"America’s birds are in trouble. Since 1970, nearly 3 billion birds have vanished from the skies over North America.
Most of those losses have been in migratory species, which may breed in the United States or Canada in the summer before heading elsewhere for the winter. Many spend more time living on Caribbean beaches or in Costa Rican forests than they do in American backyards. “They’re really visitors to North America,” said Viviana Ruiz-Gutierrez, co-director of the Center for Avian Population Studies at the Cornell Lab of Ornithology.
Protecting these birds will require working across international borders and safeguarding all of their habitats, many of which are under threat. If migrating birds lose their winter refuges, the consequences will ripple across the hemisphere."
