Communication and Perception
Chimney swift calls are described as a twitter (Palmer and Fowler, 1975). The most common twitterings are accelerating and decelerating chipping (Chantler and Driessens, 2000).
Chimney swifts also are likely to use touch and vision in communication. They perceive their environment through vision, hearing, touch, and a weakly developed sense of smell. (Chantler and Driessens, 2000; Palmer and Fowler, 1975)
