The weasel is small. Really small. Much smaller than most people realise. It is not only the smallest mustelid, it’s also the smallest carnivore in the world. Growing to between 13 and 26 cm in length and weighing as little as 25 grams in some cases – about the same as an AA battery – it is a mere 0.0025% of the weight of the planet’s biggest terrestrial carnivore, the polar bear.
When I was young, the first bird of prey that I was able to easily identify was the kestrel. I suspect the same is true of many other people. The kestrel’s silhouette, suspended in the sky as if by wire over some heathland or motorway, became instantly recognisable to me, for no other British bird of prey can hover in place with such utmost precision.
