Found July 20th in the evening a "Birmingham Roller" Pigeon. Its blue tag says NBRC 13 M 0550.
Please contact us at firstname.lastname@example.org. if this is your pigeon or you have any information that would help locate its owner I have sent in a notice to the National Birmingham Roller Club with the tag information.
UPDATE: The club located the owner, who is Joy's neighbor, and bird is happily at home now.
