Sounds and Vocal Behavior


The common flight call of Chestnut-collared Swift is a buzzy note, given singly or strung together in a chatter. This vocalization variously is described as "buzzy, crackling chatters, zzchi zzchi-zzchi-zzchi-zzchi, etc.", with a quality that "may recall electricity crackling in pylon wires", and with an occasionally screechy note given as well (Howell and Webb 1995); as "high-pitched buzzes, bzt-bst-bzt ...., and longer buzzy rattles bjjjj .. bjjjj ..., without [the] exuberant staccato trills and outbursts of Chaetura swifts" (Hilty 2003); and as "buzzy [notes that] sound like electric crackles or static, occasionally strung into a chatter: bzzzz'tzz'tzz'tzz zz zzzz zzzzz zzzz" (Lane, in Schulenberg et al. 2010).

Additional audio recordings of vocalizations of Chestnut-collared Swift can be heard at Macaulay Library, at xeno-canto, and at Internet Bird Collection.
