Description
A magnificent, large waterfowl with an all-white plumage, a long S-curved neck, and an orange bill with a black knob at the base. One of the heaviest flying birds, with a wingspan reaching up to 95 inches.
Colour & Pattern
Pure white (leucistic coloration typical of the species). There is no banding, spotting, or iridescence. The color is consistent on both dorsal and ventral surfaces.
Barb Structure
The distal portion is pennaceous (flat and cohesive), while the proximal half is highly plumulaceous (downy and fluffy) for insulation. Barbs appear intact but soft.
Texture & Surface
Smooth and somewhat waxy on the pennaceous tip (water-repellent) and extremely soft and silken on the downy lower half. It has a matte to low-gloss appearance.
Key Features
Pure white color, distinct transition from downy base to rounded pennaceous tip, and a stout white rachis suitable for a large-bodied aquatic bird.
Habitat
Found in ponds, slow-moving rivers, lakes, and coastal lagoons. Prefers areas with submerged aquatic vegetation.
Geographic Range
Native to Europe and Asia. Introduced and widely established across North America (especially the Northeast and Great Lakes) and parts of Oceania/South Africa.
Ecological Role
Large herbivore; can have significant impact on aquatic vegetation. In introduced ranges, they are often considered invasive as they compete with native waterfowl.
Similar Species
Trumpeter Swan (larger, straighter neck), Tundra Swan (smaller, yellow spot on bill), or Snow Goose (much smaller, often has black tips on flight feathers).
Interesting Facts
Mute swans are known for 'busking,' a threat display where they arch their wings over their backs. Despite their name, they are not silent and can hiss, grunt, or snort.
Condition Notes
Good condition. The feather shows natural wear and some separation of the barbs (likely a naturally molted specimen). No visible fault bars.
