Singapore Bird Report – October 2017

22179889_1472239912896645_8256191510998948950_oThe avian phenomenon at Yishun. Hundreds of Grey Wagtails roosting with Forest Wagtails. 

The avian phenomenon of the year had to be the congregation of wagtails at Yishun and Sembawang. On 23rd of September Shahrulbariah Arif-Sng alerted us to large flocks wagtails roosting on the palm trees at Yishun St 11 on Bird Sightings FB page. They were identified as Grey Wagtails Motacilla cinerea. Counts in early October exceeded 200. In the past we normally get to see one or two Grey Wagtails foraging at some quiet monsoon drains in the west. This large gathering has never happened here before. Another surprise was finding a small number of White Wagtails Motacilla alba and Forest Wagtails Dendronanthus indicus roosting with them. Alfred Chia managed to identify a rare lugens sub-species among the White Wagtails from photos posted. The Forest Wagtails forage at a different habitat from the other two, so how and why did they come to know about this roost was another mystery. On the 9th, Esther Ong reported another congregation of Grey Wagtails, this time at Sembawang a few kilometers away. The numbers here were just as impressive as those in Yishun. Efforts to find them in the day were not successful. We can only guess that they may be feeding somewhere in Johor. Another mystery was the absence of the Yellow Wagtails at both roosts.

On 14th, Mike Smith made avian history when he chanced upon a nest of the Red-legged Crake Rallina fasciata with a clutch of 5 eggs, at the Singapore Botanic Gardens. He monitored the nesting and found that some of the chicks hatched on 3rd and 4th Nov. This will be the first documented nesting of this uncommon and elusive crake in Singapore.

Francis Yap’s photo of the year, a very rare vagrant, the White-throated Needletail flashing by over CCNR on 25th. 

The other excitement for the month were the sightings of the White-throated Needletail Hirundapus caudacutus a very rare vagrant first photographed over Bukit Timah Hill on 5 April 2008. There have been no records since then yet there are 3 records this month alone! Keita Sin managed to photographed one flying over Henderson Wave on 19th and another on 31st. In between Francis Yap posted an excellent photo of one he shot flying over Jelutong Tower on 25th. As a bonus, Keita also shot a very rare migrant, the Asian House Martin Delichon dasypus over Henderson Wave on 19th with Francis Yap following up with another over Jelutong Towers on 20th. Well done guys!

This October, we welcomed back the Blue-winged Pittas Pitta moluccensis, the Brown-chested Jungle Flycatchers Cyornis brunneatus and the Siberian Blue Robins Larvivora cyane and other passerines to our forests and parklands. Bidadari is still a desirable stopover for many of our winter visitors, with the arrival of two Brown-chested Jungle Flycatchers on 5th (TT Koh). Laurence Eu had one at Labrador NR on the 24th and another seen at Rifle Range Link the next day by Francis Yap and Richard White. Con Foley had another late arrival at Bidadari on 27th. Other records came from Jurong Central and Chinese Garden, Singapore Zoo and Botanic Garden. Singapore is the best place to see this globally threatened species in the winter.

As for the Blue-winged Pitta, the first one was picked up at Jurong Island although one was heard calling on the 10th at the Bulim Forest last month. Lim Kim Chuah found it on the floor of his office building on 22nd. He managed to nurse it back for release a few days later. The one found by Jayon P. Thomas at IMH on 23rd and another by Art Toh at Labrador old flats on 27th  were not so fortunate. But it was the one that ‘got lost’ and ended up at the playground at Hougang Central on 27th that became the star attraction of the month. Another one was reported at Potong Pasir by Choon Beng on 30th.

Lim Kim Chuah also found two Siberian Blue Robins, one a young male on the 22nd and the other on 23rd at his Jurong Island office. Both died as a result of window collision. Earlier on the 17th, David Tan retrieved the carcass of another dead Siberian Blue Robin from Bishan. It was killed by a cat after surviving a building collision there. Richard White reported a female at Hindhede NP on 21st.

We also had three “out of range” sightings this month. A Verditer Flycatcher Eumyias thalassini  was photographed by George Presanis at DFNP on 9th. Another species, the montane Little Pied Flycatcher Ficedula westermanni was reported by Dr. Niel Bruce at the downtown old Muslim Cemetery on 15th. Martin Kennewell and a few birders were at Hindhede NP looking for the Oriental Dwarf Kingfisher when they saw a Great Hornbill Buceros bicornis flying across the park. All these were not seen again. The Records Committee will be reviewing these records for their status.

Francis Yap

A Crow-billed Drongo Dicrurus annectans was photographed by Francis Yap at Windsor Park on 2nd. He later reported another on 25th at Rifle Range Link. A Black Drongo Dicrurus macrocercus was photographed by Hung Ting Wei off SBWR perched on the nettings. Pacific Swifts Apus pacificus were seen all over the Southern Ridges this month.  Zacc HD had one over KRP on 3rd and Alan OwYong came in with a report of five on 19th there. Red-rumped Swallows Cecropis daurica were flying around the Kranji Marshes on 7th (Annual Bird Race) and photographed perched at Turuk Track on 28th by Fadzrun Adnan.  The first Chestnut-winged Cuckoo Clamator coromandus  was reported by Goh Juan Hui at SBWR and as expected very skittish. Another early cuckoo, the Indian Cuckoo Cuculus micropterus was reported on ebird by Martin Kennewell. It was seen at Bidadari on 17th. A third cuckoo, the Drongo Cuckoo Surniculus lugubris was reported by Seng Beng on 29th at the SBTB. Martin Kennewell picked up a first White-shouldered Starling Sturnia sinensis over at Pulau Ubin on 8th.

