Abstract
Vocalizations of Cassin''s finch [Carpodacus cassinii] were studied in northern Utah [USA] in spring and summer of 1972 and 1973. Yearling males possessed a repertory of 97 types of song figures, and older males, 86. Each male sang a characteristic theme, sharing only the introductory 3 or 4 figure types with other males. These initial figure types could serve to identify breeding populations. Males often deleted or repeated 1 or 2 figure types but the order of figure types was consistent. Themes in songs of an individual male from a perch, during copulation, and during song flights were similar. A call given when a male fed the female at the nest was pair-specific and provided for individual recognition. The vocalizations of Cassin''s finch seemed well suited to a nomadic species breeding in a high altitude montane environment.
