Takeaway for the kids tonight.

Can anyone explain why the British Robin is so comfortable around humans?
Of all the wild birds in the UK, these guys approach much closer and with no apparent fear. They are very territorial. This is one of a pair nesting in our neighbours garage. We treat him to his favourite snacks: mealworms. These are the dried variety but still seem to hit the spot. He has to eat them quickly. Our dawg is up for any extra food.