The first Oriental Dwarf Kingfisher Ceyx erithaca made a one day stop over at Hindhede NP on the 9th (Siew Mun and Francis Yap) much to the dismay of many birders and photographers. But the Ruddy Kingfisher Halcyon coromanda did not make it. David Tan showed us the carcass after it collided with a building at NUS on 16th. The wait for the Black-capped Kingfisher Halcyon pileata ended with a sighing at Marina Barrage on 20th by Zan J. The regular at the Kranji Marshes was reported by Francis Yap four days later. It was still around on 29th during the NSS Bird Walk. A Malaysian Hawk-Cuckoo Hierococcyx fugax was seen briefly at DFNP on the 10th by Alan OwYong and See Toh Yew Wai. Lee Van Hien had another at Bidadari on 25th. This non-breeding hawk-cuckoo always precedes the migratory Hodgson’s.

Ferruginous Flycatcher “Iron Boy” from Pulau Ubin on 22nd by Veronica Foo.

A dead Pallas’s Grasshopper Warbler Locustella certhiola was picked up at Changi T4 by Willie Foo on 10th. Another was reported at Kranji Marshes on 24th by Francis Yap. The rarer Lanceolated Warbler Locustella lanceolata was found by James Lambo on 29th at Tuas South. The first Ferruginous Flycatcher Muscicapa ferruginea was reported by Avinash Sharma at MacRitchie Park on 15th. Veronica Foo had a juvenile at Pulau Ubin on 22nd while conducting the Fall Migration Bird Census. An unconfirmed record came from Bidadari during the last week of the month.

A very fortunate Laurence Eu was at the right place and time to snap this rare passage migrant, a Japanese Paradise Flycatcher, at Labrador Nature Reserve on 24th.

The rare Japanese Paradise Flycatcher Terpsiphone atrocaudata made a one day stop over at the Labrador NR on 24th. Laurence Eu was at the right place and time to captured it on his camera’s sensor. Last year he also found the one at the Zoo on 31st October. We ended the month with an Ashy Minivet Pericrocotus divaricatus at Kranji Marshes (Veronica Foo) and a spectacular flypast of 66 Oriental Pratincoles Glareola maldivarum across Jelutong Tower was captured by Goh Cheng Teng. One was reported by Martin Kennewell earlier on 22nd at the Kranji Marshes.

 

Sanderling Luke

A lone Sanderling turned up at the Marina Barrage on 14th. Luke Milo Teo was there to snap it up. Another new species to add to this city waterfront.

The breakwaters next to Marina Barrage continue to attract interesting shorebirds like the juvenile Sanderling Calidris alba on 12th (Luke Milo Teo). This was where a Little Ringed Plover Charadrius dubius was reported two days earlier by TT Koh. The number of Red-necked Stints Calidris ruficollis at Marina Barrage went up to four on 17th (Alan OwYong).

A rather greyish Long-toed Stint Calidris subminuta and Wood Sandpipers Tringa glareola were at Frankie Cheong’s restricted site at Pulau Tekong on 21st. Two more Wood Sandpipers were seen at the Kranji Marshes together with a Common Snipe Gallinago gallinago on 29th during a Bird Group walk (Lee Ee Ling/ Yap Wee Jin). These fresh water shorebirds are the one that Nparks wants to bring in to the marshes.

Larger waterbirds sighted include a Black-tailed Godwit Limosa limosa and Chinese Egret Egretta eulophotes at Pulau Tekong on 9th and 10th (Frankie Cheong), a Pacific Reef Egret Egretta sacra showing up at Marina Barrage on 16th (Siew Mun), a Black Bittern Dupetor flavicollis found dead at Jurong West on 23th by Ben Choo and another, very much alive was photographed at SBTB on 27th by Robin Tan.

Notable residents reported this month were the rare Lesser Green Leafbird Chloropsis cyanopogon at BTNR by James Lambert on 15th. A sizable flock of 10 Green Imperial Pigeons Ducula aenea present at PRP on the 9th (Seng Alvin), up to 20 House Swifts Apus nipalensis over at KRP out hawking for insects in the evening of the 19th (Alan OwYong) and a large flock of 26 Lesser Whistling Ducks Dendrocygna javanica being flushed out at Kranji Marshes on 22nd (Martin Kennewell). Good to see that they are returning to Kranji Marshes. Both the House Swift’s and Whistling Ducks numbers were the highest for some  time.

Francis Yap and company organised the only pelagic in the Singapore Strait (a multi-national stretch of water) for the month on 14th and returned with a Parasitic Jaeger, Stercorarius parasiticus, a few Aleutian Onychoprion aleuticus and Bridled Terns Onychoprion anaethetus among others.

Out of Season Breeding of the Malaysian Plovers in Singapore.

By Goh Cheng Teng.
Introduction:
The Malaysian Plover is an uncommon resident shorebird found around the coastal sandy area of mainland Singapore and Pulua Semakau. First recorded in 12 October
1963 at Jurong by JC Darnell and MA Webster,  where subsequent sightings were also seen. They have been since recorded at Changi Coast, Tuas and Semakau.  One or two pairs have also been reported in Pulau Tekong, Seletar Dam, Marina East and Labrador as well.  It is considered nationally threatened ( Lim K S 1992) and globally near threatened.
On 17 September 2017, Lester Tan and I were scouring the shoreline of Marina East in search of the Red-necked Stint Calidris ruficollis, that had been reported earlier in the week when we came across a Malaysian Plover Charadrius peronil chick following its parents around. As we approached closer, the chick laid still as it attempted to camouflage itself among the debris and uneven surface of the seawall.

