Family Recurvirostridae, Stilts & Avocets
The Recurvirostridae are a family of birds in the wader suborder Charadrii. It contains two distinct groups of birds, the avocets (one genus) and the stilts (two genera).
Avocets and stilts range in length from 30 to 46 cm (12 to 18 in) and in weight from 140 to 435 g (4.9 to 15.3 oz); males are usually slightly bigger than females. All possess long, thin legs, necks, and bills. The bills of avocets are curved upwards, and are swept from side to side when the bird is feeding in the brackish or saline wetlands they prefer. The bills of stilts, in contrast, are straight. The front toes are webbed, partially in most stilts, and fully in avocets and the banded stilt, which swim more. The majority of species' plumage has contrasting areas of black and white, with some species having patches of buff or brown on the head or chest. The sexes are similar.
Their vocalizations are usually yelps of one or two syllables.
Avocets and stilts are a cosmopolitan family, being distributed on all the world's continents except Antarctica, and occurring on several oceanic islands. Several species are wide-ranging and a few are locally distributed.
