About Zentrygon frenata (Tschudi, 1843)
The white-throated quail-dove, scientifically named Zentrygon frenata (Tschudi, 1843), is 30 to 34 cm (12 to 13 in) long and weighs approximately 311 g (11 oz), placing it among the largest quail-dove species. For the adult nominate subspecies Z. f. frenata, the male has a buff forehead and lower face, and a blue-gray crown. Its mantle is deep purple, and the rest of its upperparts are reddish brown. Its throat is white, its breast is gray, and its belly and flanks are dark buff. Females are browner instead of gray; juveniles resemble females but also have dark barring on both their upperparts and underparts. Other subspecies have slight differences in the coloration of their heads. The four subspecies of white-throated quail-dove have distinct north-to-south distributions: Z. f. bourcieri is found in western Colombia, and western and eastern Ecuador; Z. f. subgrisea is found in southwestern Ecuador and northwestern Peru; Z. f. frenata is found from northern Peru to central Bolivia; Z. f. margaritae is found in southern Bolivia and far northwestern Argentina. These birds live in humid evergreen montane forest in the Andes. They are most commonly found between 900 and 3,000 m (3,000 and 9,800 ft) above sea level, but can sometimes occur as low as 700 m (2,300 ft).
