Asian Emerald Cuckoo, Living Lab, Pulau Ubin, 5 Mar 2021, by May Swales

A number of rarities showed up in March 2021. An Asian Emerald Cuckoo Chrysococcyx maculatus, for which there are less than five records, was photographed by May Swales at Living Lab, Pulau Ubin on 5 Mar 2021. The female was present till 8 March (Wong Wai Loon).

At Lim Chu Kang Lane 3, Lau Jia Sheng photographed the elusive Green Sandpiper Tringa ochropus on 6 Mar 2021. And at Marina East, Linda Teh photographed a Black-winged Stilt Himantopus himantopus that made a brief visit on 19 Mar 2021. On 19 Mar 2021, another 1-day bird, a female Blue Rock Thrush Monticola solitarius visited Catalina Tong’s high rise balcony along Thomson Road opposite Singapore Polo Club.

The Cotton Pygmy Goose Nettapus coromandelianus that showed up at Bishan-Ang Mo Kio Park last month was joined by a second bird on 2 Mar 2021 (Yk Goh) but both birds promptly disappeared the next day. The Sakhalin Leaf Warbler Phylloscopus borealoides noted at Sungei Buloh Wetland Reserve (SBWR) in February continued to be present from 1 Mar 2021 (Wilson Chua) till 13 Mar 2021 (Leslie Loh).

A rare Black-naped Monarch Hypothymis azurea put up a brief appearance at Jurong Lake Gardens on 15 Mar 2021, photographed by Vincent Chin and Joseph Pher. Five days later, on 20 Mar 2021, one monarch, probably the same individual, showed up at Clementi Woods Park (Frank Rheindt) and remained for most of the day but disappeared thereafter.

At Dover Road on 8 Mar 2021, a pond heron that started to moult into breeding plumage showed signs of it being an Indian Pond Heron Ardeola grayii (Art Toh), and it would develop into full breeding plumage over the course of the month. A male Japanese Paradise Flycatcher Terpsiphone atrocaudata with long tail showed up at Coney Island on 18 Mar 2021 (Richard Wee) and those who braved the rain in the afternoon were rewarded with views of its exquisite beauty.

There were four reported nestings for the Black-naped Oriole. One nest was observed outside Sophia Residences on 18 Mar 2021 by Eric Tan. On 20 Mar 2021 Khoo MeiLin reported a nest at West Coast Park being raided by a pair of Oriental Pied Hornbills which were undeterred by the mobbing by the adult orioles. Tan Tze Siong reported a successful nesting at Bukit Timah with two chicks fledging, he also noted that the parents fed the chicks with a baby bird. At Satay by the Bay, a nest with two chicks was observed on 15 Mar 2021 (Steve Ang), it was unusually open, perhaps as a result of the nest tree shedding leaves. On 17 Mar 2021 Andy Chew saw a House Crow Corvus splendens taking one chick from the nest, and killing it. On 19 Mar 2021, another Black-naped Oriole tried to raid the nest but was driven away, and on 22 Mar 2021, the remaining chick fledged (David Kow). This last pair fed their chicks with small geckos, grasshoppers and small round fruits (16 Mar 2021, Tan Gim Cheong).

At Pulau Ubin on 8 Mar 2021, a male Oriental Pied Hornbill Anthracoceros albirostris was feeding its family through the slit in a man-made nestbox, observed by Lee Chin Pong. Unfortunately for theOriental Pied Hornbill nest in the vicinity of Hampstead Wetlands, one chick was found dead on 14 Mar 2021 by Justin Jing Liang, and another chick dead on 19 Mar 2021, observed by Valli Nalla. On 21 Mar 2021 the male was still seen feeding the female through the slit (Tuck Loong), but the hole was reported as having been unsealed on 22 Mar 2021 by a birder who goes by the initials “R L”.

Three nestings were also reported for the House Crow, all of which were parasitized by the Asian Koel Eudynamys scolopaceus. At Marina East on 9 Mar 2021, Neo Jinju observed a koel chick being hosted by the crows. At Fort Road car park on 25 Mar 2021, a nest with three crow chicks and one koel chick was observed by Sylvester Goh.

