The india blue is extinct as a species in captivity in the United States because of hybridization. Sure you get some that are superficially "blues" but often times you can see the result of Spalding heritage in the form of coal dusting coloration on the front of the wings. Wild blues look nothing like anything we have here. Green peafowl are rare but hanging on because a few dedicated people are keeping the best ones away from people who would mongrelize them. Green peafowl are endangered, congos probably are too, we don't need to compound that by mismanaging them for the purpose of making curio birds.
