An understanding of bird behavior is needed in order to approach solving bird damage problems. Behavior of blackbirds (including starlings, grackles, and cowbirds) is discussed in detail in relationship to roosting, movement, food habits, and the seasonal changes involved in these behaviors. Responses to frightening stimuli, particularly biosonics such as alarm calls, are discussed.
