Hi. I have had a pair of diamond doves for about 4 months now. The female has a crest on the back of her head. She is very beautiful. I had a friend come to see me and he told me he has never seen a diamond dove with a crest before. I looked on the internet for pics, but there does not seem to be any mention of a crested diamond dove! It she unusual? I also keep ring neck doves and some of them have a crest too. The diamond dove definitely has a crest - its not in injury or damaged feathers. Can anyone tell me if she is unique - or do crested diamond doves exist? I can try to post a photo if anyone is interested.
