Pine marten (Martes martes) adult female portrait, standing, in caledonian forest, The Black Isle, Highlands, Scotland, UK, July. Photographer quote: "Sitting alone in my hide for hours on end, you begin to question the wisdom of why you do this. And then, a scratching sound heightens the senses. Moments later, my quarry appears. These super-sized stoats are returning to Scottish forests where they havent been seen for decades, the result of legal protection and increasing woodland cover." Did you know? Pine martens are related to otters and stoats and eat a wide variety of food from birds to berries.
