I think hybrids are wrong to create as the effort had just begun to pump up the wild populations and restore genetic diversity.( think spix, buffon's, scarlet, hyacinth, lears) . HOWEVER they now make SENSE due to the overly restrictive cites rules for macaws. Get a purebred who is classified? Or a hybrid that "doesn't exist" or matter in the CITES restrictions? Sadly, it's becoming a practical to go with a hybrid.
During the first half of 2015, our Avian Vets, as a group, was involved in getting changes to the CITES rules to allow transport of Classified Endangered Parrot to be transport within the United States for the reason of assuring the DNA strength of the US population. That effort was strongly stood against by groups who have long stood against the ownership of Parrots.
This subject will again be raised in 2018 and our Avian Vets plan to again work to lift the restrictions that have and are resulting in inbreeding. At present, the 2018 CITES review will be opening for adding yet more MACs, in addition to other Parrots.
If you, as an individual, have a position regarding CITES, please pass it along to your Avian Vet.
