Frost and Fog on Snow and Ice

Morning sunrise, deep frost, nippy on the skin, beautiful to view. Then engulfed with fog which has ebbed and flowed across the landscape. As the blackbirds retrieve haw berries from the tree and the ground I wonder if its liking eating frozen peas, do they chew them somehow to extract the goodness? Wondering how that works. I've put more seed out for them. There's a weak sun trying to break through to warm a few parts of the ground but there are some areas which never catch the light at this time of year.

To the south and east we have blue sky, to the north and west there is deep fog, wonder which will win out today? Loch Lomond is immediately north of us and the moist air above the loch often creates a dense inversion layer, very pretty to view from the Dumpling (hill pictured below) when you see the hills in full sun rising out from the dense white/grey fog.
