About Zimmerius chrysops albigularis (Chapman, 1924)
Zimmerius chrysops albigularis is a subspecies of the golden-faced tyrannulet. This bird measures 10.5 to 11.5 cm (4.1 to 4.5 in) in length and weighs 7.7 to 10.6 g (0.27 to 0.37 oz). Males and females have identical plumage. Adult individuals have a bright yellow forehead, supercilium, and area surrounding the eye, with a dark stripe running through the eye on an otherwise yellowish white face. Their crown, back, and rump are bright olive. Their wings are dusky, with bright yellow edges on the coverts and flight feathers. Their tail is dusky. Their throat is yellowish white, while their breast, flanks, and belly are dull whitish. They have a brown or brownish gray iris, a small, rounded, blackish bill, and gray legs and feet. This subspecies is distributed across the Andes of northwestern Venezuela, the SerranÃa del Perijá along the Venezuela-Colombia border, all three ranges of the Colombian Andes excluding the southwesternmost Nariño Department, the full length of the eastern Andean slope of Ecuador, and extends into Peru as far as the Department of San MartÃn. It inhabits the interior and edges of humid montane forest, secondary woodland, and semi-deciduous forest, and also occurs in coffee plantations and gardens. In terms of elevation range, it occurs up to 2,400 m (7,900 ft) in Venezuela, up to 2,300 m (7,500 ft) in Colombia, up to 2,200 m (7,200 ft) in Ecuador, and between 1,000 and 2,450 m (3,300 and 8,000 ft) in Peru.
