FLAMINGO ONE FOOT FULL
Woman who was left at death's door when her surgery was cancelled because she dared to object to a trans woman nurse in her hospital room tells her FULL shocking story - vowing: 'You can't cancel me.Thus far, though, the duo has carried out the research on their own time, sans funding. "We would need to directly image the skeletal anatomy during this behavior - for example with X-rays - to really get at it, which is a direction for future research." "We still don't know what anatomical mechanisms are engaged in the one-legged stance that allows for this, but as far as we can tell, it is related to the skeletal anatomy," Chang said. He also pointed out to the Atlantic that if the position's main purpose was conserving energy, then "one would expect flamingos to employ the one-legged resting stance constantly."Ĭhang and Ting told Discover magazine more research is forthcoming. "Importantly, these authors do not examine when and where flamingos actually utilize the behavior in question, and thus this paper does not really address the issue of why flamingos rest while on one leg."Īdded Anderson, "Providing evidence of the mechanism that supports/allows for the behavior to occur does not necessarily provide insight into why it happens in the first place." "They begin to answer the question of how flamingos are able to rest on one leg," he told the BBC. Joseph's University, who studies flamingos, called the study a "significant step forward" but said questions remain. After all, it could stand without using its muscles at all, which suggests it might be conserving energy. While the how doesn't necessarily explain why flamingos sleep on one leg, it does suggest that the bird isn't merely reducing muscle fatigue. That's the pose you have to strike in order to engage the stay mechanism," Chang told the BBC.Īs the flamingo remains nearly perfectly still while sleeping, gravity does the rest, keeping the bird in place. "If you look at the bird from the front, while they're standing on one leg, the foot is directly beneath the body which means that their leg is angled inward. All the joints essentially snap into place. Meanwhile, pulling the other leg up forces the knee to bend, which the flamingo rests on. Instead, it's centered directly under the carriage of bird. When the flamingo is ready to nod off, it lifts one leg and instinctively moves its body so its single foot isn't under its hip. Its knee, meanwhile, is hidden in bird's features at the fatter part of its body. The one you can see, that bends backward, is not the knee. As with humans, flamingos have two main joints on their leg. The bird's skeleton appears to be the key.
Instead of using active muscle force to keep their balance on one leg - as a human might, which is why you'll feel tired after that yoga class - the flamingo's unique skeletal and muscular systems allow for gravity to do the trick, the scientists reported in a study published Wednesday in Biology Letters, "We weren't expecting it to be stable, but it totally was."Įven more surprising? The cadavers couldn't stand on two legs. He was able to place the dead bird on the table, where it stood as if it were merely sleeping. Chang held one of the cadavers up by its leg, which immediately snapped into place. The duo began examining them, when something astounding happened. Alabama's Birmingham Zoo had just euthanized two flamingos, which they sent to the researchers. "We really wanted to do an experiment where we just walked over and gave them a little prod," Chang told the Atlantic. It began with an unsuccessful stakeout at Zoo Atlanta.
Atlanta biologists Young-Hui Chang of Georgia Tech and Lena Ting of Emory University set out to find a definitive reason.
