Behavioral Correlates of the Chip Note in Anna’s Hummingbird
Anna’s Hummingbirds are charismatic birds native to western North America. They are well-studied for their jewel-like coloration, hyper-aggressive behavior, and unique courtship displays. However, the meaning and usage of their most common vocalization – the chip note – has never been thoroughly investigated. This research will correlate auditory parameters of chip notes with behavioral context in order to infer broader utility and significance of the vocalization.
