This second edition of the only reference devoted to diseases of wild waterfowl has been completely revised to include several new viral agents and toxins. The entire text reflects an increased emphasis on the relationships among habitat, management, and the occurrence of disease. Chapter format is consistent throughout, with the cause ecology, clinical and pathologic features, diagnostic techniques, significance, and remedial management of each disease described. Among the highlights are a chapter on diagnostic techniques (which includes the necropsy procedure) and an extensive reference list.
