Chevalier cul-blanc

Tringa ochropus

Chevalier brun foncé avec un ventre blanc neigeux ; en vol, il apparaît noir dessus avec une croupe blanche fortement contrastée. Il remue la queue quand il est nerveux, mais pas habituellement comme le Chevalier guignette. Il s'élève souvent abruptement lorsqu'il est dérangé et vole rapidement avec des battements d'ailes profonds, virevoltant un peu comme une hirondelle. Se reproduit dans les clairières et les marais des forêts et bois humides ; les migrateurs se trouvent dans des habitats de zones humides d'eau douce et saumâtre, en particulier sur les rives boueuses des lacs et des petits étangs. Principalement observé seul ou en petits groupes, non mélangé à d'autres espèces.

Identification

This species is a somewhat plump wader with a dark greenish-brown back and wings, greyish head and breast and otherwise white underparts. The back is spotted white to varying extents, being maximal in the breeding adult, and less in winter and young birds. The legs and short bill are both dark green.<p>It is conspicuous and characteristically patterned in flight, with the wings dark above and below and a brilliant white rump. The latter feature reliably distinguishes it from the slightly smaller but otherwise very similar solitary sandpiper (T. solitaria) of North America.<p>In flight it has a characteristic three-note whistle.

Taxonomie

The green sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the current binomial name Tringa ochropus. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ochropus is from Ancient Greek okhros, "ochre", and pous, "foot". The species is monotypic: no subspecies are recognised.

Répartition et habitat

The green sandpiper breeds across subarctic Europe and east across the Palearctic and is a migratory bird, wintering in southern Europe, the Indian Subcontinent, Southeast Asia, and tropical Africa. Food is small invertebrate items picked off the mud as this species works steadily around the edges of its chosen pond.<p>This is not a gregarious species, although sometimes small numbers congregate in suitable feeding areas. Green sandpiper is very much a bird of freshwater, and is often found in sites too restricted for other waders, which tend to like a clear all-round view.
