May have found baby pigeon?
If it is a baby pigeon, you should definately try to help it. BUt be careful. You sould only try to raise it if you are up for it and know how to. My friend once found an injured pigeon and tried to take care of it but it ended up dying becuase he didn’t know how to care for a pigeon. They are wild birds and need proper care. If you are able to do that with the help of family maybe, then definately help it and don’t leave it there to die. If you don’t feel like you can care for a pigeon, call an animal professional to help it (not to kill it) so it can survive.