Singapore Bird Report – March 2020

By Geoff Lim & Isabelle Lee.
and Tan Gim Cheong (ed.)

March continued to see the reporting of spectacular species – the 3rd record of the Asian Emerald Cuckoo, a male, at Ghim Moh; the continued presence of the 3rd recorded Chinese Blue Flycatcher; and visitation by the globally threatened Chinese Egrets at Pulau Ubin.

Chinese Egret

On 16 March 2020, Richard White and Francis Yap was at Chek Jawa, Pulau Ubin at low tide when Richard spotted a Chinese Egret, Egretta eulophotes, a rare visitor, on the intertidal zone. The egret continued to frequent the tidal flats on subsequent days, giving many birders a chance to see this globally threatened species in Singapore. T. Ramesh was delighted to spot the egret on 20 March 2020 just before the low afternoon tide and recorded some videos of its active feeding behaviour. On 31 March 2020, Vincent Ng recorded three individuals feeding together. The species was previously reported with a fair degree of regularity at Pulau Tekong only.

According to Dr. Yong Ding Li, “the egret can be tricky to ID, especially if in the non-breeding plumage, and seen from a great distance. But a nicely written article by Nial Moores shows that foraging behaviour can be a great clue towards its identification – especially its more erratic and ‘kancheong‘ movements!” This was also observed by T. Ramesh in his short notes and video.

Asian Emerald Cuckoo

Singapore’s third record of the Asian Emerald Cuckoo, Chrysococcyx maculatus, came in the form of a splendid male. The two earlier records were at Upper Seletar Reservoir Park in May 2006, when an immature and a female appeared, and at Sentosa between late December 2017 and January 2018, when two females appeared. Social media reports indicated that the bird was first discovered on 23 March 2020 along the park connector at Ghim Moh. This bird continued to stay at the location until the end of the month, feeding on the abundant caterpillars that flourished in the trees.

The species is regarded at being of Least Concern and can be found from the Himalayas, through Nepal and Bhutan, NE India, Bangladesh and S China, through Myanmar, NW Thailand, N Laos and N and central Vietnam. During winter, it flies to S India, Sri Lanka, Andaman and Nicobar Islands, Indochina and Malaysia, with small numbers arriving at Sumatra (Payne, 2020). First reports of the bird arriving at the Penang Botanical Gardens were posted on social media around 16 December 2019 (Kelvin Low), and 19 December 2019 (Chan Kai Soon). Hence, it is possible that the bird encountered in March 2020, may well be a returnee heading back to its northern breeding grounds.

Central Catchment Nature Reserve (CCNR) and Fringe Parks

The core CCNR continued to support interesting forest species. These included a Sakhalin Leaf Warbler, Phylloscopus borealoides, which was spotted on 4 March 2020 at Mandai Track 15 by Choong YT, a non-breeding visitor in the form of a Cinereous Bulbul, Hemixos cinereus, at Bukit Timah Nature Reserve on 8 March 2020, as seen by Lim Kim Chuah, the gem of an Oriental Dwarf Kingfisher, Ceyx erithaca, on 12 March 2020 along Rifle Range Link by Choong YT, and a Mugimaki Flycatcher, Ficedula mugimaki, on 14 March 2020 by John Ascher. Birders and photographers alike continued to be delighted to find the very rare Chinese Blue Flycatcher, Cyornis glaucicomans, from 1 March 2020, through to 14 March 2020, as seen by Norhafiani A Majid, and by Geoff Lim on 16 March 2020 (the same individual was first recorded on 25 February 2020). This presents the possibility that the species may be over-wintering in Singapore, albeit undetected.  Up to two Green-backed Flycatcher, Ficedula elisae, were also seen by Geoff Lim and Norman Wu on 16 March 2020.

At Dairy Farm Nature Park an Orange-headed Thrush, Geokichla citrina, was reported on 4 March 2020 by Steven Cheong. Two owls were reported by Choong YT on 17 March 2020, a Barred Eagle-Owl, Bubo sumatranus, (heard only), and a Northern Boobook, Ninox japonica, that was rehabilitated and released by Jurong Bird Park/NParks. About a week later, on 24 March 2020, three Blue-winged Leafbird, Chloropsis cochinchinensis, were seen and reported by Oliver Tan, while an Abbott’s Babbler, Malacocincla abbotti, was reported on 28 March 2020 by Mike Hooper.

