarked that it was a refectus juvenile. This month’s 11 Grey-faced Buzzards exceeded last month’s six. On the 3rd, five were recorded at Henderson Waves, two at Lorong Halus; on the 6th, two at Henderson Waves; and on the 10th, two at Lazarus Island; all being recorded between 10am to 1pm.

The uncommon Jerdon’s Baza was recorded twice, on the 19th at Preston Road perched on a tree, and on the 23rd flying over Henderson Waves. As Preston Road is near Henderson Waves, it may have been the same individual on both dates. Another uncommon raptor, the Common Kestrel was photographed at Neo Tiew Lane on the 29th.

Fifty nine Chinese Sparrowhawks were recorded, many of them over Henderson Waves, while one adult female seemingly returned to winter at Ang Mo Kio. Eight Peregrine Falcons and five Western Ospreys were also recorded. There was a report of an immature Rufous-bellied Hawk-Eagle (which is often confused with the resident Changeable Hawk-Eagle) rescued on the 4th at Pasir Ris and subsequently released.

Finally, we come to the most abundant migrant raptors. 209 Japanese Sparrowhawks were recorded, many of them at Henderson Waves. From 35 birds last month, we had 664 Black Bazas this month, with a flock of 200 birds on the 8th at Telok Blangah Hill Park. The Oriental Honey Buzzard is tops again with 1698 birds, with a day high of 488 birds, which included a stream of 200 birds at noontime, at Tuas on the 10th.

Highlights for sedentary species:

Both records of the torquatus Oriental Honey Buzzards were of the non-tweeddale form; one perched at Mandai on the 14th, and another in flight at Telok Blangah Hill Park on the 28th.

At Bukit Timah on the 8th, Richard White photographed an immature White-bellied Sea Eagle that had lost all its secondaries and half of its primaries on its right wing, and most of its tail feathers. Amazingly, it could still fly!

Nesting activities were observed for three resident species. A White-bellied Sea Eagle flying with a 2m long stick at West Coast, a Brahminy Kite flying with a smaller stick on the 22nd, a Grey-headed Fish Eagle perched near a nest at Punggol and a pair of Changeable Hawk-Eagles at their nest at Mount Faber. The other resident raptors recorded included the Crested Goshawk and Black-winged Kite.

Singapore Bird Report – November 2018

November 2018 sprang a number of surprises, with the first record of an Eurasian Skylark, followed by many other rarities. As migration continued in earnest, news of surprise visits by rare species with patchy records such as the Citrine Wagtail, Green Sandpiper, Stejneger’s Stonechat, etc, made for an exciting time. This season also marks the return of the Indian Paradise Flycatcher at Sungei Buloh. Will the later months bring back the Booted Warbler and Band-bellied Crake? Birders, keep your eyes peeled!

Passerine Surprises in the West

On 3 November 2018 at Pandan Reservoir, Angela Chua photographed a brown bird that looked like the common Paddyfield Pipit, however Martin Kennewell recognised it as an Eurasian Skylark Alauda arvensis, a first for Singapore. The bird was present till 17 November 2018. This species has a wide range that stretches from Europe, across North Africa, Middle East and Central Asia, through the Indian subcontinent to China and Korea (Birdlife, 2018a), and is vagrant to Borneo.

On Bird Race Day, 11 November 2018, Team “Friends of Buloh” saw a Stejneger’s Stonechat Saxicola stejnegeri at Harvest Lane and subsequently some other teams were fortunate to catch up to it. This species is a rare passage migrant and winter visitor. The last records of the stonechat’s occurrence in Singapore were in February 2015 and February 2012.

A week later on 18 November 2018, an early morning post on social media by Martin Kennewell and Adrian Silas Tay on a Black-headed Bunting Emberiza melanocephala found at Harvest Lane galvanised many birders who flocked to the waterlogged fields overgrown with Neptunia shrubs to see it. Essentially a Central Asian bird, this species is more usually encountered in south-eastern Europe through the Balkans to Iran and western India, though there have been reports of vagrants appearing in China, Taiwan, Japan and Sabah (Copete, 2018). In the overgrown fields, the bird concealed its origins well. However, a few birders managed to get exceptionally clear photos, which showed that the bird suffered from unusual feather wear of the type commonly seen in captive birds.

