I’ve not seen a Robin do this exact thing before; I assume it was sunbathing (probably to drive out parasites).

First noticed a ‘ball of fluff’ sitting on the fence and thought it may be a sick bird. However having watched it for a few minutes it became apparent this was deliberate behaviour. It would turn its back to the sun, ‘open’ its feathers and sit like this for a couple of minutes. Then followed a good scratch and a bit of a preen before repeating the entire process. The photo is the same Robin when he realised I was there and returning to normal.
