Species Description
The Baltimore Oriole, so named because its colors resembled those on the coat of arms of Lord Baltimore, is the state bird of Maryland; the recognizable bright plumage of the male is not attained until the bird’s second autumn. Though it prefers to breed in deciduous or mixed forests of eastern North America, it has adapted well to suburban and urban areas, as well. The Baltimore Oriole eats insects, berries and nectar, and has been known to frequent hummingbird feeders; it forages in trees and shrubs, occasionally making short flights to catch insects on the wing. Its preferred food, however, is caterpillars – large ones are smashed against a rock to break them open and avoid the setae (stiff, hair-like structures on the skin).
