Pelican cooling spine

There are more than half a dozen species of pelicans, but all of them have the famous throat pouch for which the birds are best known. These large birds use their elastic pouches to catch fish—though different species use it in different ways. Many pelicans fish by swimming in cooperative groups, pelican cooling spine. They may form a line or a "U" shape and drive fish into shallow water by beating their wings on pelican cooling spine surface.

The claim is accompanied by three pictures of birds with what appear to be their spines appearing to protrude out of their mouths, and an illustration of the process. Paleontologist Darren Naish added that the apparent appearance of the spine during these yawns is called glottis exposure, which involves the birds inverting the pouches beneath their beaks over their necks and chest. This helps bring the surrounding skin back into its normal position and is also related to hygiene, but is not connected to overheating. Furthermore, not all the birds are pelicans—the bird in the top left of the post is a shoebill.

Pelicans genus Pelecanus are a genus of large water birds that make up the family Pelecanidae. They are characterized by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, except for the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all pelicans become brightly coloured before the breeding season. The eight living pelican species have a patchy, seasonally-dependent yet global distribution, ranging latitudinally from the tropics to the temperate zone. Pelicans are absent from interior Amazonian South America, from polar regions and the open ocean; at least one species is known to migrate to the inland desert of Australia 's Red Centre , after heavy rains create temporary lakes. White pelicans are also observed at the American state of Utah 's Great Salt Lake , for example, some miles km from the nearest coastline the Pacific West Coast. They have also been seen hundreds of miles inland in North America, having flown northwards along the Mississippi River and other large waterways. Long thought to be related to frigatebirds , cormorants , tropicbirds , and gannets and boobies , pelicans instead are most closely related to the shoebill and hamerkop storks although these two birds are not actually true 'storks' , and are placed in the order Pelecaniformes. Ibises , spoonbills , herons , and bitterns have been classified in the same order. Fossil evidence of pelicans dates back at least 36 million years to the remains of a tibiotarsus recovered from late Eocene strata of Egypt that bears striking similarity to modern species of pelican.

The species is susceptible to bioaccumulation of toxins and the destruction of nesting trees by logging.
