Last week I gave you this skeleton fron the Dead Zoo to test your identification skills:

In retrospect I think I was a little unfair with this one – the photo is not very clear and there is no scale bar, so the identification relied mainly on the context provided by the mount and a lot of deduction. Not an easy task with a rodent, since there are so many different species.

The branch used as a setting for the skeletal mount provided the main and most important clue – it indicates that the species is arboreal. A lot of people picked up on this, with guesses ranging from a flying squirrel to a viscacha. However, the answer is something from a bit closer to home (i.e. Europe).

This is the skeleton of the Edible Dormouse Glis glis (Linnaeus, 1766), a plump (and presumably tasty if you happen to be an ancient Roman), tree-dwelling rodent, with a reputation for somnolence.

This isn’t the first time I’ve featured a dormouse in the blog, although the previous one was a giant extinct example. The Edible Dormouse is the largest species alive today, but it’s still smaller than the fairly diminutive Red Squirrel.

They are fairly well distributed around central Europe, with a small population in Southern England due to escapees from Walter Rothchild’s menagerie in Tring in my home County of Hertfordshire. I’ve heard tell that they can be a bit of a pest in the area, due to their habit of seeking out attics to hibernate in, but then chewing through wires and cables, thus causing fires and broadband outages.

This UK population didn’t arrive until the early 20th Century, so the species that inspired Charles Dodgson (AKA Lewis Carroll) to include his sleepy character was almost certainly the smaller Hazel Dormouse, which occurs in Britain, and which also turned up in Ireland around County Kildare around 14 years ago (and which we have specimens of, thanks to a gift from someone’s pet cat).

I should have either provided a better image or a clue to point you in the right direction for this mystery object, so I feel I’d better apologise for setting this vexatious conundrum and promise to better next time!
