Mallard, Wild Duck

The Mallard is a large, heavy-bodied dabbling duck. Drakes are famous for their iridescent green heads, yellow bills, and white neck rings, while hens are mottled brown. These feathers represent the subtle 'non-green' parts of the male, specifically the grey flank and various downy underparts used for buoyancy and heat retention.

The primary specimen shows a light-grey base with fine, dark-grey vermiculation or 'peppered' patterning. The smaller dark feather is likely a neck or back contour, and the white feather is a downy breast semi-plume.

Combined pennaceous and plumulaceous. The top half is tightly interlocked (pennaceous) for water shedding, while the lower half is soft and downy (plumulaceous) for insulation.

Smooth and waxy on the upper pennaceous portion (oily for waterproofing); extremely soft and airy at the base. Overall matte appearance.

Fine grey vermiculation on the pennaceous portion, broad rounded shape, and a significant downy plumulaceous base are diagnostic for Anatidae contour feathers.

Ubiquitous in wetlands, including ponds, lakes, rivers, marshes, and urban parks. Transition easily between freshwater and saltwater estuaries.

Widespread throughout the Northern Hemisphere (North America, Europe, Asia), and introduced to Australia, New Zealand, and South Africa. Mostly migratory in the north.

Generalist foragers that serve as a primary link in the wetland food web; they disperse aquatic plant seeds via their digestive tracts and provide a prey base for larger raptors.

Northern Pintail (Anas acuta) - feathers are more elongated; Gadwall (Mareca strepera) - vermiculation is usually coarser and includes more crescent shapes.

Mallards are the ancestors of almost all domestic duck breeds. They can fly at speeds up to 55 mph and are known to hybridize with many other duck species, creating unique plumage variations.

Good condition. The vanes are mostly intact with minor 'splits' near the edges. The downy bases are slightly compressed from being stored in a plastic sleeve.
