Japanese Sparrowhawk, male, at Pasir Ris Park, 25 June 2017, a new and amazingly late date for the species, by Kozi Ichiyama.

Summary:

Four migrant raptor species were recorded in the April to June period. They were the Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon, all of which were also recorded during last year’s late spring migration.

The most amazing record must have been the Japanese Sparrowhawk photographed on 25th June at Pasir Ris Park by Kozi Ichiyama. This is a full month beyond the extreme date (25 May) in An Annotated Checklist of the Birds of Singapore and well beyond that in The Avifauna of Singapore (1 May). Elsewhere, singles of the Japanese Sparrowhawk were recorded at Bukit Timah and Kranji up to mid April, followed by 2 birds –  a male and a female – flying north at Punggol Barat on 16th April.

Of the 18 Oriental Honey Buzzards recorded, 1 was of the torquatus race and at least 12 were of the orientalis race. Of the orientalis race, 10 were juveniles or second calendar year birds – 4 of these young birds were recorded in April, 2 in May and 4 in June. There were also 2 adult orientalis in April. On 25 April, a young OHB was chased away from the tree where it had perched by a resident Grey-headed Fish Eagle. A single torquatus was recorded from April to June at the Bishan-Ang Mo Kio area.

A single Osprey was recorded at the Kranji-Sungei Buloh area from April to June, and another at Seletar in May. Two Peregrine Falcons were recorded, one at Church Street (migratory race) in April and another at Hindhede in May.

Sedentary Raptors

A Crested Serpent Eagle on 2nd April at Pulau Ubin was the only record of this rare raptor during this 3-month period. For the Grey-headed Fish Eagle, there were 3 at the Kranji-Sungei Buloh area, 2 at the Botanic Gardens, 2 at the Ubin-Changi area, 1 at Bukit Timah area and 1 at Jurong Lake. Small numbers (up to 3 together) of the Black-winged Kite were record at the Kranji-Sungei Buloh area and at the Punggol-Seletar area in all 3 months.

Two nestings of the White-bellied Sea Eagle were observed during this period, one at Pasir Ris (2 chicks) and another at West Coast Park (at least 1 chick). Elsewhere, this common raptor was observed in many areas, with up to 6 birds at any one time. For the Crested Goshawk, there was another successful nesting, with 2 chicks, at the Singapore Botanic Gardens during this 3-month period. Elsewhere, apart from 3 birds calling at West Coast Park on 1st June, all other records were mostly of single birds.

The common Brahminy Kite was recorded in all 3 months and a max of 18 was recorded at Kranji Marsh in April. For the uncommon Changeable Hawk Eagle, records were mostly singles, mainly from the Central Forest areas, Kranji-Sungei Buloh and Simpang Kiri-Punggol stretch. 

addendum to March Raptor Report
2 adults and 1 juvenile Grey-headed Fish Eagle, which was being fed, at Little Guilin was recorded on 27 March 2017 by Keita Sin.

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.

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.

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.

Aldwin Recinto chanced upon the lowly situated nest of the Yellow-bellied Prinia Prinia flaviventris at Lorong Halus on 17th. Two days later the chick fledged. A pair of over worked Common Ioras Aegithina tiphia were busy keeping up with the feeding of a Banded Bay Cuckoo Cacomantis sonnerati chick over at Jurong Eco Garden on 20th (Lee Chuin Ming).

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.

Oriental Pied Hornbills Nest Moving?

Contributed by Connie Khoo.

On 21st April 2017, I was birding around the limestone hills in Ipoh when I saw a pair of large birds, which I thought were eagles or owls, flying and landing on the cliff sides. But it turned out to be a pair of Oriental Pied Hornbills instead. When I zoomed in with my scope, I was shocked to see that the male was carrying an egg in its beak. It then carried the egg into a big cavity after the female had inspected it. They both came out after a short while and flew off together. I was thinking that they may have stolen some other bird’s egg and hiding it there as I have seen this pair on this side of the cliff before.

In less than 3 minutes, both flew back again with the male was carrying another egg in its beak. They are moving their nest! I was stunned! They were also surprised to find that someone was watching them moving their eggs to a “safer” place.

A week later on 28th, I saw the male holding a feather outside the nest for a while before flying off. The female was no where to be seen. While both were away Rock Pigeons, Asian Glossy Starlings, Eurasian Tree-sparrows and Jungle Mynas were hanging outside their nest.

On the 30th morning I went back to check on them. I saw the male flying back to the cavity alone calling loudly, rested for two minutes and then perched on a branch nearby. It later flew back to the “nest”, stay inside for a minute or two and flew off to the Durian plantation across the road. I thought that it may be carrying the eggs back to its previous nest but I cannot see any eggs in its beak.

I returned in May and June weekly to check on their progress, spending a few hours each time. Unfortunately they were not around anymore.  I cannot draw any conclusion from this observation except that they are removing its eggs from one nest to another place, which turned out to be a cliff cavity instead of a tree hole.

Alan Kemp’s commented:

How exciting!!! I have never heard of any hornbill removing its eggs from a nest and placing them in another cavity elsewhere, especially unexpected, except at the very start of incubation, since the female thereafter should begin her flight feather moult and so become flightless. I did received one unpublished report of this species very likely using a cavity in a limestone cliff in southern China for nesting (that I included in my 1995 book), and several other hornbill species, including Great Hornbill, have been reported nesting and sealing up cliff cavities. Obviously you will continue to watch your site to see if anything develops (although the cavity does to look a good one to try and seal), and it would be lucky if you could try and guess and/or find the original cavity from where the eggs were taken (and if it was in a tree or in another cliff site).

The eggs size and colour looks like it is their eggs, rather than from some other bird’s nest that they may have robbed. Even if they did rob it, I also know of no hornbill hiding food for later use (called ‘caching/ making a cache’ for raptors).

A third, even less likely, idea is that may be these two birds are helpers to a third that is in the cavity they visited, but that too seems unlikely if they both went in the hole together.

 

The Pasir Ris Pied Fantail Story

Contributed by Seng Alvin.

I have been watching the nesting of the Malayan Pied Fantails Rhipidura javanica at Pasir Ris Park since 2014. All have been successful and none were invaded by the cuckoos. There was single nesting in 2014 but two in 2015 and last year.

19667619_1401944123217714_531500128511659950_o

In January this year, a pair was again seen building a nest. By March two chicks were brought up successfully to grace the park. On 17th April I was a little surprised when I saw an adult bird sitting on the same old nest. They must have just bought this “resale unit” and moved in. I knew that they will be nesting again.

19402001_1401944313217695_3647856079902138388_o

But just as they were about to settle down, they decided to move to a “BTO” nest nearby. The poor father must have thought that he could take it easy this time round by reusing the old nest. It was not to be. He built a new nest around April/May just like any daddy would to please the mummy.

The new nest which look rather precarious.

Maybe it is the neighborhood, but sometime in early June I found the pair back at the old nest. It could be that the old nest is at a more convenient neighborhood close to the foraging grounds? It is still location, location, location even for the birds.

Back at the old nest in early June. 

After all the hard work, they raise only one chick this time round. This is for the better as they can bring this one chick up without much stress.

19511247_1401944589884334_8940549613624020334_n

Only one chick this time around, less stress for the parents.

On 29th June, the chick fledged. The decision to stop at one paid off. Unless we tagged the adult birds, we cannot be certain if this pair are the same as the earlier pair that make Pasir Ris Park their home. I am really glad that despite the number of park visitors roaming around, these fantails are able to adapt and thrive here.