After a brief period of close up observation, we retreated to allow the parents to collect the chick, which they did after we were a distance away.

The following weekend, on 23 September, we returned to the same section of the seawall in hopes of seeing the progress of the chick. We were not disappointed.

23rd September 2017. Marina East. Glad to see it is still around.
The next day on 24th, the chick was again sighted. On this occasion, the family was observed venturing to the top of the seawall as well.

Unfortunately, we were unable to return to Marina East in the subsequent weeks to further observe the chick’s progress. This series of sightings, however brief, has been a treat for us, and we hope the chick survived to adulthood successfully.
Addendum:
According to the Avifauna of Singapore (Lim Kim Seng 2009),  breeding had been reported in March and April and its breeding season remains to be investigated.
This record is probably the first of a pair breeding in September although I
have previously observed 2 nesting of Malaysian Plovers in Tuas South in July and August. We hope that this record will add to our knowledge of the breeding cycle of our only resident shorebird and help with their protection.

Nesting and Breeding Record of Stork-billed Kingfisher in Singapore

NESTING AND BREEDING RECORD OF STORK-BILLED KINGFISHER IN SINGAPORE

By Lim Kim Chuah and Marcel Finlay

The Stork-billed Kingfisher is the largest of the 8 species of kingfishers known to occur in Singapore. It has a wide distribution and can be found from the Indian subcontinent, mainland Southeast Asia to Singapore and east to the Philippines and Sulawesi. In Singapore, it is an uncommon resident and can typically be found in the mangroves, forest edges around our reservoirs and water areas. Some of the places include Sungei Buloh Wetland Reserve, Kranji Marsh, Singapore Botanic Gardens, Pasir Ris Nature Park, Bukit Batok Nature Park, Hindhede Nature Park, MacRitchie Reservoir and Pulau Ubin.

Like many of our resident birds, there is not much documentation on the nesting or breeding of this species. Lim KS1 mentioned that breeding has been reported but nest has not been found in Singapore.

On 4 June 2017, I was scanning around the Pekan Quarry, Pulau Ubin when I noted a pair of Stork-billed Kingfisher at the far end of the quarry. The pair was observed entering into a termitarium nest. The termitarium was appended on bamboo plants growing at the edge of the quarry pond.  During my brief period of observation, the kingfishers were observed to fly into the hole periodically. Often one bird could be seen to perch nearby while the other is in the hole. This behaviour suggest that the birds were possibly nesting in the termitarium.

1-SBK_5L5A6898 crop-001

Cropped picture showing the kingfisher perched (top left) close to the termitarium

According to Wells2, Stork-billed Kingfishers have been observed to use both soil and arboreal termitarium as nesting places. This observation of the Stork-billed Kingfisher using an arboreal termitarium at Pekan Quarry is probably the first documented record of the nest of the Stork-billed Kingfisher in Singapore.

To add to our breeding record of this species, Marcel Finlay observed an individual at the Petai Trail, MacRitchie Reservoir in 4 July 2017. The bill of this individual was mostly black and the legs were not the usual bright red. These features are indicative of a juvenile bird which is not often reported in Singapore.

I hope this short note will add to our knowledge of breeding birds in Singapore.

Singapore Bird Report-September 2017

The autumn migration is truly underway this month with more passerines reported all over the island. Out of the twenty plus arrivals this month, only four beat their previous early arrival dates. Some like the Arctic Warblers were very late. 

The list of the first arrivals of the season:

