I was able to add a couple of hours at the zoo today onto a work trip before I head home to Australia, and as usual I spent most of it with the nocturnal primates (since they're what I most miss about living away from London).
The aye aye and mouse lemurs were all active and visible - the aye aye in particular - and with 90 minutes downstairs I was able to get good sightings of the potto, both loris species and both galagos. Such a great collection to have in one place. As ever the lorises were much harder to see than the galagos, but with patience more than one emerged. The potto remained hidden for over an hour, but to my delight started moving around shortly before I head to leave. (I remember there being two pottos, but only saw one today. Are/were there two, or is my memory deceiving me?)
I had just long enough for a brief walk around the neighbouring African mammals on my way out. Very sad to miss Thug by just a couple of weeks, but Amara looks like a beautiful replacement for Nicky. I saw one okapi, but no duiker; are they still housed together? (The okapi was actually stretching its head over the hedge to get scratched under the chin by a guest...I don't like seeing visitors do that, but the animal was clearly not distressed - exactly the opposite.)
