INTERESTING FACTS

  • From 1983-1995, they were combined with the Baltimore Oriole into a single species, the Northern Oriole. This was due to hybridization between the two species in the Great Plains. In 1995 the American Ornithologist's Union resplit the Northern Oriole back into two species.
  • The Bullock's Oriole was named after William Bullock, an English amateur naturalist.
  • They are one of the few bird species that will puncture and eject Brown-headed Cowbirds' eggs. They sometimes damage their own eggs in the process, but the benefit of this behavior far outweighs the cost.
  • A group of orioles are collectively known as a "pitch" and a "split" of orioles.
