Description
A massive white waterbird with a wingspan reaching up to 9 feet. Known for its enormous orange bill and throat pouch used for cooperative fishing. Unlike Brown Pelicans, they do not dive from the air.
Colour & Pattern
Pure snowy white across both the dorsal and ventral surfaces. The rachis is white to translucent, lacking any melanin-based pigmentation or iridescent structural colors.
Barb Structure
Densely pennaceous throughout most of the vane for waterproofing and flight stability, transitioning to a small plumulaceous section near the calamus.
Rachis & Barb Pattern
Sturdy, white rachis with a slight curve; barbs are tightly knit at a consistent acute angle to the shaft to maintain a wind-resistant surface.
Texture & Surface
Smooth and somewhat stiff with a matte to semi-glossy finish. The surface is naturally coated with uropygial gland oils for water repellency.
Feather Placement
Originates from the ulna (forearm) of the wing as a secondary flight feather, providing the necessary surface area for lift during soaring.
Key Features
Pure white coloration, substantial width relative to length, and a rigid, water-resistant pennaceous structure typical of large aquatic soaring birds.
Habitat
Large inland lakelands, marshes, and rivers during breeding; coastal lagoons and estuaries during the winter months.
Geographic Range
Breeds in the interior of North America (West and Midwest); migrates to coastal regions of the Southern US, Mexico, and Central America.
Ecological Role
High-level predator in aquatic ecosystems; helps manage fish populations and serves as an indicator of wetland health.
Similar Species
Great Egret feathers (slenderer), Mute Swan (larger/wider), or Snow Goose (distinct black tips on primaries, but secondaries are similar).
Interesting Facts
They are one of the heaviest flying birds in North America and grow a temporary 'horn' on their upper mandible during the breeding season.
Cultural Significance
Historically significant to Indigenous peoples of the Great Basin; feathers were occasionally used in ritual attire or as symbols of water and life.
Field Identification Tips
Look for these in late summer near large freshwater lakes or zoo enclosures. Check near the water's edge where birds preen and discard old feathers.
Condition Notes
Good; shows minor wear at the edges (fraying) and some light surface soiling consistent with a naturally molted feather found on the ground.
