About Falcipennis
The Siberian grouse (Falcipennis falcipennis), also known as Siberian spruce grouse, Amur grouse, or Asian spruce grouse, is a short, rotund forest-dwelling grouse. A sedentary, non-migratory bird, it is the only member of the genus Falcipennis. The spruce grouse of North America, which physically looks similar, is now placed in the monotypic genus Canachites.
