You might be willing to give our flying feathered friends a pass, but there’s plenty of evidence to suggest that birds can be real cretins. Just like some people. Sometimes worse. From aggressive behavior to unquenchable greed, one look at these funny birds will have you thinking its an apt representation of what human society would look like after the Apocalypse. And if birds are distant descendants of dinosaurs, I’d rather not think of the dastardly pranks that a T-Rex and his pals would pull if they were ever cloned!

It’s not just us who think birds are idiots. Scientists are on our side. Taki’s Magazine writes about the very worst flying egomaniacs who don’t care about anyone but themselves. Take hummingbirds as an example. The egoistically smart birds are so greedy, they claim bird feeders, and won’t let anyone else near them. Not even for a taste.

Now, are you ready for something spooky and chilling about crows? I warn you, you’ll never look at them the same again. Crows are, apparently, the living embodiments of gluttony. They eat everything. And I mean everything. From garbage to tiny, beautiful baby birbs. Crows have a special appetite for robins and bluebirds. I did warn you.

Oh, and if you thought that the majestic bald eagles are exempt from criticism, think again. They’re such jerks that even other birds think they’re jerks. Bald eagles are so inept at hunting, they usually steal other birds’ prey or eat carrion, like vultures. Yuck.

Not to mention some of the biggest meanies around — Canada geese and swans. Canada geese are legendary for their aggressive animal behavior and are known for how often they attack people. Though, according to USA Today, they only do so because people are expanding into their territory and getting too close to their eggs or newborn birbs. The same goes for swans: though they’re graceful and beautiful, they will stop at nothing to defend their kids if anyone gets near them.

If you ever see a hummingbird eyeing your ice-cream or a crow looking at you funny — drop everything and run. Hide. And lock the doors. Otherwise, you might be another victim of jerk birds.
