The majority of these species eat small invertebrates picked out of the mud or soil. Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food. There are 41 species which have been recorded in India. Ruff Green sandpiper Common greenshank

Its name comes from its original use established by hunters, as a decoy to attract wild mallards from the sky, into traps set for them on the ground.

[11] It is also sometimes known as European pochard, Eurasian pochard, or (particularly in the UK) simply pochard. [12]
The Apodiformes / ˈ æ p ə d ɪ f ɔːr m iː z / is an order, or taxonomic grouping, of birds which traditionally contained three living families—the Apodidae (swifts), the Hemiprocnidae (treeswifts), and the Trochilidae (hummingbirds); however, in the Sibley-Ahlquist taxonomy, this order is elevated to the superorder Apodimorphae, in which hummingbirds are separated into a new order, the ...
Linnaeus was not particularly familiar with the winter plumages of either the auk or the duck, and appears to have confused the two species. [3] Other old names include rotch, rotche, [4] bullbird, [5] and sea dove, although the latter sometimes refers to a relative, the black guillemot. [6] They breed on islands in the high Arctic.
