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.

Rare
Under 5% of wildlife watchers report a Yellow-backed Oriole sighting in Caracas on a given day, based on 63 verified sightings from GBIF citizen-science data. It is the 181st most-seen of the 295 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-backed Oriole in Caracas on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Yellow-backed Oriole sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 7
Of the 7 cities where we can rate Yellow-backed Oriole sightings, Caracas ranks 6th at under 5%. The best odds are in Bogota (Colombia, about 40%), Cali (Colombia, under 5%) and Panama City (Panama, under 5%).
GBIF citizen-science records
It is estimated from how often the Yellow-backed Oriole is recorded against all the birds logged in Caracas (63 verified sightings), 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.
