wallpapers of cute animal pink pelican poster

The Pelican breeds from southeastern Europe through Asia and in Africa in swamps and shallow lakes. Their tree nest is a crude heap of vegetation. This is a large pelican, at a mass of 10 kg, 160 cm long and with a 280 cm wingspan. Pelicans catch fish in their huge bill pouches while, like most, swimming at the surface. This species has declined greatly through habitat loss and persecution.his is a small pelican, but its wingspan is still around 2.4 m (7.9 ft) and its average weight is 5.5 kg (12 lbs). Plumage is grey and white, with a pink back. The top of the bill is yellow and the pouch is usually grayish. Breeding adults have long feather plumes on the head.
The main food of pink-backed pelicans is fish. In addition, they feed on a variety of small invertebrates and amphibians. They usually fish in groups, stretched out in a line to surround a shoal of fish. The pelicans then duck their heads under water at exactly the same time, frightening and confusing the fish which are scooped up in the birds’ pouches.The species nests colonially in trees, reeds or low bushes along waterfronts as well as (less often) on the ground on sandy islands and in mangroves. The nest is small and constructed of sticks, and may be situated at elevations of 10-50 m above the ground. A single tree may contain many nests that can be very close together (often touching), and a single pair will refurbish and re-use the same nest from year to year if it has not collapsed.
Pelicans swim well with their short, strong legs and their feet with all four toes webbed (as in all birds placed in the order Pelecaniformes). The tail is short and square, with 20 to 24 feathers. The wings are long and have the unusually large number of 30 to 35 secondary flight feathers. A layer of special fibers deep in the breast muscles can hold the wings rigidly horizontal for gliding and soaring. Thus they can exploit thermals to commute over 150 km (100 miles) to feeding areas.for more pics.....
