Have you had them before or is this just knowledge you picked up?i bet you would do more harm than good. They have problems with them getting trichomoniasis. Breeding them and potentially getting sick and mingling with native populations wouldn't be good for em. Besides they only raise one squab a year. Wouldn't be doing a whole lot of breeding.
I've only wikipedia the family/genus... and was looking on craigslist but nobody has anything.
I was trying to see if I could pair up different but related breeds of New World pigeon to try and recreate something like the passenger pigeon. Kind of like the Tauros Project they are doing to recreate the Aurochs in Europe.. .
