Comparing vocalisations of known bush dog populations in Guyana
Recordings from three sites suggest measurable differences in call structure between populations separated by rivers.

Bush dogs are heard far more often than they are seen.
We compared 214 recordings of bush dog vocalisations from three sites in Guyana, including two populations separated by a major river system.
The introductory whine is consistent across sites, but the following group calls differ in frequency range and repetition rate in ways that appear geographically structured.
The sample is small and the recordings were made with different equipment, so we treat this as a hypothesis rather than a finding. A standardised recording protocol is being drafted.
