Was the Woodland Park Zoo a good zoo for photography? Not so much for me yesterday. It was difficult to set the animals against a natural looking background and many viewing areas have hand smeared glass between your camera and the animals. One positive feature was that some glass viewing areas had glass that was leaning away from the viewers. That can be nice for casual photography because if you use a flash, your flash won't reflect back at you. I can imagine it would be better if the animals in some of the open air cages were closer and more active.
