@dean - This is a mixed exhibit for Lammergeier, Alpine Marmot, Alpine Rock Thrush and Red-billed Chough along with the base of the aviary and the lower right-hand side, where I took this photograph, there are further viewing points into the aviary at the rear and top of the aviary; this is where the photographer to whom you refer is standing, and also from where I took the following photograph:
I discussed this exhibit in more detail within this post of my walkthrough account for Alpenzoo.
Thanks for that TLD I don't always have time to keep up with zoochat and enjoyed reading about your trip. I too like aphibs and reptiles and keep both alpine newsts and yellow bellied toads, in fact i bread over 70 yellow bellies this last season.
