The most common inland gull species in the southwest, the Ring-billed Gull can show up on any patch of water in cities or rural areas. It feeds on a wide range of food that includes fish, insects, worms, mice, eggs, carrion and garbage. It nests in colonies long the ocean and some isolated inland marshes, often with other gull species, cormorants and terns. The nest is on the ground and lined with grass and feathers.

The four-digit banding code is RBGU.
