Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical with a very narrow outer vane and a broad inner vane; the tip is tapered and slightly rounded; the overall outline is elongated and curvaceous.
- Size
- Estimated at 15-18 cm (approx. 6-7 inches) in length, which is typical for a mallard's outer primary flight feathers.
- Rarity
- Very Common; one of the most abundant and recognizable duck species globally.

Description
The Mallard is a medium-sized dabbling duck. Males (drakes) feature a glossy green head and white neck ring, while females are mottled brown. This feather is a workhorse of flight, built for powerful, direct wingbeats and rapid takeoff from water.
Colour & Pattern
Muted brownish-grey base transitioning to a darker, nearly blackish-brown soot color at the distal tip; the ventral side is lighter/silver-grey; the rachis is light cream to white.
Barb Structure
Densely pennaceous and interlocked for aerodynamic integrity; the base shows plumulaceous (downy) barbs for insulation; barbs appear intact with minor separation near the base.
Texture & Surface
Smooth and stiff with a slightly waxy, water-repellent (oily) coating characteristic of waterfowl; the surface has a matte to low-lustre finish.
Key Features
Extreme asymmetry of the vanes, stiff off-white rachis, and the specific gradient from greyish-brown to a darker tip without bold barring.
Habitat
Extremely versatile; found in wetlands, lakes, ponds, rivers, marshes, estuaries, and frequently in urban parks or agricultural fields.
Geographic Range
Widespread across the Northern Hemisphere (North America, Europe, Asia); introduced to Australia, New Zealand, and South America; northern populations are migratory.
Ecological Role
Generalist consumer; they act as seed dispersers and are a primary prey source for many predators, including raptors and mammals. Populations are currently stable.
Similar Species
American Black Duck (darker overall), Northern Pintail (slimmer, more pointed), or Gadwall (different color gradients). Distribution and size are key for Mallard ID.
Interesting Facts
Mallards are the ancestors of almost all domestic duck breeds. They are capable of flying at speeds up to 55 miles per hour and can migrate thousands of miles.
Condition Notes
Good condition; the feather shows natural wear at the tip and some separation of the lower barbs, suggesting it may be a naturally molted specimen.
