-There are now 2 white rhinos in zoo center at the bronx zoo. They are where the indian rhino used to be which was origionally for elephants. They have the former elephant yard which is a good size for the two rhinos.
-The spiney forest part of madagascar is now netted over. It ruins the view but it is still a great exhibit.
The bronx zoos is not really a city zoo its 265 acres. I have posted pictures of there indoor habitat in the bronx zoo gallery a few days ago. It basically a concrete floor covered in part by hay with to side sections that can be separated. Its not pretty but is functional and has a nice outdoor exhibit.
I don't know why they would do that with the spiney forest. Also, it would have been really cool if they got black rhinos instead as that exhibit is perfect for them. White rhinos would work better out on the African Savanna exhibits.
