===Breeding===
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 [[bird nest|nest]] is located on the ground near water; it is built using vegetation and lined with down. They are [[bird migration|migratory]] and winter along the eastern and western coasts of North America, on the [[Great Lakes]], coastal northern Europe and Asia, with stragglers to the [[Black Sea]]. The most important wintering area is the [[Baltic Sea]], where a total of about 4.5 million gather. As of 2022 it has also been breeding in parts of Western Europe, such as on the [[Marker Wadden]] in the Netherlands.

===Food and feeding===
The long-tailed duck is gregarious, forming large flocks in winter and during migration. They feed by diving for [[mollusk]]s, [[crustacean]]s and some small [[fish]]. Although they usually feed close to the surface, they are capable of diving to depths of {{convert|60|m|ft|abbr=on}}. According to the Audubon Society Field Guide to North American Birds they can dive to {{convert|80|fathom|m ft}}. They use their wings, like velvet scoters, to dive, which gives them the ability to dive much deeper than other ducks.
