Good luck, getting these birds will be a challenge. Most probably he will make more chance if he s prepared to swap birds, because there won't be many people preparing to sell. Or if so for quite a sum of money. I saw your friend was also looking for the bird in avicultural circles. I know 2 males from Cyanocorax species for sale, but then he ll be stuck with 3 species for which he looks for a partner.
