Sounds and Vocal Behavior

Vocalizations

Galapagos Rail gives a wide range of vocalizations, which generally fall into one of five categories as described by Franklin et al. (1979): cheeping, a chichichichiroo call, a chirr call, a chatter call, and a rattle call. The cheeping call is used to maintain contact between adults and fledglings. The chichichichiroo call is a territorial advertisement that may begin with several harsh chuhchuhchuh syllables followed by several rapid chichichi syllables sharing the same pitch and ends with a quick, falling slur rrrooo. This call carries over several hundred meters and is somewhat similar to the song of Black Rail (Laterallus jamaicensis). A chirr call may be heard as a short descending trill followed by one or two chah or tah syllables. The chatter call is a low, wheezing chatter sound that begins slow and may be followed by a coarse, rapid rattle call. Galapagos Rail also may give a hissing sound, presumably to intimidate predators.

There are few available audio recordings of vocalizations of Galapagos Rail; audio recordings can be heard at Macaulay Library and at xeno-canto.
