For those interested in a visual history of the zoo, there is now a series of DVDs in the gift shop ($9.99 each), re-recorded from VHS tapes that they used to sell. They were produced c. 1990, and are about 30 minutes long each. They include "Zoo Adventure" (a basic tour of the zoo), "Zoo Secrets" (a "behind the scenes" look at some of the different departments), and "Zoo Babies" (self-explanatory). Some interesting footage of the koalas when they visited in 1988 (in what is now Malayan Woods), the African paddocks area before the savanna renovation, and a whole bunch else. There aren't any huge revelations, but it is a very interesting look.
