The Goldeneye is found across the northern hemisphere in temperate and arctic zones.
It is normally migratory but there are small resident populations in north west Europe.

They nest in hollows in trees and this tends to be a limitation to numbers. There has been a small breeding population in
Scotland since 1970 and this has been encouraged by erecting nesting boxes in suitable habitat.
In Britain there are about 100 breeding pairs. It is a Schedule 1 bird and so should not be disturbed while nesting.

They are in breeding plumage and form their pair bonds before returning to their breeding grounds between February and April.
Their food consists of shellfish and insect larvae which they catch by diving to depths of up to 4 metres.

The Long-tailed Duck or Oldsquaw, Clangula hyemalis, No: Havelle

The Long-tailed Duck or Oldsquaw, Clangula hyemalis, is a medium-sized sea duck. It is the only living member of its genus, Clangula; this was formerly used for the goldeneyes, with the Long-tailed Duck being placed in Harelda.

Adults have white underparts, though the rest of the plumage goes through a complex moulting process.
The male has a long pointed tail (10 to 15 cm) and a dark grey bill crossed by a pink band. In winter, the male has a dark
cheek patch on a mainly white head and neck, a dark breast and mostly white body. In summer, the male is dark on the head,
neck and back with a white cheek patch.

Their breeding habitat is in tundra pools and marshes, but also along sea coasts and in large mountain lakes in the North Atlantic region, Alaska, northern Canada, northern Europe and Russia. The nest is located on the ground near water;

The Long-tailed Duck breeds often in or near Arctic Tern colonies, and benefit of the terns defenceabilities for the Arctic fox,
Gulls and Skuas.
