About Buteo albigula Philippi, 1899
Description: The white-throated hawk (Buteo albigula Philippi, 1899) measures 38 to 48 cm (15 to 19 in) in length, with a wingspan of 84 to 102 cm (33 to 40 in). Females can be up to 20% larger than males, but both sexes share the same plumage pattern. Adult individuals have brownish black faces and upperparts. The upper surface of their tail is dark brown, while the lower surface is grayish and marked with up to 10 narrow dark bands. Their chin, throat, and underparts are white, with brown streaking across the breast and belly, and rufous barring on the thighs. Adult white-throated hawks have brown eyes, and yellow cere, legs, and feet. Juveniles resemble adults, but differ in having heavy blackish streaking on the breast and flanks, streaked cheeks, and buff thighs patterned with brown bars. Distribution and habitat: The white-throated hawk occurs in the Andes mountain range, from northwestern Venezuela south through Colombia and Ecuador into Peru and Bolivia. It is also found in central Chile and western Argentina. This species inhabits humid montane forest, elfin forest, cloudforest, and adjacent open landscapes including puna grassland. Across the northern portion of its range, it lives at elevations between 1,700 and 3,500 m (5,600 and 11,500 ft). In Patagonia, it occurs between 1,000 and 2,000 m (3,300 and 6,600 ft), and in Chile it can be found from near sea level up to 1,200 m (3,900 ft).
