Knew I had to have missed a few,until you posted that couldn't even picture one at Yorkshire Wildlife Park,now that I have looked at my photos of the place I know why I couldn't remember it!!!And thats because its as dull and boring of an exhibit as the one at Black Isle and that is not a good thing to say about a Park that I rate highly!!Yorkshire wildlife park has one too.
Update from today!;
1)Two L'hoest Monkeys have gone on-show in the Island enclosure next to the Pileated Gibbon.
Wallaby and Kangaroo walk through enclosures in the Uk off the top of my head are,
Banham Zoo ? (Used to have one not sure if they still do)
Black Isle Wildlife Park
Blackpool Zoo
Colchester Zoo
Dudley Zoo
Lakeland Wildlife Oasis (Used to me free roaming in the outdoor section)
Marwell Zoo
Newquay Zoo (Used to have a pair of free roaming Parma Wallaby)
Paignton Zoo
South Lakes Wild Animal Park
Twycross Zoo (In the new pets corner not always open to the public)
Whipsnade Zoo (Free roaming inside the park)
Wingham Wildlife Park
Woburn Safari Park
1:1 Kea taken off-show
This might be old news, but it was a very pleasant surprise for me ... Blackpool now have a pair of L'Hoest's Guenon in place of the smaller colobus group on the islands near the entrance (the main group in the primate house is looking as good as ever). They came from Edinburgh and are currently confined to the house: obviously they will need to be introduced to the island carefully having had no previous experience of water barriers.
One of them came from Colchester they arrived in the summer.
