SF Zoo has a single Amur female and what is now a breeding pair of Sumatrans.
I was looking @ the Woodland Park Zoo's website in anticipation of my first ever first to Seattle, and it looks their Sumatran is off-exhibit. Yet, the new plans are calling for Malayan tigers? Any idea where the Sumatran is bound?
And they have a new tiger cub at San Francisco!
The last Sumatran at WPZ died, and Malayans will be an upcoming attraction in the new Asian Rainforest exhibit coming in 2015.