Adrian Silas Tay

  1. Ruddy Turnstone Arenaria interpres, six birds scoped at Pulau Sekudu, Ubin on 1st by Lim Kim Keang, Low Choon How and Russell Boyman
  2. Greater Sand Plover Charadrius leschenaultii at Marina Barrage on 1st by Russell Boyman. Photo posted by Seng Alvin on 2nd. Another reported at Seletar Dam on 7th by Fadzrun A.
  3. Red-footed Booby Sula sula, a dried up carcass was found washed up on the seawall at Marina Barrage on 3rd by Adrian Silas Tay and friends. May have died at sea while on transit.
  4. Green-backed Flycatcher Ficedula elisae, a female at Dempsey Hill on 7th photographed by Lawrence Eu. This is 10 days earlier than the previous early arrival date.
  5. Daurian Starling Agropsar sturninus a small flock seen at the sand banks at Seletar Dam on 7th by Wang Heng Mount.
  6. Asian Dowitcher Limnodromus semipalmatus, with a Godwit at Pulau Tekong on 9th by Frankie Cheong.
  7. Chinese Egret Egretta eulophotes, bird seen on the same day on Tekong by Frankie Cheong. Another three were reported there on 23rd and one on 29th. The reclaimed land there had been their favourite wintering ground for the past few years.
  8. A White-winged Tern Chlidonias leucopterus was reported by Adrian Silas Tay at Lorong Halus on 10th. Lim Kim Keang reported several White-winged Terns feeding at Serangoon Reservoir on 15th. White-winged Terns usually arrives much earlier in July and August.
  9. Adrian Silas Tay also had a Whiskered Tern Chlidonias hydrida, at the  Lorong Halus that same day. This is about a week later than last year’s early date.
  10. Blue-winged Pitta Pitta moluccensis, one heard calling at the Bulim Woods on 10th by James Tann. It could be either an overstayer or a new arrival.
  11. Forest Wagtail Dendronanthus indicus, seen at the MacRitchie Trail on 10th by Marcel Finlay. This was followed by one at GBTB on 25th photographed by Terence Tan and another at DFNP by James Tann on 25th.
  12. Another Wagtail, this time an Eastern Yellow Wagtail Motacilla  tschuschensis, from Kranji Sanctuary Golf Course on 10th by Fadzrun A.
  13. Martin Kennewell had an early Pin-tailed Snipe Gallinago stenura, at Kranji Marshes on the 10th. Identified by call, this individual is 5 days earlier than the previous arrival date.
  14. Red-necked Stint Calidris ruficollis first one reported at Seletar Dam on 8th by Marcel Finlay. The second, a juvenile made a late landfall at Marina Barrage on 13th, duly spotted by Robin Tan. This juvenile stayed over to refuel for more than 2 weeks. On 23rd, Frankie Cheong reported three more Red-necked Stints at Pulau Tekong.
  15. Kentish Plover Charadrius alexandrinus, two birds were photographed at the Marina Barrage on 15th by Robin Tan. Pary Sivaraman posted another photo of one of them he shot the next day. A subspecies, the Swinhoe’s Plover C.a. dealbatus, was identified by Dave Bakewell from photos taken there by Alan OwYong on the 15th.
  16. Amur Paradise Flycatcher Terpsiphone incei, a recent split, was photographed at Chinese Gardens on 20th by Siew Mun and seen by Marcel Finlay at Bukit Brown on same day. He had another at Old Thompson Road on 25th. Terence Tan also shot one at DFNP on 21st. Two birds were reported from Bidadari as well on 24th by Francis Yap and Alan OwYong. The Amur seems to be more commonly encountered than the Blyth’s during this migratory period. 
  17. Drongo Cuckoo Surniculus lugubris, was photographed at the Japanese Gardens on 21st by Gerald Lim.
  18. A returning non-breeding visitor, Blue-tailed Bee-eater Merops philippinus, was photographed at Lorong Halus on 26th by Seng Alvin. This is just a day earlier than the last reported date. Alan OwYong saw the same bee-eater there the next day.
  19. Blue Rock Thrush Monticola solitarius, a male was a surprise find at Gardens East on 27th. It beats the earlier arrival date by 3 weeks. Unfortunately it did not stay around.
  20. Over at Pulau Ubin, a confiding Oriental Dwarf Kingfisher Ceyx erithaca, was spotted by See Toh Yew Wai, Francis Yap and friends on 23rd. Last year one crashed into the River Valley High School on the same day.
  21. A Brown Shrike Lanius cristatus, was first recorded at Bukit Brown on 20th b=y Marcel Finlay. A second arrived at Bidadari on 24th. Robin Tan was there to welcome it. The next day another was picked up by Terence Tan at GBTB.
  22. Pallas’s Grasshopper Warblers Locustella certhiola, are overdue. Great that Rama Krishnan heard one calling at the Kranji Marshes on 25th to confirm that they arrived. These confiding warblers are notoriously hard to see.
  23. Two Arctic Warblers Phylloscopus borealis, was reported by Tay Kian Guan on 21st at the Southern Ridges. Veronica Foo saw another at Hindhede NP on 28th. Unusually late as we get them in early August.
  24. Finally we had our first Brown-chested Jungle Flycatcher Cyornis brunneata, when Martin Kennewell photographed one at SBWR on the 30th. Previous early arrival date was 23rd September.
  25. Kozi Ichiyama recorded the first Yellow-rumped Flycatcher Ficedula zanthopygia, on the last day of August. It was the start of an influx of these flycatchers all over the island for the whole of September including our second casualty that crashed into a factory in the Joo Koon, Tuas area on 18th (David Tan).

        (Note: Please notify alan.owyong@gmail.com if you had an earlier sighting of any of the above or unreported species)

Based on our previous pelagic trips, mid September was the height of the passage of the Swinhoe’s Storm Petrels Oceanadroma monorhis, and Bridled Terns Onychoprion anaethetus, with counts of 5-600 birds. Unfortunately the 17th September trip organised by the Bird Group for NSS members came back with very low counts for both (16 for Bridled and 18 for the Storm Petrels). But they did established new early arrival date for the 25 Aleutian Terns Onychoprion aleuticus. Other seabirds recorded by Alfred Chia, Lim Kim Keang, Lim Kin Seng, Con Foley and others were 25 Swift Terns Thalasseus bergii, 3 Lesser Crested Terns Thalasseus bengalensis, and 1 White-winged Tern.

Alfred Chia, Lim Kim Keang and Veronica Foo did a quick shorebird count at Chek Jawa on 24th. Their tally included 200 Lesser Sand Plovers Charadrius mongolus, 9 Terek Sandpipers Xenus cinerea , 7 Barred-tailed Godwits Limosa lapponica, 15 Whimbrels Numenius phaeopus, 35 Grey Plovers Pluvialis squatarola, 25 Little Terns Sternula albifrons, 3 Pacific Golden Plovers Pluvialis fulva, 2 Great-billed Herons Ardea sumatrana and 2 Common Sandpipers Actitis hypoleucos.

Mangrove Whistler caught the eyes of James Tann at Pulau Ubin. 

