The olive-green tanager (Orthogonys chloricterus) is a species of bird in the family Mitrospingidae. It is endemic to Brazil. The olive-green tanager and the three other species in family Mitrospingidae were previously placed in family Thraupidae, the "true" tanagers. A 2013 publication detailed how they did not belong there and proposed the new family for them. The International Ornithological Committee (IOC) followed suit in January 2018.
The olive-green tanager is the only member of its genus and has no subspecies. The olive-green tanager is 18 to 19 cm (7.1 to 7.5 in) long. The adult is olive green above and dull yellow below; it has a tinge of olive on the sides and flanks. The olive-green tanager is found only in southeastern Brazil, from Espírito Santo state south to eastern Santa Catarina and northeastern Rio Grande do Sul. It inhabits the interior and edges of humid montane forest at elevations of 900 to 1,800 m (3,000 to 5,900 ft).... Wikipedia →
