Lophodytes cucullatus
| Conservation status | Undoubtedly declined in past with loss of nesting habitat (large mature trees near water). Now population seems to be increasing, helped by artificial nest boxes, including those intended for Wood Ducks. |
|---|---|
| Family | Ducks and Geese |
| Habitat | Wooded lakes, ponds, rivers. In summer in forested country, along creeks, narrow rivers, edges of ponds. May be in more open marsh habitats if artificial nest sites are provided. In winter on woodland ponds, wooded swamps, fresh and brackish coastal estuaries. |
forages by diving and swimming underwater, propelled by feet. Apparently finds all its food by sight; eyes adapted for good underwater vision.
10-12, sometimes 7-13. White. Eggshell thicker than in most ducks. Females often lay eggs in each others' nests, also in nests of Wood Ducks and others. Incubation is by female only, 26-41 days, usually about 33 days. Young: within 24 hours after hatching, young leave nest; female calls to them from below, young climb to cavity entrance and jump to ground. Young find their own food; female tends young for several weeks. Young fledge about 70 days after hatching.

fish and other aquatic life. Feeds mainly on small fish, crayfish and other crustaceans, and aquatic insects; also some tadpoles, a few mollusks, small amounts of plant material. Young ducklings eat mostly insects at first.
Pairs may form in late fall or winter. In most courtship displays, male's crest is prominently raised and spread. Nest site is in tree cavity near water, usually 10'-50' above ground, rarely up to 80' or more. Also uses artificial nest boxes. Nest of natural wood chips and debris in bottom of cavity, with down added.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.
Birding Without Barriers is part of a national movement to ensure that mobility impairment does not hinder people from enjoying nature.
Best known for his role on the show 'Pretty Little Liars,' Harding's new book 'Oddbirds' shares his love of birding and birds with a new audience.
