Scientists may have finally figured out how flamingos can stand on one leg, not fall over
For flamingos, standing on one leg might actually be easier than standing on two. A report published Wednesday in The Royal Society's Biology Letters revealed that flamingos might literally be built to stand on one leg, which would explain how they're able to do so while they sleep without toppling over.
When the researchers' first idea for testing flamingos' balance — walking over to the birds in a zoo and giving them "a little prod" — was rejected, they turned to studying flamingo cadavers. To their surprise, they found that while a dead flamingo can't stand on two legs, it can still balance on one. When the researchers began studying live flamingos — by watching them until the birds dozed off — they found out flamingos' balance became better as they fell asleep.
That led researchers to realize that flamingos' fantastic balance might have something to do with their anatomy, specifically a built-in "stay mechanism." The Washington Post explained the phenomenon:

Though the researchers might be one step closer to figuring out how flamingos stand on one leg, the question of why they do so remains a mystery. Flamingo studier Matt Anderson, of St. Joseph's University, pointed out to The Atlantic that if standing on one leg saved flamingos so much energy, "one would expect flamingos to employ the one-legged resting stance constantly."