Windsor Nature Park proved to fruitful, with a Jambu Fruit Dove, Ptilinopus jambu, seen on 14 March 2020 by Mike Hooper, a Black-crested Bulbul, Pycnonotus flaviventris, reported on 16 March 2020 by Oliver Tan, and a Blue-rumped Parrot, Psittinus cyanurus, seen and reported feeding on starfruit on 18 March 2020 by Kwok Tuck Loong.

A Malayan Night Heron, Gorsachius melanolophus, was reported on 2 March 2020 on the Red Brick Path by Kwok Tuck Loong, while a Greater Painted Snipe, Rostatrula benghalensis was seen at the Eco-Lake of the Gardens on 5 March 2020 by Laurence Eu, and subsequently reported until 12 March 2020 (David Fur). During this period, a Von Schrenck’s Bittern, Ixobrychus eurhythmus, was reported on 8 March 2020 by Mike Hooper, while a Taiga Flycatcher, Ficedula albicilla, (possibly the same individual – Singapore’s first record – first seen on 30 November 2019) was reported on 14 March 2020 by Marcel Finlay and on 20 March 2019 by Myron Tay. At the end of the month, a Hooded Pitta, Pitta sordida, was reported on 30 March 2020 by Choong YT. On the fringe of the Gardens, a Yellow-browed Warbler, Phylloscopus inornatus, was reported from Cluny Road on 5 March 2020 by Sandra Chia.

Beginning on 11 March 2020, visitors to the Bishan-Ang Mo Kio Park stumbled upon a Mangrove Pitta, Pitta macrorhyncha. First reported by Steve Ang a day after, the bird continued to be reported until 30 March 2020 by Vincent Chin.  This bird represents one of the few rare occurrences on mainland Singapore’s non-mangrove habitats, previous records included one at Singapore Botanic Gardens and two at the Lower Peirce Reservoir boardwalk in 2014, and a recent finding at Woodlands in January 2020. During this period, visitors also reported two Asian Palm Swift, Cypsiurus balasiensis, on 11 March 2020 (Martin Kennewell). An Eastern Crowned Warbler, Phylloscopus coronatus, was also seen on 28 March 2020 by Angela Christine Chua. At Toa Payoh,  an Eastern Barn Owl, Tyto javanica, was reported on 16 March 2020 by Norman Wu.

Northern Singapore

A Black-capped Kingfisher, Halcyon pileata, was reported on 8 March 2020 from 960 Woodlands Road by Geri Lim, while a Jerdon’s Baza, Aviceda jerdoni, was reported on 21 March 2020 from Coney Island by Tan Kok Hui.

Eastern Singapore

Beginning with Kranji Marshes, we received sighting reports of eight White-shouldered Starling, Sturnia sinensis, on 7 March 2020 from Lau Jia Sheng. Also seen were two Grey-faced Buzzard, Butastur indicus, and a single Red Avadavat, Amandava amandava, on 8 March 2020 by Martti Siponen, who also spotted two Common Moorhen, Gallinula chloropus, on 21 March 2020. One Blue-winged Pitta, Pitta moluccensis, was seen on 29 March 2020, as was an Ashy Minivet, Pericrocotus divaricatus, by Martin Kennewell.

Over at the monsoon drain running somewhat parallel to Lim Chu Kang Lane 3, one Little Ringed Plover, Charadrius dubius, and a White Wagtail, Motacilla alba, were spotted on 23 March 2020 by Raghav Narayanswamy, who also spotted a Greater Painted-Snipe, Rostratula benghalensis, on 27 March 2020. A Ruddy Kingfisher, Halcyon coromanda, which was earlier reported at the site in January and February 2020, continued to be seen on 8 March 2020 by Vincent Chang and on 29 March 2020 by Michael Leong.