With more birders and photographers in the field it was not surprising that a good number of rare and uncommon resident species were reported, most of them from Pulau Ubin. The elusive Mangrove Blue Flycatcher Cyornis rufigastra, was heard calling along the Chek Jawa boardwalk at Pulau Ubin on 1st by Low Choon How and heard again by Veronica Foo on 3rd. Staying at Ubin, Veronica added 3 Black-crested Bulbuls Pycnonotus flaviventris, from Butterfly Hill on the 15th, an unusual record for Ubin. A day later James Tann returned with great photos of the Mangrove Whistler Pachycephala cinerea, a much sought-after island species. There were two birds at Ketam according to Adrian Silas Tay.

The NParks survey team and volunteers did one better when they found a juvenile Barred Eagle Owl Bubo sumatranus, among the durian trees on the 18th. Subsequent visits confirmed the presence of its parents nearby although out of sight. This is the first evidence of the presence of a breeding family of this rare owl in Singapore.

Veronica Foo

The female Black Hornbill Anthracoceros malayanus, made an appearance on 21st (Alan OwYong) feeding together with the Oriental Pieds at Butterfly Hill. During the hunt for the owl, See Toh Yew Wai, Francis Yap and friends spotted a Ruddy Kingfisher Halcyon coromanda, there on 23rd. This could be our resident minor race or a migrant. The previous earliest arrival date of the migratory Ruddy Kingfisher was also on the 23rd at Pasir Ris Mangroves in 1989. The last uncommon record for Ubin were 2 Cinereous Bulbuls Hemixos cinereus, a non-breeding visitor, seen by Lim Kim Keang, Alfred Chia and Veronica Foo on 24th.

Other notable residents was a King Quail Excalfactoria chinensis, from Kranji Marshes on 10th by Martin Kennewell, 14 Lesser Whistling Ducks Dendrocygna javanica, at Lorong Halus pond on 15th by Lim Kim Keang, 3 White-rumped Munias Lonchura striata, at Sentosa Cove on 18th by Lim Kim Seng. A high count of 6 Red-legged Crakes were seen and heard calling at Bukit Brown on 19th and 20th by Marcel Finlay. An Eastern Barn Owl Tyto delicatula, at Buloh Crescent on 29th by Derrick Wong, 4 Lesser Adjutants Leptoptilos javanicus, seen flying from Kranji Marshes Tower on 30th by Martin Kennewell and a Yellow-crested Cockatoo Cacatua sulphurea, at Sentosa on 30th by Lim Kim Seng. The White-rumped Munia is a new record for Sentosa but it’s status will required verification. The sighting of the 4 Lesser Adjutants was the largest for this former resident so far in Singapore. Lets hope they will re-establish here again.

Singapore Bird Report – August 2017

Eurasian Curlew, 29-8-17, SBWR Hide 1D, STYW

Eurasian Curlew, at SBWR on 29 Aug, by See Toh Yew Wai

Pulau Ubin Commonest Birds Quest 2017

Pulau Ubin Commonest Birds Quest (CBQ) 2017

By Lim Kim Keang

INTRODUCTION

On 11 June 2017, the Nature Society (Singapore) Bird Group conducted the second survey to find out which were the commonest bird species on Pulau Ubin. This survey was organized in conjunction with Pesta Ubin which covered a 3-month period from May to July 2017.

METHOD

A total of 10 teams consisting of 10 leaders and 28 participants took part in this year’s CBQ. Areas in the west, central and eastern part of Pulau Ubin were covered. The routes included those in 2016 with additional routes to cover as much of the island as possible within the allocated time from 8.00 to 10.30 am. The good weather helped and all the teams completed their designated route in the allocated time.

The same MacKinnon bird listing method used in 2016 was again used this year. This method involved recording each new species of birds (seen or heard) until a pre-defined number of species is reached. Once this pre-defined number is reached, a new list is started. Any one species will only be recorded once in the first list but may be recorded again in subsequent lists. For our purpose, we continued to use a list of 10 species before starting on a new list.

The relative abundance of each species is calculated by dividing the number of contacts by the total number of contacts by all teams. A contact is defined as a list of 10 birds. For example, the number of contacts for Common Iora was 31. There was a total of 54.4 contacts by all team. The relative abundance of Common Iora is calculated by dividing 31 by 54.4 which equals 0.57. A bird which is more common will have a higher relative abundance index than one which is less common.

RESULTS & DISCUSSION

Table 1 shows the top 20 commonest birds based on the relative abundance indices.

10 Pink-necked Green Pigeon 17 0.31 20 House Crow 10 0.18
21 Common Emerald Dove 10 0.18

The survey by the 10 teams produced a total of 54.4 lists. The relative abundance index of the birds detected ranged from 0.02 to 0.57. A total of 60 species were recorded during the CBQ. The most abundant species are Common Iora, White-rumped Shama and swiftlets (not identifiable to species). These three species registered the highest relative abundance index of 0.57 and were recorded in 100, 90 and 80 percent of the surveyed sites respectively. Both the iora and shama are very vocal at this time of the year and are easier to detect. This could be a contributing factor for their high score. Swiftlets are likely to be Germain’s or Black-nested Swiftlet but could also be hybrid species from the swiftlet farms in Johor. As noted in CBQ 2016, other censuses conducted by the Bird Group have consistently found the Yellow-vented Bulbul to be a very common bird in most parts of Singapore.

OLYMPUS DIGITAL CAMERA

The Common Iora is one of the three most common bird counted in 2017 with 31 contacts.

Last year’s most common bird the Olive-winged Bulbul is sixth this year. The Yellow-vented and Straw-headed Bulbuls are fourth and fifth respectively on the CBQ 2017 list. The habitat on Pulau Ubin which consists of a mosaic of orchards, old rubber plantations and secondary forest are good for omnivorous birds like bulbuls.

