Book Description
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.

Book Description
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.

Book Description
The captivating, little-known true story of a group of scientists and the methods and technology they developed to uncover the secrets of avian migration. For the past century, scientists and naturalists have been steadily unravelling the secrets of bird migration. How and why birds navigate the skies, traveling from continent to continent—flying thousands of miles across the earth each fall and spring—has continually fascinated the human imagination, but only recently have we been able to fully understand these amazing journeys. Although we know much more than ever before, even the most enthusiastic birdwatcher may not know how we got here, the ways that the full breadth of scientific disciplines have come together to reveal these annual avian travels. Flight Paths is the never-before-told story of how a group of migration-obsessed scientists in the twentieth and twenty-first centuries engaged nearly every branch of science to understand bird migration—from where and when they take off to their flight paths and behaviors, their destinations and the challenges they encounter getting there. Uniting curious minds from across generations, continents, and disciplines, bird enthusiast and science writer Rebecca Heisman traces the development of each technique used for tracking migratory birds, from the first attempts to mark individual birds to the cutting-edge technology that lets ornithologists trace where a bird has been, based on unique DNA markers. Along the way, she touches on the biggest technological breakthroughs of modern science and reveals the almost-forgotten stories of the scientists who harnessed these inventions in service of furthering our understanding of nature (and their personal obsession with birds). The compelling and fascinating story of how scientists solved the great mystery of bird migration, Flight Paths is an unprecedented look into exciting, behind-the-scenes moments of groundbreaking discovery. Heisman demonstrates that the real power of science happens when people work together, focusing their minds and knowledge on a common goal. While the world looks to tackle massive challenges involving conservation and climate, the story of migration research offers a beacon of hope that we can find solutions to difficult and complex problems.

Book Description
An illustrated guidebook that describes forty-nine natural places in Pennsylvania to explore and enjoy. In this sequel to the popular guidebook Outbound Journeys in Pennsylvania, Marcia Bonta describes forty-nine new outstanding natural places in Pennsylvania, featuring their old-growth forests, scenic rivers, spectacular waterfalls, rare botanical localities, outstanding wetlands, unique geological formations, endangered ecosystems, and special birdwatching areas. The book is divided into three sections--Eastern, Central, and Western Pennsylvania--and covers unique natural features in state parks, state forests, private nature sanctuaries, state game lands, county parks, environmental education centers, and a National Military Park. Each chapter discusses the flora and fauna of the site, as well as its unique features and also contains historical information so that people can learn about Pennsylvania's natural heritage without necessarily visiting the places. Bonta gives precise directions on how to reach each area, most of which are easily accessible from the major population centers of the state. In addition, she offers complete information on each site, including the best trails to follow, telephone numbers, hours, availability of group tours, and admission charges. A special section on sources and the detailed bibliography give readers more information on how to obtain maps and books that will add to their appreciation and knowledge of the places and natural history covered in the book. Most of the outings are not too strenuous and are ideal for families and groups of all kinds and ages. Aimed at a broad audience of naturalists, both armchair and active, More Outbound Journeys in Pennsylvania will also interest birdwatchers, hikers, campers, fishermen, hunters, canoeists, and wildflower and plant enthusiasts. Anyone who is interested in outdoor Pennsylvania can use this book to discover and enjoy the natural beauty of the Keystone State.
