Ring-billed Gull

This feather belongs to the Ring-billed Gull, a medium-sized gull reaching a wingspan of about 50 inches. Adults are identified by their clean white plumage, gray mantle, and distinctive black ring around a yellow bill. They are agile fliers known for their loud, raucous calls.

Uniform pale pearl-gray (mantle color) on the dorsal surface, fading to a near-white on the ventral side. The rachis is off-white to cream. No terminal banding is present, which is characteristic of inner secondaries.

Mostly pennaceous and tightly interlocked for flight efficiency. The base features a small amount of plumulaceous (downy) barbs for insulation. Barbules are intact with visible hooklets.

Smooth, stiff, and somewhat oily to the touch. It has a matte to semi-glossy finish, which provides water resistance common in aquatic birds.

Pale pearl-gray coloration, size relative to wing proportions, and the specific curvature typical of Laridae secondaries.

Highly versatile: found in coastal areas, lakes, rivers, reservoirs, and frequently in man-made environments like parking lots and parks (like Rene levesque parc).

Common across North America; breeds in Canada and the northern US, migrating to the southern US, Mexico, and the Caribbean for winter.

Opportunistic omnivore and scavenger. They play a key role in cleaning up shorelines and managing insect populations, but can also compete with other seabirds.

Herring Gull (larger feather, darker gray), Mew Gull (slightly smaller, darker gray), and California Gull (darker gray, different geographic focus).

Ring-billed Gulls are highly opportunistic and have successfully adapted to human environments, often returning to the exact same breeding colony and even the same nest site year after year.

Good condition; the vane shows minor separation at the edges (ruffling), likely from natural wear or the molting process. No obvious parasite damage.
