People don't really like birds, let's be honest. And it seems like the focus of most people's dislike is the wild, feral pigeon. These birds are so disruptive, that they're even deemed the "rats of the sky" due to being extremely filthy. They also carry an array of diseases, and make a mess wherever they park their feathery behinds. But the one thing people hate the most about pigeons is, you guessed it! Their poop!
