These beautiful swans nest in the arctic and spend their winters along the Atlantic and Pacific coasts. A noisy flock passing overhead on a cold winter day is refreshing evidence of wildness still at large in the world. Note the Tundra Swan's black bill with yellow spot in front of the eye. The larger Mute Swan (<em>Cygnus olor</em>), with its orange bill and black "basal knob," was introduced to North America by early settlers as a decorative species. The large and beautiful Trumpeter Swan (<em>Cygnus buccinator</em>) formerly wintered on the Chesapeake Bay, is now rare but increasing. This is in large part due to efforts currently underway to reintroduce the Trumpeter Swan in the East.
