Description

This feather belongs to the iconic Mallard. The male (drake) is famous for its shimmering green head and yellow bill, while the female (hen) is mottled brown. Both sexes possess the brilliant blue speculum feathers on the wing, which are visible as a bright flash during flight.

Colour & Pattern

Features a deep iridescent blue to purple-violet patch (the speculum) on the outer vane, bordered by a distinct black band and a crisp white tip. The inner vane and base are a muted brownish-gray.

Barb Structure

Densely pennaceous throughout the distal half for flight stability, with a plumulaceous (downy) base for insulation; barbs are tightly interlocked with hooklets typical of waterfowl.

Texture & Surface

Waxy and smooth on the upper surface for waterproofing; the iridescent section has a glossy, metallic sheen that changes hue with the light angle.

Key Features

White terminal band, followed by a black subterminal band, bordering a brilliant iridescent blue panel on a dark gray-brown base.

Habitat

Highly adaptable; found in wetlands, lakes, ponds, rivers, marshes, and urban parks with open water and vegetation like cattails.

Geographic Range

Common throughout the Northern Hemisphere; year-round resident in Oregon and much of the United States, with migratory populations moving south from Canada.

Ecological Role

Dabbling foragers that consume aquatic plants and invertebrates; they serve as a primary prey source for hawks, eagles, and large mammals.

Similar Species

Northern Shoveler (smaller speculum, different bordering colors) and American Black Duck (speculum is more purple and lacks the distinct white leading edge).

Interesting Facts

Mallards are the ancestors of almost all domestic duck breeds. Their speculum helps individuals identify members of their own species during flight and displays.

Condition Notes

The feather appears to be in Good condition. There is minor fraying at the tip, likely from normal wear or the molting process.

Notes

In bend OR near a lake containing fish near cattails