Also on the same day, 18 November 2018, we were greeted by the surprising news of an Indian Paradise Flycatcher Terpsiphone paradisi, our second record for this species. Spotted by Kozi Ichiyama at the Sungei Buloh Wetland Reserve (SBWR), this species made waves in local birding circles when it was first reported at the same location around 25 March 2018, during the spring migration period.

There must be something about 18 November 2018, for Tiak Lee photographed an unusual looking wagtail amongst the many Yellow Wagtails at the National Service Resort and Country Club’s Kranji Sanctuary Golf Course. When the photos were processed several days later, Alfred Chia identified it as a very rare first winter Citrine Wagtail Motacilla citreola! On reviewing his photos, Lim Kim Keang discovered that he had photographed the same bird at the same locality four days earlier, on 14 November 2018. The last record of the species in Singapore was in December 1994, making this a 24-year gap until its latest appearance.

Shorebird Surprise

Local birders were surprised when a photograph of a rare Green Sandpiper Tringa ochropus taken on 2 November 2018 by Daniel Loh at Hide 1C Sungei Buloh Wetland Reserve (SBWR) surfaced on social media several days later, identified by Martin Kennewell. The species breeds in the northern latitudes across Scandinavia to Siberia and winters in the Mediterranean, Africa, Middle East, Indian subcontinent, south Japan, east China, the Philippines and northern Borneo (Van Gils, Wiersma & Kirwan, 2018) and is listed as being of Least Concern by IUCN (Birdlife, 2018c).

Chinese Egrets

Singapore continued to host the vulnerable Chinese Egret Egretta eulophotes. Two birds were seen on 7 November 2018, and another was spotted on 24 November 2018 on Pulau Tekong by Frankie Cheong.  Preferring marine coastal and intertidal habitats, this species is known to breed in China, both Koreas, and Far Eastern Russia. However, key threats come from habitat loss from reclamation of tidal flats, estuarine habitats and other human developmental activities.

Central Catchment Nature Reserve (CCNR), BTNR & DFNP

Migrants seen within these boundaries include a Black Kite Milvus migrans photographed on 8 November 2018 at Hindhede Nature Park (James Mustafa), a Blue-winged Pitta Pitta moluccensis and a Grey Nightjar Caprimulgus jotaka on the same day at the same locality (Richard White), the latter being the first-for-the-season. A Blue-and-White/Zappey’s Flycatcher Cyanoptila cyanomelana/cumatilis was seen at Mandai Zoo on 12 November 2018 (CK Tang). Two Siberian Thrush Geokichla sibirica were spotted on 17 November 2018 (Lim Kim Chuah & Art Toh) at Dairy Farm Nature Park (DFNP). DFNP proved to be productive towards the end of the month, with an Ashy Drongo Dicrurus leucophaeus spotted on 24 November 2018 (Yeo Seng Beng), and three groups of Eye-browed Thrush Turdus obscurus, numbering 31 in total, on 26 November 2018 (Martin Kennewell).

Resident species spotted here included a Thick-billed Pigeon Treron curvirostra on 2 November 2018 at Jelutong Tower (Francis Yap), three to six Grey-headed Fish Eagle Haliaeetus ichthyaetus moving south-west together on 8 November 2018 at Bukit Timah Hill (Richard White) and a Blue-eared Kingfisher Alcedo meninting on 8 November 2018 at Hindhede Nature Park (Richard White & Alan Owyong). An Oriental Darter Anhinga melanogaster was spotted in CCNR on 9 November 2018 (Lim Kim Seng), while a flock of eight Blue-rumped Parrot Psittinus cyanurus was seen on 15 November 2018 flying over the entrance of Venus Park (Shirley Ng). Mandai Zoo proved to be fruitful also for residents, with a Black-headed Bulbul Pycnonotus atriceps, being spotted on 16 November 2018 (Thio Hui Bing).

