The grouse and ptarmigans comprise sixteen species distributed throughout much of the Northern Hemisphere. This book covers the entire world assemblage of these birds.
The first part of the text addresses comparative ecology, comparative behavior, and evolution, as well as problems of applied biology such as game management, conservation, and aviculture. Johnsgard discusses general physical and physiological characteristics of the group, including the sequence of molts and plumages; reproductive biology, including hybridization; population ecology and dynamics; and social behavior and vocalizations.
The second part provides individual species accounts that cover such subjects as vernacular names; subspecies; distribution and range; weights and measurements; field identification by species, age, and sex; habitats and foods; and ecology, biology, and reproductive behavior.
Distribution maps are provided for each species, as well as drawings or diagrams illustrating family groups, morphological or behavioral traits, and biological data, and the book contains seventy-nine black & white photographs and fifty-one color plates.
413 pp. B & W illustrations and maps. Color and B & W photos.
