6 Things You Won't Believe Animals Do Just Like Us

But now that scientists know that parrots have signature calls, a few questions come up, like: Who gets to decide the signature call that's given to each parrot chick? Is it the parrots themselves who decide what they should be called, thus making it an innate characteristic? Is some sort of alpha parrot handing out identifying sounds? In order to answer all these questions, researchers at Cornell University filmed parrots in the wild of Venezuela, along with their newborn chicks, to see exactly when and how a parrot got its name.

What the scientists found was that it was not the parrot newborns who got to choose their signature calls. Instead, it was the proud parrot parents who gave each chick its name. Much like a human, the adult parrot will choose a name for its young soon after it's born. Each parrot, though, may tweak its own signature call as it grows older, elongating a whistle here or shortening a chirp there, essentially giving itself a nickname.
