Diet
 The ring-billed gull eats insects, seeds, grain, fish and garbage. It is often called the "fast food gull" because it often hangs around fast food restaurants scavenging for food.
Life Cycle
 The female ring-billed gull lays two to four eggs in a hollow in the ground. The nest is made with reeds and rushes. Both the male and the female incubate the eggs. The eggs hatch in about three and a half weeks. Both parents will feed the chicks regurgitated food. The chicks leave the nest a few days after they are born. They fledge in about a month.
Behavior
 The ring-billed gull returns to its nesting site well before it is time to nest to establish its territory. It usually nests in colonies on islands in lakes with other gulls and terns. A nesting site may have as many as 1,000 pairs of ring-billed gulls.
