Description
The Mallard is the most familiar and abundant wild duck in the world. Drakes feature a striking glossy green head, a white neck ring, chestnut brown breast, and pale gray body, while females are a mottled, protective brown. Their flight is fast and direct with rapid wingbeats.
Colour & Pattern
Rich metallic blue-green iridescence (speculum) bordered distinctly by white margins, shifting into deep dark brown and black near the base and tips. Structural coloration creates the vibrant green-blue sheen.
Barb Structure
Tightly interlocked (pennaceous) barb and barbule structure with strong barbicels forming a waterproof, cohesive vane. Intact and in good structural condition.
Texture & Surface
Smooth, stiff, and glossy with a distinctly oily and waterproof feel, typical of waterfowl feathers adapted for aquatic environments.
Key Features
Brilliant metallic blue or green speculum feather bordered by stark white bars on both the upper and lower edges, immediately identifying it as a dabbling duck secondary.
Habitat
Found in a wide variety of wetlands, including lakes, ponds, rivers, marshes, flooded agricultural fields, and urban parks.
Geographic Range
Widespread across the Northern Hemisphere; year-round resident or migrant throughout North America, Europe, and Asia.
Ecological Role
Important seed disperser for aquatic plants and a key prey item for various raptors and mammals. They play a vital role in freshwater wetland food webs.
Similar Species
American Black Duck and various teal species, though the precise coloration and white borders on the speculum help distinguish the Mallard.
Interesting Facts
Mallards are the ancestors of almost all domestic duck breeds. Their iridescent speculum colors are structural, created by the microscopic physical arrangement of the barbules rather than pigments.
Condition Notes
Good condition, clean vane with minimal wear and no visible parasitic damage or heavy fraying.
