The autumn migration is truly underway this month with more passerines reported all over the island. Out of the twenty plus arrivals this month, only four beat their previous early arrival dates. Some like the Arctic Warblers were very late.
The list of the first arrivals of the season:

- Red-footed Booby Sula sula, a dried up carcass was found washed up on the seawall at Marina Barrage on 3rd by Adrian Silas Tay and friends. May have died at sea while on transit.

- Chinese Egret Egretta eulophotes, bird seen on the same day on Tekong by Frankie Cheong. Another three were reported there on 23rd and one on 29th. The reclaimed land there had been their favourite wintering ground for the past few years.
- A White-winged Tern Chlidonias leucopterus was reported by Adrian Silas Tay at Lorong Halus on 10th. Lim Kim Keang reported several White-winged Terns feeding at Serangoon Reservoir on 15th. White-winged Terns usually arrives much earlier in July and August.
- Adrian Silas Tay also had a Whiskered Tern Chlidonias hydrida, at the Lorong Halus that same day. This is about a week later than last year’s early date.
- Blue-winged Pitta Pitta moluccensis, one heard calling at the Bulim Woods on 10th by James Tann. It could be either an overstayer or a new arrival.
- Forest Wagtail Dendronanthus indicus, seen at the MacRitchie Trail on 10th by Marcel Finlay. This was followed by one at GBTB on 25th photographed by Terence Tan and another at DFNP by James Tann on 25th.
- Another Wagtail, this time an Eastern Yellow Wagtail Motacilla tschuschensis, from Kranji Sanctuary Golf Course on 10th by Fadzrun A.
- Martin Kennewell had an early Pin-tailed Snipe Gallinago stenura, at Kranji Marshes on the 10th. Identified by call, this individual is 5 days earlier than the previous arrival date.
- Red-necked Stint Calidris ruficollis first one reported at Seletar Dam on 8th by Marcel Finlay. The second, a juvenile made a late landfall at Marina Barrage on 13th, duly spotted by Robin Tan. This juvenile stayed over to refuel for more than 2 weeks. On 23rd, Frankie Cheong reported three more Red-necked Stints at Pulau Tekong.
- Kentish Plover Charadrius alexandrinus, two birds were photographed at the Marina Barrage on 15th by Robin Tan. Pary Sivaraman posted another photo of one of them he shot the next day. A subspecies, the Swinhoe’s Plover C.a. dealbatus, was identified by Dave Bakewell from photos taken there by Alan OwYong on the 15th.
- Amur Paradise Flycatcher Terpsiphone incei, a recent split, was photographed at Chinese Gardens on 20th by Siew Mun and seen by Marcel Finlay at Bukit Brown on same day. He had another at Old Thompson Road on 25th. Terence Tan also shot one at DFNP on 21st. Two birds were reported from Bidadari as well on 24th by Francis Yap and Alan OwYong. The Amur seems to be more commonly encountered than the Blyth’s during this migratory period.
- Drongo Cuckoo Surniculus lugubris, was photographed at the Japanese Gardens on 21st by Gerald Lim.
- A returning non-breeding visitor, Blue-tailed Bee-eater Merops philippinus, was photographed at Lorong Halus on 26th by Seng Alvin. This is just a day earlier than the last reported date. Alan OwYong saw the same bee-eater there the next day.
- Blue Rock Thrush Monticola solitarius, a male was a surprise find at Gardens East on 27th. It beats the earlier arrival date by 3 weeks. Unfortunately it did not stay around.
- Over at Pulau Ubin, a confiding Oriental Dwarf Kingfisher Ceyx erithaca, was spotted by See Toh Yew Wai, Francis Yap and friends on 23rd. Last year one crashed into the River Valley High School on the same day.
- A Brown Shrike Lanius cristatus, was first recorded at Bukit Brown on 20th b=y Marcel Finlay. A second arrived at Bidadari on 24th. Robin Tan was there to welcome it. The next day another was picked up by Terence Tan at GBTB.
- Pallas’s Grasshopper Warblers Locustella certhiola, are overdue. Great that Rama Krishnan heard one calling at the Kranji Marshes on 25th to confirm that they arrived. These confiding warblers are notoriously hard to see.
- Two Arctic Warblers Phylloscopus borealis, was reported by Tay Kian Guan on 21st at the Southern Ridges. Veronica Foo saw another at Hindhede NP on 28th. Unusually late as we get them in early August.
- Finally we had our first Brown-chested Jungle Flycatcher Cyornis brunneata, when Martin Kennewell photographed one at SBWR on the 30th. Previous early arrival date was 23rd September.
- Kozi Ichiyama recorded the first Yellow-rumped Flycatcher Ficedula zanthopygia, on the last day of August. It was the start of an influx of these flycatchers all over the island for the whole of September including our second casualty that crashed into a factory in the Joo Koon, Tuas area on 18th (David Tan).

