American Black Duck
Anas rubripes
Drawn from a named source but not independently confirmed. Double-check before relying on it.
Identification/population facts drawn from Cornell's All About Birds, NRCS's American Black Duck species page, and the Chesapeake Bay wintering-population figures via live search synthesis across multiple independent authoritative sources, not a single direct full-page fetch. Legal bag-limit facts are separately, directly sourced to this project's own Duck Season HuntingSeason record.
Legal status: A legal migratory game bird in Virginia during the open duck season, subject to its own daily/possession sub-limit (2 per day in the current season — see the Duck Season record), which is meaningfully lower than the mallard sub-limit given this species' population decline. Confirming the current season and this species' own sub-limit before hunting is essential, not optional, for exactly this species.
A large, dark dabbling duck of Atlantic coastal marshes — an iconic East Coast species now of real conservation concern, and a common close look-alike for a hen mallard.
Field marks
- Very dark brown/blackish body overall (much darker than a hen mallard) with a paler, grayish-brown head and face.
- Violet-purple speculum, generally without mallard's bold white borders.
- Red-to-orange legs (mallard hens have orange-yellow legs — a subtle but real distinction).
- Bright white underwing linings flash conspicuously in flight, contrasting with the dark body — a strong flight-identification mark from below.
Male, female, and seasonal plumage
- Male
- Olive-yellow bill; overall slightly darker than the female.
- Female
- Duller, more mottled bill (olive with dark markings); otherwise similar dark plumage to the male.
- Habitat
- Coastal salt marshes, tidal estuaries, and brackish impoundments — the Atlantic coast from Maine to Virginia (including Hampton Roads) holds the species' largest concentrations from October through March.
- Feeding behavior
- Dabbles for aquatic vegetation, invertebrates, and mollusks in shallow tidal marsh and estuary habitat; more tied to saline/brackish water than mallards.
- Flight profile
- Fast, direct flight; the white underwing flash against the dark body is often the quickest field mark at distance or in poor light.
- Flock behavior
- Often found in smaller, wary groups than mallards; readily mixes with mallards in winter, which is exactly where hybridization and misidentification both occur.
Migration & seasonal context
A short-to-medium-distance Atlantic Flyway migrant breeding in eastern Canada and the northeastern U.S., wintering in concentration along the mid-Atlantic coast, including the Chesapeake Bay.
Conservation context
Population has declined roughly 87% in the U.S. between 1966 and 2019 (Canadian population comparatively stable over the same period); the Chesapeake Bay wintering population specifically fell from over 200,000 to fewer than 52,000 birds. Habitat loss/degradation of Atlantic coastal and eastern Canadian breeding wetlands, plus genetic swamping from range-expanding mallards, are the primary cited pressures — a real reason to identify this species carefully before taking a duck in the mallard-hen-sized/dark-duck category.
Similar species — check before you shoot
Identification alone never establishes that a bird may legally be taken. Confirm species (and sex, where a sub-limit depends on it) before shooting.
Ethical shot selection: Given the documented population decline, take extra care distinguishing this species from a hen mallard before shooting — the underwing-flash and leg-color marks are the most reliable field cues, best confirmed before the shot, not after.
