The Tawny-crested Tanager is found in the Pacific lowlands of northwest North America, north through Panama to Honduras, and it also ranges around the head of the Andes in Colombia. It is generally common, like other Tachyphonus tanagers in scrubby woodland and forest borders below 800 m. Usually found in small, monospecific groups, the Tawny-crested Tanager appears to only rarely join mixed-species flocks. Within its range, both sexes should be identified reasonably easily. Males are basically all black, with a relatively conspicuous tawny-colored crest, whereas females are dark olive-brown throughout, and darker than any sympatric tanager species. For males, the only momentary risk of confusion is perhaps with the slightly smaller and dumpier looking White-shouldered Tanager (Tachyphonus luctuosus), which in some areas of overlap between the two species has a paler, more golden-colored crown. However, in all races, the male White-shouldered Tanager has an obvious white patch on the wing coverts. They are currently a common species in their area and are not considered threatened according to the IUCN despite the increasing deforestation of tropical Latin American/South American forests. The scientific name, Tachyphonus delatrii derives from Greek and Latin roots. Tachyphonus is from the Greek words takhus meaning fast, and phone meaning sound or voice, thus translates as “fast speaking” (Jobling 2010). The specific epithet delatrii honors Adolphe de Lattre, French naturalist and collector in the Neotropics (Jobling 2010). In Spanish the common name for this species is Tangara de Delattre (Hilty 2011, de Juana et al. 2012).
