Summary:

Only four migrant raptor species were recorded in the April to June period. They are the regulars during this period – the Western Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon.

There were eleven records of the Oriental Honey Buzzard Pernis ptilorhyncus in April, ten in May and eight in June. At least five records in April were orientalis juveniles, as were six in May and four in June – these birds are spending the summer here in the tropics.

Five Japanese Sparrowhawks Accipiter gularis were recorded between 1-12 April. Singles at Ulu Pandan on 1st April, Mount Faber on 5th April, Pulau Ubin on 7th April, and Dairy Farm Nature Park on 8th April & 12th April. These are the last birds to leave for their breeding grounds to the north.

Seven Peregrine Falcons Falco peregrinus were recorded, all in the month of April. Notably, the individual photographed at Toa Payoh on 17th April had, on its left tarsus (leg), a ring with ‘JBP’ engraved. This bird was rescued, rehabilitated and released by the Jurong Bird Park (JBP) more than ten years ago. Another individual recorded at Haig Road on 4th April was mobbing an Oriental Honey Buzzard.

Five Western Ospreys Pandion haliaetus were recorded in the April-June period. Two at the Krani – Sungei Buloh area throughout, one at Gardens by the Bay on 3rd April, one at Jurong Lake on 27th April, and one at Pulau Ubin – Pasir Ris area on 22nd April and 8th May.

Sedentary Raptors

The Changeable Hawk-Eagle Nisaetus cirrhatus was reported to be nesting at Kranji Marsh area on 19th April, and the White-bellied Sea Eagle Haliaeetus leucogaster was also nesting at Fort Canning, with a well grown chick on the nest observed between 13-29 June. Juveniles of the Crested Goshawk Accipiter trivirgatus at Bishan (April), Pasir Ris (April – 2 birds), and Ang Mo Kio (May), and a fresh juvenile Changeable Hawk-Eagle at Pasir Ris (April & May) suggest that breeding had occurred in the preceding months.

A nest, presumably that of the Brahminy Kite Haliastur Indus, based on the size of the nest and the observer’s experience, was recorded at the Rail Corridor near Phoenix Heights on 27th June. Also, a pair (a male & a female) of adult Crested Goshawks was recorded at South Buona Vista Road on 13th June, as were two adult Grey-headed Fish Eagles Haliaeetus ichthyaetus, probably a pair, at Sungei Ulu Pandan, also on 13th June.

One Crested Serpent Eagle Spilornis cheela was present at Goldhill Avenue area in April and May, with the exception of 27th April when two birds were seen. In addition, one individual was recorded at Pulau Ubin (April & May), one at Toh Tuck Road (25th May), and one at Sentosa on 10th & 15th April. An adult Peregrine Falcon of the resident ernesti race was photographed at Jurong East on 2nd June, perched on a TV antenna consuming a bird.

Nocturnal Raptors

A family of Spotted Wood Owls Strix seloputo comprising two adults and a recently fledged chick was recorded at Cashew Road on 1st May, the nesting was first noted in March and the chick had fallen from the nest during the nesting period, but all was well after intervention by ACRES. On 9th June, a family of Buffy Fish Owls Ketupa ketupu, including a recently fledged juvenile, was photographed at Jurong Lake. As an indication of another successful nesting attempt, a juvenile Barred Eagle-Owl Bubo sumatranus was photographed at Bukit Timah on 28th June. Notably, a Barred Eagle-Owl was recorded at Bukit Brown, a new locality for the species, on 27th April.

Singapore Bird Report – June 2019

by Geoff Lim, & Tan Gim Cheong (ed.)

Resident species dominate this month’s report. Of note is the report of 11 newly hatched Lesser Whistling Duck at Gardens by the Bay, the preponderance of forest species at Dairy Farm Nature Park, as well as the stars of Pulau Ubin – the Buff-rumped Woodpecker, Mangrove Pitta and the Black-winged Flycatcher-Shrike.

