Everything is Permuted

The winter light is so good that inevitably I gathered several more photos today. Regular visitors will recall the somewhat blurred shot of a lapwing from Tuesday's post. Well, I had another sighting today, in more or less the same spot. This time though I was able to track it as it flew overhead and although far from the best b-i-f (bird in flight) I've managed, at least it's in focus this time.

There were plenty of the more common local birds in the vicinity, including this crow which flew past while I was surveying the fields from an excellent raised vantage point.

And I can hardly ignore the robins, which seem to be falling over themselves to get in front of the camera at the moment. This one seemed quite intent on being noticed.

The final shot tonight is more of a reference photo. I was unable to get anywhere near the subject, but spotted it in the distance and took a few frames as I tried (unsuccessfully) to get within proper range of the lens. Nothing particularly unusual about the species. It's a rabbit, and we have countless rabbits around here. What made this one special though was the colour. It's a black (melanistic) variant, the first such one I've seen in the wild. Melanism, is a pigmentation variant caused by an excess of melanin (logical) and is occasionally seen in foxes, squirrels, rabbits (evidently), and cats (among other mammals). The photo is heavily cropped.
