Shovellers seem to spend almost all their time in the water. Usually they are swimming round in tight circles, filtering the water just below the surface for food. When they take a break, it’s by relaxing and floating where they are.
For once, this pair of shovellers had climbed onto a fallen bough. They were standing one-legged; their necks turned so their heads were resting on their backs. Their eyes were open, or at least the eyes visible from the shore were. But they may still have been asleep: a neat duck trick.
