Eider
Somateria mollissima
Both pictures were taken at South Walney. The female (left) is on her nest I think, but I didn’t want to stay around too long to find out.
The Eider call has always made me giggle a bit – have a listen below. It reminds me of Kenneth Williams in the ‘Carry On‘ films. Childish, I know, and my apologies if you’ve never heard of him!
