Appearance
The adult olive tanager is about 17 cm long and is an evenly coloured, robust bird. The upper parts are a dull olive green, and the underparts are a rather paler olive green. The throat is slightly yellower than the rest of the underparts, and is streaked in the male while being a uniform pale yellow in the female. The underparts of the female are paler than those of the male, and the female has a yellowish patch in front of the eyes. The beak is relatively stout and is dark-coloured in both sexes. The lemon-spectacled tanager looks similar, apart from its yellow facial markings, but does not share the same range as the olive tanager. Also similar is the ochre-breasted tanager but again the ranges do not overlap.Status
The population of this bird has not been quantified but the total number of birds is thought to be declining. However, the bird is common in some areas of its extensive range, and the International Union for Conservation of Nature considers its conservation status to be of "least concern".Habitat
The olive tanager is a gregarious bird and often forms noisy groups of a few dozen birds, sometimes including birds of other species such as the tawny-crested tanager . In Panama a typical call is a repeated "zhwek-zhwek-zhwek" but this song is replaced in Bolivia by a more melodious series of about eight notes, this being repeated several times before going on to a different phrase.The olive tanager feeds on small insects such as beetles, cockroaches and crickets, supplementing these with berries. Breeding takes place between March and May and the nest is a cup-shaped construction of plant fibres and mosses.
