  hazel
Hazel grouse are found in a wide variety of habitat types that provide this structural requirement; old growth as well as managed deciduous or coniferous forests of different harvest regimes and successional stages.
In Japan, sport hunting of hazel grouse is popular, but shooting bags have dropped from 50,000 in the late 1960s to 5,000 in 1991, because of a population decline.
A dramatic decline in hazel grouse numbers in Japan coincided with an increase in red foxes; in parts of Europe, increasing numbers of generalist predators and wild boar are believed to result in reduced survival and nesting success.

 Hazel Grouse - Wikipedia, the free encyclopedia
The Hazel Grouse or Hazel Hen (Bonasa bonasia) is a large bird in the grouse family.
The plumage of this plump bird is finely patterned, but Hazel Grouse essentially has grey upperparts, brown wings and chestnut flecked white underparts.
The calls, or the burr of the flying birds' wings, are often the only indication of this grouse's presence, since its shyness and dense woodland habitat make it difficult to see.

The Hazel Grouse was probably to be found in all types of copse when these were regularly exploited, and shortly afterwards.
Thus Hazel Grouse numbers have fallen, on the one hand, because the soil is too poor for hazel, and on the other, because on the richer soils of the hornbeam oakwoods, the hornbeam has formed a dense cover.
The fewer and degrated copses inhabited by the Hazel Grouse are, to all extents and purposes, the result of the industrial revolution, when wood ceased to be a prime source of energy and fertilizer.

In winter, fl grouse feed on shrubs such as Vaccinium, Calluna, and Juniperus and, if these are snow-covered, they rely on catkins, buds, twigs, and needles of various tree species, especially birch, alder, and willow, but also spruce and pine.
Drainage and destruction of moorland, fertilisation or afforestation of heathland and sheep pastures, and the declining use and maintenance of alpine summer pastures by grazing and mowing are common causes of the deterioration of fl grouse habitats.
Locally, however, reserves are seen as vital for fl grouse conservation: In Belgium, the Netherlands, and northern Germany, most remaining populations are in nature reserves (or military training grounds, which have similar effects), which are considered to be critical for their survival.

 DYNAMICS OF GROUSE POPULATION IN TRENTINO   (Site not responding. Last check: 2007-10-30)
Hazel grouse (Bonasa bonasia) inhabit the lower and medium altitude woodland (700-1200 m average range) and are associated with a mosaic of deciduous trees and conifers in different aged stands.

For fl grouse and hazel grouse detrended series, a significant negative relationship was observed in synchrony with distance (bootstrapped cross-correlation vs distance between pair of populations r = -0.20, n = 153, P < 0.05; r = -0.39, n = 120, P < 0.001, respectively).

The southern limit of the species mostly parallels the southern border of the boreal forest; in central Europe the hazel grouse also occurs in deciduous temperate forests and montane forests south of the boreal zone.
Habitat loss, fragmentation, and degradation related to changes in human land use or silvicultural practices are the most important threats to the hazel grouse.
A loss of a dense understorey in industrial forests (central, southern Europe; Fennoscandia), and clearcutting (boreal forest) may result in declining hazel grouse numbers.