A significant observation in the CBQ 2016 survey was the relative abundance of both the Straw-headed Bulbul and White-rumped Shama. Both species continued to do very well on Pulau Ubin but it is critical that the authorities and the public remain vigilant against potential poaching here and in other parts of Singapore.

OLYMPUS DIGITAL CAMERA

The White-rumped Shama continues to do well in Ubin with 31 contacts during the survey. The count maybe due to it being very vocal at this time of the year.

As also noted in 2016 it is inevitable that biases exist for all rapid survey and census. The most obvious bias is that this is a rapid one day count lasting only 2 to 2.5 hours. Experience of participants is also a contributing factor with the more experienced participants recording more birds heard or sighted. This survey is conducted at a time where some species may be more vocal than others and most if not all migrants are absent. Another issue involves the detection bias towards species that are more vocal or active at the edges of habitats as the selected routes were along existing roads, trails or boardwalks. But in general, this survey does provide a fairly good picture of the type of common resident birds that you can expect to see on a bird walk on the island in the middle of the year.

Rounding up the top three are the Swiftlets also with 31 contacts.

COMMENTS

We are glad that there was a six-fold increase in participation. The Pesta Ubin Commonest Birds Quest continued to provide the opportunity to the public to participate in a citizen science project. The data collected over an extended duration could be used to monitor changes to the avifauna of Pulau Ubin and ultimately the state of the environment here. A common bird today may become very rare or even become extinct tomorrow if its habitat is altered irreversibly or destroyed.

Pulau Ubin Nocturnal Bird Survey Report

Nocturnal Bird Survey Report at Pulau Ubin by Sandra Chia.

The nocturnal fauna of Singapore has long held the fascination of many nature-enthusiasts. From the inquisitive stare of the Buffy Fish Owl to the wide-eyed Sunda Scops Owl, nocturnal birds have been seen throughout the island, and garnered the attention of many. Several of us have seen owls on Pulau Ubin before, but how many are there exactly? And where?

To get a better understanding of the diversity and numbers of nocturnal birds present on Pulau Ubin, the Bird Group in collaboration with Nparks conducted its first ever Ubin night survey. On 22 July, while hordes of people were headed home after a long day at the beach, a group of us were headed towards Changi Point Ferry Terminal for a very different reason. Boarding a bumboat, 11 of us set off into the sunset for Pulau Ubin. Headed by an experienced leader, the group was further split into three teams of three to four surveyors each. Three survey routes were established, covering the east, west and central portions of Ubin.

Upon reaching the starting point of each survey route, the group embarked on a slow walk back to the kampong centre, that took about 2 hours. Whenever a nocturnal bird was encountered or heard, the species and coordinates of the encounter were jotted down and compiled into a datasheet thereafter. When nocturnal mammals were encountered, the species and location of the encounter were likewise noted down, on a separate datasheet.

In total, 16 individual birds were seen or heard. The most numerous were the Large-tailed Nightjar and Sunda Scops Owl, of which 6 individuals of each species were encountered throughout the survey. The Buffy Fish Owl and Black-crowned Night Heron were encountered once each, while the Savanna Nightjar was encountered twice. To our delight, Greater Mousedeer were seen by all three groups and one group even saw a herd of wild boar with 3 adults and 13 piglets!

datauri-file[1]

There is probably a much wider diversity and greater number of nocturnal birds on Ubin, based on historical sightings as well as the fact that there are many parts of Ubin our routes did not cover. For example, all species of owl known in Singapore are recorded on Ubin except for the Short-eared Owl. We hope to continue to conduct more nocturnal census and hopefully uncover more nocturnal birds on Ubin.

The Bird Group is grateful to all the survey leaders for leading the surveys and to all participants who assisted. The survey leaders included Lim Kim Keang, Willie Foo and Alfred Chia and participants included Sandra Chia, Emmanuel Goh, Dillen Ng, Lim Hong Yao and Tan Julin. We would also like to thank Robert Teo, Grace Ang, Joseph Lin and Jacky Soh from NParks for supporting our work.

Singapore Bird Report – July 2017

We have several very early migrant sightings this month. Is it due to global warming? Maybe the birds are more sensitive to the changes than us.

Wood Sandpipers Goh Cheng Teng

Composite photo of a Wood Sandpiper flying over Jurong West by Goh Cheng Teng. First migrant shorebird to arrive this season.

A Brown-backed Needletail Hirundapus giganteus was photographed by Francis Yap with Keita Sin at Jelutong Tower on 19th, two weeks earlier than the previous early date. Keita Sin did better when he came across a Pacific Swift Apus pacificus flying across Punggol Barat on 22nd, more than a month from the last early date of 3rd Sept. On 16th, Goh Cheng Teng photographed a Wood Sandpipers Tringa glareola flying over Jurong West. This is 2 days ahead of the previous early arrival date. Four days later Alan OwYong flushed another Wood Sandpiper from a wet patch at Bulim grasslands. On the same day and place, Ben Choo photographed a female leucopsis White Wagtail Motacilla alba at the canal there. The jury is out if this is over summering or early arrival as the previous early arrival date is 9th September 2016 (Richard White, Marina Barrage).

1-Ben Choo

Ben Choo’s shot of a female White Wagtail in breeding plumage at a canal at Bulim raise the question of its arrival or over-summering status.

