I feel for the birds when the temperatures plummet. I’m feeling cosy in hand-knitted woollens, fleece-lined trousers and wind-cutting jacket, whereas all they can do is fluff up their feathers to retain a layer of warmth close to their skin. It seems to work for them though, as long as it doesn’t get too cold. And little birds like these Robins are even more adorable than usual when they look like little balls of fluff.
