One of the most widely recognized natural phenomena are the migrations of billions of animals each year. The timing of migrations is crucial for the fitness of mobile organisms because mistimed migration can lead to a lack of resources or difficult conditions. As a result, much work has been done on better understanding the influence of photoperiod and endogenous rhythms on the timing of migration. However there has been little work focused on the importance of social cues in the fine-tuning of migratory timing. The goal of this study is to determine if birds use social cues from conspecifics to fine-tune their initiation of migratory behavior. Red crossbills (Loxia curvirostra) are gregarious, nomadic migrants that specialize on patchily-distributed conifer seeds. Previous studies have described the effects of social cues on physiology and behavior, but no work has yet explored the influence of social cues on migratory processes that are regulated by seasonal mechanisms (i.e., photoperiod). Captive, pre-migratory focal birds were housed in individual cages and one month prior to the normal migratory period we paired birds from 2 of the 3 treatment groups with a neighboring cage containing two stimulus birds. Stimulus birds were either on the same photoperiod as focal birds or had been advanced into migratory condition through photoperiod manipulations. We discuss the changes observed in body condition (i.e., fat, mass, and muscle condition) and activity levels in the three treatment groups and examine support for the hypothesis that crossbills are using social cues from conspecifics to fine-tune the timing of migratory behavior.
