Habitat Selection by Spruce Grouse in Northern Michigan

TL;DR: The population structure of the spruce grouse was studied in the Adirondack Mountains of New York, U.S.A. using the MacArthur-Wilson survivorship model, which closely predicted the proportion of occupied patches for an average population density.

TL;DR: It is shown that there is a reasonable coincidence between the Canada lynx cycle and the occurrence of forest and brush fires, and it is concluded that Grange's (1949, 1965) hypothesis that fire and plant succession drive the snowshoe hare cycle deserves serious consideration.

TL;DR: Habitat composition of 39 capercaillie Tetrao urogallus display grounds was compared with available and unused habitats in two coniferous forest areas in southeastern Norway, and a pronounced macro-habitat preference was found for elevated areas with forests older than 60-70 years.

TL;DR: In this article, the authors reported that spruce and ruffed grouse varied considerably in patterns of habitat use during periods of snow cover and showed increased use of upland conifers.

TL;DR: Foods in 37 crops of spruce grouse collected after snowfall in the Chapleau and White River Forestry Districts of Ontario, 1957-59 are analyzed.
