General Description: Ring-billed Gulls (Larus delawarensis) are small gulls with a black ring around the yellow bill. In breeding plumage, 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. |
