Shifting avian spatial regimes in a changing climate

Nature Climate Change, Published online: 24 June 2019; doi:10.1038/s41558-019-0517-6

Highly mobile taxa, like birds, occupy ecosystems that lack fixed boundaries, and tracking how these spatial regimes respond to environmental change is difficult. Avian route data show the spatial regimes of Great Plains bird communities have shifted poleward and reorganized over the past 46 years.
