Abstract

Despite the Hermit Thrush's wide distribution and exceptional singing ability, its vocal behavior is poorly known. In recorded samples from Arizona and New England, we show that males have repertoires of 6 to 12 discrete song types. Those types can be presented in highly regular sequences, but the order varies among males, perhaps depending on context or motivation. Arizona and New England songs differed in several frequency and temporal features, such as the duration and frequency of the introductory whistle and the remainder of the song, suggesting regional differences in Hermit Thrush songs. How these geographic differences in song are influenced by song development and dispersal should be a focus of future research.
