Bird Watch walk

The last Wednesday of every month is Bird Watch walk at Castle Espie and N is usually there. I'm usually elsewhere, but today I went bird watch walking too. These birds are in the captive collection, an Eider duck and a pair of Buffleheads. The Eider are my favourites, I love the colours, and they make a lovely sound too. 
That's my second visit to Castle Espie this week - I was there on Monday too, for Generation Wild.
