The New World quails or Odontophoridae are small birds only distantly related to the Old World quail, but named for their similar appearance and habits. The American species are in their own family Odontophoridae, whereas Old World quail are in the pheasant family Phasianidae. The family ranges from Canada through to southern Brazil, and two species, the California quail and the bobwhite quail, have been successfully introduced to New Zealand. The stone partridge and Nahan's partridge, both found in Africa, seem to belong to the family. Species are found across a variety of habitats from tropical rainforest to deserts, although few species are capable of surviving at very low temperatures. Thirty-four species are placed in ten genera.
New World quail are generally short-winged, -necked and -tailed (although the genus Dendrortyx is long-tailed). The bills are short, slightly curved and serrated. The legs are short and powerful, and lack the spurs of many Old World galliformes. Although they are capable of short bursts of strong flight New World quails prefer to walk, and will run from danger (or hide), taking off explosively only as a last resort. Plumage varies from dull to spectacular, and many species have ornamental crests or plumes on the head. There is moderate sexual dichromism in plumage, with males having brighter plumage.
The New World quails are shy diurnal birds and generally live on the ground; even the tree quails which roost in high trees generally feed mainly on the ground. They are generalists with regards to their diet, taking insects, seeds, vegetation and tubers. Desert species in particular consume a lot of seeds.
