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

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

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

Some highlights from this year’s census include:

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

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


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


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

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

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

Singapore Bird Report – March 2019

by Geoff Lim & Alan OwYong, edited by Tan Gim Cheong

March 2019 continues to witness the return migration of birds back to their northern breeding grounds. We were also treated to the arrival of a solitary Asian Openbill, a small species of stork that last visited us in January 2013.

Openbill Visitation

On 14 March 2019, an Asian Openbill Anastomus ocsitans was spotted at Sungei Buloh Wetland Reserve (SBWR) by visiting Australian birders, Grant and Clare Morton, who sent an email to Nature Society (Singapore) to report the sighting. The bird was subsequently spotted again at SBWR,  sparking off an intense hunt for the bird in the days that ensued.

The first record of the species occurred three years ago, on 23 January 2013, when six birds were found feeding in a waterlogged grass patch close to Seletar Airport. These were thought to be part of larger groups of birds that flew southwards down Peninsula Malaysia. The appearance in 2013, along with the current record, represent the southernmost record of the species to date. Further information about the sighting can be found here.

Central Catchment Nature Reserve (CCNR)

Migrants continued to be observed within the CCNR in the month of March. A Grey Nightjar Caprimulgus jotaka was seen on 5 March 2019 from Jelutong Tower by Kelvin Ng while Eastern Crowned Warblers Phylloscopus coronatus were spotted at Venus Drive and Windsor Nature Park on 10 March 2019 by Benson Brighton and Russell Boyman, respectively. On 15 March 2019, a juvenile Malayan Night Heron Gorsachius melanolophus was seen at Hindhede Nature Park as it stalked along the forest floor and was stumbled upon by Fadzrun Adnan and Richard White. The last time we had a publicly recorded sighting of the heron was at the Singapore Botanic Gardens in April 2018.

The following week yielded reports of flycatchers in Singapore’s central green core. A Yellow-rumped Flycatcher Ficedula zanthopygia was spotted at Dairy Farm Nature Park on 17 March 2019 by Zhang Licong, as was an Asian Paradise Flycatcher Terpsiphone species, which was fleetingly seen at Lower Pierce by Vincent Lao, who did not have sufficient time to identify it further. A Ruddy Kingfisher Halcyon coromanda was seen at Venus Link on 22 March 2019 by Richard White, while a Black Bittern Dupetor flavicollis was spotted at the Singapore Quarry on 24 March 2019 by Veronica Foo.

Northern Singapore

A Grey Wagtail Motacilla cinerea was seen around the vicinity of Seletar Camp on 13 March 2019 by Timothy Chua, who also spotted a Dark-sided Flycatcher Muscicapa sibirica on 17 March 2019 at Woodlands Town Park.

Eastern Singapore

Birders at Pasir Ris Park noted the movement of cuckoos during the month of March. A Hodgson’s Hawk Cuckoo Hierococcyx nisicolor was seen on 8 March 2019 by Wong Sangmen, as was another spotted on 26 March 2019 by Alvin Seng. Three sightings of a Plaintive Cuckoo Cacomantis merulinus were made on 17 March 2019 by Feroz, while a Large Hawk Cuckoo Hierococcyx sparveroides was seen on 19 March 2019 by Fabius Tan. The last week of March yielded a male Yellow-rumped Flycatcher Ficedula zanthopygia on 26 March 2019 by Wong Sangmen, a Mugimaki Flycatcher Ficedula mugimaki on 28 March 2019 by Khoo Mei Lin and a Von Schrenck’s Bittern Ixobrychus eurhythymus on 31 March 2019 by Wong Keng.

Further afield, two Jerdons Baza Aviceda jerdoni was spotted at the Pasir Ris Farmway 3 on 10 March 2019 by Vincent Lao, while a Chinese Egret Egretta eulophotes was seen on 23 March 2019 on Pulau Tekong by Frankie Cheong. Rare non-breeding visitors reported from this regions included a pair of Buff-rumped Woodpecker Meiglyptes tristis species on Pulau Ubin on 7 March 2019 by Chris Sanderson.

Central Singapore

A Hodgsons Hawk Cuckoo Hierococcyx nisicolor was spotted lurking in the remnants of Bidadari on 10 March 2019 by Mike Hooper.

Southern Singapore

The southern green lung that is collectively formed by Gardens-by-the-Bay and Satay-by-the-Bay attracted several species of migratory and resident birds during the month of March 2019. On 2 March 2019, a Yellow-browed Warbler Phylloscopus inornatus was spotted in the Gardens by Martine Ruane. A juvenile Black-crowned Night Heron Nycticorax nycticorax was seen at the pond next to Satay-by-the-Bay on 14 March 2019 by Veronica Foo, while a Blue-eared Kingfisher Alcedo meninting made its appearance in the canals near the Meadow on 25 March 2019.

A Brown Hawk Owl Ninox scutulata appeared in a tree near the pond next to Satay-by-the-Bay on 26 March 2019 as reported by Andy Chew. This is an unusual location for the species which is usually seen/heard around the central forests only. It continued to be seen over the next few days until the last report on 31 March 2019 made in social media.

