I live in Worth, IL and have found a reddish brown and white pigeon. I can make out a partial tag of NPA 113 and there's a 7 in there. I can't get close enough to see anymore. Does anyone have any suggestions on what I should do? The pigeon is friendly enough and I have given it water and some bread. I do live in an apartment and can't have pets, so he has been outside on my window sill and balcony mostly.
