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
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: Vagrant
Conservation Status: Least Concern (BirdLife International 2016)
