Spruce Grouse
Grouse
The Spruce Grouse, Falcipennis canadensis, is a medium-sized grouse.
Distribution
Their breeding habitat is the boreal forests or taiga across Alaska and Canada.
It also occurs in the boreal forest that extends into the United States' northern border states.
They nest on the ground in dense growth.
Description
Adults have a long square black tail. Adult males are mainly grey with a black breast with white bars, a black throat and a red patch over the eye. Adult females are mottled brown with dark and white bars on the underparts.
While the nominate species has rusty tips to the tail feathers, Franklin's Grouse (D. c. franklinii) lacks these and instead has white tips to the tail coverts.
Diet / Feeding
These birds forage on the ground or in trees in winter. The caeca, digestive sacs in the intestines, increase in size to support this bird's winter diet of conifer needles. In summer, they also eat berries, green plants, and some insects.
Behavior
The Spruce Grouse has great confidence in its camouflage, and will often stay still even when approached within a few feet (1 m). It is this characteristic that has earned them the nickname "Fool Hens". During the winter months, however, the Spruce Grouse will become very skittish due to a lack of camouflage; they take flight when approached within 20-150 feet (6-45 m). A male on territory makes a drumming sound by flapping his wings.
Less vocal than other grouse, it will make some soft calls including hoots and clucks. Males will sometimes flutter tails or wings.
Habitat
Spruce Grouse are permanent residents of coniferous forests, especially among those consisting of black spruce or jack pine. Some may move short distances by foot to a different location for winter.
Females with young may dwell at the edges of clear cuts, but tend to remain close to conifers.
Food
Spruce grouse eat many pine and spruce tree buds, as they are high in energy.
The also tend to eat pebbles, to help their gizzard digest their food.
