Siskin. Wollaton Park. A small flock feeding in the Alders by the lake.

 

 

Herons nest building in the fallen Willow of the island on Wollaton Park lake. I was absorbed watching these. They (I presume the male bird) clambered among the branches deftly stretching out necks to pluck the wiry willow stems and flying back to present this prize to the mate waiting in the nest. Fascinating birds.
