I don't normally take images from the "captive" pens at Slimbridge, but thought I would have a go to warm me up before venturing into the "wild side"! Below are some of my favourites:
Common Eider (Cuddy Duck or St Cuthberts Duck).
I love seeing and hearing Cuddy Ducks - their call always reminds me of elderly lardies watching a naughty film or even reaching an ongoing orgasm!
Maybe this is what the elderly ladies were watching in order to sound like Cuddy Ducks!
