Temporal changes in reproductive success and optimal breeding decisions in a long-distance migratory bird

Abstract Many avian migrants have not adjusted breeding phenology to climate warming resulting in negative consequences for their offspring. We studied seasonal changes in reproductive success of the greater snow goose (Anser caerulescens atlantica), a long-distance migrant. As the climate warms and...
