Bruce, the short-beaked echidna, has been moved to the newly revamped Nocturnal House. He's on the side that used to hold fruit bats and, more recently, meerkats. He was asleep under his lamp on my first visit, but moving towards a hollow log on my second. The sign seemingly suspended in mid air is a reflection!
In a recent BBC nature film about Australian wildlife, the most memorable sequence was an echidna walking across a snowfield in the mountains in broad daylight. Of course the species has a very wide range in Australia, and I have no idea of Bruce's original locality.
I've only ever seen him in the winter months - the first time in January 2012 and the second time in December 2016 - and he was constantly active on both occasions.
