The Long-Tailed Duck is a noticable duck because of its beautiful colours and long tail. Global warming is probably a threat to its existence.  It is on the IUCN Red List of Threatened Species, with the status vulnerable. In the wintertime it stays in the ocean around Iceland but in the summer it is a breeding bird in the interior where the climate  is colder, more arctic.

This picture is taken in Veiðivötn, Fishing Lakes, in the interior of Iceland. The male bird is at the front, the female behind.
