The Impact Of Climate Change On The Mistiming Of Bird-Resource Phenologies

Joseph Funk


As the climate continues to warm, phenologies of organisms across a variety of taxa are continuing to change. These changes are resulting in potential mismatches in resource acquisition. Specifically, migratory birds are experiencing population declines as a result of their food resources emerging at different times in their breeding grounds. I have shown how these food-timing mismatches are resulting in population declines in a range of migratory bird species, from passerines to shorebirds to hummingbirds. A failure to match their migration timing with resource availability in breeding grounds could result in significant population declines in migratory birds.
