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

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.
