Oldsquaw
Clangula hyemalis (Linnaeus)
Status Common in winter, very rare in summer. Formerly very common, its numbers have shown a marked decrease from those of a few decades ago.
The common name of this species was Oldsquaw for many years but it was changed to Long-tailed Duck in the 1990s. In the breeding season the male does indeed display a very long tail.

Long-tailed Duck (Clangula hyemalis)
(aka Oldsquaw)
The Long-tailed Duck breeds all round the Arctic in Europe, Asia and North America, wintering further south but usually at sea and, in many cases, out of sight of land.
The Long-tailed Duck, formerly known as the Oldsquaw, breeds across the Alaskan and Canadian Arctic, and spends the winter on the Pacific Ocean. Consequently, it is only a rare transient through Alberta.
