English: The Ring-billed Gull is a medium sized gull that is roughly 17-21 inches (43-54 cm) in length with a 41-46 inch (105-117 cm) wingspan. Their head, neck, and under parts are white. The bill is yellow with a black ring near the tip (hence the name of the gull). The back and wings are gray; the wingtips are black with white spots. The legs and feet are yellow. The Ring-billed Gull is a “three-year gull,” in that it takes three years to reach adult plumage.

The Ring-billed Gull breeds across the northern regions of the North American continent. It is also breeds in the Great Lakes region, the Canadian Maritimes, and northern New England. In the winter it migrates as far south as the Baja Peninsula of Mexico and all the way across to the Gulf of Mexico and Cuba. The nest is a shallow depression made on the ground that is lined with grass, reeds, and rushes. The nest will typically contain two to four eggs. Both parents will incubate the eggs and both will feed the hatchlings. The young chicks learn how to fly in about four weeks.

Ring-billed Gulls are omnivores (they will eat most anything); their diet includes fish and other marine creatures, small birds, eggs, rodents, earthworms, and in populated areas, refuse from dumps, trash cans, and restaurant parking lots. These birds forage in flight or pick up objects while swimming, walking or wading. They will steal food from other birds and gulls and frequently scavenge.
