Ring-billed Gull

A medium-sized gull with clean grey mantle, white head and underparts, yellow legs, and a sharp yellow bill marked with a distinct black ring. Known for its buoyancy in flight and adaptability.

Predominantly crisp white base coloration with a striking black subterminal band and a distinct white mirror or tip spot, typical of adult Ring-billed Gull outer primaries.

Tightly interlocked pennaceous structure with well-developed barbicels forming a strong, cohesive vane, showing intact barbs with minimal fraying at the very tip.

Smooth, firm, and slightly glossy texture with high rigidity to withstand strong wind resistance during flight.

Pure white tip, bold black subterminal band, and clean white web base on an outer primary feather, diagnostic for adult medium-sized gulls.

Found widely across lakes, rivers, coastlines, agricultural fields, parking lots, and urban areas, particularly near bodies of fresh or saltwater.

Breeds across interior North America, wintering along the coasts of North America, Central America, and the Caribbean. Highly adaptable and migratory.

Acts as an opportunistic scavenger and predator, helping to clean up organic waste and regulating invertebrate populations.

Herring Gull and California Gull, which are larger with more extensive dark markings or different tip patterns on their primary feathers.

Ring-billed Gulls are highly intelligent and opportunistic foragers, known to follow plows in agricultural fields to catch exposed insects and worms.

Good condition with minor wear at the extreme white tip, indicating normal usage before being molted.
