Most gardens in Britain will be visited by or little robin. They're so tame that I can recall occasions when I was digging the ground with a spade and almost trod on a robin under my feet. I've known robins that will hand-feed and at the reserve where I took this shot, a robin use to perch on the sill of the hide while I was taking photos.
Whilst very tame, they can also be incredibly aggressive towards other robins - I once saw a couple of robins rolling around on the ground like mud wrestlers. I've also heard that they are not so tame on the European continent. The robins in our garden during summer may not be the same robins we see in winter, as there is a significant influx during the cold months.
There are very few days that I don't hear or see a robin, and I usually manage to photograph at least one robin on any woodland visit. They've become associated with Christmas and feature on many of our Christmas cards. No wonder they were voted into as our national bird.
