The weight is 70 to 140 g (2+1⁄2 to 5 oz). It is greatest before migration at the end of the breeding season. The female is generally slightly heavier than the male. It is streaked brown with a white eyestripe, and, in the male, a white chin. As befits its migratory nature, it has long wings, unlike the typically short-winged gamebirds. According to Online Etymology Dictionary, "small migratory game bird of the Old World, late 14c. (early 14c. as a surname, Quayle), from Old French quaille (Modern French caille), perhaps via Medieval Latin quaccula (source also of Provençal calha, Italian quaglia, Portuguese calha, Old Spanish coalla), or directly from a Germanic source (compare Dutch kwakkel, Old High German quahtala, German Wachtel, Old English wihtel), imitative of the bird's cry. Or the English word might have come up indigenously from Proto-Germanic."

Taxonomie

The common quail was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tetrao coturnix. The specific epithet coturnix is the Latin word for the common quail. This species is now placed in the genus Coturnix that was introduced in 1764 by the French naturalist François Alexandre Pierre de Garsault. The common quail was formerly considered to be conspecific with the Japanese quail (Coturnix japonica). The ranges of the two species meet in Mongolia and near Lake Baikal without apparent interbreeding and in captivity the offspring of crosses show reduced fertility. The Japanese quail is therefore now treated as a separate species.<p>Five subspecies are recognised:

Répartition et habitat

This is a terrestrial species, feeding on seeds and insects on the ground. It is notoriously difficult to see, keeping hidden in crops, and reluctant to fly, preferring to creep away instead. Even when flushed, it keeps low and soon drops back into cover. Often the only indication of its presence is the distinctive "wet-my-lips" repetitive song of the male. The call is uttered mostly in the mornings, evenings and sometimes at night. It is a strongly migratory bird, unlike most game birds.<p>The common quail has been introduced onto the island of Mauritius on several occasions but has failed to establish itself and is now probably extinct.
