Baltimore Oriole Icterus galbula
Order: PASSERIFORMES Family: Blackbirds and Orioles (Icteridae)
The Baltimore Oriole (7-8.25”) is bright orange bird with black hood and back. Wings are black with orange shoulder patches and strongly white-edged feathers that appear as bars. Female has an olive brown back, yellow/orange underparts and white-edged feathers on the wings. Juvenile is paler overall and has gray belly and the first year male has black throat patch.
The name “oriole” is from the Latin aureolus, which means golden. The Baltimore Oriole was named in the early 1600s for George Calvert, Baron of Baltimore, whose livery stable was painted bright yellow and black. The Baltimore Oriole’s range overlaps with that of the similar Bullock's Oriole in the Midwest, and the two species are sometimes considered to be conspecific (belonging to the same species) under the name Northern Oriole because they form fertile hybrids.
