I was wondering if there would be any problems with keeping a ringneck dove and diamond dove together. My diamond dove is an only bird, but he gets a lot of attention!! He has an entire room to himself, away from my dogs. His cage door is always open, and he can fly in and out of his cage anytime he wants. I think that it would be best if I keep him with another dove of some kind, 'cause doves are not really aggressive animals, and aren't very territorial. Although, I do know that two male doves will fight with each other over a female and that mourning doves are more agressive. I'm planning on purchasing a miniature ringneck dove as a companion for my diamond dove. I think that he would be happiest with another dove as a companion. Although, I was wondering if there would be any problems with keeping the two together, since they're different speices.
