Looks like a rock dove. I'm never able to work with doves when reintroducing them to the wild after taking care of them until they are able to take care of themselves. The only time I've taken in a rock dove was a long time ago, it had been poisoned, probably from those poisons ment to kill starlings. ( I've raised starlings, I love that breed of bird. There is nothing wrong with them, the people who poison them are just stupid and uneducated. ) You can never feed doves that have not been on normal food easily. They won't open their mouth for the food....
