Bird

This bird is actually quite small, although it gives the impression of being big in this picture.

I was standing in the back garden, watching this bird and it's partner attack a much larger bird, as it was sitting on a tv aerial of a neighbouring house.

They would attack, then fly over to my house, hover, then fly back for another attack. Eventually the larger flew off for a while. Then it came back, and the attack started all over again. Eventually, it gave in and flew off, and didn't return. And then the little birds flew off.
