There are 9 different species of orioles in the United States. A couple species, like the Altamira and Audubon orioles, are usually only found in south Texas. The Baltimore and orchard range through out most of the eastern US. In the west the common oriole is the Bullock's. In the central parts of the country where the range of the Baltimore and Bullock's overlap there is often crossbreeding between the two species. This oriole was photographed in Idaho.
