Corvids are super-intelligent Awesome birds native to planet Earth. They can become great allies of mankind, or bitter rivals, but luckily for you, they take the individual into consideration and do not lump all of mankind together with the very worst of them. Although, not all corvids do this.
Darwin said that the fittest would survive, meaning the most adaptable. They are indeed adaptable, adapting to nearly every area of the world, utilizing intelligence and tools in their environment to succeed where other animals cannot.
They exhibit traits such as loyalty, but even vengeance.
They solve puzzles with up to 8 steps, more than most human beings can.
Though many animals have evolved enough intelligence to figure out how to steal your food, only Corvids can arrange an Ocean's Eleven-esque operation to get your brown sack lunch. Crows at the University of Montana spent hours haranguing local neighborhood dogs into chasing them all the way to campus, where they led them to knock lunches from the hands of surprised students.
Corvids can form mobs in an attempted murder, but flocks can join larger flocks for extended family reunions, or to really fuck more shit up.
In addition to their considerable intelligence, corvids also work as messengers, thieves and super spies.
They have a throat pouch to store important items and food, but also shinies.
A highly mutated form of Corvids is known as the Three-Eyed Raven, which is a corvid with omniscient powers that won't really matter much in the end.
Oh, and they can talk. Sometimes birds will just up and talk to you. So watch out for that.
Corvids are Awesome Animals who are most likely to become Revengerists. Unlike Evil Awesomes like sharks, that just want to kill, corvids usually have some important emotional or functional reason for their malice. It may not be a good reason upon retrospection, but humans are hardly in any capacity to judge corvids in this area. But if you come into their territory and you're a creepy predator, you better know they're not going to fuck around.
They have excellent recognition of human faces and will attack those who have abused them, or return or defend those who have treated them nicely (by giving treats). They can even remember after years of absence.
