Size
Approximately 9-11 inches (23-28 cm) in length and 2.5 inches wide. This is consistent with the mid-range size for an adult Tundra Swan secondary flight feather.

Description

This is a clean, white flight feather from a Tundra Swan. These birds are massive waterfowl with a wingspan reaching up to 5.5 feet. Adults are entirely white with black legs and a black bill that usually features a small yellow spot at the base. They are known for their high-pitched, bugling calls and powerful, rhythmic wingbeats during migration.

Colour & Pattern

Pure white throughout both the dorsal and ventral surfaces. There is no banding or spotting, which is typical for adult swans. The rachis is also white, transitioning to a translucent calamus.

Barb Structure

Densely interlocked pennaceous barbs providing a stiff, aerodynamic surface. The base transitions into downy, plumulaceous barbs for insulation. Barbules are strong and well-connected.

Texture & Surface

Smooth, stiff, and somewhat waxy to the touch. The surface is highly water-repellent (hydrophobic) due to preen oil and structure, with a matte to semi-glossy finish.

Key Features

Large size, pure white coloration, thick white rachis, and the specialized aquatic texture (waterproofness) typical of large waterfowl.

Habitat

Breeds in arctic and subarctic tundra near shallow pools and lakes. Winters in large coastal bays, estuaries, and agricultural fields in temperate regions.

Geographic Range

Nearctic; breeds in northern Alaska and Canada. Migrates along specific flyways to wintering grounds on the Atlantic and Pacific coasts of the United States.

Ecological Role

They are important herbivores that influence aquatic plant communities. They also serve as an indicator species for climate change in the Arctic and wetland health in wintering areas.

Similar Species

Trumpeter Swan (larger, feather usually >12 inches), Mute Swan (more prominent curvature, different ecology), and Snow Goose (smaller, often has black tips on primary feathers).

Interesting Facts

Tundra Swans can fly at altitudes of up to 27,000 feet during migration to catch favorable tailwinds, and they often stay in family groups for the first year of a cygnet's life.

Condition Notes

Excellent condition. The vane is intact with minimal fraying. There are no signs of fault bars or parasite damage, suggesting it was molted from a healthy adult.
