Two Kingfishers were fighting beside the river this afternoon. At one point, one of the birds was thrown into the water by the force of the impact. The whole episode was accompanied by loud piping and I assume it was a territorial dispute. A little further on, two Nuthatches and six Goldcrests were moving through the trees with a big tit flock (although the two Nuthatches seemed more interested in posturing at eachother).