Based on our previous pelagic trips, mid September was the height of the passage of the Swinhoe’s Storm Petrels Oceanadroma monorhis, and Bridled Terns Onychoprion anaethetus, with counts of 5-600 birds. Unfortunately the 17th September trip organised by the Bird Group for NSS members came back with very low counts for both (16 for Bridled and 18 for the Storm Petrels). But they did established new early arrival date for the 25 Aleutian Terns Onychoprion aleuticus. Other seabirds recorded by Alfred Chia, Lim Kim Keang, Lim Kin Seng, Con Foley and others were 25 Swift Terns Thalasseus bergii, 3 Lesser Crested Terns Thalasseus bengalensis, and 1 White-winged Tern.

Alfred Chia, Lim Kim Keang and Veronica Foo did a quick shorebird count at Chek Jawa on 24th. Their tally included 200 Lesser Sand Plovers Charadrius mongolus, 9 Terek Sandpipers Xenus cinerea , 7 Barred-tailed Godwits Limosa lapponica, 15 Whimbrels Numenius phaeopus, 35 Grey Plovers Pluvialis squatarola, 25 Little Terns Sternula albifrons, 3 Pacific Golden Plovers Pluvialis fulva, 2 Great-billed Herons Ardea sumatrana and 2 Common Sandpipers Actitis hypoleucos.
Mangrove Whistler caught the eyes of James Tann at Pulau Ubin.
With more birders and photographers in the field it was not surprising that a good number of rare and uncommon resident species were reported, most of them from Pulau Ubin. The elusive Mangrove Blue Flycatcher Cyornis rufigastra, was heard calling along the Chek Jawa boardwalk at Pulau Ubin on 1st by Low Choon How and heard again by Veronica Foo on 3rd. Staying at Ubin, Veronica added 3 Black-crested Bulbuls Pycnonotus flaviventris, from Butterfly Hill on the 15th, an unusual record for Ubin. A day later James Tann returned with great photos of the Mangrove Whistler Pachycephala cinerea, a much sought-after island species. There were two birds at Ketam according to Adrian Silas Tay.

The NParks survey team and volunteers did one better when they found a juvenile Barred Eagle Owl Bubo sumatranus, among the durian trees on the 18th. Subsequent visits confirmed the presence of its parents nearby although out of sight. This is the first evidence of the presence of a breeding family of this rare owl in Singapore.

The female Black Hornbill Anthracoceros malayanus, made an appearance on 21st (Alan OwYong) feeding together with the Oriental Pieds at Butterfly Hill. During the hunt for the owl, See Toh Yew Wai, Francis Yap and friends spotted a Ruddy Kingfisher Halcyon coromanda, there on 23rd. This could be our resident minor race or a migrant. The previous earliest arrival date of the migratory Ruddy Kingfisher was also on the 23rd at Pasir Ris Mangroves in 1989. The last uncommon record for Ubin were 2 Cinereous Bulbuls Hemixos cinereus, a non-breeding visitor, seen by Lim Kim Keang, Alfred Chia and Veronica Foo on 24th.
Three White-rumped Munias at Sentosa Cove on 18th. Photo: Lim Kim Seng.
Other notable residents was a King Quail Excalfactoria chinensis, from Kranji Marshes on 10th by Martin Kennewell, 14 Lesser Whistling Ducks Dendrocygna javanica, at Lorong Halus pond on 15th by Lim Kim Keang, 3 White-rumped Munias Lonchura striata, at Sentosa Cove on 18th by Lim Kim Seng. A high count of 6 Red-legged Crakes were seen and heard calling at Bukit Brown on 19th and 20th by Marcel Finlay. An Eastern Barn Owl Tyto delicatula, at Buloh Crescent on 29th by Derrick Wong, 4 Lesser Adjutants Leptoptilos javanicus, seen flying from Kranji Marshes Tower on 30th by Martin Kennewell and a Yellow-crested Cockatoo Cacatua sulphurea, at Sentosa on 30th by Lim Kim Seng. The White-rumped Munia is a new record for Sentosa but it’s status will required verification. The sighting of the 4 Lesser Adjutants was the largest for this former resident so far in Singapore. Lets hope they will re-establish here again.
