AGSG Pigeon found

[Deee]

Hello!
I had a pigeon arrive at my house in Michigan with a black AGSG band on it's right leg. We fed it since we have chickens and had appropriate food available. It has been 9 days. Unfortunately, it has decided to live on top of the freezer on our porch. I didn't capture the bird, but i got all the numbers off it's black band. It has a white band on it's left foot that does not appear to be numbered. The bird seems okay, except for never leaving the porch. It even flew in the house for a minute. Is there a way to contact the bird's owner via the band numbers? We can get the bird in a cage, I am sure.
