Abstract:Vocalizations of barn (Hirundo rustica) and cliff (H. pyrrhonota) swallows in north central Texas-south central Oklahoma are described. Eight vocalizations in barn swallows and four in cliff swallows were found. Barn swallows possess a greater vocal repertoire than cliff swallows, perhaps because barn swallows nest in smaller colonies where acoustics allow greater reliance on vocal communication. It is suggested that increasing barn swallow colony sizes and sound distortion of twitter songs may be partly responsible for hybridization within the genus Hirundo presently observed in parts of Texas.
