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.

With luck
About 10% of wildlife watchers report a Yellow-backed Oriole sighting in Parque Natural Metropolitano on a given day, based on 532 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 328 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Yellow-backed Oriole is recorded against all the birds logged in Parque Natural Metropolitano (532 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.
