The development of vocalizations in Pipistrellus pipistrellus (Chiroptera: Vespertilionidae) during post‐natal growth and the maintenance of individual vocal signatures
The development of vocalizations during post‐natal growth in the microchiropteran bat Pipistrellus pipistrellus is described. Vocalizations served as precursors of echolocation sounds and as isolation calls used to attract mothers. Although calls judged to be echolocation precursors tended to be of...
