The unknown doves are Diamond doves from Australia - very commonly kept and easy to breed species. Smallest of the dove-family.
you know what I've always thought would be cool: to see a photo with a diamond dove standing next to a crowned pigeon, smallest and largest together. I just had a look on Google and couldn't see any. You'd think someone would have done it at some point, they are both quite common species in captivity. Sigh.
