The Otididæ, or Bustards, occur in all parts of the Old World and Australia where there are open tracts, being only absent from Madagascar and the Malay Archipelago.

Otis (2 sp.), ranges over most of the Palæarctic region; while Eupodotis (24 sp.), has the range of the family, but is most abundant in the Ethiopian region, which contains three-fourths of the whole number of species.

The genus Cariama (2 sp.), consists of remarkable crested birds inhabiting the mountains and open plains of Brazil and La Plata. In the British Museum Catalogue of the Birds of Prey, they are classed as aberrant Falconidæ, but their anomalous characters seem to require them to be placed in a distinct family, which seems better placed among the Waders.
