The Baltimore oriole (Icterus galbula) is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its common name from the resemblance of the male's colors to those on the coat-of-arms of 17th-century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole Icterus bullockii, led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.
The Baltimore oriole is the state bird of Maryland, and the namesake and mascot for the Baltimore Orioles baseball team. The Baltimore oriole was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Coracias galbula. He specified the type locality as America, but this was restricted to Virginia in 1931. Linnaeus based his account on the "Baltimore-Bird" that had been described and illustrated by the English naturalist Mark Catesby in his The Natural History of Carolina... Wikipedia →

Rare
Under 5% of wildlife watchers report a Baltimore Oriole sighting in Celestún Biosphere Reserve on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th most-seen of the 297 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Baltimore Oriole in Celestún Biosphere Reserve on a given day, against under 5% in May to March, the lowest months. That is one of Celestún Biosphere Reserve's driest months, with about 15 mm of rain against 160 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Baltimore 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.
51st of 64
Of the 64 parks where we can rate Baltimore Oriole sightings, Celestún Biosphere Reserve ranks 51st at under 5%. The best odds are in Point Pelee National Park (Canada, about 70%), Poás Volcano National Park (Costa Rica, about 60%) and Biotopo Cerro Cahuí (Guatemala, about 40%). All parks ranked.
Same genus: Icterus
The closest relatives of the Baltimore Oriole that you can see in Celestún Biosphere Reserve (genus Icterus, New World Orioles) are Hooded Oriole (about 40%), Altamira Oriole (about 20%) and Orchard Oriole (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Baltimore Oriole is recorded against all the birds logged in Celestún Biosphere Reserve (41 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.
