There are two tigers visible in this photo, and this exhibit is one of the newest additions to an otherwise hit-and-miss zoo.
An excerpt from my 2010 review:
Realm of the Tiger – This exhibit complex only just opened (April of 2010) and it is part of a $5 million renovation/overhaul of the central section of the zoo. There is an Asian-themed entrance, a courtyard and a gorgeous little pond, and then 4 main exhibits. A Sumatran tiger enclosure is far too small and lacking shade, a Malayan tiger exhibit is about 3 times larger and much better but still short on trees (I’m not sure whether the zoo rotates the tigers or not, but it seems possible), and there is a mesh siamang habitat and a pleasant walk-through aviary with Asian birds. The highlight of my visit was being a few feet away from 2 out of the 3 tigers as they lay panting in their pools.