The sighting of the Wood Sandpiper prompted Francis Yap to stake out Seletar Dam and he was rewarded with shots of Common Greenshank Tringa nebularia and Little Egrets Egretta garzetta there on 24th. A day later, three Common Redshanks Tringa totanus were reported by Robin Tan and a Common Sandpiper Actitis hypoleucos by Lim Kim Seng, both at Sungei Buloh Wetland Reserve.

On 26th Francis returned to Seletar Dam and notched up two more new arrivals. Three Lesser Sand Plovers Charadrius mongolus and a Barn Swallow Hirundo rustica, normally the harbinger of the start of the migrant season. But it was beaten by an Asian Brown Flycatcher Muscicapa latirostris photographed by Thio Hb at Kampong Java Park on 20th. Our previous early arrival date for this flycatcher was 9th August. Fadzrun A. shot a flock of 46 Lesser Sand Plovers at Kranji Dam on 31st. The migrating shorebirds have arrived!

We ended the month with a Watercock Gallicrex cinerea crashing into the Beach Villas at Resort World Sentosa on 31st. Tan Kok Yeang was kind enough to send us the photo. The injured bird was handed over to Nparks. This is a new addition to Sentosa but we had record of this migrant arriving as early as 8th of July. We can expect a busy month ahead as more migrants will be making landfall at various parts of the island.

Our residents put up a good show as well. The most unexpected sighting was a rare Mangrove Whistler Pachycephala cinerea turning up at Marina East on 30th, a first for the south.  We had very few mainland records as this is a mangrove island dweller. We had to thank Mike Hooper for this record.  Koh Liang Heng followed up the next day and found it at the same place. The Mangrove Pittas Pitta megrahyncha were reported at Pulau Ubin and Pasir Ris Park on 8th and 17th respectively ( Willie Foo and Lim Kim Keang). The Blue-winged Pittas Pitta moluccensis were heard calling at the Bulim Forest by Wing Chong and James Tann and at Choa Chu Kang Cemeteries by Martin Kennewell both during the Mid Year Bird Census on 8th. They may be nesting but no nests were found so far.

An Oriental Pied Hornbill Anthracoceros albirostris was seen at Gardens by the Bay by Veronica Foo on 27th, a surprising first for GBTB. From one Lesser Whistling Duck Dendrocygna javanica to ten at the Lorong Halus ponds on 17th was the welcome news from Lim Kim Keang. We continue to receive records of House Swifts Apus nipalensis over the months. Three birds were seen at the East Coast Parkway near Fort Road by Lim Kim Chuah on 14th. Signs that this species maybe making a comeback.

_7152243

The juvenile Greater Green Leafbird at Dairy Farm is a good indication of the successful breeding of this uncommon species.

The other good news were sightings of juveniles of some of the uncommon species, confirming their breeding success. A Greater Green Leafbird Chloropsis sonnerati juvenile was photographed feeding on a White Mulberry Tree at Dairy Farm Nature Park on 15th. We do not have any breeding records for this leafbird and this is only the second record of a juvenile.

A young male Violet Cuckoo Chrysococcyx xanthorhynchus was seen being chased by an female Sunbird at Jurong Eco Garden on 18th. Lim Kim Keang also reported seeing the same there a few weeks earlier. Over at the Lorong Halus ponds, a pair of Little Grebes Tachybaptus ruficollis were seen feeding a juvenile on 25th. All the three above records came from Alan OwYong. The last young bird reported was a Red-legged Crake Rallina fasciata photographed at Pasir Ris Park on 31st by Seng Alvin, a first for the park.?

This young Violet Cuckoo was being chased around Jurong Eco Garden by a female Sunbird.

Finally two non-breeding visitors were reported this month. A Crested Serpent Eagle Spilornis cheela was seen perched at Science Park 2 on 13th by Francis Yap and a pair of Black Hornbills Anthracoceros malayanus at Sentosa flying towards Siloso on 30th seen by Colin Richardson, a visiting birder (posted in ebird, reported by Martin Kennewell). This hornbill was recently added to the checklist based on the records from Pulau Ubin, where one was seen by Adrian Silas Tay on 22nd.

Singapore’s last surviving Malkoha.

Contributed by Alan OwYong.

The last surviving Malkoha, the Chestnut-bellied Phaenicophaeus sumatranus, that was once confined to the Singapore Central Forest and Bukit Timah Nature Reserve has adapted well to the forest fringes and buffer nature parks since the start of the century. But our early specimens were collected from the mangroves along Kranji River, Jurong and Seletar, Sungei Sembawang and Ulu Pandan. It must be this adaptability that sees it surviving until today. Its closest relative here, the Black-bellied Malkoha P. Diardi, died out in the 1950s due to its dependence on denser forests in the interior that were logged ( per cons Yong Ding Li). So did the smaller Raffles’s and Red-billed Malkohas. We can learn from these extinctions and manage our forest to protect our last malkoha and other similiar species from meeting the same fate.

Chestnut-bellied Malkoha at JEG

Rare open view at the Jurong Eco Gardens, where nesting have been recorded.

Mainly arboreal, it hops from branch to branch looking for large insects and small vertebrates at the forest canopies.  Unlike cuckoos, it builds its own nest and care for its young on its own. This uncommon breeding resident is both globally and nationally near-threatened.

Chestnut-bellied Malkoha at Jelutong

Jelutong Tower is the best place to get eye-level shots of this canopy feeder. Its diet of large insects makes it vulnerable and is listed as nationally near-threatened.

