Many raptors, the hawks, eagles, and falcons of the world, migrate over long distances, often in impressively large numbers. Many avoid crossing wide expanses of water and follow "flyways" to optimize soaring potential. Atmospheric conditions and landscape features, including waterways and mountain ranges, funnel these birds into predictable bottlenecks through which thousands of daytime birds of prey may pass in a short time. Birders and ornithologists also congregate at these locations to observe the river of raptors passing overhead (as did hunters in the United States in the past and...

Birds have long held a unique dual role as a model group for scientists and as the focus of birders' passionate quests. Despite centuries of observation, each year brings the discovery and description of several entirely new avian species and hundreds of other taxonomic "splits" or "lumps" based on DNA data. In this arena of continual and increasing taxonomic change, The Clements Checklist presents the most up-to-date and most widely endorsed compendium of the more than 9800 species of birds recognized by the scientific and birding communities.

The Birds of Ecuador comprehensively treats the nearly 1600 species of birds that can be found in mainland Ecuador in two volumes.

Birds are, happily, numerous in many parts of Ecuador: even the downtown parks of the big cities such as Quito and Guayaquil host their complement."

Volume I, Status, Distribution, and Taxonomy, contains detailed information on the ecology, status, and distribution of...

"Improving the quality of land for wildlife is the single most constructive step that anyone can take to assist wild bird populations. Happily, it is well within almost everyone's capability to improve bird habitats by providing important food and cover plants. Through this book, I will assist caring landowners and managers of properties ranging in size from urban balconies and suburban backyards to larger properties such as country estates, schoolyards, cemeteries, corporate parks, airports, golf courses, wildlife refuges, and parklands of all sizes. Managers of agricultural land,...

In Discovering Birds, Paul Lawrence Farber rejects the view that eighteenth-century natural history disappeared with the rise of nineteenth-century biology. In this penetrating case study of the history of ornithology, Farber demonstrates interesting continuities: as natural history evolved into individual sciences (botany, geology, and zoology) and specialties (entomology and ichthyology), the study of birds emerged as a distinct scientific discipline that remained observational and taxonomic. Ornithologists continued to see one of their primary tasks as classification, and they...

There is no group of birds more mysterious and fascinating than owls. The loudmouths of the raptor world, they peep, trill, toot, bark, growl, shriek, whistle, chittle, whoop, chuckle, boom, and buzz. Indeed, very few actually -hoot.- They have become the stuff of lore and legend--from the Roman myth that an owl foot could reveal secrets to the First Nations belief that an owl feather could give a newborn better night vision. But the truth about owls is much more exciting.

In this gorgeous book, celebrated natural history writer and wildlife photographer Wayne Lynch reveals the...

As a boy growing up in North Dakota, Paul A. Johnsgard measured his winters not by conventional time units, but in the days it took for the snow geese to return from their wintering grounds to Lake Traverse. In this book he recounts the story of one year in the life of a pair of...
