On Christmas, a 4 year old Siberian tiger named Titiana managed to escape her outdoor exhibit at the San Francisco Zoo and mauled three men. One died.
Investigations are being done into why she was motivated enough to leave her enclosure, not an easy task, and maul these men. Some spectators are saying they provocked her, but this has not yet been confirmed by AZA or the zoo.
In the course of the events, police shot and killed Titiana. This is a very sad loss for the conservation movement, as she was just coming into her breeding age, and could have produced a litter of 3-4 cubs every 2-3 years. For a species that is Endangered, breeding programs are critical.
I am in a state of shock at the moment, saddened by the loss of one man's life and the loss of such a beautiful creature.
I plan to keep checking the zoo's website, for updates to this situation. If you are interested, you can visit the zoo's website http://www.sfzoo.org/ and the Association of Zoos and Aquariums website http://www.aza.org/ for information.
Here is the zoo's page on these creatures, in case you want to know more about them.
