Pardon my ignorance - is there any specific reason they needed to be kept in/fenced from that yard in specific?
Were the elk and reindeer still signed at their respective exhibits?
Is the agouti signage gone? I suspected it had left as I made three visits last year with no sign of the animal. Sounds like lemurs are taking over SMH - they probably still have some callimico behind the scenes as they still had multiple last September. I think they've only had one GLT there for a bit.
Glad to hear they're doing work on the AARC and super glad the fly river turtle is doing well. I saw the animal in September after missing it on both summer visits and worrying it had passed so always a little more worried about that one.
The laughingthrush/hornbill combination could be interesting, though I share the same concern/suspicion as you, gives me a bird to watch out for!
