Vocal similarity in long-distance and short-distance vocalizations in raven pairs (Corvus corax) in captivity

Abstract

Vocal similarity in short-distance and long-distance calls of captive raven pairs were investigated. Vocal similarity in pair partners was only found in long-distance calls, while short-distance calls were similar across all subjects.Short-distance calls may be more determined by genetic factors than long-distance calls, which might be more susceptible to learning.

Different functions of short- and long-distance calls may account for this difference.
