Natural History

Food

  • Conifer needles and buds make up about 95 percent of the blue grouse winter diet.
Reproduction and Growth

Breeding Behaviour

  • In spring, blue grouse move down to lightly wooded mountain valleys or foothills.
  • Choosing an open area, the male sets up a territory, strutting and hooting to announce his presence and attract females. Yellow-to-orange eye combs are enlarged, and tail feathers are fanned. White-based neck feathers are raised revealing bright yellow or purple skin patches.
  • After mating, the hen chooses a nest site, often at the base of a tree or under a log. She lays from 5 to 10 eggs that are buff-colored, and finely spotted with light brown.
  • Incubation takes about 25 days. When hatched, the brood leaves the nest with the hen.
  • In late summer, large family groups disperse and individual or small groups of birds then make their way up to the forests of their winter range.