Along the fields at Neo Tiew Harvest Lane, a Watercock, Gallicrex cinerea, was spotted on 14 March 2020 by Martin Kennewell, while a Long-toed Stint, Calidris subminuta, was reported on 15 March 2020 by Russell Boyman. Several days later, two Oriental Pratincole, Glareola maldivarum, were reported on 27 March 2020 by Raghav Narayanswamy. At the nearby Sungei Buloh Wetland Reserve, a  Black Baza, Aviceda leuphotes, was spotted on 28 March 2020 by Martti Siponen, while the resident Copper-throated Sunbird, Leptocoma calcostetha, was observed on 30 March 2020 by Peter Bijlmakers.

The Brahminy Starling, Sturnia pagodarum, at Jurong Lake Garden continued to be seen, with a record on 1 March 2020 by Art Toh. Apart from the afore mentioned Asian Emerald Cuckoo on 23 March 2020, we also noted reports of a Thick-billed Green Pigeon, Treron curvirostra at King Albert Park by Martin Kennewell, as well as a  Greater Coucal, Centropus sinensis, on the same day at Ulu Pandan Park Connector by Oliver Tan. Two days later, an Ashy Drongo, Dicrurus leucophaeus, was reported from Ulu Pandan Park Connector as well, by Sylvester Goh.

2017 Year in Review. Part 2. Other Visitors.

The discovery of the Asian Emerald Cuckoo Chrysococcyx maculatus at Sentosa by Tuck Loong and Esther Ong on 23 December had to be one of the birding highlights of the year. Another was the sighting of a female Narcissus Flycatcher Ficedula narcissina that stopped over for 3 days at Dairy Farm NP on 28 November by Veronica Foo and Marcel Finlay. Two sightings of the vagrant White-throated Needletails Hirundapus caudacutus over the Henderson Wave on 19 and 31 Oct by Keita Sin and one over Jelutong Tower on 25 Oct by Francis Yap ( Cover photo). The cuckoo and flycatcher were only our second records for these species, while the needletails were our second, third and fourth records.


Asian Emerald Cuckoo feeding on Tussock Moth caterpillars at Sentosa was                      only our second record.

Other rare visitors include the Asian House Martins Delichon dasypus, seen thrice, 11 March at Kranji Marshes by Martin Kennewell, 19 October at Henderson Wave by Keita Sin and 24 November over Jelutong Tower by Francis Yap. Two Yellow-browed Warblers Phylloscopus inornatus, one at the Bukit Timah Hill summit on 18 January by Francis Yap and the other at Sentosa on 24 November by Lim Kim Chuah. A Siberian Thrush Geokichla sibirica was photographed by Khong Yew at Dairy Farm on 25 November and a Himalayan Cuckoo Cuculus saturatus on 3 January at Pulau Ubin’s Butterfly Hill by Keita Sin. A ‘summer visitor’, the Austral Horsfield’s Bronze Cuckoo Chrysococcyx basalis duly arrived on 27 May at Seletar end when Francis Yap went to look for them.

A good number of rare and endangered flycatchers were sighted during the year. The globally threatened Brown-chested Jungle Flycatcher Cyornis brunneatus was recorded at Jurong Island and even Sungei Buloh WR and its usual haunt Bidadari between 30 September and 7 November. The non-breeding Brown-streaked Flycatchers Muscicapa williamsoni came over between August 13-26 and were spotted at Pasir Ris Park, Jelutong Tower and Portsdown Road.

Laurence Eu gave us an early arriving Green-backed Flycatcher Ficedula elisae when he photographed one at Dempsey Hill on 7 September, 10 days ahead of the previous extreme date. There were five more sightings of this flycatcher all at the Central Catchment Forest up to 6 April. Low Choon How had a new late departure date for the Japanese Paradise Flycatcher Terpsiphone atrocaudata on 3 April at Simei. Other sightings of this flycatcher was at Belayer Creek on 24 October by Laurence Eu and a female bird at Bidadari on 12 and 18 November. Rounding up was the Zappey’s Flycatcher Cyanoptila cumatilis, a recent split from the Blue and White. A first-winter bird was photographed by Khong Yew at Dairy Farm NP on 21 November, with Dave Bakewell providing the identification.

Singapore Bird Report – December 2017

Singapore Bird Report-December 2017

The birding community could not ask for a better ending for the year. A national first (pending review by Record’s Committee), a second record after 11 years and several rare winter visitors gave many of us our year end lifers.

