DOWNLOAD EBOOKContains information on the locations, methods, and timing of the collections of samples of prey of resident waterfowl from the littoral zones of 62 lakes and wetlands in the Algoma, Muskoka, and Sudbury regions of Ontario. The specimens are being collected as part of the Food Chain Monitoring Program (FCMP) of the Long Range Transport of Air Pollutants (LRTAP) Biomonitoring Program. The prey sampled includes macroinvertebrates, fish, and amphibians, many of which are acid-sensitive and absent from lakes degraded by acid precipitation. The FCMP will detect changes in the composition and abundance of major prey as damaged aquatic ecosystems recover from the effects of acid precipitation as a result of emission abatement programs. The report also summarises the invertebrate, fish, and amphibian taxa collected 1987-94, along with the locations of the collections, taxonomic keys used for identification, and minimum pH at which the specimens were caught.

DOWNLOAD EBOOKThe 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.

Honorable Mention for the PROSE Award for Excellence, Multivolume/Science of the Association of American Publishers Ducks, Geese, and Swans of North America has been hailed as a classic since the first edition was published in 1942. A must-have for professional biologists, birders, waterfowl hunters, decoy collectors, and wildlife managers, this fully revised and updated edition provides definitive information on the continent's forty-six species. Maps of both winter and breeding ranges are presented with stunning images by top waterfowl photographers and the acclaimed original artwork of Robert W. (Bob) Hines. Originally authored by F. H. Kortright and later revised by Frank Bellrose, this latest edition, which has been meticulously updated by renowned waterfowl biologist Guy Baldassarre, continues the legacy of esteemed authors. Each species account contains in-depth sections on: • identification • distribution • migration behavior • habitat • population status • breeding biology • rearing of young • recruitment and survival • food habits and feeding ecology • molts and plumages • conservation and management To facilitate identification, the species accounts also include detailed illustrations of wings. An appendix contains comparative illustrations of ducklings, goslings, and cygnets.

DOWNLOAD EBOOKNunavut is a land of islands, encompassing some of the most remote places on Earth. It is also home to some of the world’s most fascinating bird species. The windswept tundra, rocky shorelines, and icy waters of this thinly populated land are integral to the survival of numerous breeding and non-breeding birds, including the colourful King Eider, the stately Snowy Owl, the spritely Snow Bunting, and the globe-spanning Northern Wheatear. Birds of Nunavut is the first complete survey of every species known to occur in the territory. It is co-written by a team of eighteen experts who have conducted a combined total of 300 seasons of fieldwork in Nunavut. They document 295 species of birds (of which 145 are known to breed in the territory), presenting a wealth of information on identification, distribution, ecology, behaviour, and conservation. Lavishly illustrated with over 800 colour photographs and 155 maps, it is a visually stunning reference work on the birds that live in and visit Nunavut.
