my allotment has a healthy shrew population. unfortunately I only know this because I have found several dead shrews: two last year and another three in the past month or so - I think one of the two I found last year was a pygmy shrew.
but what I don't understand is why they're dying, and the weird places I find their little bodies in. each one has been in the middle of an area of open ground, either in the middle of an empty vegetable bed lying on the bare soil, or in the middle of an area of carpet laid on the ground to suppress weeds. they have all looked perfectly intact, too, with no obvious signs of having been attacked by something.
I can only guess that either they're reaching the end of their life cycle and are dying of natural causes (but I think it's odd that they're doing it in open ground) or that something is hunting and killing them but not eating them because they don't taste good. or, would the weather have anything to do with it? I seem to find them when it's been raining...

any ideas anyone?!?
