HEARING IN THE BLACKFOOTED PENGUIN, Spheniscus demersus, AS REPRESENTED BY THE COCHLEAR POTENTIALS*

Abstract

A study of the hearing of the penguin Spheniscus demersus, in terms of the cochlear potentials, showed sensitivity over a range at least of 100 to 15,000 Hz, with the best sensitivity in the region of 600 to 4000 Hz. The form of the sensitivity function is consistent with the vocalizations of these animals. In general, this species of penguin shows good agreement with other birds in both the form and range of auditory sensitivity.
