Avian populations face novel challenges with ongoing global change. By identifying the environmental cues and neuroendocrine and genetic mechanisms that determine the seasonal onset of reproduction, we will be able to predict the likelihood that populations may persist and adapt, or not, in response to rapidly changing environments. Future studies aimed at identifying the cues and mechanisms that contribute to shifts in reproductive phenology are critical for identifying ways by which populations can rapidly advance the seasonal timing of reproduction.
