Pine Marten - a female that visited the woodland hide that a friend has set up. She's so alert and beautiful.

Thank goodness for silent cameras. Taken with my Canon R5 and RF100-500mm, here in the Scottish Highlands.

@petewalkden lovely creature.
I gather they are also good at preferentially predating grey squirrels, which is why you still have some reds.
@marjolica I don't think the greys have reached these parts yet, but you're right, pine martens do seem to keep them away naturally.
@petewalkden @marjolica the appearance of pine martens in the central Borders is definitely associated with a drop in grey squirrel sightings. Anecdotally at least. Also coincident with the first time I've detected a red in this particular woodland.
