Climate and Bird Migration
Coverage from Science Advances, Bar Harbor Story, and others
Scientists and volunteers are tracking how birds move through changing environments, from rufous hummingbirds traveling between Alaska and Mexico to hawks counted during seasonal watches in Maine.
Lightweight transmitters, observation databases, long-running surveys, and ecological models help reveal migration routes, stopover habitats, shifting seasonal ranges, and changes in mountain bird distributions. Together, these efforts connect climate conditions with the timing, geography, and energy demands of avian movement while also identifying gaps in knowledge about populations and habitats.
