Is this on the original side, towards the Paddocks side? When I visited in 2006 they where on that side, however i do not know about past swappings from enclosure to enclosure etc.
They have swapped since then around 2007 ish to their present enclosures.
For some reason the enclosures apear alot more spacious back then, must be because of how bare they are, as they would only of been in use for a few years when this photo was taken.
