Grouse (Tetraonidae)

Willow Grouse (Lagopus lagopus) - HBW 2, p. 402

French: Lagopède des saules German: Moorschneehuhn Spanish: Lagópodo Común
Other common names: Willow Ptarmigan; Red Grouse (scoticus)

Taxonomy: Tetrao lagopus Linnaeus, 1758, Swedish Lapland.
Hybrids relatively frequent with Tetrao tetrix and Bonasa bonasia; occasional with Tetrao urogallus, Falcipennis canadensis and L. mutus. Internal taxonomy confused, due to complicated plumage sequence, and based mainly on colour and pattern of summer plumages. Many races often lumped, although in quite different ways: nominate sometimes considered to include koreni, birulai, kamtschatkensis, alascensis, albus, ungavus and others, from Scandinavia to Quebec; races of SE Siberia also often merged, sserebrowsky..

Many races often lumped, although in quite different ways: nominate sometimes considered to include koreni, birulai, kamtschatkensis, alascensis, albus, ungavus and others, from Scandinavia to Quebec; races of SE Siberia also often merged, sserebrowsky in okadai and kozlowae in brevirostris. Irish birds occasionally awarded separate race, hibernicus. Nineteen subspecies currently recognized.
