You must be from the east, we get Bullock's Orioles in the west. Your Baltimore Oriole, and our Bullock's Oriole were considered two species, then lumped together as Northern Oriole, but again now are considered two separate species. We listers obviously prefer them as separate species.

Bullock's Oriole, note the lack of the black hood and the wider white wing bar. To me they just look plenty different to be separate species despite the hybrid overlap zone.