Central Singapore

Sightings of migratory species dominated the records for locations within Central Singapore. A Blue-and-White/Zappey’s Flycatcher Cyanoptila cyanomelana/ cumatilis was spotted on 18 November 2018 at Ang Mo Kio Town Park by Loke Peng Fai, while Bidadari continued to attract interesting species, such as a female hepatic Himalayan Cuckoo Cuculus saturatus on 22 November 2018 by Con Foley and Pary Sivaraman, a rare Green-backed Flycatcher Ficedula elisae on 24 November 2018 by Goh Cheng Teng, and a Grey Nightjar Caprimulgus jotaka on 26 November 2018 (T. Ramesh).

Eastern Singapore

Five to six Daurian Starling Agropsar sturninus were seen on 3 November 2018 at Pasir Ris Park (Alvin Seng). A Greater Spotted Eagle Clanga clanga was photographed on 4 November 2018 around Changi Business Park (Zacc HD), while a Malaysian Hawk Cuckoo Hierococcyx fugax was seen at Pasir Ris Park on 17 November 2018 (Alvin Seng); a few days later on 23 November 2018, at nearby Tampines Eco-Green, a female Mugimaki Flycatcher Ficedula mugimaki was spotted (Alvin Seng). Further afield, two Ruddy Turnstone Arenaria interpres were seen on 24 November 2018 on Pulau Tekong (Frankie Cheong), while a Jerdon’s Baza Aviceda jerdoni was photographed on 30 November 2018 at Changi Business Park (James Gan).

Notable residents recorded in the east was a Jambu Fruit Dove Ptilinopus jambu spotted feeding with a mixed flock comprising Thick-billed Pigeon Treron curvirostra and Pink-necked Pigeon Treron vernans on 15 November 2018 at Pasir Ris Park by Alvin Seng.

Southern Singapore

The southern-most hills attracted many observers as raptors and other migrants arrived in or passed through Singapore. An uncommon Brown-backed Needletail Hirundapus giganteus was spotted on 2 November 2018 at Henderson Wave (See Toh Yew Wai), while five rare White-throated Needletail Hirundapus caudacutus were seen on 3 November 2018 at Telok Blangah Hill Park (Francis Yap).

A Greater Spotted Eagle photographed on 5 November 2018 at Henderson Wave by See Toh Yew Wai.

A Yellow-browed Warbler Phylloscopus inornatus was seen on 4 November 2018 at the same park (Daniel Ong). The next day, a Greater Spotted Eagle Clanga clanga was photographed at Henderson Wave after a rainy and slow start (See Toh Yew Wai, George Presanis and Geoff Lim). A Hodgson’s Hawk Cuckoo Hierococcyx nisicolor was spotted on 8 November 2018 at Gardens by the Bay (David Fur), while another was seen on 13 November 2018 at Jurong Island (Lim Kim Chuah). Again, on Jurong Island, an Oriental Dwarf Kingfisher Ceyx erithaca (black-backed subspecies) had the misfortune of crashing into a glass window on 22 November 2018. Fortunately, it survived and the bird was subsequently released somewhere safer by Lim Kim Chuah.

Western Singapore

Apart from the spectacular western discoveries described at the beginning of this report, this region also yielded a long list of observations. A Yellow-browed Warbler Phylloscopus inornatus was spotted on 2 November 2018 at West Coast Park (Angie Cheong, confirmed by Martin Kennewell), while the same park yielded a Great-billed Heron Ardea sumatrana on 6 November 2018 in the Marsh Garden (Zhang Licong); a female, first-for-the-season Mugimaki Flycatcher Ficedula mugimaki on 10 November 2018 (Nicholas Lim), followed by a male on 20 November 2018 (Lawrence Eu).

The Marsh Garden yielded a surprise in the form of a Great-billed Heron on 6 November 2018. Photographed by Zhang Licong.

A first-for-the-season Black Kite Milvus migrans was seen during Raptor Watch 2018 on 3 November 2018 at Tuas South (Tan Gim Cheong), as was a Malayan Night Heron Gorsachius melanolophus on 4 November 2018 at the same locality (Low Choon How). This western-most region of Singapore also yielded a rare Rosy Starling Pastor roseus on 23 November 2018 (Martin Kennewell), as well as a Japanese Paradise Flycatcher Terpsiphone atrocaudata on 24 November 2018 (Angie Cheong).

