NSS Bird Group Report – Feb 2019

February continues to dazzle with exciting migratory species, such as the elusive Slaty- legged Crake at Admiralty, rare Sakhalin Leaf Warbler & Green-backed Flycatcher; rare resident race Ruddy Kingfisher at SBWR, as well as unusual sightings of familiar residents in new places. Chinese New Year treats include the Crakes and Chestnut-winged Cuckoo at Lorong Halus Wetland.

Slaty-legged Crake at Admiralty Park

The Slaty-legged Crake Rallina eurizonoides is rare winter visitor and passage migrant that is elusive and seldom encountered. Although listed as being of least concern (BirdLife, 2016), the species is said to be in decline. A rather large crake measuring about 25cm in length, the species is said to breed across South Asia to the Philippines, and certain populations is known to migrate within the region.

The most recent report concerned one that was photographed in a basement carpark at Haig Road in December 2018, as well as a hitherto unreported sighting at Admiralty Park on 3 December 2018 by Luke Milo Teo, who had been unsure of the species of crake he had photographed until the postings of the Haig Road bird. These were preceded by one found dead at Sentosa in December 2016, and a record on Jurong Island in January 2015. Thus, a sighting on 7 February 2019 at Admiralty Park by veteran birder Morten Strange, and his wife Bee Choo, was therefore greeted with much enthusiasm.

The crake was also seen on 8 February 2019 by Keita Sin. The last confirmed sighting of the crake was on 9 February 2019, reported by Khoo MeiLin, who noted that the crake, along with several White-breasted Waterhen Amaurornis phoenicurus, frequented an evaporating pool during twilight hours to bathe before returning to the thick undergrowth within the vicinity.

Central Catchment Nature Reserve (CCNR)

Sightings within the CCNR were confined to the initial days of February. On 2 February 2019, an Oriental Dwarf Kingfisher Ceyx erithaca (black-backed subspecies), Crow- billed DrongoDicrurus annectans and an unidentified Hawk Cuckoo were spotted around the vicinity of Dillenia Hut by Thio Hui Bing. Another Oriental Dwarf Kingfisher (black- backed subspecies) was spotted on 6 February 2019, as was a Green-backed Flycatcher Ficedula elisae by Raghav Narayanswamy. The same day also yielded a Sakhalin Leaf Warbler Phylloscopus borealoides at the MacRitchie Reservoir Park for Geoff Lim.

Prior to the Chinese New Year season, Lorong Halus was a hotbed of activity due to the continued appearance of two rallids and a charismatic cuckoo. A Chestnut-winged Cuckoo Clamator coromandus on 2 February 2019 was reported by Lee Yue Teng, while a Ruddy-breasted Crake Porzana fusca was seen on the same day by Kok M Lee. Also spotted and posted on social media was the elusive Baillon’s Crake Porzana pusilla. The crake had been sighted in end December 2018 and continued to be seen in the reedbeds at the Lorong Halus Wetland during the Chinese New Year holidays.

The island yielded an Orange-headed Thrush Geokichla citrina at Imbiah Falls on 28 February 2019 when Lim Kim Seng and David Mostardi visited the site.

Western Singapore

Western Singapore continued to provide an astonishing number of reports, given that many local Important Bird Areas are clustered in this part of the island nation.

The area around Kranj Marsh continues to support a wide variety of species. The marshes themselves hosted a Watercock Gallicrex cinerea, which was spotted on 3 February 2019 by Veronica Foo; while a Savanna Nightjar Caprimulgus affinis was encountered at Turut Track on 22 February 2019.

The nearby canal at Lim Chu Kang Avenue 3 supported a variety of species; a Pintail Snipe Gallinago stenura on 2 February 2019 by Benson Brighton, a Greater Painted Snipe Rostatula benghalensis on 3 February 2019 by Lim Kim Seng, an Eastern Yellow Wagtail Motacilla tschutschensis, two Common Moorhen Gallinula chloropus, three White Wagtail Motacilla alba ocularis, four Wood Sandpiper Tringa glareola, and five Little Ringed Plover Charadrius dubius on 5 February 2019 by Yong Ding Li, Koji

Sungei Buloh Wetland Reserve (SBWR) continued to surprise birders. On 4 February 2019, a rare resident race Ruddy Kingfisher Halcyon coromanda minor with a strong purplish gloss to its back was photographed by Siew Mun. Several days later on 7 February 2019, seven Lesser Adjutant Leptoptilos javanicus were seen by Low Choon How, the highest number to date. An Oriental Darter Anhinga melanogaster was seen on 11 February 2019 by Lim Kim Keang and Veronica Foo.
