Gulls come from the Laridae family. These birds are found around the world. The adult gull can be identified by its feet, bill, wing-tips, plumage and size. Immature gulls are very hard to identify; they take 2-4 years to mature. They have slightly hooked beaks and square or rounded tails. Some gulls are called seagulls because they live near the ocean, others are found nesting inland. Gulls will seldom dive. They eat a variety of food and garbage: marine animals, plants, and carrion.
