Book Description
"Birds of Washington is the first complete reference work on Washington's birds to be published in more than fifty years. Designed to enrich the popular study of Washington birds, this comprehensive volume includes individual accounts of the 483 species recorded in the state." "Birds of Washington is not a field guide for identifying birds. Instead, it compiles and presents in a single volume current information about the population status and distribution of each species, as well as their habitat preferences, their seasonal activities, apparent trends and changes in occurrence or abundance, the occurrence of subspecies, and any management or conservation issues. Seasonal distribution maps are included for many selected species. More than forty contributing authors volunteered their time and expertise to create these authoritative accounts, which draw on a wide range of sources, including scientific journals, wildlife agency reports, field observations, and surveys such as Christmas Bird Counts and Breeding Bird Surveys." "While establishing a benchmark for future studies, Birds of Washington provides an indispensable source of information on avian life in the state for a broad audience of birders, wildlife biologists, land managers, conservationists, hunters, and wildlife enthusiasts in general."--BOOK JACKET.

Book Description
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

Book Description
The 21 species of sea ducks are one of the larger subgroups (Tribe Mergini) of the waterfowl family Anatidae, and the 16 species (one historically extinct) that are native to North America represent the largest number to be found on any continent, and also the largest number of endemic sea duck species native to any continent. Although generally not important as game birds, the sea ducks include some economically important birds such as the eiders, the basis for the Arctic eiderdown industry and a historically important food source for some Native American cultures. They also include what is probably the most northerly breeding species of all waterfowl and an icon of Arctic bird life, the long-tailed duck. The sea ducks also include species having some of the most complex and diverse pair-forming postural and acoustic displays of all waterfowl (goldeneyes and bufflehead), and some of the deepest diving species of all waterfowl (scoters and long-tailed duck). Sea ducks are highly prone to population disasters caused by oil spills and other water contaminants and, like other seabirds, are among the first bird groups that are being affected by current global warming trends in polar regions. This book is an effort to summarize succinctly our current knowledge of sea duck biology and to provide a convenient survey of the vast technical literature on the group, with over 900 literature references. It also includes 90,000 words of text (more than 40 percent of which is new), 15 updated range maps, 11 black & white and 20 color photographs, over 30 ink drawings, and nearly 150 sketches. Lastly, the North American sea ducks include the now extinct Labrador duck, the only northern hemisphere waterfowl species to have gone extinct in modern times. I have gratefully reprinted a Labrador duck watercolor by Sir Peter Scott. Considering recent population crashes in other sea ducks, such as the Steller’s eider and spectacled eider, it should also offer a sobering reminder of the fragility of our natural world and its inhabitants, including us.
