Birds traversing longest distances across Americas found to be at highest risk

Scientists with the National Audubon Society published research in Nature Ecology & Evolution that will help inform global efforts to protect migratory birds. In the study, "Multispecies migratory connectivity indicates hemispheric-scale risk to bird populations from global change," the researchers propose a new way to measure risk and identify where conservation efforts are most needed for species that travel between specific breeding and non-breeding regions across North, Central and South America and the Caribbean.
