Audubon's oriole (Icterus graduacauda), formerly known as the black-headed oriole, is a New World passerine inhabiting the forests and thickets of southeastern Texas and the Mexican coast. It is the only species to have a black hood and yellow body. It is divided into four subspecies and two allopatric breeding ranges. The westernmost range extends from Nayarit south to southern Oaxaca, whereas the eastern range stretches from the lower Rio Grande valley to northern Querétaro. Like most Central American birds, it is not a migratory species and does not display significant sexual dimorphism. DNA analysis of the ND2 and cyt-b genes strongly suggests that I. graduacauda is most closely related to I. chrysater, the yellow-backed oriole. It is a member of the genus Icterus and therefore should not be confused with the Old World orioles.
The male of the species has a black hood, mandible, and throat, as well as a black tail. Wings are black, but the remiges and rectrices (flight feathers) are fringed with... Wikipedia →

Likely
About 40% of wildlife watchers report an Audubon's Oriole sighting in Cumbres de Monterrey National Park on a given day, based on 877 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 275 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
January, May–June, August and November
In those months about 50% of wildlife watchers report an Audubon's Oriole in Cumbres de Monterrey National Park on a given day, against about 30% in October, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Audubon's 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.
Only Cumbres de Monterrey National Park, in our data
Cumbres de Monterrey National Park is the only park on Wallace's Line with enough records to rate Audubon's Oriole sightings: about 40% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Audubon's Oriole is recorded against all the birds logged in Cumbres de Monterrey National Park (877 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.