The area around Kranji Marshes, including Turut Track and Neo Tiew Lane, yielded several delights. At Turut Track on 4 November 2018, an adult male Eastern Marsh Harrier Circus spilonotus that flew high up was photographed by Low Choon How, while a Common Snipe Gallinago gallinago was spotted by Pary Sivaraman. On 5 November 2018, a juvenile Eastern Marsh Harrier Circus spilonotus was photographed at Turut Track (Francis Yap), a first-for-the-season Black Drongo Dicrurus macrocercus recorded at Kranji Marshes (Martin Kennewell) and an exhausted Cinnamon Bittern Ixobrychus cinnamomeus found along the road at Ama Keng (Low Choon How).  A Watercock Gallicrex cinerea was seen on 17 November 2018 at Harvest Lane (Khoo Mei Lin), as was a first-for-the-season Ashy Drongo Dicrurus leucophaeus on 18 November 2018 at Kranji Marshes (Andy Burns & Lim Kim Seng). Several sightings of the elusive Lanceolated Warbler Locustella lanceolata were made on 21 November 2018 at Turut Track (Lim Ser Chai) and Kranji Marshes (See Toh Yew Wai). An uncommon Sand Martin Riparia riparia was seen on 28 November 2018 at Turut Track (Fadzrun Adnan), as was a Common Kestrel Falco tinnunculus on 29 November 2018 at the nearby Neo Tiew Lane (Zacc HD).

Other records

There was a report of an immature Rufous-bellied Hawk-Eagle Lophotriorchis kienerii found by NParks on 4 November 2018 at an HDB estate (it would be interesting to examine the photo, if any, as this species is often confused with the Changeable Hawk Eagle), and a report of a Northern Boobook Ninox japonica collected on 10 November 2018 at a private residential estate (David Tan).

Singapore Bird Report – October 2018

Extinct from Singapore since the 1940s, the Large Woodshrike re-appears after 70 years. October also marks the arrival of the charismatic, migratory black-backed race of the Oriental Dwarf Kingfisher, and migrant raptors. In concert with the World Migratory Bird Day celebrated in October, we will examine the importance of Singapore as part of the East Asian-Australasian Flyway, as well as the issue of bird collisions into building structures.

Large Woodshrike : re-appears after 70 years

Extinct from Singapore since the 1940s, a Large Woodshrike Tephrodornis virgatus  made an amazing appearance at Jelutong Tower on 22 October 2018 for a few seconds, long enough for Francis Yap to capture a clear photo, before it flew and disappeared into the canopy of the trees. The lucky observers, including Oliver Tan, also noted that its loud calls in flight matched the recordings of this species.

Oriental Dwarf Kingfisher

The northern black-backed race of the Oriental Dwarf Kingfisher Ceyx erithaca started to trickle into Singapore in October. The first of the season report of the kingfisher was made on 4 October 2018 at Gardens by the Bay by Goh Bak Seng, and the bird remained there for several days, allowing many birders and photographers to view it. Another bird was spotted on Pulau Ubin on 6 October 2018 by Lim Kim Seng. On 18 October 2018, the species was reported at Satay by the Bay by Billy Tey and at Kallang Sector 2 by Richard Ngo.

The Gardens by the Bay kingfisher subsequently found itself in the local news after it was attacked by a White-breasted Waterhen while drying out on the floor of the reed bed on 6 October 2018, and was rescued by the Gardens staff and two NSS Bird Group members. The bird was subsequently released back to the Gardens by one of the Bird Group members on 7 October 2018.

Wells (1997:518-521) noted that the species migrates nocturnally, and that about 65 per cent of birds surveyed at lighthouses were first winter birds. This suggested that the Oriental Dwarf Kingfisher (black-backed race) has a relatively low rate of survival.

