On the intelligence of corvids #2

Crows and ravens are not only able to recognize their parents, they are also able to recognize... you !

If you regularly feed a raven or a crow, they will start to recognize you, so they will often come to see you and learn to trust you. They can even bring you small gifts, which can be homemade ! Yes, corvids are capable of catching objects and putting them together to form another object which often has no utility : they're literally artists.

However, there's a bad side : if you kill a crow or a raven... beware of the other ones. They're gonna remember you, and you're gonna be blacklisted by them (in the worst case they can even attack you right on the spot) ; so if you kill a raven and see that your front door is full of bird sh*t the day after, do not be surprised. You're blacklisted by the black birbs.
