I do like this aviary, a nice big aviary for a pair of cockatoos. There is another photo on here showing macaws in here in the 70s or 80s.
The leopards and jaguars were kept, at least the most recent ones, in relatively small, thich-barred cages. These most recently held the Asiatic golden cat, before being demolished for the new otter enclosures. I don't know for sure that this was where the black jag lived however, but it probably was.
Oh! I wonder what this means. I'm somewhat concerned now, hopefully its just for routine maintenance. There is nothing on the AZ website about it.
Incidentally, AZ are phasing out all there pheasants, including the Himalayan Monal that were in this aviary. Did you see any on your visit? There are normally Reeves' with the lovebirds and anothe species further up with the parrots.
