Abstract

Songs of oscine songbirds serve two social functions: mate attraction and courtship, and male-male competition over mates and resources. In a field experiment, we studied if song repertoire size predicts male size and condition in Bachman’s Sparrow (Peucaea aestivalis). We collected size measurements and complete repertoire recordings of 11 male Bachman’s sparrows from an established population at Jonathan Dickinson State Park, Hobe Sound, FL, U.S.A. Results indicate that there is a negative correlation between some male size measurements and repertoire size. Our results show an intriguing and unpredicted relationship between male physical traits and repertoire size in Bachman’s Sparrow.
