Length: 25 in. (64 cm )
Wintering in small groups on deep rivers, lakes, ponds and occasionally in coastal bays, this deep-diving species uses the saw-toothed edges of its bill to catch and hold on to fish. During the summer they move to forested and mountainous lakes to nest high in tree cavities or rarely in rock crevices and holes in dirt banks. The nest is lined with vegetation, moss and feathers. Females alone incubate and care for the young.

The four-digit banding code is COME.
