Torillo Malgache

Identificación

The Madagascar buttonquail is a stocky bird with a small head and short legs and tail. Both sexes are cryptically coloured; the male has a light brown head with black and white streaking and mottling, and a greyish-brown back and wings with fine dark barring and pale-edged feathers, the barring on the outer scapulars being bolder. The tail is greyish-brown with fine barring. The chin and throat are whitish, the breast cinnamon-buff with dark barring and the belly whitish. The bill is bluish-grey, the irises white or pale grey and the legs greyish. The female is more brightly coloured. The top of the head is blackish and the mantle brownish-grey with some dark barring and cinnamon feather-edges, interspersed with some plain grey-brown feathers, giving a chequer-board effect. There is a white moustachial stripe below which the chin and upper throat form a black bib. The breast is cinnamon-pink and the belly grey with faint barring. The juvenile resembles the male but is somewhat darker and more heavily spotted.

Taxonomía

The Madagascar buttonquail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with grouse like birds in the genus Tetrao and coined the binomial name Tetrao nigricollis. Gmelin based his description on the earlier accounts by the French naturalists Mathurin Jacques Brisson and Georges-Louis Leclerc, Comte de Buffon. The Madagascar buttonquail is now placed in the genus Turnix that was introduced in 1791 by French naturalist in Pierre Bonnaterre. The genus name is an abbreviation of the genus Coturnix. The specific epithet combines the Latin niger meaning "black" with Modern Latin collis meaning "-necked". The species is monotypic: no subspecies are recognised.

Distribución y hábitat

This buttonquail is endemic to the island of Madagascar and is present over most of the island in suitable habitat. It is found in grassland, open woodland, clearings, glades, the edges of forests, sandy and bushy locations, weedy places and cultivated areas, especially where cassava is grown. It has been introduced to Mauritius, where it is now likely extinct and is present on Réunion and the Glorioso Islands, although it is unclear whether it is native there.
