Country diary: I looked into the eyes of Britain's most savage killer

Aigas, Highlands: The weasel may be tiny, but this fierce predator can dispatch and drag off a full-grown rabbit 25 times its size - and has a stare that even humans can find unnerving

If I asked you to name Britain's most savage wildlife killer, you might say fox or peregrine or goshawk, or perhaps even the golden eagle or the Scottish wildcat if you knew about such exciting rarities. But I think you would be wrong. Savage and killers they all are, no question, but in my book none comes close to the smallest UK mustelid, the weasel, Mustela nivalis, so tiny that its skull can pass through a wedding ring.

A few days ago I watched one hunting. It vanished into a rockery and emerged a few seconds later with a vole dangling from its jaws. Voles, rats and mice, as well as small birds, are a weasel's staple, but a male will take much larger prey such as a full-grown rabbit, up to 25 times its own weight, kill it, and, incredibly, drag it away into cover. No other British predator does that.
