    The familiar Gray Catbird proved to be ubiquitous during the Atlas Project with representation in every priority block. Breeding Bird Surveys indicate they are most numerous in the Glaciated Plateau, Unglaciated Plateau, and Illinoian Till Plain regions in southern and eastern Ohio where brushy edge and successional habitats are widely distributed.   Speaking of birds, Kathy Harp mentioned one of my favorite of all times in her recent blog, and I was transported back to a lookout at the top of a small mountain in Pine Grove Furnace State Park in Pennsylvania, home of a large old growth forest which I believe could be included in the ZONE. It was nearly 50 years ago and I watched this large bird in his bobbing .

    Migration - Migration - Birds: Migration is most evident among birds. Most species, because of their high metabolic rate, require a rich, abundant supply of food at frequent intervals. Such a situation does not always prevail throughout the year in any given region. Birds have thus evolved a highly efficient means for travelling swiftly over long distances with great economy of energy.   The Crossley ID Guide: Eastern Birds is undoubtedly the most innovative avian reference guide to come along in many years. In fact, the guide represents such a bold leap forward that reading it makes one wonder what the future of bird guides holds. This is why we asked readers to share their views on the NEXT big step in bird guide design, philosophy, or .

This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration. It deals with all aspects of this absorbing subject, including the problems of navigation and vagrancy, the timing and physiological control of migration, the factors that limit their populations, and by:   I didn't finish the book, specifically the chapters on the tropical/wintering grounds of migratory birds, but was very impressed with the tone of the book.

It was very clear for lay readers, and the author's ability to convey the complexity of bird ecology, as it relates to declining numbers of certain migratory birds, was laudable/5. The book is divided into nine chapters and five ap­ pendices.

The Introduction, or first chapter, defines the scope of the book as a "summary of information and ideas on the biology and conservation of migra­ tory birds, mainly from a Neotropical perspective." A Neotropical perspective was deemed necessaryAuthor: Deborah M.

Breeding in open or semi-open country across most of North America, this bird is a brood parasite: it lays its eggs in the nests of other small perching birds, particularly those that build cup-like nests, such as the Yellow Warbler. The young cowbird is fed by the host parents at the expense of their own young.

Stopover Habitats and What Birds Need on Migration By Ken Rosenberg, Nick Bayly, and Camila Gómez Ap Migration is possibly the riskiest activity many birds undertake in their lives, and yet billions of birds representing nearly species migrate between North America and tropical regions to the south every spring and fall.

Scientists have long noticed that birds feed intensely as air pressure falls. They apparently have an inborn barometer that is extraordinarily sensitive. This is a handy adaptation for all birds, even non-migrants, because storms usually are associated with falling pressure, and birds have a hard time getting food during a storm.

WL is not a parameter used in estimates of energy requirements for flight - heavy birds just fly faster and fast birds can carry any weight that is adaptive Ie.g. huge eggs).
