 Flamingos are the mean girls of the animal kingdom. They pretty much act just like high school kids. Scientists have been studying flamingos and it turns out they love to roll with a click and only gravitate towards birds with similar personalities. There's the introverts, the aggressive ones, and the plastics. They can't sleep with us! But seriously, just like humans, when there's a squabble, the clicks back each other up. And this new finding just might be the key we need to improve the welfare of animals and captivity.
