The Goosanders usually winter on Bretton Lakes and then move on during early spring. However this year there are a few stragglers.
This female had a mate nearby and appeared to be either looking for a nest site or visiting an existing nest in a tree on the island. Hopefully they will breed and we'll see some young in the next few weeks.
I came across a pair of Treecreepers building a nest under this flimsy looking piece of bark on a dead tree. This one eventually worked out how to get this long twig through the narrow opening only for it to fall out several seconds later!
