Lemon-spectacled Tanager
Chlorothraupis olivacea
Chunky tanager, unlikely to be mistaken within limited range from eastern Panama to extreme northwest Ecuador. Mostly dull olive with brighter yellow throat and bold yellow spectacles. Note its stout bill. Sexes similar. Prefers the interior of humid lowland forest, up to around 400 m. Typically found in small groups or pairs in the understory to middle levels, often with mixed-species flocks. Often detected by its loud squeaky chatters.
识别特征
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.

行为
The lemon-spectacled tanager frequents the understorey of lowland wet forests and forest edges, seldom moving above 800 m (2,600 ft) and usually staying below 400 m (1,300 ft). It often occurs in groups of up to four birds, but sometimes forms part of small mixed flocks where it often appears to be the flock leader. It is a noisy species with a loud call, often a rapidly repeated "treu-treu-treu-treu". It feeds on insects and some plant matter.
