I'm new to this game, so I'm picking up on lots of old threads. Phascogale September 2013, thanks for reminding me of the Ankole Cattle I'd completely forgotten about them.(I love their German name Watussi Rind.)
I confirm that there were definitely European Bison as well as American. My memory is that there were both Dromedaries and Bactrians; don't remember the Blackbuck at all. I must have seen the Antelope House, but was too young to remember it. I believe I saw the same enclosure when for a short time it was an Australian Paddock, and on another occasion I believe it contained zebras.
Have a very distant memory of a Maned Wolf in the D & C, and I believe a hyena, again too young to appreciate which species. These had presumably been transferred from the North Mammal House, where I remember seeing hyena & cheetah.
I have a 1954 guide book which contains a colour print of the Antelope Paddock which on that occasion contained Eland, and what looks like Grant's Gazelle. The guide mentions that the Antelope House contains "rhino" and Grevy's, Burchell's and Mountain Zebra, these being temporary quarters pending rebuilding. There is also a reference to the Gazelle Sheds, of which have no recollection whatever.
One of my favourite memories of a rarity is in the early 1960's of a Wolverine in a series of detached cages which were replaced by the Flamingo pool.
Oh for a time machine - and don't start me on the Monkey House!
