The Bullock's Oriole is the western counterpart to the Baltimore Oriole in the east. The two were considered to be the same species until genetic studies split them apart. In areas where the two species are present, they readily interbreed and produce birds with intermediate traits.

Summary

Moderate Increase
Confidence: High
Goal
Within Goal Range
The breeding range of the Bullock's Oriole is largely in the United States, but extends into southern British Columbia and just barely into Alberta. The species overwinters in Mexico and Central America. There are approximately 260,000 individuals in Canada, representing 4% of the global population and a low degree of responsibility for Canada. The Canadian population of Bullock's Oriole has shown a moderate increase relative to 1970. Confidence in this assessment is high as the Breeding Bird Survey samples much of the Canadian range and has high precision in its trends. The national population of Bullock's Oriole is within its goal range.
