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 pelican cooling spine to catch fish—though different species use it in different ways. Many pelicans fish by swimming in cooperative groups.

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.

Other examples of the claim circulated on social media here and here. Kaeli Swift, a postdoctoral researcher at the University of Washington, where she teaches about ornithology and wildlife ecology, debunked the claim in a video on her YouTube channel. The most typical way birds cool down is by doing something that's akin to panting. Sharon Stiteler , a park ranger who has written books about birds, said via direct message on Twitter: "One of those birds isn't even a pelican. The top left photo actually shows a type of stork called a shoebill , she said, "although the Internet likes to call it the Murder Stork. The way their body is shaped, their pouch under their beak stretches over their neck Once someone told me that pelicans pierce their own breast when they are starving so their chicks can feed on their blood. That is not true either. The fibrous skin under a pelican's bill is called the "gular pouch," the Chicago Zoological Society's Brookfield Zoo tweeted. But have you ever seen them invert their pouch? No one is sure why they do it but it's thought it might be the pelican stretching to prepare for a big meal," it says. Skip to main content. Fact Check.

Beating the summer heat is not a big deal for humans. We can keep our bodies cool with a physical air conditioner or switch on an internal one — human sweat. But for some of our furry and feathered friends, cooling down by expressing water through the skin and allowing it to evaporate isn't at all possible. For birds like pelicans, cooling down involves a rather disturbing contortion, a meme claims. Below the meme's text is a grid with three pictures of birds with a bulge in their large beaks, then a fourth image that seems to anatomically explain how the process works.

This pelican might look like it's flipped inside out, but the behavior is perfectly normal. Well, as it turns out, it was. Yawn, indeed. The debate began when a Twitter user posted these haunted photographs and diagrams, sparking a spirited debate about what on Earth Mother Nature was thinking:. Dr Dani Rabaiotti is a science communicator and author working with the Zoological Society of London and, as she points out, these cursed images do not show either the pelican or the shoebill shunting their spine through their mouth.

Santa Fe Trail in Barton County. The northern portion was first included as part of the unorganized territory attached to the counties lying east of it. It is thought that the first white men who saw this part of Kansas were the Spaniards under Francisco Vazquez de Coronado. On October 13 of that year, Pike reached the most northern bend of the Arkansas River , about six miles east of present-day Great Bend , where he encamped for several days. Several years later, the Robert McKnight party, with a train of pack mules, followed the trail along the Arkansas River in This early route later became the historic Santa Fe Trail. For the next 50 years, wagons hauled valuable trading supplies up and down the Santa Fe Trail — through present-day Barton County, leaving in their wake a volume of history.