Central Catchment Nature Reserve (CCNR) & DFNP

The bulk of sightings in this area took place at Dairy Farm Nature Park (DFNP) as birds were drawn to several fruiting mulberry and false curry leaf trees near Wallace Centre. Between 3 and 22 June 2019, a variety of forest species were spotted:

  • A Common Emerald Dove Chalcophaps indica was spotted on 22 June by Saravanan Krishnamurthy;
CED, Saran

  • Both species of Barbets were observed. The resident Red-crowned Barbet Megalaima rafflesii and introduced Lineated Barbet Megalaima lineata were spotted on 7 June by Terence Tan. The Lineated Barbet sighted was a juvenile;
  • A Banded Woodpecker Chrysophlegma miniaceum was spotted on 7 June by Terence Tan;
  • Both trees attracted the Black-crested Bulbul Pycnonotus flaviventris, which is more commonly seen at the summit of Bukit Timah Hill, from 2 to 10 June by various observers such as Siew Mun, Dean Tan, Raymond Bong, Terence Tan and Steven Lee, the Cream-vented Bulbul Pycnonotus simplex on 8 June by Yong Ding Li and Geoff Lim, and the Asian Red-eyed Bulbul Pycnonotus brunneus on 5 June by Betty Shaw and 7 June by Peter Lim, who also spotted the critically endangered Straw-headed Bulbul Pycnonotus zeylanicus (BirdLife 2018) on 6 June;

  • Two species of Leafbirds were observed. A female Greater Green Leafbird Chloropsis sonnerati was seen on 5 June by Betty Shaw and Terence Tan feeding on the false curry leaf tree, and a male on 8 June by Yang Chee Meng. This species occurs in lower densities. Currently listed as being Vulnerable (Birdlife 2016), the bird’s singing abilities have made it a target of songbird poachers in Indonesia (Chng et al, 2017). The more colourful Blue-winged Leafbird Chloropsis cochinchinensis was spotted on 4 June and 10 June (male) by Desmond Yap, 11 June (male) by Vincent Chin and 16 June (male) by Angela Yeo. All sightings involved the bird feeding on a mulberry tree.

Nest Building by a pair of Chestnut-winged Babblers in Singapore.

Nest building by a pair of Chestnut-winged Babblers in Singapore.

By Alan OwYong

  1. Introduction:

The Chestnut-winged Babbler Stachyris erythroptera is an uncommon breeding resident found in thick vegetation along the forest edges within the Central Catchment Forest in Singapore (Lim and Gardner 1997). It is the last surviving representative of its genus Stachyris in Singapore. The subspecies in Singapore is erythroptera (Gibson-Hill 1950). They are listed as nationally threatened due to their small, highly localised population. Breeding has previously been recorded at Nee Soon and Sime Road forests in 1987. More recently, courtship and nesting had been reported in 2007.  Its global range includes Southern Thailand, Peninsular Malaysia, Sumatra and the island of Borneo.

Laurence Eu’s photo of the Chestnut-winged Babbler building the first nest in the open.

  1. Finding the first nest:

On 13 May 2018, Laurence Eu came across a pair of Chestnut-winged Babblers flitting around the base of a clump of dry vegetation by the side of the track at the Sime Forest. He saw them going in and out with some twigs and leaves close to the ground. They were clearly building a nest.

1-20180514_120820

The nest that Laurence first came across was among the tangled mass in the middle of the photo almost at ground level.

He went back the next morning but the babblers were not around. They seemed to have abandoned this nest, which was just a few metres off the track. I met up with him later. We then came across a pair of babblers moving around behind some thick foliage not too far from the old nest.

3. Finding the second nest:

Our guess was that they were the same pair and were building another nest. The Chestnut-winged Babblers were known to abandon nests and rebuild if they feel that a particular location is unsuitable. We were right. Both of them were bringing back dry rattan (Calamus sp) leaves to an untidy hanging clump of vines and dead leaves. It seems that they preferred longish leaves as the main nesting material. This time the nest was at mid storey but still close to (about 2 metres) the walking track.

Sitting sluggly in the nest

Side view of early nest building in progress, wiggling to press their preferred longish leaves down.

An earlier Chestnut-winged Babbler’s nest I came across in the forests around Gunung Panti in Johor on 30 July 2017 was also built with broad leaves as well. There are also photos in the internet showing them bringing back bamboo leaves to build their nests.

Both parents are involved in the nest building

Both parents were actively involved in nest building often competing with each other in bringing back the leaves.

4. Building the second nest:

Both birds were actively involved in the nest building, often bringing back the leaves at the same time. The nest was round, about 20 cm wide, made out of a cluster of dry leaves and twigs, attached to an intertwined mass of leaves and thin branches. The entrance is just a small hole by the front side of the nest.

1-P5140751

The nest is a cluster of leaves and twigs intertwine among the dry mid storey hanging masses.

They must have just started nest building and did not appear bothered with our presence there. As the rattan plant was nearby, the pair were able to construct the nest quickly. After pushing a leaf in through the entrance hole, the bird would go inside the nest to place the leaf and line it up by wiggling its body before flying out again.

