Nibbled nuts!

I seem to remember hearing that small holes, like these, in nutshells are left by the Dormouse; other species leave more damage.

Dormouse unlikely to visit a garden shed? Holes more likely made by Wood Mouse (Bank Vole holes are neater). The split open shell on the right is more characteristic of Grey Squirrel so there may have been two different nibblers

Two nibblers?

The evidence is never quite as clear as the diagrams suggest!, but looking at p12 of http://www.erccis.co.uk/OneStopCMS/Core/CrawlerResourceServer.aspx?resou... (I think a link to this handy guide has been posted before), I would agree that the nibblers are probably (wood) mice and a squirrel.

The hording of nuts in a single place is also a good sign of wood mice
