A pelican is any of several very large water birds with a distinctive pouch under the beak belonging to the bird family Pelecanidae. Along with the darters, cormorants, gannets, boobies, frigatebirds, and tropicbirds, it makes up the order Pelecaniformes. Like other birds in that group, pelicans have all four toes webbed (they are totipalmate). Modern pelicans are found on all continents except Antarctica. They are birds of inland and coastal waters and are absent from polar regions, the deep ocean, oceanic islands, and inland South America.

[edit] Anatomy and behavior

Pelicans can grow to a wingspan of three meters and weigh 13 kilograms, males being a little larger than females and having a longer bill.

Pelicans have two primary ways of feeding:

• Group fishing: used by white pelicans all over the world. They will form a line to chase schools of small fish into shallow water, and then simply scoop them up. Large fish are caught with the bill-tip, then tossed up in the air to be caught and slid into the gullet head first.
• Plunge-diving: used almost exclusively by the American Brown Pelican, and rarely by white pelicans like the Peruvian Pelican or the Australian Pelican.

Rarely, pelicans will consume animals other than fish. In one documented case, a pelican swallowed a live pigeon,^[1][2] and anecdotal evidence has suggested that this was not an isolated incident.^[3] This is a video of the BBC reporting of the swallowed pigeon. Pelicans are gregarious and nest colonially, the male bringing the material, the female heaping it up to form a simple structure. Pairs are monogamous for a single season but the pair bond extends only to the nesting area; mates are independent away from the nest.

[edit] Symbolism

In medieval Europe, the pelican was thought to be particularly attentive to her young, to the point of providing her own blood when no other food was available. As a result, the pelican became a symbol of the Passion of Jesus and of the Eucharist. It also became a symbol in bestiaries for self-sacrifice, and was used in heraldry ("a pelican in her piety" or "a pelican vulning (wounding) herself"). Another version of this is that the pelican used to kill its young and then resurrect them with its blood, this being analogous to the sacrifice of Jesus. Thus the symbol of the Irish Blood Transfusion Service (IBTS) is a pelican, and for most of its existence the headquarters of the service was located at Pelican House in Dublin, Ireland.

For example, the emblems of both Corpus Christi College, Cambridge and Corpus Christi College, Oxford are pelicans, showing its use as a medieval Christian symbol {'Corpus Christi' - 'body of Christ'}.

This legend may have arisen because the pelican used to suffer from a disease that left a red mark on its chest^{[citation needed]}. Alternatively it may be that pelicans look as if they are doing that as they often press their bill into their chest to fully empty their pouch.

The symbol is used today on the Louisiana state flag and Louisiana state seal, as the Brown pelican is the Louisiana state bird. Likewise, the pelican is featured prominently on the seal of Louisiana State University. A pelican logo is also used by the Portuguese bank Montepio Geral.[1]

From the fossil record,^[4] it is known that pelicans have been around for over 40 million years, the earliest fossil Pelecanus being found in early Miocene deposits in France. Prehistoric genera have been named Protopelicanus and Miopelecanus. The supposed Miocene pelican Liptornis from Argentina is a nomen dubium, being based on hitherto indeterminable fragments.

A number of fossil species are also known from the extant genus Pelecanus:

• Pelecanus alieus (Late Pliocene of Idaho, USA)
• Pelecanus cadimurka
• Pelecanus cauleyi
• Pelecanus gracilis
• Pelecanus halieus
• Pelecanus intermedius
• Pelecanus odessanus
• Pelecanus schreiberi
• Pelecanus sivalensis
• Pelecanus tirarensis

[edit] Poem

The famous limerick about pelicans: "A wonderful bird is the pelican. His bill will hold more than his belican. He can take in his beak, Food enough for a week, But I'm damned if I can see how the helican." was written by Dixon Lanier Merritt in 1910. [2]
