Behavior
Anna's hummingbirds are not social animals; they are territorial and will dive at anything that enters their territory, no matter what size. These birds migrate between summer and winter ranges. They are active during the day and may become torpid at night to conserve energy. (Russell, 1996; True, 1993)
