There are eight currently recognized species of North American geese: emperor, greater white-fronted, snow, Ross's, Canada and cackling, barnacle, and brant geese. This book describes each... More > 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 summarized, and the past and current populations of all species are estimated. The book includes 8 maps, 21 line drawings, 28 photographs by the author, and more than 700 literature citations.< Less
The North American Grouse: Their Biology and Behavior By Paul Johnsgard

This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of... More > which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating “leks,” arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. The book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.< Less

Among the... More > largest of all flying birds, they have been used as symbols of royalty, grace and beauty, and largely for these reasons swans have only rarely been considered acceptable as targets for sport hunting. Swans occur on all continents but Africa, though most species are found in the temperate and arctic zones of North America and Eurasia. Swans are a long-lived species and are among the most strongly monogamous of birds, having prolonged pair and family bonds that influence their flocking and social behavior, and contribute to the overall high degree of human interest in them. This volume describes their distributions, ecology, social behavior, and breeding biology. Included are nine distribution maps, 19 drawings, 23 photographs by the author, and a bibliography of nearly 700 references.< Less
