Our family Robin

Every winter, our family Robin Redbreast returns in our back garden.
He knows us so well that we can walk through the garden without disturbing him.
He even comes near up to 7 feet to see what I am doing when working in the garden as winter preparation, before real winter starts.
He did not yet knock on our backdoor to beg for food, as we provide enough for the birds :-))
As it is a territory bird, it defends our garden fiercely against intruders.
We are not sure, but we think that it is the same bird that returns every winter, considering its behaviour.
