Ring-billed Gull (Larus delawarensis)

General Description: In breeding plumage, Ring-billed Gulls (Larus delawarensis) are small gulls with a black ring around the yellow bill. The mantle (upper wings and back) is light gray, the wing tips are black, and the legs are yellow. Close up, the eye-ring is red.

Gulls take 2-4 years to mature. The plumage during the juvenile and subadult years differs from the adult breeding plumage, and the plumage also differs between summer and winter. Thus, there can be 7 or so different plumages for each species of gull, making identification difficult.

Taxonomy: Charadriiformes, Laridae, Larinae.

Ring-billed Gull (Larus delawarensis)
