A Robin’s territory: Robins are one of the few birds which hold territory all year, which is why we hear them singing throughout. But this is the time they get really aggressive, even fighting to the kill sometimes. While draining the pond, I watched some territorial behaviour (on average they hold about 1/6th of a football pitch for
breeding.) Every now and again I heard a flutter of feathers and there was the Robin, a couple of feet away, eating insects as they became exposed. Then he, and I, would hear another Robin singing and off he’d fly, visiting the extents of his territory and, when necessary, flying up in a tight spiral with the other male until one withdrew. The red breast is thought to be entirely for territorial purposes, acting like a bright flag, for display. Conditions: A cool, still, grey day after days of ice and sunshine. Temperature: Max 6- Min 4c.
