Common Grackle with Half a Top Bill/Beak

So yeah, just saw this Grackle missing half of his top bill. It looked kind of twisted at the end. I felt sorry and sad for him, but I'm glad he was still able to eat sunflower seeds, etc. I hope he grows some or all of his bill back, which after reading online, I'm not sure if it's possible or not. I was just casually thinking if I could capture him I would take him to a wildlife rehabilitator, but that's pretty much impossible unless he was not able to fly, etc., and he may have a mate, family and friends around. As long as he's still able to eat, he can probably adapt to the situation (worst case scenario) and he may eventually grow some or all of it back, or at least I can hold out hope.
