General

American Black Duck: Stocky, medium-sized dabbling duck with dark brown body, paler face and foreneck, and purple speculum bordered with black. Head is finely streaked; dark eyestripe is distinct. White underwings contrast with dark brown body in flight. Legs and feet are orange. Sexes are similar, but male has yellow bill while female and juvenile have olive-green bill.

Range and Habitat

American Black Duck: Breeds from Manitoba southeast to Minnesota, east through Wisconsin, Illinois, Ohio, Pennsylvania, Maryland, West Virginia, Virginia, and in the forested portions of eastern Canada to northern Quebec and northern Labrador. Spends winters in southern parts of its breeding range and south to the Gulf Coast, Florida, and Bermuda.

Breeding and Nesting

American Black Duck: Six to twelve creamy white to green buff eggs are laid at one-day intervals and incubated by the female for an average of 28 days. The male abandons her towards the end of incubation. Usually returns to old nesting areas, building nest on the ground, typically near water, hidden in tall grass or underneath shrubs or low branches of a conifer.

Foraging and Feeding

American Black Duck: Feeds mainly on seeds, aquatic vegetation, crop plants, aquatic insects, mollusks, amphibians, and crustaceans. Forages by grazing, probing, dabbling, or upending in shallow water; occasionally dives from the surface.

Vocalization

American Black Duck: Utters a loud, resonant "quack."

Similar Species

American Black Duck: Female, immature and eclipse male mallards are much paler, without contrast between head and body and with white borders around blue speculum. Mottled Duck has broader brown feather edges on upperparts and bluer speculum.

4 and 6 letter alpha codes

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.