BW Fadhil

First photo of the “Booted Warbler” taken on 4th by Muhd Fadhil of NParks. 

Martin Kennewell was quick to alert us on an odd looking tree warbler at Kranji Marshes on 9th. After much consultation with overseas friends, the consensus is a Booted Warbler Iduna caligata, a long way from its wintering grounds in India and Sri Lanka. Muhd. Fadhil, an Nparks staff first photographed it on 4th. It is still there during the first week of January. Our thanks to Martin and Fadhil. 

Esther Ong

The photo that started the frenzy. Esther Ong’s photo of the Asian Emerald Cuckoo taken on 23rd December. 

While looking for the Chinese Hwamei Garrulax canorus, at Sentosa’s Siloso Park on 23th, Tuck Loong, Esther Ong and friends spotted a female Asian Emerald Cuckoo Chrysococcyx maculatus, feeding on the caterpillars on a bare Ficus superba there. Our first record for this non-breeding visitor was on 31 May 2006 at Seletar Reservoir Park. Incredibly a second female was reported six days later at the same tree feeding together. It stayed until 3rd January when all the caterpillars were gone, long enough for all of us to add a national tick to our list. A rare Yellow-browed Warbler Phylloscopus inornatus was also spotted there on 23rd (Lim Kim Chuah & Seng Beng) and along the Skywalk in following days.

Choon How

The month started with a rufous morph Oriental Scops Owl Otus sunia returning to the same tree at DFNP on 1st. Another, a grey morph also returned on the 9th (Luke Milo Teo). Earlier in the year, on 10th Jan 2017, both of them were seen on the same tree there, a case of site fidelity assuming they were the same owls. Lena Chow got a first for Bukit Batok with a sighting of a Grey Nightjar Caprimulgus jotaka, there on 1st. Another Grey Nightjar was back at Bidadari on 17th (Tan Kok Hui). At least 5 Eastern-crowned Warblers Phylloscopus coronatus, were counted at Upper Peirce Reservoir on 14th by Veronica Foo. An uncommon Black Drongo Dicrurus macrocercus, was videoed at PRP on 20th by Marc Ng.

Several rare flycatchers were still stopping over this month. Two Ferruginous Flycatchers Muscicapa ferruginea at DFNP on 1st (Oliver Tan), with another on 28th at RRL (Goh Cheng Teng and Lester Tan), our third of the season, a Japanese Paradise Flycatcher Terpsiphone atrocaudata at Lower Peirce Reservoir on 5th (Basil Chia), a dead Blue and White/ Zappey’s from SGH on 13th (David Tan) and another 1st winter Blue and White Cyanoptila cyanomelana, male at Siloso on 30th (Tan Kok Hui and Co), the rare Green-backed Ficedula elisae, at CCNR on 5th (David Gibson) and a female at RRL on 23th (Alan OwYong and Lim Kim Keang), ending with a Mugimaki Ficedula mugimaki, at Siloso on 27th by Martin Kennewell.

The cuckoos made a great showing this month in part due to the caterpillars on the bare ficus at Sentosa. Spotted there were 2 Chestnut-winged Cuckoos Clamator coromandus, one adult and one juvenile Indian Cuckoo Cuculus micropterus, one juvenile and one adult Large Hawk Cuckoo Hierococcyx sparverioides, a Malaysian Hawk-cuckoo Hierococcyx fugax and a Hodgson’s Hawk-cuckoo Hierococcyx nisicolor. A Hodgon’s was also photographed at Bishan Park on 8th by Terence Tan, a Malaysian Hawk-cuckoo at Healing Gardens on 14th by Laurence Eu, a dead Indian Cuckoo at NUS on 29th found by Yong Ding Li and a wintering Chestnut-winged Cuckoo at the SBG.

Notable shorebirds for the month include 2 globally threatened Great  Knot Calidris tenuirostris, at Chek Jawa on 6th (Lim Kim Keang) and Long-toed Stint Calidris subminuta, at Tekong on 23rd (Frankie Cheong).

