You can tell what is feeding in the Wildlife Watchpoint Mouse House by looking at the mess left behind. Wood Mice shell the peanuts, leaving the shell intact on the floor, and then run off with the nice white nut. Bank Voles simply rip the shells off in the bowls and leave lots of bits in the bowl. Common Shrews don’t bother shelling the nuts – they just take the lot.
This photograph by Mark Walpole shows one of our Bank Voles leaving a bit of a mess after a Sunday lunch.
