The ring-billed gull (Larus delawarensis) is a North American gull. Adult ring-billed gulls are primarily white with gray backs, dark wingtips, and yellowish feet and legs. Their bills are yellow with a distinctive black ring near the tip.1

Gulls are opportunistic feeders, consuming a variety of food sources including insects, mollusks, crustaceans, fish, and even garbage. Their bill and leg colors, along with wing patterns, help in distinguishing between different species.
