Sadly these are now gone and it is basically just a frog exhibit. (There were a couple mallards after these along with a small owl, but I did not see any of those today either). Just a very common mourning dove and tons of frogs.
Yes, the first large exhibit in Life On The Rocks is what I was referring to. I assumed this was taken there. However, I never go in the walk-in aviary so it is possible this was taken over there, in which case they may still be there.
