text: I have never observed any Swans of this species along the Atlantic coast, or on the rivers that open upon it, beyond Cape Hatteras in North Carolina; and although they are very numerous on the waters of the Chesapeake Bay and the streams adjacent, as well as in other parts of the Middle Districts, I am yet of opinion that the great body of them spend the winter about the Columbia river, extending their autumnal migrations westward, along the shores of the Pacific Ocean, into California, and that the columns formed by these birds when about to leave their breeding grounds in high latitudes, divide into parties, of which the less numerous bands make their way from certain points as yet unknown, towards our Middle Districts, while the rest are perhaps following the valleys of the Rocky Mountains.
