Foo Sai Khoon was at the Sungei Buloh Wetland Reserve on 20th November 2008 and sent in this:
“I happened to be at Hide 1c (to look for the Nordmann’s Greenshank) in Sungei Buloh Wetland Reserve (SBWR) when staff of SBWR was doing bird count yesterday evening (about 5pm). One of them spotted this gem among the waders. It the same bird that Mendis mentioned. I find it strange that under different lighting situations, the colour of the feathers looked different. The 3 heavily cropped images enclosed are of the same bird.”
The Grey-tailed Tattler (Heteroscelus brevipes) is an uncommon winter visitor and passage migrant to Singapore. The first record was on 11th September 1923 after which it was not recorded again until 8th November 1967 at Changi. This uncommon visitor is not seen annually.
The main migration route from the north passes further east of Singapore, through the Philippines.
The earliest and latest sightings are 31st August and 21st April respectively.
