Book Description
The western Canada goose (Branta canadensis moffitti) was divided into a Rocky Mountain population (RMP) and a Pacific population (PP) on the basis of band recovery programs examined in this study and recovery data from other investigators. Habitat information provided a base line for evaluating future changes in nesting, molting, and wintering areas. Topics covered in the discussion of breeding biology are nesting chronology, spring population composition, breeding age, clutch size, nesting success, artificial nesting structures, and gosling survival. Some management recommendations include the refinement and standardization of spring and winter aerial surveys, and more accurate age and sex determinations when geese are banded and color-marked.

Book Description
The eight currently recognized species of North American geese are part of a familiar group of birds collectively called waterfowl, all of which are smaller than swans and generally larger than ducks. They include the most popular of our aquatic gamebirds, with several million shot each year by sport hunters. Our two most abundant waterfowl, the Canada goose and snow goose, have populations collectively totaling about 15 million individuals. Like swans, the lifelong pairbonding of geese, their familial care, and prolonged social attachment to their offspring are legendary. Their seasonal migratory flights sometimes span thousands of miles, and the sight of their long, wavering flight formations are as much the symbols of seasonal change as are the spring songs of cardinals or the appearance of autumnal leaf colors. This book describes each species' geographic range and subspecies, its identification traits, weights and measurements, and criteria for its age and sex determination. Ecological and behavioral information includes each species' breeding and wintering habitats, its foods and foraging behavior, its local and long distance movements, and its relationships with other species. Reproductive information includes each species' age of maturity, pair-bond pattern, pair-forming behaviors, usual clutch sizes and incubation periods, brooding behavior, and postbreeding behavior. Mortality sources and rates of egg, young, and adult losses are also summarized, and each species' past and current North American populations are estimated. In addition to a text of nearly 60,000 words, the book includes 8 maps, 21 line drawings, and 28 photographs by the author, as well as more than 700 literature citations.

Book Description
The #1 selling wildlife management book for 40 years, now updated for the next generation of professionals and students. Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this eighth edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy and published in association with The Wildlife Society, the 50 authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a 2-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on pragmatic management methodologies. Volume 1 describes research design and proper analytic methods prior to conducting research, as well as methods and considerations for capturing and handling wild animals and information on identification and marking of captured animals. It also includes new chapters on nutritional research and field sign identification, and on emerging topics, including structured decision-making. Finally, Volume 1 addresses measurements of wildlife abundance and habitat and research on individual animals. Volume 2 begins with a section on the relationship between research and management including public outreach, described in a context that encourages engagement prior to initiation of management. An adaptive management approach is described as a cornerstone of natural resource management, followed by a section on managing landscapes and wildlife populations. The volume also includes new chapters on ethics in wildlife science and conservation, conflict resolution and management, and land reclamation. A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.
