I was fortunate to see the animal on two different visits while working on my book Zoos of the Southwest. Last visit was November 2013 - just a few weeks before Taz died.
@Arizona Docent I know of at least one zoo (can't name it) who was legitimately offered some, but they declined due to not having had a very successful history with duikers in the past.
@ThylacineAlive I would love some more info on this if you can share anything. Im not looking for names or anything, but its one of my favorite species and an interesting conservation case.
