The little buttonquail (Turnix velox) is a species of buttonquail, part of a small family of birds which resemble, but are unrelated to, the true quails. This species is resident in Australia, where it is one of the more common buttonquails.
The little buttonquail is a small reddish brown bird with thin white stripes on its upper parts with a blue-grey beak, pink legs and feet, and pale eyes. The female is both larger and more brightly coloured than the male. The little buttonquail is easily distinguishable from other small quail. When flying, by its distinctly reddish or pinkish toned upperbody and the contrasting tones between parts of its wings.
While superficially resembling the true quails of the genus Coturnix, the little buttonquail differ by lacking a hind toe and a crop. The females also possess a unique vocal organ created by an enlarged trachea and inflatable bulb in the esophagus. This is used to produce a booming call.
The call patterns of the Little Button quail mainly consists of two key sounds, a loud booming “oo-ah” or “coo-oo usually sounded at night. When startled, the little buttonquail has a large squeaking call, composed of a few “chip chip-chip” sounds.
