Identification

Distribution

Breeds from southern British Columbia, southern Saskatchewan, Montana, and southwestern North Dakota south to western Texas and northern Mexico. Winters in Mexico south to Costa Rica. Accidental vagrant in the eastern United States and Venezuela.

Taxonomy

The Bullock's Oriole was once combined with the eastern counterpart Baltimore Oriole as a single species, the Northern Oriole, because they began to interbreed on the Great Plains, when the two forms extended their ranges and met. Despite the differences in their appearance, they interbred, producing hybrids with intermediate patterns.
Polytypic. Consists of two subspecies.

Habitat

Open deciduous woods.
