Spatiotemporal variation in avian migration phenology: citizen science reveals effects of climate change.

A growing number of studies have documented shifts in avian migratory phenology in response to climate change, and yet there is a large amount of unexplained variation in the magnitude of those responses across species and geographic regions. We use a database of citizen science bird observations to...
