Part of the Mandrill exhibit at Colchester 29/11/09

This sounds about right
I remember when the cheetah were kept where the dik dik are now, this site was also home to the red river hogs after the cheetah. The mandrill used to be where the meerkat enclosure suricata sands is now, this was home to the stork group after the mandrill!

Thats right. The cheetahs now have a much better and much more spacious exhibit now than they did then.

Thankyou Goretex for that clear timeline.

I didn't realise the most recent enclosures are already about six years old.

Colobus enclosure finished early 2005 as did the cranes and red river hogs.

Press Information: Colchester Zoo's group of Colobus Monkeys move to new enclosure

But I got this information from looking through my photographs. The Black and white colobus monkey enclosure had definately been built by 2004 as I havve photographs of them then look in the gallery I've posted a picture. And I'm sure I have some from 2003.
