Download or read book The North American Sea Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2016-11-09 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book AMNH Birds of NA Westn Rgn written by DK and published by Penguin. This book was released on 2011-01-17 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This definitive field guide is the only guide to use a fully integrated photographic approach to profile the extraordinary range of birds found in Western North America. The highest-quality photography brings nearly 575 species to life on the page, capturing their beauty and making identification quick and effortless. The 367 species most commonly seen west of the 100th Meridian (in the United States, the region west of the Great Plains) are featured in full-page profiles that emphasize all the information needed to identify them. Diagnostic photographs are silhouetted and clearly annotated, and any plumages, whether female, juvenile, subspecies, and winter or summer, that differ noticeably from the primary image are also included and labeled accordingly. Detailed similar species boxes show the plumage that is most similar-in some cases the female or juvenile rather than the featured adult-and the most significant differences are picked out. Stunning context photographs show the bird at home, in its normal habitat or performing behavior that is typical of that species. Schematic artworks show the shape and posture of the bird in flight as well as its coloration, and a diagram of its flight pattern is also included. The Southwest, a region characterized by its own region of birds where species common to northern Mexico may cross the border, is a popular destination because of the many species that can be seen nowhere else in eastern North America. The 80 most common of these southern gems are profiled in their own section of quarter-page entries, each with a stunning photograph annotated to point out the most significant field marks. A separate section profiles 128 species that are particularly uncommon or local in their distribution.

Book excerpt: This definitive field guide is the only guide to use a fully integrated photographic approach to profile the extraordinary range of birds found in eastern North America. The highest-quality photography brings nearly 500 species to life on the page, capturing their beauty and making identification quick and effortless. The 393 species most commonly seen east of the 100th Meridian (in the United States, the region east of the Rocky Mountains) are featured in full-page profiles that emphasize all the information needed to identify them. Diagnostic photographs are silhouetted and clearly annotated, and any plumages, whether female, juvenile, subspecies, and winter or summer, that differ noticeably from the primary image are also included and labeled accordingly.

The border of Texas and Mexico is a popular destination because of the many species that can be seen nowhere else in eastern North America. The 60 most common of these southern gems are profiled in their own section of quarter-page entries, each with a stunning photograph annotated to point out the most significant field marks. A separate section profiles 44 species that are particularly uncommon or local in their distribution.
