Yellow-green Brushfinch

The yellow-green brushfinch is about 17 to 18 cm (6.7 to 7.1 in) long. The sexes have the same plumage. Adults have a black crown and the rest of their head is brownish gray mottled with black. Their back is olive green and their rump and uppertail coverts are a darker olive green. Their wings and tail are black but for bright yellow at the bend of the wing. Their breast and belly are yellowish olive green, their undertail coverts olive green, and their flanks a darker olive green. They have puffy lemon yellow feathers on their tibiae. They have a burnt rusty red iris, a black bill, and brownish legs and feet.

The yellow-green brushfinch is found in western Panama's Serranía de Tabasará between Chiriquí and Coclé provinces. It may also occur further northwest in Bocas del Toro Province. It inhabits montane evergreen forest in the upper subtropical and temperate zones. There it favors the understory and brushy edges. In elevation it ranges between 1,200 and 1,800 m (3,900 and 5,900 ft).

The yellow-green brushfinch's diet and foraging behavior have not been studied. They are assumed to be similar to those of its close relative the yellow-thighed brushfinch (A. tibiae), which see here.
