Saffron-crowned tanager

The saffron-crowned tanager (Tangara xanthocephala) is a species of bird in the family Thraupidae. Found in the northern Andes of Bolivia, Colombia, Ecuador, Peru, and Venezuela, it inhabits cloud forest, forest edges, and secondary forest, preferring areas with mossy trees. It is an average-sized species of tanager with a blue-green body and yellow head with a black forecrown, lores, orbital area, and chin.

It forages in pairs or small groups of 3–7 individuals that are part of mixed-species flocks. It is the most frugivorous species in the genus Tangara, although it also feeds on insects. It forms breeding pairs and is thought to be socially monogamous. The only known nest contained a clutch of two eggs. It is listed as being a species of least concern by the International Union for Conservation of Nature (IUCN) on the IUCN Red List, but may be threatened by habitat destruction.

The saffron-crowned tanager is an average-sized species of tanager, with a length of 12.5–13.5 cm (4.9–5.3 in) and a mass of 15–23.6 g (0.53–0.83 oz). Both sexes look similar. Adults have a blue-green body with blackish streaking on the back. The forecrown, lores, orbital area (region around the eyes), and chin are black, while the rest of the head is yellow, with an orange tinge to the crown. The wings and tail feathers are black, edged blue-green. The center of the belly and the undertail coverts are buff. The iris is dark brown, the bill is black, and the feet are gray. Juveniles are similar to adults but duller and more greenish. They also have yellowish-green instead of yellow on the head and buff-edged underparts.

The saffron-crowned tanager may be confused with the golden-eared and flame-faced tanagers. It can be distinguished by the former's black mid-crown and nape, and by the latter's solid black back and opalescent patch on wing coverts.

The saffron-crowned tanager's calls include a thin, high-pitched tsit and a high-pitched descending tsew. Its songs may be a series of squeaky, high-pitched notes.
