Diet
 Although the American herring gull is named for the herring, it eats more than just fish! It is an omnivore and there isn't much it won't eat including shellfish, small mammals, insects, birds, eggs, carrion, and garbage.
It dives into the water for food or takes it from the surface of the water. It also captures prey on land. It sometimes drops shellfish, clams, and mussels on rocks to break them open. It also steals food from other birds.
Life Cycle
 The American herring gull nests in colonies in a variety of habitats including islands, cliffs, and beaches. The nest site is always near water. It sometimes even builds its nest on the window ledges or roofs of buildings! The nest is made in a scrape in the sand or dirt and is lined with grass, moss, pieces of plastic and other trash, and feathers. The female lays 1-3 eggs. The eggs are incubated for 26-28 days by both parents.
The chicks fledge when they are 42-45 days old.
Behavior
 The American herring gull is one species of bird that has adapted very well to human activity. It scavenges for food around dumpsters, garbage dumps, restaurant parking lots, and fishing harbors.
