A familiar parking lot gull, the Ring-billed Gull breeds primarily inland in North America. It can be found along the coasts, but many of these "seagulls" never see anything except fresh water all their lives.
The adult Ring-billed Gull is a medium-sized gull, measuring 45 cm from bill to tail, having a 50-cm wingspan and weighing about 0.7 kg. Its white head, neck, underside and tail contrast with its grey wings (or back when the bird is at rest). The wing-tips are black with white spots and the legs and feet are yellow-green. A black ring encircles its yellow bill near the tip hence the name ring-billed.
Many, if not most, Ring-billed Gulls return to breed at the colony where they hatched. Once they have bred, they are likely to return to the same breeding spot each year, often nesting within a few meters of the last year's nest site. Many individuals return to the same wintering sites each winter too.
