Avian populations face novel challenges with ongoing global change. By identifying the mechanistic underpinnings responsible for establishing 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 mechanistic sources contributing to shifts in reproductive phenology are critical for identifying ways by which populations can rapidly advance seasonal timing of reproduction.
