The Landesmuseum had promised more, Ibex and Alpine Marmot, Capercaillie and Hazel Grouse.
However, this does not cover significant parts of the habitats of 17 endangered bird species listed in Annex I of the Birds Directive, thus putting at risk the conservation of species such as Tengmalm's Boreal's owl (Aegolius funereus) and the Eurasian pygmy owl (Glaucidium passerinum), as well as the white-backed woodpecker (Dendrocopos leucotos), the three-toed woodpecker (Picoudes tridactilus), the hazel grouse (Bonasa bonasia) and the black woodpecker (Dryocopus martius).
The decline was so dramatic that a 7-year hunting ban was imposed in 1949, and the ban also included black grouse Tetrao tetrix and hazel grouse Bonasia bonasia.
Thus, Capercaillie, Black Grouse, and Hazel Grouse (Bonasa bonasius) in Finland fluctuated together with [sim]6-yr periodicity (Lindstrom et al.

Otherwise, black grouse and hazel grouse Bonasa bonasia had a significantly greater proportion of total hits in BIOSIS than in WOS, blue grouse Dendragapus obscurus and spruce grouse Dendragapus canadensis vice versa.
Hazel grouse are generally less popular and also less studied than capercaillie and black grouse.
The fluctuating Capercaillie (Tetrao urogallus), Black Grouse (Tetrao tetrix), Hazel Grouse (Bonasa bonasia), Willow Ptarmigan, Willow Tit (Parus montanus), Magpie (Pica pica), red squirrel (Sciurus vulgaris), mountain hare (Lepus timidus), and whitefish (Coreganus lavaretus) populations of the 11 provinces of Finland each showed spatial synchrony that declined with the distance between provinces (Ranta et al.
Large-scale synchrony in the dynamics of Capercaillie, Black Grouse, and Hazel Grouse populations in Finland.
The study species is the hazel grouse Bonasa bonasia, a habitat specialist with poor dispersal ability and therefore likely to be strongly affected by habitat fragmentation (Andren 1994, With & Crist 1995).
We selected the area because it is subjected to constant changes in land usage, both in terms of forest practices and anthropogenic development, all of which may fragment areas suitable for hazel grouse.
