One of the things that I love doing, but which I don't seem to have got around to, is small-mammal trapping. Part of the reason is the lack of a local shop selling castors (maggot pupae!) which I put in the trap to feed any shrews that wander in (a legal requirement). Here on the West Wight the tackle shops only sell ragworms and lugworms which look like they might eat any shrews! :-)
A week or so ago, I found evidence of rodent activity in our garage: seed eaten, cardboard chewed, and things knocked off a shelf onto the floor. I set up a couple of Sherman traps and, on Saturday, found this leggy Wood Mouse in the trap I'd set half-way up a bookcase!
