Ruff

Scientific Name: Calidris pugnax
Malay Name: Kedidi Ropol
Chinese Name: 流苏鹬

Range:
Found from northern Europe to Siberia, wintering in south western Europe, Africa, Middle East, Pakistan, India, Bangladesh, Sri Lanka, southern China, Japan, Southeast Asia and Australia

Taxonomy:
Monotypic

Size: M:29-32 cm, F:22-26 cm

Identification: Adult in non-breeding plumage (the form we get to see in the region) can be separated from similar size waders (Common Redshank, Common Greenshank and Great Knot) by a combination of upright stance, longish neck, relatively small head, shortish and straight bill which is slightly down-curved at tip and longish, usually orange to yellowish-green legs. Male is significantly bigger than female. Their feathers seem to “ruffle” more easily in the wind than other waders.

Habitat: Marshes, grassy areas, coastal pools and mudflats.

Behaviour/Ecology: Feeds mostly by surface pecking but often wades in fairly deep water.

Local Status: Very rare migrant

Conservation Status: Least Concern (IUCN 3.1)

Location: Two most recent sightings were that of a male mixing with a flock of Common Greenshank at Sungei Buloh on 2 Dec 2016 and 7 birds at Tanah Merah on 14 Nov 2001.