Central Catchment Nature Reserve

The first Red-rumped Swallow Cecropis daurica of the season was spotted at Bukit Timah on 6 October 2018 by Richard White, who also spotted a Brown-chested Jungle Flycatcher Cyornis brunneatus on Bukit Timah Hill on 15 October 2018, along with a flock of about 11 Pacific Swift Apus pacificus; another flock of about 210 birds were subsequently spotted on 22 October 2018 over Jelutong Tower by Martin Kennewell.  Six Oriental Dollarbird Eurystomus orientalis, possibly passage migrants, were seen flying high and southwards on 20 October 2018 from Bukit Timah Hill by Richard White. Another first of the season was an Indian Cuckoo Cuculus micropterus seen at Jelutong Tower on 19 October 2018 by Francis Yap, who also spotted a first-of-the-season Silver-backed Needletail Hirundapus cochinchinensis on 26 October 2018 from the same tower.

Residents spotted during October were a Buffy Fish Owl Ketupa ketupu at Singapore Quarry on 6 October 2018 by Yap Wee Jin, a flock of about 40 Plume-toed Swiftlet Collocalia esculenta from Bukit Timah Hill on 16 October 2018 by Richard White, and the rediscovery of the Large Woodshrike Tephrodornis virgatus, a former resident, as mentioned earlier.

Singapore Botanic Gardens

A solitary and skulking Brown-chested Jungle Flycatcher Cyornis brunneatus was spotted within the Evolution Garden on 28 October 2018, along with a female Common Kingfisher Alcedo atthis at Symphony Lake by Geoff Lim.

Central Singapore

A Ruddy Kingfisher Halcyon coromanda, first for the season, was spotted at Bidadari on 12 October 2018 by Kozi Ichiyama, and continued to be seen till 27 October 2018 by many observers. Also spotted on 12 October 2018 at Bidadari was a first winter Brown-chested Jungle Flycatcher Cyornis brunneatus by Art Toh and Steven Cheong; three more of the same species of Flycatcher were also seen along the former cemetery’s perimeter on 27 October 2018 by Tuck Loong and others. In addition, a Cinereous Bulbul Hemixos cinereus, a non-breeding visitor, was recorded at Bidadari on 29 October 2018 by Terry Chen.

Northern Singapore

About 1,000 Barn Swallow Hirunda rustica were reported to be roosting at the HDB estate located within Yishun Avenue 7 on 10 October 2018 by Esther Ong, while about 200-plus Grey Wagtail Motacilla cinerea, along with a White Wagtail Motacilla alba of the rare lugens subspecies and a number of Forest Wagtail Dendroanthus indicus were spotted at Yishun Street 11 on 12 October 2018 by Veronica Foo and Henrietta Woo.

Eastern Singapore

Several rare and uncommon birds were spotted on Pulau Tekong. These include an Asian Dowitcher Limnodromus semipalmatus (3 October 2018), Broad-billed Sandpiper Limicola falcinellus (6 October 2018), the rare and endangered Chinese Egret Egretta eulophotes (10 October 2018), and a single Eurasian Curlew Numenius arquata (13 October 2018), all by Frankie Cheong.

The neighbouring island of Pulau Ubin yielded several notable species as well. A good find was a Black-winged Flycatcher-Shrike Hemipus hirundinaceus photographed at Jejawi Tower on 21 October 2018 by Diane Campbell. Since the first ever record of this species in Singapore in 2013, there are less than ten records of this rare non-breeding visitor. Participants of the joint NParks-NSS surveys noted a Ferruginous Flycatcher Muscicapa ferruginea on 6 October 2018 (See Toh Yew Wai), a Little Grebe Tachybaptus ruficollis on 6 October 2018, a Grey-tailed Tattler Tringa brevipes and two Bar-tailed Godwit Limosa lapponica on 28 October 2018 (Lim Kim Keang). Other observers spotted a Gull-billed Tern Gelochelidon nilotica at Chek Jawa on 14 October 2018 (Martin Kennewell), and a resident Little Grebe Tachybaptus ruficollis at Balai Quarry on 28 October 2018 (Diane Campbell).  Two Chestnut-winged Cuckoo Clamator coromandus, the firsts for the season, were also seen at Pulau Ubin on 14 October by Pary Sivaraman and a few others.

