Lemon-spectacled Tanager

The adult lemon-spectacled tanager is about 17 cm (6.7 in) in length. It is very similar in appearance to the olive tanager but the male is a rather darker shade of dull olive-green with the underparts have less yellow on the throat. The female is also similar to the female olive tanager, the underparts being yellowish-olive, and the only clear distinction between the two species is in the yellow eye-ring, possessed by both sexes of this species; the lemon-spectacled tanager also resembles the ochre-breasted tanager, but that bird has a pale eye and the underparts are more ochraceous. The three species do not share common ranges; the lemon-spectacled tanager is native to western Colombia and northwestern Ecuador, the ochre-breasted tanager occurs at higher elevations, and the olive tanager occurs further south in the eastern foothills of the Andes in southern Colombia, Peru and Bolivia, with a disjunct population in Central America.
