This is a magnificent bird, about five and one-half feet in length. Its plumage is exactly like that of the preceding except that the bill is entirely black, and the nostral is located nearer the eye. Their nesting habits and eggs are the same as those of the Whistling Swan. While a few pairs may breed within the United States by far the greater number are found in the extreme north, from Hudson Bay to Alaska. The eggs may average a trifle larger than those of the preceding species.