Other birds spotted in eastern Singapore include a Black-capped Kingfisher Halcyon pileata at Pasir Ris Park on 17 October 2018 by Wang Wen; a juvenile Von Schrenck’s Bittern Ixobrychus eurhythmus rescued on the grounds of Bedok Green Primary School on 19 October 2018 by school staff and subsequently released by Isabelle Lee; a first-for-the-season flock of seven White-shouldered Starling Sturnia sinensis along Changi Coastal Road by Ramesh T.; and a Lanceolated Warbler Locustella lanceolata at Changi Point Ferry Terminal on 30 October 2018 by Lim Kim Seng.

Southern Singapore

A rare Blue Rock Thrush Monticola solitarius was spotted on 2 October 2018 at the Labrador Power Station by Art Toh, while two Daurian Starlings Agrospar sturninus were seen at Satay-by-the-Bay on 28 October 2018, and a Kentish Plover Charadrius alexandrinus at the nearby Marina Barrage on 31 October 2018 by Martin Kennewell.

The southern ridges also yielded a rare Asian House Martin Delichon dasypus on 20 & 21 October 2018 (Adrian Silas Tay & See Toh Yew Wai, respectively), 23 Oriental Pratincole Glareola maldivarum on 21 October 2018 by Low Choon How, and up to five White-throated Needletail Hirundapus caudacutus on 28 October 2018 by Daniel Ong and Martin Kennewell.

A notable resident species spotted in the south was the House Swift Apus nipalensis at Kent Ridge Park and Henderson Wave on 20 October 2018 by Alan Owyong and Zacc HD, respectively.

Western Singapore

SBWR remains an important bird area in Western Singapore, attracting and holding residents and migrants alike. Notable migrants include two Long-toed Stint Calidris submimuta on 8 October 2018 by Stuart Campbell, a first-of-the-season Brown-chested Jungle Flycatcher Cyornis brunneatus on 9 October 2018 by Subha & Raghav, another first-of-the-season Black-capped Kingfisher Halcyon pileata by Feroz also on 9 October 2018, and a Bar-tailed Godwit Limosa lapponica on 16 October 2018 by Stuart Campbell. Notable residents/NBV include the Abbott’s Babbler Malacocinla abbotii and Lesser Adjutant Leptoptilos javanicus, spotted on 2 October 2018 by Lawrence Eu.

Other birds spotted in the west include White Wagtail Motacilla alba on 14 October 2018 by Felix Wong, Grey Wagtail Motacilla cinerea on 18 October 2018 by Art Toh, more than 300 roosting Blue-throated Bee-eater Merops viridis at Eng Kong Terrace on 21 October 2018 by Richard White, a juvenile Hodgson’s Hawk Cuckoo Hierococcyx nisicolor on 22 October 2018 by Amin (Last Romeo) at West Coast Park, and a flock of first-of-the-season Ashy Minivet Pericrocotus divaricatus seven strong at Nanyang Technological University (NTU) grounds on 31 October 2018 by James Lambert.

Bird Collisions into Buildings

The migratory Blue-winged Pitta Pitta moluccensis is a much sought after species by birders and photographers alike because of its strikingly beautiful plumage. Normally residing in wooded areas, the species could be found all over the country at the start of the migration season. It was unfortunate that the pitta, along with the Oriental Dwarf Kingfisher, attracted considerable attention in social media, as it is one of four ‘super colliders’, a term used for species whose fatalities exceeded 20 specimens collected during a period of study by Low, Yong, Tan, OwYong and Chia (2017) on migratory bird collisions in Singapore.

This season, one pitta was reported to have crashed but survived at Jurong West on 3 October 2018, by Serena Chew. Three others were not so fortunate on 13 October 2018. They were found dead at Bedok, Tampines and Joo Chiat, and collected by David Tan.

Other collisions include a female Siberian Blue Robin Larvivora cyane, which survived a collision at MacPherson on 25 October 2018, reported by Peng Ah Huay; an Eastern Crowned Warbler Phylloscopus coronatus which survived a collision at Chinatown on 29 October 2018, reported by Kenneth Koh and a Pallas’ Grasshopper Warbler Locustella certhiola, which survived a collision on 29 October 2018 on Jurong Island, reported by Lim Kim Chuah.

