Washing his Mittens
And it is a 'he.' Captured through the window. I have my Fuji 100-400 mm lens waiting on the floor for just such an occasion. His companion was perched nearby with his back to me.
Of course, I had to release Basil to chase them away. It's a game. Basil always rushes the wrong way to the pond which gives them time to leap off through the woodland.
I thought he might be chewing a nut or seed, but enlarging the photo suggests that his front paws are damp, possibly from cleaning himself.
It did snow, but stopped as I emerged from the shower, so I was too late to walk out in it and take photos. Look carefully and you should note three streaks in the top left quadrant. Blue sky now.
