Puffed up singing Robin

Normal working day today and there's more people in the office. A cold day today with a keen wind, so I am well wrapped up for my ride in to work, and for my walk at lunchtime.

As I was walking back to the office I came across this robin singing away. He must have been cold, as even though I was quite close to him, he preferred singing to flying away. At least us humans can go inside.
