The Amphibian exhibit in the AZ Aviary has now been changed to a "Diversity in the Desert" exhibit. It holds snakes, lizards and amphibians.
A huge improvement. Although there is nothing wrong with frog exhibits, it bothered me how they had all these frogs and toads from all over the world in the middle of the Arizona Trail. Now if they can just return bald eagles to the large aviary instead of andean condors, the theming will be appropriate throughout.
