About the Ring-billed Gull

The ring-billed gull (Larus delawarensis) is a medium-sized gull native to North America, breeding in Canada and the northern Contiguous United States, and wintering mainly in the United States and northern Mexico. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird. The specific delawarensis refers to the Delaware River.

The ring-billed gull is a medium-sized gull, having an average length of 43 to 54 centimetres (16.9 to 21.3 in) and a wingspan that ranges from 105 to 117 centimetres (41.3 to 46.1 in). Adults weigh from 300 to 700 grams (10.6 to 24.7 oz).

The head, neck and underparts are white; the relatively short bill is yellow with a black ring; the back and wings are silver grey with black wingtips with white 'mirrors'; and the legs are yellow. The eyes are yellow with red rims. This gull takes three years to reach its breeding plumage starting with the largely brown juvenile plumage, its appearance changing with each fall moult.

The average lifespan of an individual that reaches adulthood is 10.9 years. The oldest ring-billed gull on record was observed in Cleveland in 2021, still alive at the age of 28 years... Wikipedia →
