Ring-billed Gull

The Ring-billed Gull is a medium-sized, white-and-gray gull with bright yellow legs, a pale eye, and a distinctive black ring around its bill in adults. They are highly gregarious, intelligent birds often seen following plows in fields or congregating in large flocks near water bodies.

Predominantly pale silvery-gray along the middle and lower web, transitioning to a stark black subterminal band and a clean white apical tip at the distal end. The rachis is white near the base and darkens toward the tip.

Pennaceous vane with tightly interlocked barbs and barbules along most of the length, transitioning to slightly looser barbs near the base. Intact condition with no visible afterfeather.

Strong, moderately thick central rachis that is white on the ventral side and gently curved. Barbs are tightly packed and set at a sharp angle to the rachis, creating a smooth, aerodynamic surface.

Smooth, firm, and slightly glossy texture designed to withstand air resistance during powerful flapping and soaring flight.

Outer wing primary flight feather. Determined by the elongated shape, stiff rachis, and distinct black subterminal markings with a white tip found on the outermost primaries of adult Ring-billed Gulls.

Silvery-gray upper web transitioning sharply to a black subterminal patch with a distinct white tip on the very end, typical of adult gull outer primaries.

Found widely across coastal marine environments, lakes, rivers, agricultural fields, parking lots, and urban landfills. Highly adaptable to human-altered landscapes.

Breeds across interior North America (Canada and northern US) and winters along the Atlantic and Gulf coasts, Pacific coast, and down into Mexico and Central America.

Acts as an opportunistic scavenger and predator, helping to clean up organic waste while serving as a food source for larger avian predators.

Herring Gull (Larus argentatus), which is larger with different primary tip patterns, and California Gull (Larus californicus), which shares a similar appearance but has darker mantle tones.

Ring-billed Gulls are known for their intelligence and opportunistic foraging habits, often stealing food from other birds or utilizing urban structures for loafing.

Gull feathers have historically been used occasionally in fly-tying, though they lack the specialized bright colors of gamebirds.

Look near lakeshores, beaches, and large inland parking lots where these gulls congregate. Molted primaries can often be found along sandy shores or grassy areas near roosts.

Good condition with minor wear at the extreme tip, indicating normal usage prior to molting.
