The one I picked up was also brown and white.

Few years ago in Queens I was driving and this brown pigeon was in the middle of the road looking lost. It was not moving out of the way as cars came really close to hitting it. It didn’t make sense so I put some gloves on and picked it up and brought it to some grass. Started calling all types of places and no one was able to really help. Ended up putting it in a box, took it home for the night, then brought it to the Wild Bird Fund the next day. They were really helpful and seemed to care. They said it was ‘fancy pigeon’ that someone must have abandoned. Also they said something about its wings being clipped. Anyways I would get them involved if you can.
