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 →

Rare
Under 5% of wildlife watchers report an Audubon's Oriole sighting in San Antonio on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 184th most-seen of the 255 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 an Audubon's Oriole in San Antonio on a given day, so our monthly data shows no clear season.
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.
2nd of 2
Of the 2 cities where we can rate Audubon's Oriole sightings, San Antonio ranks 2nd at under 5%. The best odds are in Monterrey (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Audubon's Oriole is recorded against all the birds logged in San Antonio (32 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.
