Over the prairie west of the Mississippi, flocks of these fine aristocratic birds swirl northward during May. They fly in long parabolas sinking and rising as the whim seizes them until the undulating cloud disappears. Formerly abundant, today they are seldom seen on the Atlantic Coast in Autumn unless an onshore gale drives them in. From a fishing schooner's deck, a hundred miles or more off the New England coast. I often have seen numbers outward bound on their remarkable flight to South America.
