Description

The Mallard is the most familiar and widespread dabbling duck in the world. Known for the male's iconic glossy green head, yellow bill, and brilliant blue wing speculum, this species is highly adaptable and found in almost any wetland habitat.

Colour & Pattern

Striking iridescent blue-green speculum bar bordered by white margins, transitioning to dark brownish-black velvet texture.

Barb Structure

Tightly interlocked pennaceous structure with strong barbs and well-developed barbicels forming a waterproof, smooth vane.

Texture & Surface

Smooth, glossy, and water-repellent due to preen oil and dense pennaceous structure.

Key Features

Brilliant metallic blue-green iridescent patch (speculum) bordered by distinct white stripes.

Habitat

Wetlands, marshes, lakes, ponds, rivers, and agricultural fields across various temperate zones.

Geographic Range

Widespread throughout the Northern Hemisphere, including North America, Europe, Asia, and introduced elsewhere.

Ecological Role

Acts as an important seed disperser for aquatic plants and serves as prey for various raptors and carnivorous mammals.

Similar Species

American Black Duck, Wood Duck, and other dabbling ducks that possess speculum patches.

Interesting Facts

Mallards are the ancestors of nearly all domestic duck breeds. Their iridescent wing feathers use structural coloration, relying on microstructures to refract light rather than pigment.

Condition Notes

Good condition, clean vane with intact barbs and vibrant structural coloration.
