The yellow-backed oriole (Icterus chrysater) is a species of bird in the family Icteridae. Yellow-backed orioles are a yellow-bodied, sexually monomorphic species. They average 21.5 cm (8.5 in) in length from beak to tail; making it a relatively medium-sized oriole species. Exposed skin and claws are bluish-black; in adults, the bill is black, with the base of the mandible becoming bluish-grey.
Adult males display strongly contrasting yellow and black plumage. The wings, tail, shoulders, throat, and face are all black; by contrast, the back and underparts are an extremely bright yellow. Adult females closely resemble males, but yellow parts appear slightly greenish. Despite differences in plumage coloration between sexes, it is likely that this species is extremely difficult to sex in the field.
Immature yellow-backed orioles resemble adult females in overall pattern, but are greener; additionally, the flight feathers, which are black in females, are dark brown. Immature yellow-backed orioles are easily distinguished from adult females by their olive eye-line.
Similar species include the South American yellow oriole (Icterus nigrogularis). Wikipedia →

GBIF citizen-science records
It is estimated from how often the Yellow-backed Oriole is recorded against all the birds logged in Chagres National Park (68 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
