- Tringa melanoleuca
Identification
Length 29–33 cm (11½-13 in), wingspan 70-74 cm, weight 110-235 g
- Dark brown streaks on head and neck
- Long, bright chrome yellow legs
- Square white rump, not extending in an inverted 'V' up the back
- Upperpart feathering strongly spangled white in breeding plumage, slightly drabber in winter plumage
Similar Species
- Easily confused with Lesser Yellowlegs, but obviously larger (29-33 cm length, vs 23-25 cm). Bill is longer, about 1.5x the size of the head from front to back, where head and bill are about equal in Lesser Yellowlegs; bill is also stronger and often slightly upturned, and with a paler base (needle-straight, and all black in Lesser). Legs are proportionately stronger, especially the "heel" (often mis-called the "knee").
- Common Greenshank is structurally very similar, about the same size and with similar paler-based, slightly upturned bill; it differs obviously in dull greenish legs, less white spotting on the upperpart feathers, and in flight by the white rump extending in a long inverted 'V' up the back.
Distribution
Breeds Alaska and Canada
Winters to southern South America
A rare vagrant to the western and eastern fringes of the Old World; much rarer (less than annual) there than Lesser Yellowlegs.
Taxonomy
Genetically, its closest relative is the Common Greenshank (which also replaces it ecologically in the Old World); this species pair is next most closely related to Spotted Redshank[2].
Subspecies
This is a monotypic species[1].
Habitat
Tidal marshes, salt pans, muddy estuaries, freshwater lakes and streams.
Behaviour
Diet
Aquatic and land insects, small crustaceans, fish and worms.
Breeding
They lay 4 eggs in a ground nest.
Vocalisation
Call: tyew_tyew_tyew, similar to Common Greenshank.
Movements
Migration through interior North America and along coasts, on both passages.
