Singapore Raptor Report – December 2017

OHB, 081217, Sgp, Teo Chee Kee

Oriental Honey Buzzard, adult female dark morph, on 8 Dec 2017, by Teo Chee Kee.

Summary for migrant species:

December marked the arrival of two migrant raptor species. The first Eastern Marsh Harrier for the season, a juvenile, was photographed in flight at Kranji Marshes on the 2nd at 6:59am. This is fairly typical behaviour for the species as they are early movers. The first Black Kites of the season came in a group of three over Pulau Ubin on the 26th. The three juveniles were flying about over Pulau Sekudu and the nearby fish farms, probably hoping to scavenge.

The rufous morph Oriental Scops Owl found on 30 November at Dairy Farm Nature Park was still around on the 1st, but disappeared thereafter. On the 9th, a grey morph Oriental Scops Owl was found roosting high up a nearby tree; it was recorded again on the 11th and the 17th at the same locality. This grey morph individual might also have been the same one found in January this year, returning to the same locality in Singapore after breeding in the northern latitudes!

Three Jerdon’s Bazas were recorded. One frequented the Tampines Eco Green to Pasir Ris Park area throughout the month; another was recorded at Ang Mo Kio Town Garden West on the 10th and 11th; and the last one flew by Jelutong Tower on the 22nd. Two Common Buzzards were recorded; the first was photographed on the 2nd at Seletar Aerospace Drive; on the 6th, 2 birds were photographed at nearby Seletar West, and one of the birds may have been the same bird first recorded on the 2nd.

Five Chinese Sparrowhawks were recorded. A male at Pasir Ris Park on the 3rd and 9th; a female at Ang Mo Kio Town Garden West on the 9th, two over Henderson Wave on the 20th, and a female at Sentosa on the 24th. Two Peregrine Falcons were recorded; one at Clementi and the other at Seletar Airport area. Three Western Ospreys were recorded; one at SBWR-Kranji Marshes area, another at Yishun Dam and the last at Pasir Ris Park.

Finally, we come to the most abundant migrant raptors. 19 Japanese Sparrowhawks were recorded; a number of them at Henderson Waves, probably just passing through for destinations further south. 20 Black Bazas were recorded, and a small group is probably wintering at Pasir Ris Park. The Oriental Honey Buzzard is tops again with 93 birds; a number were recorded at Henderson wave, also probably just passing through on their way farther south.

Crested Goshawk (Accipiter Trivirgatus), 281217, Sentosa, Michael Phua

Crested Goshawks mating, at Sentosa, on 28 Dec 2017, by Michael Phua.

Highlights for sedentary species:

For the uncommon Crested Goshawk, 11 birds were recorded. Notably the pair at Sentosa was observed mating on four days: the 24th, 25th, 26th and 28th. The pair was observed bringing small branches to reinforce their nest high up the bare tree and on the 25th, the female goshawk was photographed breaking a small branch with its beak. A juvenile goshawk, probably from the pair’s last breeding attempt, was also seen at the tree on the 24th.

All three records of the torquatus Oriental Honey Buzzards were of the tweeddale form. An adult male was recorded at Pasir Ris Park on the 15th, the record on the 21st was probably of the same individual. Another was recorded at Toa Payoh on the 17th.

Of the two Grey-headed Fish Eagles recorded, one was at Bishan Park and the other at Little Guilin, where a new nest had been built on a tall tree but nesting was not observed during the month. The other resident raptors recorded included the Changeable Hawk Eagle, Brahminy Kite and White-bellied Sea Eagle.

Personal Observations of the Plovers at Marina East Drive.

By Dr. Pary Sivaraman.

These are my own personal observations on the 17th and 18th January 2018 at Marina East Drive. Similar observations on both dates and I was the only birder on both dates.

There was a group of about 10 to 12 Swinhoe’s or White faced Plovers, ssp. dealbatus. Some were in breeding plumage. Just beside them but as a separate group there were about 15 to 16 Kentish Plovers, Charadrius alexandrinus. Some were in breeding plumage. On the first date, the Kentish Plovers were closer to me. On the second date the White faced Plovers were closer to me.

The groups tolerated a certain distance between me and them.
When I moved closer they would start walking a few feet.
If I continued, they would fly but interestingly the group closer to me would fly off first.
On the first date, the Kentish Plovers flew off first but the White faced Plovers moved a couple steps further from me and stayed.

