I was thinking that. But theres a guy that brings them in from out of state to race. It's still here this morning. How does one catch a pigeon to set free? I am worried about the cats ganging up on it
He might be a lost racer.
Try to catch him. You might need a net if he's not very friendly. Then feed and water him, and read his bands. You will probably be able to read the bands and use that info to find his owner, who you can then contact and see if they want you to just feed and water him for a day and then release him, or if they want to come pick him up, etc.
