American White Pelican (or Great White / Brown Pelican depending on specific zoo species)

A massive flight feather drifting underwater in a pool, displaying a prominent cream-white quill and dark charcoal-black vanes. Pelicans are gigantic aquatic birds with immense wingspans exceeding 8 to 9 feet, recognizable by their huge gular pouches and graceful soaring flight.

Dark greyish-black to deep slate tone on the vane surface, paired with a distinct pale white to cream-colored hollow shaft (calamus and lower rachis)

Densely packed pennaceous barbs interlocking tightly to create a sturdy, wind-resistant air-foil surface, partially split along the vane from mechanical strain/water submersion

Stiff, coarse, and water-repellent surface; currently submerged in water causing the split vanes to separate distinctly under fluid drag

Large size, thick pale hollow calamus, strong vane asymmetry, dark grey-black coloration characteristic of pelican wing tips (primaries)

In the wild: large inland lakes, rivers, coastal bays, and estuaries; in captivity: open aquatic zoo enclosures with deep swimming basins

Breeds primarily in inland North America (Canada and northern US) and winters along the Gulf Coast, California, and Mexico

Top aquatic predator consuming schooling fish and crayfish; serves as a key bioindicator of wetland water quality and fish population health

Double-crested Cormorant flight feathers (smaller, darker shafts), Great Blue Heron feathers (greyer, thinner rachis), Black Vulture primaries (shorter, differently shaped tip)

American White Pelicans do not plunge-dive like Brown Pelicans; instead, they swim in cooperative groups to herd fish into shallow water before scooping them up.

Slightly worn and water-separated; the vane has split into two major sections along the barbs due to water movement and submersion (Grade: Fair to Good)