On the second date, the White faced Plovers behaved similarly. They were closer and flew off first. The Kentish Plovers didn’t fly off but moved a couple of steps further from me and stayed.

Swinhoe’s or White-faced Plover in breeding plumage.

I thought it was interesting since the White faced Plovers or Kentish Plovers seemed to stick together as a group. I must emphasize I didn’t move too quickly to them. I presume if I did all of them would have flown away.

I have attached the photos of the Kentish and White faced Plovers in breeding plumage.
I have taken more photos for my own understanding how the birds.

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.

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.

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.

Raptor Migration ( Autumn) along Henderson Waves

Raptor Migration (Autumn) along Henderson Waves

Article and photos by Keita Sin

Autumn migration

Birdwatching in Singapore gets particularly exciting during the migratory season. One of the groups of birds that migrate through Singapore is what are generally referred to as “raptors” – birds of prey from the order Accipitriformes (eagles, hawks, harriers etc) and Falconiformes (falcon, kestrels etc).

The majority of raptors migrate through Singapore around October to November for the autumn migration, during which they head south to their wintering grounds. During the spring migration in mid-February to mid-April, they will head back north towards their breeding grounds.

There are several locations that have been known to be good spots for raptor watching in autumn. The annual Singapore Bird Group Raptor Count has been conducted at these locations, such as Pulau Ubin, Changi, Tuas and the Southern Ridges (Kent Ridge Park and Telok Blangah Hill Park).

Being a fan of raptors myself, I joined the Raptor Counts at Kent Ridge Park in 2015 and 2016 to watch the convoys of birds flying south-east along the ridge. During these counts, one particular question occurred to me: if the birds were filtering in at different points on the Southern Ridges before continuing to fly along the ridge, wouldn’t it be most productive to do a count as close as possible to its southernmost end?

The birds of Henderson Waves

On 17th November 2016, I made my way towards Mount Faber Park (the southernmost park along the ridge) to find out the answers to my question. However, the views offered there were rather disappointing, and I thus continued towards the Henderson Waves, which offered great views in all directions.

Photo 1 View from HWView from Henderson Waves (facing South)

I stood there from 9:20am to 1:00pm and was rewarded with 19 Crested Honey Buzzards; 9 Black Bazas; 1 Booted Eagle; 1 Chinese Sparrowhawk; 8 Japanese Sparrowhawks; and most importantly, 1 Eurasian Sparrowhawk, which then became the second accepted record for Singapore.

Observations in 2016 and 2017 by many pairs of eyes led to observations of many other uncommon migratory raptors including the Greater Spotted Eagle, Grey-faced Buzzard, Common Buzzard and Jerdon’s Baza. Other migratory raptors such as the Pied Harrier and Eastern Marsh-harrier were recorded nearby too. Resident raptors such as the Crested Goshawk, Changeable Hawk-eagle, Crested Serpent Eagle and Grey-headed Fish-eagle were also seen regularly (detailed counts in the monthly raptor report).

Other migrants such as Oriental Pratincoles, Pacific Swifts, Barn and Red-rumped Swallows, Ashy Minivets, and Blue-throated and Blue-tailed Bee-eaters regularly flew over the bridge too.

The highlights, however, were the Asian House Martin (solitary bird on 19 October) and Needletails. The second and fourth White-throated Needletails in Singapore were recorded (a solitary bird on 19 October, and another on 31 October flying together with 2 other unidentified needletails) and another single unidentified Needletail was photographed on 6 November (by Lawrence Cher).

Photo 5 White-throated NeedletailWhite-throated Needletail at Henderson Waves, 31 October 2017

The diversity of birds recorded at Henderson Waves is astonishing compared to the other sites along the Southern Ridges. It could be that many of the birds flew south through the Central Catchment and only entered the ridge halfway through, causing them to be unrecorded at the other locations. The better view offered at the bridge might also have contributed to the increased diversity observed.

The raptors (and other migrants) usually fly over the bridge from north-west to south-east (from Telok Blangah Hill Park towards Mount Faber Park). The collective observation of the large number of birders stationed at the bridge in 2017 seems to point to a rough trend of having better counts (in terms of both quantity and diversity) when the wind is blowing from the north-west direction.

