Long-tailed Duck male (Photo: Saulius Karalius, Fund of Lithuanian Sea museum)
Of all the ducks wintering in the Eastern Baltic Sea, Long-tailed Duck has one of the most impressive tails. Its tail has very long, slender central feathers.
Long-tailed Duck changes plumage of some body parts up to 3 times per year whereas most of other ducks moult only 2 times. The plumage of this duck differs depending on sex, age and season.
In springtime they can be easily traced by their quite nice voice. When they group together, it seems as is all the sea is singing.
This duck is a splendid diver. It usually dives 10 metres deep to the sea bottom while looking for molluscs and crustaceans. During daytime it spends more time underwater than above it therefore it’s quite a challenge to get a closer look at it. But they usually winter in large flocks of several thousands of individuals. So if one got away from your site, just pick another to observe.
