Description

The canvasback is distinguished from other ducks by its sloping profile. The male has a rusty red head, white body, and black chest and rear end. The female is drabber and marked in brown and gray.

Distribution and Habitat

The canvasback breeds in prairie potholes from Alaska to the Northwest Territories, southward to Nevada and Minnesota. It winters on ocean bays, lakes and rivers across much of coastal and southern United States.

Diet

The canvasback's species name of valisineria comes from Vallisneria americana, the scientific name for wild celery, the winter buds and rhizomes of which are the duck's preferred food during the non-breeding period. It also feeds on the seeds, leaves and roots of other plants, as well as on snails and insect larvae.
