title: White-Crowned Sparrows (Zonotrichia leucophrys nuttalli) to Song.
abstract: The pattern of responses of both male and female white-crowned sparrows to playback of recorded song depends on whether the female has eggs, nestlings, or fledglings, and on the behavior under consideration. These patterns can be understood in the context of the behavior patterns appropriate during each of the different stages of the reproductive cycle.
