Tundra Swan (Whistling Swan)

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.

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.

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

The rachis is thick, sturdy, and ivory-white, exhibiting high rigidity. Barbs emerge at a consistent acute angle, maintaining a tight, wind-resistant vane density.

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.

Located on the inner wing (secondary). Its relative symmetry compared to primary feathers and its broad width indicate its role in providing lift during flight from the mid-wing section.

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

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

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

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.

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).

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.

Swan feathers have historically been used for high-quality quill pens and in ceremonial regalia by various indigenous circumpolar cultures. In Europe, they were once a symbol of royalty.

Look for these in late summer near tundra molting sites or in late fall/winter along coastal mudflats and flooded cornfields where swans congregate to forage.

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.
