As you'll know if you've been following my blog for a while, there are two local animals which I see an awful lot of, despite them being rare in most of the UK. These are red squirrels, Sciurus vulgaris,(which there are loads of around here), and pine martens (which are hard to spot, but I have lots of trail camera footage of them).
Despite them looking slightly alike in the photos above, and both living in trees, they are completely unrelated. Squirrels are part of the rodent family (which have two sharp front teeth, with an orange outer edge), which also includes mice, voles and beavers. Pine marten are bigger, about the size of a small cat. but are from the mustelid family which includes weasels, otters and badgers. But there's one unusual link between them which not a lot of people know about.
