A very attractive species, albeit one which is liable to infuriate me before too long - although Stuttgart holds the species, I believe it is one of the many species going offshow or leaving the collection as a result of the imminent demolition of the bird house and small mammal house. As such I am likely to miss the taxon when I visit Stuttgart next April.
I've seen them at Stuttgart, and at that point they certainly were in that little bird house. I'll miss those buildings - not the best ever, but reliably interesting!
