Terek Sandpiper at Seletar Dam photo Francis Yap.
The Autumn migration season has began. We started seeing the arrival of the shorebirds to Sungei Buloh and the mud flats at Mandai, song birds to Bidadari and the Central Forest. On the first day of August, the Lesser Sand Plovers, Charadrius mongolus, and Common Sandpipers, Actitis hypoleucos, were seen by Zacc HD over at the shore of the Seletar Dam, while Adrian Gopal was the first to report the arrival of the Common Redshanks Tringa totanus, and Common Greenshanks, Tringa nebularia, to SBWR. Lim Kim Seng picked up a lone Whimbrel, Numenius phaeopus, on 7th, a Marsh Sandpiper, Tringa stagnatilis, and a Terek Sandpiper, Tringa cinerea, both at SBWR on 12th. He also reported a Little Ringed Plover, Charadrius dubius, over at Neo Tiew Lane 2 on 12th while a Curlew Sandpiper, Calidris ferruginea, was seen at SBWR by Robin Tan on 28th.
It was a little slower for the passerine migrants. See Toh Yew Wai photographed a needletail flying over Jelutong Tower on 9th. General consensus was a Brown-backed Needletail, Hirundapus giganteus, We had our first Asian Paradise Flycatcher, Terpsiphone paradisi, over a Venus Drive on 15th ( Jensen Seah) followed by another the next day over at Pulau Ubin by Yap Wee Jin.
A Forest Wagtail, Dendronanthus indicus, (above) photographed by Laurence Eu at the SBG’s Healing Gardens on 16th was 3 days ahead of the previous extreme date, a returning Common Kingfisher, Alcedo atthis, to the lily pond at the Gardens by the Bay on 17th ( Koh Liang Heng), Arctic Warbler, Phylloscopus borealis, at our Central Forest on 22nd by Lim Kim Keang and an uncommon Eastern Crowned Warbler, Phylloscopus coronatus, at Bukit Timah on 25th by Francis Yap. The month ended with Yellow-rumped Flycatcher, Ficedula zanthopygia, at Tuas South (Low Choon How), and a Tiger Shrike, Lanius tigrinus, (Y.W. See Toh) both on 30th. All these records were first for the season.
We had several sightings of the Oriental Honey Buzzards, Pernis ptilorhyncus, during the first week from SBG and Central Forest to SBWR. Some appeared to be on migration flying in a South-easterly direction. Others were summering juveniles like Seng Alvin’s find at Pasir Ris Park on 25th. This was where Md. Nasir photographed a Tweedale morph Torquatus resident race Honey Buzzard. Other raptors reported this month was a returning Peregrine Falcon, Falco peregrinus, to Ubin on the 1st (Y.W. See Toh), a pair of Crested Goshawks, Accipiter trivirgatus, feeding its young at Bishan Park on 14th and a Crested Serpent Eagle, Spilornis cheela, photographed by Gill Jones on 22nd at her garden at the wooded Tanglin area.
