It seems to me a conure aviary next to the Encounter Village looks very much the better in this place, esp. next to Wallaby area. Would be nice if they took in some further Antipodes heroes (tree kangaroo, koala, rat kangaroo, echidna, wombat ....

).
Same, I would like to see some more Asian species and perhaps a less haphazard zoning (either zoogeographical or by habitat ... it is even to me).
Marwell would certainly benefit from some more indoor exhibits too.
(alas that will cost a lot of budget which perhaps they may not have at their disposal).
I am really not too negative on Marwell as it stands - even though it has been a hoof stock stallwart before exemplified by large breeding herds of hoof stock. Whether those days will return .., I think not.