We were a little worried as the nest was very close to the track and associated human disturbance. We returned the next morning to check on their progress and hoped to see them using the nest. But alas it was not to be! Again they decided to abandon this nest as well. We checked to see if they were building another nest nearby but there was no sign of them. We did not hear any calls from them either for the rest of the morning. All the nesting records of this babbler that I have read online have the same ending of the nest being abandoned. The search goes on to find a stable nest to document and learn more of the nesting behaviour of these elusive forest babblers.

The nest inside the tangled mess near the top of the photo was only 2 meters away from the walking track.

Many thanks to Laurence for showing me the site and for the use of his photo and Albert Low for the editing.

Scaly-breasted Munia enjoying Algae.

Scaly-breasted Munia enjoying algae
 
by T.Ramesh 

Scaly-breasted Munias ( Lonchura punctulata) are common residents in Singapore and have two races  – the local fretensis with paler upper parts and the introduced topela with distinctive brownish upper parts.   The introduced species of topela are common along the grass patches of Changi Business Park (CBP) canal which is behind the CBP bus depot.

During one of my regular birding walk along this  canal recently,  I noticed a thick layer of green algae had bloomed on the canal.   Algae are plants lacking roots, stems and leaves and they are widespread in terms of habitats.  Singapore with equatorial climate has algal abundance and richness with 1054 species recorded .
I observed a Scaly-breasted Munia  landed on the algae.  Generally they are gregarious in groups but foraging can be individual or in group .  Studies have established the economic consequences of joining other munias in two models :  i) Information sharing model and ii) producer-scourger model .
However,  here it was alone . It poked the slimy algae and pulled the strands out to munch.  It kept hopping on different parts of the algae and continued to feed while alertly looking around for any threat . I quote below Avery, ML ‘s observation in his research paper in 1975 on White-rumped Munia’s feeding behaviour  in Malaysia:
 “Field observations and stomach analyses showed that the munias ate rice and the green filamentous alga, Spirogyra, almost exclusively. The primary periods of algae eating occurred in January and June-August, coinciding with the munias’ two peak periods of reproductive activity, as determined by gonadal examination. Apparently munias on the study area ate Spirogyra as a source of protein to enable them to become physiologically ready for breeding, much as other tropical bird species eat insects .”

 Though this behaviour is observed in other countries, glad to video record this in Singapore .

Nesting of Rufescent Prinias in Peninsular Malaysia.

Nesting of Rufescent Prinias in Peninsular Malaysia.

By Connie Khoo.

The Rufescent Prinia Prinia rufescens is a common breeding resident in Malaysia. The subspecies found in Peninsular Malaysia is extrema. It is one of the three Prinia species listed in Malaysia. It can be found in open scrub and dry grasslands next to forest edges. It is also a common resident across South East Asia except Central Thailand and Singapore. Its range include North and North East India, Bhutan and SW China.

On 3rd June 2019 I came across a low nest by the side of a forest outside Ipoh, Perak. The nest was built by stitching up the sides of a large leaf into a conical shaped cup just like a tailorbird’s nest. The one meter tall plant is identified as the Terung Asam, Solanum lasiocarpum, by my friend Amar-Singh HSS. It was lined with fine dried grasses inside and hung about a half meter above ground.

The nest is very similar to that of the tailorbird’s nest, leaf sewn together, cup shaped and filled with fine grasses inside.

Three hatchlings with pin feathers and exposed naked skin were seen inside the nest. Their eyes were closed. I estimated that they hatched no more than 2 to 3 day before.

When I visited the nest again on the 6th June, the parents were more relaxed and were feeding the chicks regularly. During the monitoring over the next few days, I saw the parents bringing back a variety of insects for the chicks with caterpillars as the main diet. Other insects include grasshoppers, small moths and butterflies, termites, spiders, black ants and insect eggs. However no dragonflies or damselflies were brought back.

On 8th June, the chicks were fully covered by feathers and their eyes were open. By now they were about 7-8 days old.

The first chick fledged on the morning of the 12th June at 8.38 am, 11-13 days after hatching. It jumped out of the nest and then flew to a thin branch 3 meters away. This caused much anxiety and excitement with the parents. The second and third chick followed suit at 8.46 am and 9.18 am. They flew straight to the nearest branch much to the relief of the parents. The feeding continued that morning but I was surprised to find two more adults coming by to help feed the chicks. This communal feeding was recorded in other species but this is the first time I have seen it with this prinia.

The first fledgling came out of the nest after 11-13 days after hatching.

The parents led the chicks out to the forest edges to feed the next day. By now it was hard to monitor them as the chicks moved deeper into the denser part of the forest.

I was glad to be able to document this nesting as past nesting failed either due to predation or inclement weather.
