Nawras (scientific name: Larus) is a genus of birds followed Alnursah platoon. The Seagull is a waterfowl often located near beaches feeds on fish. Add to that these birds are sweeping beaches to feed on the remains and waste of the many that you find on these shores. Also known as the seagull.
It usually birds medium or large-sized, white or gray color with black markings on the head or wings.Gulls have the jaws to help them devour large prey, gulls usually coastal and rarely venturing far out to sea may live seagulls with a maximum 49 years. The female put 3 eggs and when the temperature is too high the female put some of the abdomen feathers on whites to wet, and when the eggs hatch is the parents sponsored young and after 6 to 7 weeks of age the young begin to fly, but they are not independent of the parents do not leave the
colony but after 10 weeks or more. Gull species range in size from the little gull, at 120 g (4.2 oz) and 29 cm (11.5 inches), to the great black-backed gull, at 1.75 kg (3.8 lbs) and 76 cm (30 inches). They are generally uniform in shape, with heavy bodies, long wings, moderately long necks . The tails of all but three species are rounded; the exceptions being the Sabine's gull and swallow-tailed gulls, which have forked tails, and the Ross's gull, which has a wedge-shaped tail. Gulls have moderately long legs (certainly longer than the terns) with fully webbed feet. The bill is generally heavy and slightly hooked, with the larger species having stouter bills than the smaller species. The bill colour is often yellow with a red spot for the larger white-headed species and red, dark red or black in the smaller species.

The gulls are generalist feeders, indeed they are the least specialised of all the seabirds, and their morphology allows for equal adeptness in swimming, flying and walking. They are more adept walking on land than most other seabirds, and the smaller gulls tend to be more manoeuvrable while walking. The walking gait of gulls includes a slight side to side motion, something that can be exaggerated in breeding displays. In the air they are able to hover and they are also able to take off quickly with little space.
The general pattern of plumage in adult gulls is a white body with a darker mantle; the extent to which the mantle is darker varies from pale grey to black. A few species vary in this, the ivory gull is entirely white, and some like the lava gull and Heermann's gull have partly or entirely grey bodies. The wingtips of most species are black, which improves their resistance to wear and tear, usually with a diagnostic pattern of white makings. The head of gulls may be covered by a dark hood or be entirely white. The plumage of the head varies by breeding season; in non-breeding dark-hooded gulls the hood is lost, sometimes leaving a single spot behind the eye, and in white-headed gulls non-breeding heads may have streaking Most gull species are migratory, with birds moving to warmer habitats during the winter, but the extent to which they migrate varies by species. Some species migrate long distances, like the Franklin's gull, which migrates from Canada to wintering grounds in the south of South America. Other species move much shorter distances and may simply disperse along the coasts near their breeding sites
