Ring-billed Gull:
The adult Ring-billed Gull Larus delawarensis 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.
In appearance the adult Ring-billed Gull is similar to the Herring Gull, but the Herring Gull is bigger and has flesh-coloured legs and feet and a red dot on the lower part of the bill rather than a black ring.
Young Ring-billed Gulls are a mottled brown, much different in colouring from the adults. With each successive moult, or shedding of old feathers, they lose more of the brown and develop more of the white, grey, and black patterning. They attain full adult plumage when they are three years old.
Some facts about this bird:
* will nest on almost any ground surface as long as there is water and food nearby
* is a capable parent, hatching more than 80 percent of the eggs laid
* is undergoing a continent-wide population explosion that has created a variety of management problems
* has a variable diet that might include smelt, earthworms, insects, mice, road kill, young birds, and contributions from children’s school lunch bags
* They're everywhere and annoying as heck (my quote ;D ;D ;D )
