I have been thinking about this question. Islands is still very much in development and I expect to see changes when I visit again today. These may be deletions as well as additions - I was happy to hear that the python sculpture has gone

but of course it may reappear

I think that once the last animals are settled in (be they orangs, tigers or babirusa) we ought to open nominations for two polls to find the best and worst features of Islands. I will try to photograph some of the elements which have not yet been featured here, and there are quite a few in spite of the best efforts of ZooChatters over the past few weeks. The scale and detail of this development is hard to grasp.
