:< Maybe try bringing it to a wildlife center?

It's a rook, and I second the suggestion of taking it to a wildlife center.

Yes, i think i'm going to ask the locat veterinanian for help.

Oh, I just looked after, it's really called rook, we have the same name for them (varjú), did not know the difference in english.

I hate to say this, but if it's common or injured too badly all they'll do is kill it :c I really hope they don't do that to you though, this is a beautiful bird and its injury doesn't look...too terrible?

Looks like he has an injured wing, and almost all tailfeathers are missing. Probably he was attacked by a dog.

Or hit by a car. I've seen...similar injuries many times from pigeon hit and runs. People think they're small and stupid so why should they stop and make sure it's okay, it's really infuriating.
He's a beautiful baby, i hope he gets help! Until you can get him in, maybe give him some people foods to nibble on if he's trusting enough. I know the crows around here won't eat unless they see you eat some, but once you do they're all over it. Smart birds, them.

Yes, it could be a car too, but our house is near a small street, where cars doesn't move very fast.

Speed limit by our street is 25 and there's speedbumps. Like i said, you'd be surprised.
