wader in the largebird family Scolopacidae, the typical waders. It is an Arctic bird, breeding across northernScandinavia and northernAsia . It is a migratory species, wintering around theMediterranean , the southernBritish Isles ,France , tropicalAfrica , and tropicalAsia , usually on fresh or brackish water. It is an occasional vagrant inAustralia andNorth America .It is 29-33 cm long. It is black in breeding plumage, and very pale in winter. It has a red legs and bill, and shows a white oval on the back in flight. Juveniles are grey-brown finely speckled white above, and have pale, finely barred underparts. It nests on open boggytaiga , laying four eggs in a ground scrape. The call is a creaking whistle "teu-it" (somewhat similar to the call of aRoseate Tern ), the alarm call a "kyip-kyip-kyip". Like most waders, it feed on small invertebrates.The Spotted Redshank is replaced as a breeding bird further south by the
Common Redshank , which has a shorter bill and legs, and is brown and white above with some dark patterning below, becoming somewhat lighter-toned in winter.Taxonomically, it forms a close-knit group with the
Greater Yellowlegs and theGreenshank , which among them show all the basic leg and foot colours of theshanks , demonstrating that this character isparaphyletic (Pereira & Baker, 2005). These three species are the largest shanks apart from theWillet , which is altogether more robustly built.The Spotted Redshank is one of the species to which the "Agreement on the Conservation of African-Eurasian Migratory Waterbirds" (
AEWA ) applies.References
