Thank you! I have to admit to a slight 'cheat' here: it was feeding time, and the keeper very kindly asked me where he might place the food to make photography easier... so all my photos of this individual were taken while he was searching out his meal (which only took a few seconds, of course)
I spent the whole morning down in the carnivore section, but didn't see anyone else (apart from keepers); I don't think many people make it down that far!