Birding at Henderson Waves

On text, Henderson Waves sounds like the perfect place in Singapore to go raptor watching. It is, sadly, not as fantastic as it seems. This place offers no shelter from the scorching sun (and yet the hotter it is, the better for raptor migration) and the birds tend to fly very high along the ridge. For those whose main objective is bird photography, Henderson Waves will be a disappointment. However those who are prepared can be rewarded with beautiful sights of convoys of birds, and the occasional low-flying raptor. Those who keep local lists will no doubt be able to tick off a great number of uncommon species.

When birding at Henderson Waves, make sure you protect yourself against the sun – apply sunblock, wear a hat, and put on sunglasses. It will also be great to record the wind direction and share your sightings. A pair of binoculars is a must.

What about spring migration?

Singapore has a lower number (in terms of both quantity and diversity) of raptors recorded during the spring migration. This could be due to the different flight paths taken by the raptors during their return journey, and it would be interesting to find out how Henderson Waves performs then. Could there be a different site in Singapore that hosts the main bulk of raptors flying through in spring? There’s only one way to find out.

The 14th Fall Migration Bird Census

The 14th Fall Migration Bird Census by Lim Kim Chuah

The 14th Fall Migration Bird Census (FMBC) took place in the morning of 22nd October 2017. 58 counters took part and 26 sites were counted. Weather was quite variable throughout the sites surveyed ranging from partly cloudy and overcast to sunny. It rained in some places towards the end of the count.

In all, 138 species totaling 5,306 birds were counted. The total number of birds counted was disappointing and the number was the lowest counted in the 14-year history of the FMBC.

On a brighter note, this census shows that Singapore remains an important stronghold for the vulnerable Straw-headed Bulbul. 49 birds were counted with more than half from Pulau Ubin. Pulau Ubin also proves to be an important site for another globally threatened species, the White-rumped Shama with most of the 16 birds counted coming from Pulau Ubin.

34 species of true migrants were counted totaling 1019 birds. This represents 35% of total species counted and 19% of total number of birds counted.

TOTAL BIRDS AND SPECIES COUNTED

In all, 138 species of birds were recorded consisting of 5,306 birds. If unidentified birds (including swiftlets) are added, the total was 5810 birds.

In terms of species, the total of 138 species was close to the 14-year average of 135. However, the total birds counted of 5,306 (compared to the average of 7,226) was the lowest recorded in the 14-year history of FMBC. Also noted was the disturbing decreasing trend of birds counted during the last two editions of the census – 5,416 in 2015 and 5,314 in 2016 (see chart).

1-26540525_1557845491002753_1887872684_o
One of the possible reasons for the low number counted this year could be the big drop in the number of birds counted in one of the key wader sites, Sungei Mandai. Only 316 birds were counted compared to the average of 1,138. One possible reason is that most of the mudflat at Sungei Mandai was covered by algae and this probably limit the amount of mudflat for the waders to forage.

1-26513643_1557845451002757_8373827_o
TOP 20 BIRDS

The top spot for the most number of birds counted went to the Asian Glossy Starling (663) and this was closely followed by the Javan Myna (645). Whimbrel was the most numerous migrant counted.

The top bird counted for 2016, the Lesser Sand Plover was conspicuously absent from the top 20 birds. Only 3 birds were counted during the census. Another observation is the notable decrease in the number of Pacific Golden Plover counted, falling from position 4 (364 birds) last year to 18 (63 birds). Pacific Golden Plover is typically featured among the top 10 birds in most years (see chart). The chart also shows a decreasing trend since 2004.

SITE COUNTS

A total of 26 sites were surveyed. This is comparable to the 14-year average of 25 sites.

The site with the most number of birds counted was Pasir Ris Park with 406 birds counted. This is closely followed by Sungei Buloh Wetland Reserve Route 1 (394) and Sungei Buloh Wetland Reserve Route 2 (389).

1-26510800_1557845467669422_1844015155_o

The diversity of habitats at Kranji Marsh, Kranji Dam and Pasir Ris Park prove to be attractive for many species of birds and these three sites ended with the most number of bird species recorded. Kranji Marsh took top spot with a whopping 76 species, followed by Kranji Dam (51 species) and Pasir Ris Park (48 species).

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.
