The black-backed bush tanager (Urothraupis stolzmanni), also known as the black-backed bush-finch, is a species of bird in the family Thraupidae. It is the only member in the genus Urothraupis. It is found in Colombia and Ecuador. Its natural habitat is subtropical or tropical moist montane forests.
The black-backed bush tanager was formally described in 1885 by Władysław Taczanowski and Hans von Berlepsch from specimens collected by the Polish zoologist Jan Sztolcman (sometimes written Jean Stolzmann) on the eastern slopes of the Tungurahua Volcano in central Ecuador. The ornithologists introduced the monospecific genus Urothraupis and coined the binomial name Urothraupis stolzmanni. The genus name combines the Ancient Greek oura meaning "tail" with thraupis, an unidentified small bird, used by ornithologist for tanagers. The specific epithet honors the collector Sztolcman/Stolzmann. A 2014 molecular phylogenetic study of the tanager family Thraupidae found that the black-backed bush tanager is a member of the subfamily Poospizinae and has a sister relationship to the pardusco in the monospecific genus Nephelornis. The black-backed bush tanager is monotypic: no subspecies... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black-backed Bush Tanager is recorded against all the birds logged in Los Nevados National Natural Park (253 verified sightings from 2019 to 2026), calibrated against known sighting rates.
