This year, 2016, marks the centennial of the first Migratory Bird Treaty, which the United States signed with Great Britain on behalf of Canada. That treaty and the three that followed — with Japan, Russia and Mexico — form the cornerstones of our efforts to conserve migratory birds, like the Ferruginous Hawk.
Many Ferruginous Hawks migrate in Spring to the far northern latitudes to breed and brood, and return to the southwest states and Mexico to winter. For others, their idea of "north" isn't so ambitious — they might fly north only as far as Nebraska or Kansas to hatch chicks. And some of them really don't migrate.
