Blackness

Managed to totter to the car and drive off to Blackness Castle in time for coffee. But the castle was shut :-[ so I bravely went for a short totter along the beach and then across to the grass on the other side of the castle grounds. And had a coffee when I got back home.

This is a raft of Eurasian widgeon, or it could be a coil, company, trip, flight, bunch, knob of widgeon, according to this site (thanks DaveH).
