Tacarcuna wood quail

The Tacarcuna wood quail (Odontophorus dialeucos) is a species of bird in the family Odontophoridae, the New World quail. It is found in Colombia and Panama.

Taxonomy and systematics
Some authors have suggested that the Tarcarcuna wood quail and gorgeted wood quail (Odontophorus strophium), Venezuelan wood quail (O. columbianus), black-fronted wood quail (O. atrifons), and black-breasted wood quail (O. lecuolaemus) are actually a single species, but this treatment has not been accepted by the major avian taxonomic systems. The species is monotypic.

Description
The Tacarcuna wood quail is 22 to 28 cm long. Males are estimated to weigh 264 g and females 258 g. Males' crown and throat are black and the supercilium, lores, and chin are white. The sides and back of the neck are cinnamon. The back and rump are olive brown with black vermiculation and the breast and belly are chestnut speckled with white. Females are similar but their underparts are more tawny brown. Juveniles are similar to the female but the white of the chin is smaller and the black of the throat broader.

Distribution and habitat
The Tacarcuna wood quail is found along the Tacarcuna Ridge in Panama's Darién Province and Colombia's Chocó Department. It inhabits the floor of the subtropical forest at elevations between 1050 and 1450 m.

Vocalization

Status
The IUCN originally assessed the Tacarcuna wood quail as Near Threatened but has rated it Vulnerable since 2000. "The very small range of this species renders it susceptible to stochastic events and human activities".
