Male Dusky Grouse in Ruby Mts. |
General
Description: Dusky Grouse (Dendragapus obscurus)
are mottled brown, chicken-like birds with a dark tail. Males have a
yellow comb above the eye that can be
raised during displays, and black-tipped white feathers on the neck
that cover reddish patches of bare skin, which are inflatable during
displays. Females are mottled brown above and mottled gray below.
Northern populations of Dusky Grouse (Nevada-Idaho border north) lack
the blue-gray tail band seen in Sooty Grouse, butDusky Grouse in the southern part of the species range (Nevada, Utah, southward) do have the tail band.
Favored Habitat: Mountainous areas with conifer trees. |
