Bullock's oriole (Icterus bullockii) is a small New World blackbird. At one time, this species and the Baltimore oriole were considered to be a single species, the northern oriole . This bird is named after William Bullock , an English amateur naturalist .
The male oriole is slightly larger than the female, although the size dimorphism is minimal by icterid standards. [11] [12] [13] Adults always have white bars on the wings. The adult male is orange on the underparts, shoulder patch, and rump, with some birds appearing a very deep flaming orange and others appearing yellowish orange.
