Bullock’s Oriole

Icterus bullockii

The Bullock’s Oriole and the Baltimore Oriole were once thought to be the same species (Northern Oriole). In 1995 the species was spilt. The Bullock’s being a western bird and the Baltimore more commonly an eastern bird. Science has determined by genetic analysis that these two birds are not closely related. Yet where their ranges overlap, they will breed and hybridize.
