Beautiful Major Mitchell, Marcy. They're my favourite cockatoo, and no exactly cheap even here in Oz. Where I lived over east until Feb, there were 3-4 pairs that bred around town, they'd sometimes come into the tree in my backyard or at the office (which was on 7 acres, with some acacia trees which many parrots love the pods of). I've also seen them in the wild on the Nullabor Plain including most recently in February as we crossed to come over to the West again.
A friendly acquaintance who we got several birds off on my last town (mentioned above) had a couple of pairs of MMs I must email him to see if any actually bred. Last summer he handraised 4 chicks for a friend of his so I got to see the babies close up.
I see an Alex in here and you have Bella- we have a female eccy called thus (not tame). I doubt a MM would fit into our zoo, now, as we'd be unable to give it close, one-on-one attention.
Once again, a simply beautiful bird, Marcy.
