Communication and Perception
Swifts communicate acoustically and visually. They are highly vocal; males and females have different calls consisting of chips and rattling or buzzy screams. Males perform aerial displays to attract mates and deter intruders. Sometimes males’ wings will produce sound during aerial displays that is caused by vibrating feathers.
Some swiftlets (Collocaliini) use echolocation calls. The calls are not used in capturing prey, but allow them to find their way in dark roosting sites.
