The scoters were fascinating to watch as they packed tightly together bobbing up and down on the surface of the water before diving in synchronous one by one following each other and completely disappearing under the water to feed and then appearing on mass.
Eventually I picked the black scoter up with its bright yellow bill glowing in a short spell of good light.
I spent the following morning at the mouth of the Ythan Estuary trying to relocate the king eider, but with most of them now entering eclipse plumage the odds were stacked against me and as nick said it had probably moved on anyway.
