American White Pelican
(In the Natural Reserve of Castillo de las Guardas)

Description: The plumage is quite white except for the primary and secondary feathers of the alas that are black. Both genres have the same appearance. The males are bigger than the females, but the difference of size in many couples is not the sufficient thing to be able to distinguish them to simple sight. The weight average of the males is of 7 kg, rarely reaching 14 kg. The weight of the females is from 5 to 9 kg. Of length it achieves from 1.3 to 1.75 meters, with an importance in the wings from 2.4 to 2.9 meters. The beak has a length from 28 to 47 cm.

Only one of this species is a horny comb that him grows in the top part of the beak. This comb develops both to the females and to the males, remaining during the season of anidación. This one is the major difference between this species and the White Pelican of the Old World.

Nourishment: The nourishment of the American White Pelican, as other pelicans, consists principally of fish being complemented by small crustaceans. Between the fish that they eat there are included the trouts of sweet water.

As other white pelicans of the world, these pelicans go fishing in groups. They form a semicircle while they swim. Then, as if answering to a sign, they start all the water fluttering while they advance towards the coast or the least deep waters. Seemingly they frighten the fish until they corner them. As soon as the intention is achieved, every pelican plunges the head and catches his sustenance.

Anidación: The season of anidación is during the spring and boreal summer, from April to August. It nests in colonies, usually in islands in lakes of sweet water. The family nucleus is the couple, a macho with a female. Every year a new couple is formed. In captivity some couples have become permanent, raising meeting several years.

The nest is in the soil, can be a considerable accumulation of grasses and other plant materials or maybe you upset a light depression in the land. Thing of supporting the peace between neighbors, the distance between every nest is that one of the stuck-up neck more the beak or a nest for every two square meters (0.5 nests for square meter).

The usual nestful counts of two eggs. The incubation is effected(carried out) by two parents and capture of 29 to 36 days. The pigeons are born plucked and depend in its entirety on the parents. They use for yes same to 75 days.

Longevity: In the nature to this pelican there is estimated a longevity of 26.4 years. The mortality of the pigeons is high, being considered in approximately 40 %.
