Tracing the Paths of Our Shared Environment

Description

Flying within and among the nations of North America, migratory birds see no boundaries. They have surged northward and southward each year, long before humans populated the Americas and borders were created. These migratory species, many of them threatened or endangered, forge a fundamental ecological link between Canada, Mexico and the United States, providing a tangible, though vulnerable, connection between the tundra, northern forests, prairies, and wetlands with the deserts and humid and dry forests of the south.
