Habitat is home. It's the foundation for birds' survival. To reverse the massive decline of migratory birds, ABC works across vast landscapes in North America where many of our priority species breed. Working closely with the Migratory Bird Joint Ventures (JVs) and other partners, we have improved more than 9.7 million acres of bird habitats in the places where birds need us most — from the Great Lakes to the Chihuahuan Desert.