Raptors

The month yielded a Crested Serpent Eagle Spilornis cheela on 16 October 2018 at Kent Ridge Park, by Veronica Foo, and the second half saw the onset of migratory raptors drifting into Singapore. Raptor watchers keeping vigil at Henderson Wave spotted Grey-faced Buzzard Butastur indicus on 21 October 2018 (2 birds), 26 October 2018 (2 birds) and 27 October 2018 (2 bird) by See Toh Yew Wai & friends, Sandra Chia & Oliver Tan, and Francis Yap, respectively. A first-for-the-season Black Baza Aviceda leuphotes was spotted on 22 October 2018 by Zacc HD, while a kettle of 29 birds were spotted from Hindhede Nature Park on 29 October 2018 by Richard White. Other raptors included a first-for-the-season Greater Spotted Eagle Clanga clanga at Henderson Wave on 27 October 2018 by Alan Owyong, and a first-for-the-season Rufous-bellied Eagle Lophotriorchis kienerii at Pang Sua Connector on 30 October 2018 photographed by Fadzrun Adnan, identified by James Eaton. For a more detailed report on raptors, please refer to the NSS Bird Group’s latest raptor report.

Photo by Geoff Lim.

The World Migratory Bird Day (WMBD) was initiated in 2006. Originally held once a year, the campaign is now held twice a year, on the second Saturday of May and October. The WMBD was celebrated at Sungei Buloh Wetland Reserve on Saturday, 13 October 2018, with the participation of NSS Bird Group. There were daily programs during the week leading up to WMBD.

The East Asian Australasian Flyway (EAAF) is one of the world’s major flyways. Spanning 37 countries from Far Eastern Russia, China, Korea, Japan, South-east Asia and the western Pacific, used by about 50 million migratory waterbirds, and countless land bird species comprising 492 species (Birdlife, 2018). Singapore is used as a stopover for many species of land and water birds.

On 7 October 2018, which was the 25^th anniversary of SBWR, NParks made an important announcement that the Mandai mangrove and mudflats would be conserved as a nature park as research has shown that shorebirds feed at these habitats during low tide, and return to roost at SBWR when the tides come in. The area will open as a nature park in 2022. You can read more about how these habitats were saved through the contribution of ordinary volunteers, in partnership with government authorities here.

Pelagic Trip along Straits of Singapore

A pelagic trip organised by Martin Kennewell and friends on 13 Ocotber 2018 yielded a Common Tern Sterna hirundo and a Parasitic Jaeger Stercorarius parasiticus. Note that these may not have been in Singapore waters.

 

This report is compiled by Geoff Lim and Alan OwYong, and edited by Tan Gim Cheong based on selected postings in various facebook birding pages, bird forums, individual reports and extracts from ebird. This compilation is not a complete list of birds recorded for the month and not all the records were verified. We wish to thank all the contributors for their records. Many thanks to Francis Yap, Angela Yeo, Geoff Lim, Steven Cheong, Terry Chen, Frankie Cheong, Terence Tan, Danny Khoo, Stuart Campbell, Pary Sivaraman, David Tan, Zacc HD, and Fadzrun Adnan for the use of their photos.

Singapore Raptor Report – October 2018

Chinese Sparrowhawk, female, at Henderson Waves, 24 Oct 2018, by Francis Yap. Two generations of feathers can be seen, the older (brownish) and the newer (grey) feathers.

Summary for migrant species:

October 2018 is probably the most remarkable October on record, with 11 migrant species recorded. This is in stark contrast to last October when only 6 migrant species were recorded (we usually record around 9 species in October). A big thank you to the burgeoning number of raptor watchers, especially at Henderson Waves.

Chinese Sparrowhawk, female, at Henderson Waves, 21 Oct 2018, by Pary Sivaraman.

453  migrant raptors were recorded, many times the 70 recorded last year. The most numerous were the 219 Oriental Honey Buzzards, followed by 123 Japanese Sparrowhawks, and 57 Chinese Sparrowhawks. In addition, more than 100 unidentified Accipiters were spotted this month and these were likely to have been either Chinese or Japanese Sparrowhawks. The first of the 35 Black Bazas appeared on 22 Oct, more than a week earlier than last year.