Farther afield, we received a report of a Pacific Swift Apus pacificus over Henderson Wave on 5 March 2019 by Keita Sin, who also reported movement across the hills of Kent Ridge Park on 8 March 2019 of one Common Buzzard Buteo buteo and three Grey-faced Buzzard Butastur indus.

Western Singapore

The Kranji Marsh-Neo Tiew area continued to yield reports during this month as well. Social media continued to report the presence of wintering Black Drongo Dicrurus macrocercus at Harvest Lane, while five Oriental Pratincole Glareola maldivarum were spotted on 22 March 2019 at the same location by Deborah Friets. Twelve Wood Sandpiper Tringa glareola were also spotted at Harvest Lane on 24 March 2019 by Alan Chou, as was a “Swintail” Snipe Gallinago sp. on 26 March 2019 by Gabriel Koh, and a Stejnegers Stonechat Saxicola stejnegeri on 29 March 2019 by Alan Owyong, which is later than the previous extreme date of 28 March for this species (note: the individual was still around well into April). Within Kranji Marsh, a Javan Pond Heron Ardeola speciosa was spotted on 23 March 2019 by Lim Kim Seng.

Sungei Buloh Wetland Reserve (SBWR) continued to support shorebirds and waterbirds. Apart from the spectacular report of a solitary Asian Openbill mentioned above, the Reserve continued to attract species such as Terek Sandpiper Xenus cinerus on 23 March 2019 by Gabriel Koh, Khoo Mei Lin and friends, the regular congregation of Great Egrets Ardea alba reported on 30 March 2019 by Lee Van Hien, one male Japanese Paradise Flycatcher  Terpsiphone artrocaudata on 31 March 2019 by Marvin Heng, and five thermaling Lesser Adjutant Leptoptilos javanicus, also on 31 March 2019 by Adrian Silas Tay.

Birders and photographers drawn by the Grey-headed Fish Eagle along Pandan Canal reported other species. A Chinese Pond Heron Ardeola bacchus was seen on 3 March 2019 by Steven Wong, as was an Abbotts Babbler Malacocincla abbotti and Little Bronze Cuckoo Chrysococcyx minutillus on 20 March 2019 by Alan Owyong. A Black-capped Kingfisher Halcyon pileata was reported on 29 March 2019 by Ash Foo, a new record for the location.

Other species reported from this region include a pair of Oriental Magpie Robin Copsychus sauluris on 6 March 2019 at Tuas Naval Base by Kerry Pereira,  a first for this part of Singapore. Within the compounds of the Jurong Bird Park on 31 March 2019, two Greater Coucal Centropus sinensis were seen together before one of them surreptitiously flew to an embankment and waited for about a minute and a half or so before walking into the undergrowth and disappearing into the thick scrub, leaving Geoff Lim to wonder if they were nesting.

Breeding-related activities

Nesting by Collared Kingfisher Todirhampus chloris was reported on 10 March 2019 at Queens Drive by Cheng Li Ai; another pair was followed by many bird photographers in Clementi during the same period, reported by Khoo Mei Lin, and the chicks fledged on 19 and 20 March 2019. Other breeding behaviour reported include the sighting of the critically endangered Straw-headed Bulbul Pycnonotus zeylanicus on 9 March 2019 at Bukit Batok Nature Park by Lim Kim Chuah, who saw a pair with a juvenile, suggesting that breeding had taken place within the Park.

Asian Openbill-Singapore’s 2nd Record

On 17 March 2019, Beng Neo’s facebook post of an Open-billed Stork, Anastomus oscitans, taken at Sungei Buloh Wetland Reserve caused a stir among the birding community here. The next day birders and photographers lined up on the main bridge, hoping to tick off their lifers. They were not disappointed and all went home happy with great sightings and shots.

Apparently Clare and Grant Morton, visiting birders from Australia first spotted this stork flying over the main hide on 14 March. They reported by email to the Nature Society (Singapore) and later confirmed it with a photo on the 19 March. Their sighting constituted only our second record of this stork in Singapore.

Our first record was on 23 January 2013 when six birds were spotted feeding in an open flooded field at Seletar North. They were part of a larger flock that made its way down south from Thailand along the West Coast of Peninsular Malaysia. This movement may be due to the dry conditions back in Thailand and the lack of food sources.

This month there were several postings of this stork on the Wild Bird Club Malaysia Facebook pages. 15th at Bota Kiri and Kinta NP on 3rd both in Perak and Tanjong Karang, Selangor on 11th. According to Tou Jing Yi they can be found in many parts of the West Coast and are still supplemented by migrants.

Mahesh Krishan

Mahesh Krishnan caught it flying towards him at the main pond. The Asian Openbill is a common resident of India and parts of Indochina. Hundreds can be seen roosting in temples in Bangkok.


The abundance of mollusc at the main ponds will hopefully prolong its stay here. This photo made it look like they are using the gap to crack the snails but they actually pick out the flesh with the curved tip of its mandible.

Many thanks to Beng Neo, Clare and Grant Morton, Mahesh Krishnan, Khoo Mei Ling and Alan OwYong for the use of their photos and to Clare and Grant Morton for their record.
