Goldeneyes are graceful diving ducks that can stay under water more than one minute. Difficult for a birdwatcher, because just when you see the bird in your binoculars view , it dives down to come back meters away. Fortunately, the Goldeneye is recognisable by a white spot on a dark green head (male) or a grey body with a dark brown head (the female). Mostly they are seen together.
