Indigo Bunting
The indigo bunting communicates through vocalizations and visual cues.
A sharp chip! call is used by both sexes, and is used as an alarm call if a nest or chick is threatened.
A high-pitched, buzzed zeeep is used as a contact call when the indigo bunting is in flight.
The song of the male bird is a high-pitched buzzed sweet-sweet chew-chew sweet-sweet, lasting two to four seconds, sung to mark his territory to other males and to attract females. Each male has a single complex song,which he sings while perched on elevated objects, such as posts, wires, and bush-tops.
