In these forests, you may also see the spruce grouse and varied thrush. Plovers, gyrfalcons, mew gulls, and snow buntings are among the 159 species of birds recorded at Denali. Raven, ptarmigan, magpie, and gray jay are some of the species that winter in the park and preserve. Winter challenges wildlife with frigid temperatures and the cessation of plant growth. Food is scarce.
Grizzlies fatten up in summer and remain in a torpor or deep sleep most of the winter.
Ground squirrels and marmots hibernate, their body functions virtually halted. Beavers and red squirrels hole up and subsist on food caches. Weasels, snowshoe hares, and ptarmigan, however, turn white and continue the struggle to survive above ground against extreme conditions. Work Outdoors at GORP Jobs Click Here. All rights reserved.
