This slim and graceful hawk is a common sight over grasslands of the Great Plains and the west, but only in summer: every autumn, most individuals migrate to southern South America. Although Swainson's Hawk is big enough to prey on rodents, snakes, and birds (and does so, while it is raising young), at most seasons it feeds heavily on large insects instead. Flocks are often seen sitting on the ground in fields where there are many grasshoppers or caterpillars.
