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. Wikipedia →
