The only species in the genus Histrionicus, but fairly closely related to Long-tailed Duck and the scoters.

[edit] Subspecies

Two subspecies are accepted by some authors[1], though others consider the species monotypic[2][3][4].

  • H. h. histrionicus:
  • H. h. pacificus:

Some eastern European vagrants are thought to come from the Pacific population, rather than the more sedentary Atlantic population[4].

[edit] Habitat

Breeds beside cold, fast-flowing rivers; winters at sea off exposed rocky shores.

[edit] Behaviour

[edit] Breeding

The nest is usually located in a well-concealed location on the ground near a stream.

[edit] Diet

Their diet consists mostly of molluscs and other crustaceans with the addition of insects and their larvae in the spring and summer months.
