Given the state in which P.t.corbetti finds itself in the wild, I find this animal more than usually depressing. Maybe I'm being a killjoy, but Thailand's native Tiger surely needs all the zoo space going.
pure white tigers, or pure Bengal tigers which were white?
I saw three white tigers at the Assam State Zoo (Guwahati) and one at the Alipore Zoo (Kolkata). I assume they were pure Bengal, being in India, but I don't know for sure.
I suspect all or nearly all Tigers( normal and/or white) in Indian Zoos are still pure. I wonder what the chances of ones in e.g. Thailand such as this one, having either come directly from India too, or bred from Indian imports, and therefore being pure also?
the white tigers at Zoo Negara in Kuala Lumpur came direct from India: http://www.zoochat.com/654/white-tiger-352084/ (I completely forgot about them when answering ThylacineAlive above).
