O.K. Patrick, so we agree that the hamadryas baboon enclosure is an eyesore, and that the mandrill enclosure is good (yery good, in fact), but let's not ship everything out to the backblocks just yet. When you say that the baboons are underappreciated I assume you mean by zoo authorities - they certainly are appreciated by the public any time I've been there, although THAT enclosure certainly cops it's share of criticism.
backblocks? see, i wouldn't call werribee the backblocks. nor do i think its necessry to have two baboon species at melbourne, especially when the larger group of the two is housed in a substandard enclosure. and i disagree that they are appreciated by the public. the enclosure smells bad, the feaces is obvious due to the concrete floor, it has very little height to it and rusted wire front. its unattractive and its suitability for the animals is (whilst in my opinion, lousy) irrelevant. its an eyesore to the public and moving them should have been a long standing priority.
if the baboons left for werribee they would
a) provide a new, much needed attraction at the park
b) be afforded the space to be housed in a manner that would give them maximum appreciation value. baboons work best when you can see troop dynamics clearly. this isn't so obvious in small cages.
c) remove the need to create a large space consuming exhibit at melbourne is better focusing on other expansion of existing precincts in which the baboons do not fit in thematically.
d) free up those baboon cages to temporaily house species that would be more suitable. with all the development going on, the ability to "shuffle" species is very important. if the concrete is jacked-up and the cages planted out, they could easily suit small cats or smaller primate species short term.
of course, it means setting aside money, and there are three other species living in unsuitable enclosures in melbourne in my opinion... bears (to be phased out), batchelor gorillas and seals (to be addressed shortly).
