These studies covered eight grouse species across Europe and North America (Europe:
Tetrao urogallus, Lyrurus tetrix, Bonasa bonasia and Lagopus lagopus incl.
The black-billed capercaillie (
Tetrao urogalloides) is a large forest-dependent species associated with conifer-dominated forests, and considered as an important species for boreal and montane forests (He et al., 2004; Mlikovsky, 2012; Suter et al., 2002; Yin et al., 2009; Zawadzki et al., 1999).
Responses by the capercaillie
Tetrao urugallus, and the willow grouse Lagopus lagopus, to the green matter available in early spring.
Objects of protection on the territory are the following bird species: Ciconia nigra, Pernis apivorus, Milvus migrans, Circaetus gallicus, Aquila pomarina, Aquila chrysaetos, Buteo ryfinus, Falco peregrinus, Alectoris graeca, Bonasa bonasia,
Tetrao urogallus, Bubo bubo, Glaucidium passerinum, Aegolius funereus, Caprimulgus europaeus, alcedo attis, Picus canus, Dryocopus martius, Dendrocopos medius, Picoides tridactylus, Dendrocopos syriacus, Lullula arborea, Lanius collurio, Lanius minor, Sylvia nisoria, Emberiza hortulana.
The birds are represented by Aquila chrysaetos, Corvux corax,
Tetrao urogallus, and Lacerta viridis or Vipera berus are among the reptile species in the area.
The Capercaillie (
Tetrao urogallus), also known as the Wood Grouse, is the largest member of the grouse family and is renowned for its mating display.

The coal mines in question are located inside a Natura 2000 site in Laciana valley, near Villablino, Leon, which is home to several critically endangered species, including brown bear (Ursus arctos) and capercaillie (
Tetrao urogallus).

Predicting space use responses to habitat fragmentation: can voles Microtus oeconomus serve as an experimental model system (EMS) for Capercaillie grouse
Tetrao urogallus in boreal forest?
For example, Moran (1952) showed that Scottish shooting-bag records of Rock Ptarmigan (Lagopus mutus), Capercaillie (
Tetrao urogallus), and Black Grouse (
Tetrao tetrix) were correlated with those of Red Grouse (Lagopus lagopus scoticus).
The brown bear (Ursus arctos) and the capercaillie (
Tetrao urogallus) both help spread berry-bearing shrubs.
