The Bullock's Oriole primarily inhabits the Great Basin area of southwestern Canada. Once considered a single species with the Baltimore Oriole, the two forms are now considered separate (Flood et al. 2016). The Breeding Bird Survey indicates that populations have increased moderately since about 1970. Primarily a bird of the western United States, there are currently few conservation concerns. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
The effect of habitat change on this species is not well known, but the Bullock's Oriole has likely benefited from the planting of shelterbelts and woodlots in the Great Plains area (Flood et al. 2016). Although the species regularly hybridises with the Baltimore Oriole in areas of overlap, there is little evidence of introgression and the hybrid zone appears to be stable (Flood et al. 2016).
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
