From Eared Grebes, Tundra Swans, and Peregrine Falcons to Lesser Yellowlegs, and Snowy Owls, Pennsylvania is home to a magnificent array of birds. In the first comprehensive summary and analysis in over a century of the birds of that state, Gerald M. McWilliams and Daniel W. Brauning provide a wealth of information for both the professional ornithologist and the amateur birder. This book treats all 428 species seen in the state, including breeding and wintering birds, migrants, and vagrants. Each entry provides the general status of a species; the locations where it is most commonly found; its natural habitat, migratory patterns, breeding habits, and seasonal status and distribution; and a summary of the bird's history in Pennsylvania. With clear descriptions of physiographic regions as well as 44 breeding distribution maps for the most commonly seen birds and 67 photographs of many rare and hard-to-find species, this volume is an indispensable resource about Pennsylvania's bird life.

Reaching from interior Alaska across Canada to Labrador and Newfoundland, North America’s boreal forest is the largest wilderness area left on the planet. It is critical habitat for billions of birds; more than 300 species regularly breed there. After the breeding season, many boreal birds migrate to seasonal habitats across the United States, Mexico, the Caribbean, and Central and South America. This volume brings together new research on boreal bird biology and conservation. It highlights the importance of the region to the global avifauna and to the connectivity between the boreal forest and ecoregions throughout the Americas. The contributions showcase a unique set of perspectives on the migration, wintering ecology, and conservation of bird communities that are tied to the boreal forest in ways that may not have been previously considered.

Avian Biology, Volume VI is a compendium of papers that deals with selected aspects of avian biology. One paper discusses the avian mating behavior and covers topics such as monogamy, polygyny, male incubation, and female emancipation; these papers also list a table of the species of birds in which polyandry has been observed. Another paper examines bird migration in relation to the mechanism and development of migration with emphasis on the evolution and function (ultimate causation) of migration. Another paper discusses the advantages of one form of social organization of birds during the non-reproductive season over another form. This paper reasons the possibility of the existence of a cost-benefit social behavior. Other papers discuss some physical features found in birds such as stomach oils and glycogen-filled cells. Another paper deals with the respiratory physiology of birds as new research data have been made available in this area. This book can prove useful for investigators in avian biology, zoologists, and readers who have a general interest in birds.
