Green-striped Brushfinch

The green-striped brushfinch is about 17 to 19 cm (6.7 to 7.5 in) long and weighs 31 to 39 g (1.1 to 1.4 oz). The sexes have the same plumage. Adults have a black crown with a wide yellowish olive-green stripe in the middle. They have a white spot above the lores and a wide olive-yellow supercilium on an otherwise black face. Their upperparts, wings, and tail are olive-green with yellow at the bend of the wing. Their throat and upper breast are white, their flanks olive-green, and the rest of their underparts grayish. They have a light brown to red-brown iris, a black bill, and pinkish gray to dark brown legs and feet. Juveniles have a blackish brown head and paler stripes on it than adults. Their upperparts are brownish olive. Their throat and underparts are olive-brown with white mottling on the throat and buffy yellow streaks on the belly.

The green-striped brushfinch has a disjunct distribution in western Mexico. One population is in southern Sinaloa, northern Nayarit, and southern Durango. The other is found from Jalisco and Colima to Morelos and western Puebla. It inhabits semi-humid to humid montane evergreen forest, pine-oak forest, and fir forest in the subtropical and temperate zones. Sources differ on its elevation range. One states it is 1,500 to 3,000 m (4,900 to 9,800 ft). A more recent one states it is 1,750 to 3,500 m (5,700 to 11,500 ft) and a very recent one almost agrees, stating it is 1,800 to 3,500 m (5,900 to 11,500 ft).

The green-striped brushfinch's diet has not been studied but is assumed to be insects and seeds. It forages on or near the ground in dense vegetation and usually singly or in pairs.
