MBT Centennial: Cassin’s Sparrow

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 Cassin’s Sparrow. Cassin's Sparrow flies north into Great Plains states, into arid grasslands, to breed. But since perches are few and far between, it darts up into the sky singing for a mate. Once the male has found a mate, and the pair have produced chicks, it's back to Mexico to winter.