Resident species of interest include Plume-toed Swiftets Collocalia affinis and Asian Palm Swift Cypsiurus balasiensis, at SBG on 5th by See Toh Yew Wai and 8th by Zacc respectively, a juvenile Black-crowned Night Heron Nycticorax nycticorax at Eco Lake on 9th by Martin Kennewell, Greater Coucal Centropus sinensis at Telok Blangah Walkway on 12th by James Tann and a White-rumped Munia Lonchura striatabelow KRP canopy walk on 15th by Marc Ng. Its wild status is in question.

An uncommon Cinnamon Bittern Ixobrychus cinnamomeus was spotted at SBTB by Tan Eng Boo on 19th. On the same day, Lim Kim Seng came across the long introduced Chinese Hwamei at Sentosa. It went missing for a large part of the year. The Oriental Darter Anhinga melanogaster at Pekan Quarry at Pulau Ubin picked out by Deborah Friets on 26th ends this report. Happy New Year and Good Birding 2018!                             

PS. A late record from Thio Hui Bing of another Oriental Darter seen at the Singapore Quarry on the 26 Dec suggested that there were two birds here. It is also the first for that location.

A Christmas Cuckoo Present

A Christmas Cuckoo Present by Alan OwYong and Yong Ding Li.

Lim Kim Seng reported the sighting of the Chinese Hwamei at Siloso on the 19th December.  There has been no reports of this naturalised laughingthrush for a good part of the year. This led to Tuck Loong, Esther Ong and others to go and look for it on 23rd December.

They not only got the Chinese Hwamei but hit the jackpot when Tuck Loong spotted a small cuckoo perched high up on a high bare tree. From some of the early photographs taken, it looked like a possible candidate for a female Asian Emerald Cuckoo Chrysococcyx maculatus.



Our Christmas present the female Asian Emerald Cuckoo turning up at Sentosa on 23rd December. 

Subsequent photographs obtained the next day confirmed their finding, effectively giving the whole birding community a timely Christmas present. All those who made the trip to the Siloso Skywalk over the following week went home happy with their tick.


Ticking our presents, all the happy birders and photographers at Siloso Skywalk on Christmas Eve.

The bare tree in question is the Deciduous Fig Ficus superba, a fig species known to shed its leaves periodically. When the new shoots and leaves started to sprout, the Tussock Moths presumably the Clearwing, Perina sunda took full advantage of this by laying thousands of eggs on the tree. The result was an outbreak of it’s caterpillars. There were so many caterpillars that large congregations of them were to be seen on the ground, railings and nearby structures.


The caterpillars of the Tussock Moths on the Ficus Superba attracted five species of cuckoos, an occurrence we  not witnessed before. 

It was this massive supply of food in the form of tussock moth caterpillars that attracted the cuckoos. The Asian Emerald Cuckoo, a rare migrant to the Malay Peninsula, naturally caused the most excitement as this would otherwise be the second record of the species for Singapore.  Another female cuckoo was sighted on the 29th December, and concurrent observations of both individuals confirmed that there were at least two Asian Emerald Cuckoos around, which is unprecedented! Other cuckoos partaking in this caterpillar feast included at least two Large Hawk Cuckoos, two Indian Cuckoos, two Chestnut-winged Cuckoos, and one Hodgson’s and Malaysian Hawk Cuckoo each. Other uncommon migratory birds seen in the secondary forest around the site included a Crow-billed Drongo, at least two Yellow-browed Warblers and a first winter male Blue-and-white/Zappey’s Flycatcher (Cyanoptila sp.).

Our first record of the Asian Emerald Cuckoo was a sub-adult female and juvenile observed at Seletar Reservoir Park on 31st May 2006. K.C. Tsang was the one who photographed them. Some of the diagnostic features were unclear in the photographs which resulted in conflicting identification answers from regional bird experts even after some consultation. The deliberations and discussions at the Records Committee went back and forth for two years before it was eventually included in the official NSS Checklist as a national first. There were two earlier records of females, both were turned out to be mis-identified Violet Cuckoos.

The Asian Emerald Cuckoo is widely distributed across the lower hills of the Himalayas (where it occurs as a summer visitor), eastward to southern China (Yunnan north to Sichuan) and much of continental Southeast Asia. There are few records in the Malay Peninsula and elsewhere in the Greater Sundas (e.g. Sumatra) where it probable occurs as a rare non-breeding visitor during the months of the northern winter.