I have seen them foraging along the Mandai Lake Road in the early 2000s. Those who remembered the Mandai Orchid Gardens will know of the few nesting records there. One of the nest was inside a low ficus tree right next to the souvenir stall at the Gardens close to the visitors path. Another nesting was outside the Bukit Timah Visitor Center at roof top level. The eggs on an open flimsy nest were at the mercy of the preying Long-tailed Macaques. The most recent nesting records however came from Jurong Eco Gardens. These Malkohas can still be seen there today.

Besides keeping the Central Forest intact, the creation of buffer nature parks augurs well for the survival and well being of this jewel of our forest.

Singapore Bird Report – June 2017

June may be a quieter month, but great to see so many postings on fledglings, rare and uncommon residents from across the island. We will try to cover some of the more interesting sightings including a few over stayers and unexpected locations of these sightings.

Yong Ding Li led a census for the Straw-headed Bulbul Pycnonotus zeylanicus at Pulau Ubin on the morning of 4th as part of this year’s Pesta Ubin Festival. They counted a total of 68 birds, confirming that Pulau Ubin has the highest density for this globally endangered species anywhere in the world.

The newly fledged Grey-rumped Treeswift chick at Ang Mo Kio by Gerald KC Lim

Danny Khoo reported the successful fledging of the Grey-rumped Treeswift Hemiprocne longipennis chick at Ang Mo Kio park on 10th and the Red-crowned Barbet Megalaima rafflesii chick at the Mandai Track 7 on 16th. Great to see that this uncommon forest resident is doing fine. An adult White-headed Munia Lonchura maja was seen feeding three juveniles at a suburban estate at Mount Sinai on 15th by Gerald KC Lim. These may be released birds.

The unwelcome breeding record came from the canal leading to Kranji Marshes where an adult Common Waxbill Estrilda astrild was feeding two youngs on 12th (Birding Dawn). This is the first record of these juveniles, which means that they have adapted to our weather. Our seed eaters will be impacted if they flourish.

Con Foley and friends sighted a lone straggler Barn Swallow Hirundo rustica flying over the Kranji Marshes on 3rd. They have been recorded as late as 11th June. The Black Bittern Dupetor flavicollis was photographed at the Gardens by the Bay on 5th (Francis Yap). Over at Pulau Tekong, Frankie Cheong reported that up to 20 Red-necked Stints, Calidris ruficollis some in breeding plumage were still around on 5th. The previous late date for this shorebird was 28th May. Staying in Tekong, two white and one dark morph Pacific Reef Egrets Egretta sacra were seen together on the 12th as well. Frankie Cheong’s photo below.

Most of our recent records of the Great-billed Heron Ardea sumatrana came from Chek Jawa and Sungei Buloh, great to receive a record from Christina See of one at Pulau Hantu on 14th. The Southern Islands have always been their stronghold.

The summer visitor Horsfield’s Bronze Cuckoo Chrysococcyx basalis seen last month was spotted again by Fadzrun A. at the same grasslands at Seletar end on 5th. It was also photographed at the Mangrove Arboretun at Pulau Ubin by Joseph Lin from NParks on 15th (per Robert Teo’s report). As far as we know this is the first record for Pulau Ubin.

Staying in Ubin, the on-off Oriental Darter, Anhinga melanogaster a non-breeding visitor, was seen again at the Pekan Quarry at Pulau Ubin on 4th by Alfred Chia.

Rare residents reported this month include three House Sparrows Passer domesticus over at Jurong Island on 2nd (Low Choon How), a Chinese Hwamei Garrulax canorus at Sentosa on 3rd by CT Goh and Sandra Chia, a Black-headed Bulbul Pycnonotus atriceps seen at Jelutong Tower on 18th by Martin Kennewell. An uncommon White-rumped Shama Copsychus malabaricus  was recorded at Dairy Farm NP on 23rd by Alan OwYong.

Other interesting resident species reported were Abbott’s Babbler Malacocincla abbotii at Kranji Marshes on 3rd by Con Foley and friends and another Abbott’s Babbler at Chek Jawa on 17th by Atish Banerjee. A forest Greater Coucal Centropus sinensis at Pasir Ris Park on 4th by Lim Kim Seng and a Chestnut-winged Babbler Stachyris erythroptera heard calling at the Lakeview Estate on 18th by Marcel Finlay. He had seen three birds last month along the Petai Trail. It looks like the Red-wattled Lapwings Vanellus indicus are doing well at the Kranji Marshes. Martin Kennewell counted 27 of them there on 17th.

A few resident species were reported in unexpected locations this month. A Spotted Wood Owl Strix seloputo was seen twice at the Varsity Condo at Pasir Panjang  on 7th and 16th by Gan Cheong Wei. He also reported a leafbird there on 17th. Unfortunately it was not identified. The seldom visited Admiralty Park at Woodlands was the home of a pair of Red-legged Crakes, Rallina fasciata spotted by Alan OwYong on 8th. Lioe Kim Swee reported seeing two unidentified crakes there in 2015.  A roosting Savanna Nightjar Caprimulgus affinis was photographed by Seng Alvin at Tampines Eco Green on 21st.

Good to hear that the Lesser Whistling Duck Dendrocygna javanica returning to the Lorong Halus ponds on 26th even though it was just one bird (Martin Kennewell). Our previous record was in 2013 (Ho Hua Chew). Lena Chow was excited to find the Blue-eared Kingfisher Alcedo meninting at the Dairy Farm NP on 26th. Lim Kim Chuah said that he had seen it along one of the streams there before. Another sign of this forest kingfisher spreading. Many thanks for all your records.
