That's why people around Sydney, Melbourne and other big cities in Australia have found wild cockatoos using English phrases. Now ask yourself: If you had a bird that repeated whatever you said, what's the first thing you'd do? You'd start teaching it some goddamned swear words, that's what. Well, they do that in Australia, too. So, sometimes the birds have been heard cursing at people.
Now imagine how crazy you'd think you were going if one day you were walking through the woods and you suddenly heard a disembodied bird voice tell you to eat a dick.
The weirdest part is, if the domesticated birds stay with a wild flock long enough, the words become part of the flock's calls. Scientists say that the way the birds learn their own chirps and calls is similar to how babies learn to speak, so these new calls (i.e., "Hey, asshole!") are just added to their repertoire. We're literally corrupting the birds' own language.
"Y'all bitches ain't shit AWWWK! Y'all bitches ain't shit!"
