Don't forget the birds...
If you're in this strange snow-bound world that we call the UK, don't forget our little feathered friends. Fresh water, fatty foods, seeds etc etc will all help them through. Don't bother with bread and you're better losing the plastic nets that peanuts and fatballs come in - they can damage birds' feet.
The snow seems to have brought a few new visitors to our garden. We had a woodpecker at the nuts yesterday and as I type there are three redwings up in a tree, eating snow. I've never seen either in the garden in the ten years we've lived here.
One thing I have noticed about the snow is a resurgence in walking. People are wrapping up and trudging their way around the city - maybe the habits will stick for a while.
