Documents and reviews much of what is known about the biology and natural history of this bird.
Part 1 is principally introductory, describing approaches and introducing the principal studies and study areas on which the book is based. Part 2 provides a background to the bird, e.g. its taxonomy, evolution, and the environment in which it lives. Physical attributes, e.g. its morphology, reproduction, and food habits are examined in Part 3. Part 4 is devoted to individual and collective behaviours. Finally, Part 5 documents the principal population parameters of this grouse and identifies some of what is known about its predators and diseases, agents potentially important to prey populations.
