Great find. I haven't been to the Bronx Zoo in ages. The last time I went the Tigers were still exhibited on a tram ride that went around various Asian exhibits.
They still have tigers on the Wild Asia Monorail too, but the main tiger exhibit is the Amur tigers at Tiger Mountain.
I posted some photos from the tiger enrichment at tiger mountain last weekend if anyone is interested
Tiger Mountain is a brilliant attraction, and a candidate for the best tiger exhibit in North America. I'd still rank the Minnesota Zoo as #1 in that category, as it has the largest tiger enclosures and the 2 habitats there are enormous. One area is thick forest while the other is entirely naturalistic and more of a typical zoo tiger enclosure.
