Book excerpt: There are forty species of hawks in North America, including vultures, the California condor, and the bald eagle, our national bird. Heintzelman's monumental study is a comprehensive survey of what we know about the migrations of these magnificent birds in North America, Central America, and the West Indies. After a general introduction on migration season, speeds, and methodology, eleven detailed chapters survey migration routes and statistics in all the following regions: eastern and western Canada, the Great Lakes area, New England, the Middle Atlantic states, southern Appalachia, the Gulf Coast, the Central states, Western states, Central America, and the West Indies. Subsequent chapters deal with the influence of weather systems and local weather variables, updrafts, thermals, altitudes and the daily rhythm of migrations, the influence of age and geography, and the role of hawk counts as indices to population trends.

Book excerpt: Until now ornithologists and bird watchers with a particular interest in hawks of North America have had to do without a useful field guide. This book satisfies that need. The most important hawk watching sites in Canada, the United States, and Mexico are now included in one volume. In addition to flight illustrations of all species, pictures of perched and nested hawks are included. The annual migrations of hawks in spring and autumn are among the most spectacular animal migrations found anywhere in the world. Many of the most important hawk lookouts are located in North America and are used regularly by thousands of bird watchers and other people interested in wildlife. Of interest to both amateur and professional bird watchers, this book provides an inexpensive, authoritative field guide to hawk watching. It includes: 1. Details of flight identification of the species seen at the lookouts, including many details not included in the various field guides to birds now available. 2. Flight illustrations of all species. 3. Explanations of the seasonal aspect of hawk migrations and the mechanics of how migrations work. 4. A discussion of essential equipment. 5. Descriptions and directions for visiting the important hawk lookouts in North America. 6. Suggestions for further reading, and a complete index. The book is handsomely designed for easy "pocket-carrying" in the field.
