Baltimore Oriole Range Map

Baltimore Oriole Range Map
The Baltimore Oriole breeds from Saskatchewan and Nova Scotia south through Dakotas south to eastern Texas, Louisiana and Virginia. Recently the Baltimore Oriole was combined with the western Bullock's Oriole as a single species, the Northern Oriole. When trees were planted on the Great Plains, the two forms extended their ranges and met. Despite the differences in their appearance, it was found that they interbred, and that most birds in the central plains were hybrids, so the birds were combined into a single species. Now, it seems that in some places the birds are choosing mates of their own type, and they are considered separate species again.
