Scientists Pinpoint How A Flamingo cheap Canada Goose Balances On One Leg

canada goose store Most anyone who has encountered a flamingo has probably been impressed by its signature ability to balance on a single long, spindly leg for remarkably long periods of time. canada goose store

canada goose coats on sale But actually, scientists have now shown that canada goose uk black friday what appears to be a canada goose uk outlet feat requires almost no muscle activity from the bird. canada goose coats on sale

canada goose black friday sale In fact, they found even a dead flamingo’s body will naturally fall into a canada goose factory sale stable canada goose clearance sale one leg balance if positioned vertically. That research was recently published in Biology Letters. canada goose black friday sale

Canada Goose Parka Until now there have been two basic schools of thought about why a canada goose coats on sale flamingo stands Canada Goose online on Canada Goose Online one leg, Lena Ting, a biomedical engineer at Emory University and Georgia Institute of Technology, tells The Two Way. Canada Goose Parka

Canada Goose Jackets Some scientists have suggested it was a way for the bird to conserve heat that would have been lost if that foot had been in the cold water. Others thought it was a way to reduce muscle fatigue, letting canada goose coats one leg rest while the other did the work. Canada Goose Jackets

canada goose clearance But for muscles to get fatigued, the posture must actually be tiring for the bird. canada goose clearance

canada goose deals Nobody had ever tested whether the flamingo’s iconic one legged posture required any actual muscle effort until uk canada goose now. She compares the machine to a Wii balance board or a high tech bathroom scale it buy canada goose jacket “can measure the small motions of the uk canada goose outlet body when you stand.” canada goose deals

Canada Goose Outlet “And that’s the opposite of canada goose uk shop what we would expect for you canada goose store or me if I was standing on one leg and then closed my eyes, typically I would see a great increase in the amount of body sway and usually that results canadian goose jacket in people having to put their foot down,” she says. Canada Goose Outlet

It suggests that while awake and active, the bird’s swaying could be canada goose clearance correcting for other movements, ultimately settling into a position while asleep that requires little to no muscle activity.

cheap Canada Goose That was put to the test in an Canada Goose Parka experiment with a flamingo cadaver, which of course has no muscle activity because it is not living. cheap Canada Goose

First, the researchers tried manipulating the cadaver’s joint in search of Canada Goose sale a locking mechanism that could explain the stability, she says. But the joint moved very loosely and did not lock.

canadian goose jacket The key moment happened when they rotated the bird into a standing position: “We held onto its ankle. and we turned it vertically, and then all of a canada goose sudden cheap canada goose uk it just collapsed right into the position that you see when they’re standing on one leg.” canadian goose jacket

buy canada goose jacket This video shows the remarkable stability Canada Goose Coats On Sale of the cadaver, even when it is pushed and pulled in different directions. (A warning to the sensitive viewer: It is a video of a dead flamingo, though the scientists say the animal was euthanized for other reasons and was not harmed for the study.) buy canada goose jacket

canada goose This suggests Canada Goose Outlet that the reason for the animal’s stability is mechanical and is actually aided by gravity. “What canada goose black friday sale we showed is that when they go to sleep their bodies can sort of flap forward due to gravity, and then the whole thing just collapses and becomes very stable,” Ting says. canada goose

The mechanics behind a flamingo’s leg are a bit counterintuitive. The flamingo actually has an upper leg bone that is positioned horizontally, hidden among its feathers. https://www.clevelandregionalmedicalcenter.com A knee connects that bone to the long, slender part that it stands on. And the knobby bit in the center of that www.clevelandregionalmedicalcenter.com vertical portion is actually the bird’s ankle.

canada goose clearance sale When the flamingo lifts its leg, its body folds forward, so the center of gravity is pushing down on the leg from the front of the body perfectly balancing it. canada goose clearance sale

In fact, says Ting, “our research also suggests that it may require less effort for the flamingos to stand on one leg than on two.” The bird was not able to maintain this kind of passive balancing on two legs; as Ting explained, when the leg unfolded the joint “sort of collapsed” from its more stable position balanced on one leg.

This study is not inconsistent with the idea that flamingos stand on one leg to reduce heat loss, especially if the bird doesn’t need to expend much energy to do so.

buy canada goose jacket cheap But Ting says it Canada Goose Jackets may be even simpler than that: They may just balance on buy canada goose jacket cheap one leg because it’s easier for them than any other way. buy canada goose jacket cheap

Canada Goose sale It’s worth noting that lots of other birds balance on one leg too, such as wood ducks and storks. Ting says this could be a “more general mechanism that many birds use.” Canada Goose sale.
