The bird looks like a common Rock Dove or as we in the USA say, a pigeon as in a common barn pigeon. If the bird was banded it might also be a Homing Pigeon, but the bird isn't as sleek as most Homing Pigeons are here.
Reminds me of my youth when I was a member of the Brown County Poultry and Pigeon Club in New Ulm Minnesota. I raised Bantams for show as an open breeder, not 4H, and other members raised pigeons of various breeds. I was a member for several years and rubbed elbows with a lot of pigeon breeders. I also raised some Fantails and Blue Tail Swallow pigeons, but not for show. I had wanted to cross a Homing pigeon with a Roller pigeon just for fun. Used to catch barn pigeons and tame them to stay in the coop overnight that was open to the outdoors but located in the shed with the chickens. Took a lot of first place ribbons and had one Grand Champion at the Minnesota State Fair with my bantam breeds.
