Scientific Name: Tringa ochropus
Malay Name: Kedidi-Hijau Erasia
Chinese Name: 白腰草鹬
Breeds across the Palearctic, from Scandinavia east to eastern Siberia; winters in western Europe, tropical Africa, the Indian Subcontinent, southern China, and southeast Asia.
Size: 21-24 cm
A medium-sized sandpiper with dark upperparts and contrasting clean white underparts. Most likely to be confused with Common Sandpiper and Wood Sandpiper. Best told from Common Sandpiper by longer bill, significantly longer legs, and dark (rather than white) outer breast which forms a dark "strip" across the whole breast (while Common appears to show a "bib"). From Wood Sandpiper, told by noticeably darker upperparts with less pale spotting, much darker breast, and supercilium which does not extend behind the eye (or only faintly present behind the eye, at best).
Habitat: Inland freshwater areas, such as canals and marshes; also intertidal areas on occasion.
Behaviour/Ecology: Typically associates with Wood Sandpipers in freshwater habitat, where it is normally difficult to tell apart from that species. Stance and feeding action closer to Wood than to Common Sandpiper.
Local Status: Very rare migrant
Conservation Status: Least Concern (BirdLife International 2016)
Location: Only a handful of records; one individual in "Choa Chu Kang" in Nov 1990, another at Neo Tiew Road in Jan 2002, one at Sungei Buloh in Nov 2018, and two records of perhaps the same individual at Lim Chu Kang Lane 3 in Jan 2020 and Jan-Mar 2021.