Birders at Henderson Waves were rewarded with three sought-after species. The first was the appearance of two Grey-faced Buzzards on 21 Oct, followed by a juvenile Eastern Marsh Harrier on the same morning. Another four Grey-faced Buzzards were spotted over Henderson Waves days later: two on 26 Oct and two on 27 Oct, around mid-day on both dates. In addition, birders on 27 Oct also spotted a Common Buzzard Buteo buteo before noon (note: the various subspecies are ‘lumped’ as Buteo buteo in the NSS bird checklist).

Later the same day, 27 Oct, around noontime, a rare Greater Spotted Eagle made an appearance at Kent Ridge Park, delighting Alan OwYong. Before the month ended, Fadzrun Adnan photographed an immature Rufous-bellied Eagle, another rare visitor, at Pang Sua park connector on 30 Oct, flying about in the company of an Oriental Honey Buzzard.

Two Western Ospreys were recorded, one at the Kranji-Sungei Buloh area and one at Henderson Waves. Six migrant Peregrine Falcons were recorded.

Highlights for sedentary species:

October was a good month for the locally rare Crested Serpent Eagle, with records from four different areas, from Nanyang Technological University (west) on 8th, Pulau Tekong (offshore) on 8th, Jelutong Tower (centre) on 24th and the Southern Ridges (south) on 16th, 21st & 30th.

On 6 Oct, a pair of Crested Goshawks were observed mating at West Coast Park. Then on 23 Oct, 2 chicks of the White-bellied Sea Eagle were seen on a nest at Woodlands. These  are good signs for our resident raptors.

On 6 Oct, at Pulau Ubin near the main jetty, a juvenile Peregrine Falcon of the resident ernesti subspecies was photographed. This form bears some resemblance to, and may be mistaken for, the Oriental Hobby. The other resident raptors recorded included the Grey-headed Fish Eagle, Black-winged Kite, Brahminy Kite and Changeable Hawk-Eagle.

34th Singapore Bird Race (2018) – Arbitrator’s Report

The 34th Singapore Bird Race, held on 11 November 2018, saw the participation of 31 teams across three categories, including the first ever ‘School’ category. Some of the participants also took part in the inaugural Best Picture Contest.

Category	Number of Teams
School	9
Photographer	10
Birder	12

School Category – Top 3 Teams

For this category, the enthusiastic students lead by volunteer guides, scoured the Sungei Buloh Wetland Reserve, recording good numbers of species, most of which were ‘lifers’ (first time seeing a species of bird) for the students.

There were four primary school teams, two each from Shuqun Primary and Yumin Primary. The Eagles (Shuqun Primary) led the pack with 32 species. Team Champs A (Yumin Primary) was a very close second with 31 species, just 1 species behind. And the Vultures (Shuqun Primary) took the third place with 24 species.

For secondary schools, there were four teams from Unity Secondary and one team from Chung Cheng High (Main). Again,  it was a close fight between the top two places. Unity 1 came in tops with 36 species, closely followed by Team Cool & Mysterious (Unity Secondary) with 35 species.  Team CCHM came in third with 32 species. As it turned out, there were winning teams from all the schools, congrats.

Photography Category – Top 3 Teams

Ten teams took part in this category. Team In the Tree (Goh Cheng Teng & Lester Tan) topped the Photography category with 55 species caught on camera, successfully defending their title from last year. Team Alpha Dynamo (Kwok Tuck Loong & Tay Sia Ping) came in 2nd with 45 species. Right behind them was Wings of Johor (Belinda Wong & Chiang Lai Peng) with 44 species, another close fight! Great work.

Birder Category – Top 3 Teams

To minimise time spent travelling, most of the birder teams limited themselves to the Kranji-Sungei  Buloh areas. The Terns (Lim Kim Keang, Alfred Chia & Tan Ju Lin) turned in an amazing 78 species to clinch the top prize, successfully defending their title. Hot on their heels were the Drongoes (Danny Lau, Lau Jiasheng & Ang Bao Jun) who managed 77 species, just 1 species behind – another close fight. The Falconets (Benjamin Lee, Max Khoo & Bryan Lee) finished 3rd with 73 species. Well done.
