Behavior

Icterus galbula is not a gregarious species. Like most Icteridae its flight is strong and direct. These birds are active during the day and migrate between summer and winter ranges. (National Geographic Society, 1999; Tekiela, 1999)
Home Range
Territory size varies with habitat quality, food availability, population density, and time of breeding season. It is largest when the male is attempting to attract a female and smallest after eggs are laid. (Rising and Flood, 1998)
Communication and Perception

The male sings all summer. His song is rich and flute-like, with each individual having a distinct song. The female song is generally shorter and simpler. The call, from both sexes, is a whistled "hew-li." Nestlings beg loudly.
Baltimore orioles also use postures and movements to communicate, such as male courtship displays, female wing-flutter displays, and nestling wing-flutters when begging for food.
