Abstract
Two types of vocalizations of White Carneaux pigeons were identified in experiments on schedule-induced aggression and were given pictorial representation in sound spectrograms. Characteristics of these vocalizations are examined in the context of previous descriptions of vocalizations of several varieties of pigeons during aggressive and sexual encounters in naturalistic settings. These earlier descriptions portrayed vocalizations with mnemonic phrases and the symbols of dictionary pronunciation. Data are presented that indicate that the analysis of social encounters between pigeons during schedule-induced aggression may be aided by employing these and other vocalizations as dependent variables.
