David Allen Sibley, America's most gifted contemporary painter of birds, is the author and illustrator of this comprehensive guide. His beautifully detailed illustrations—more than 6,600 in all—and descriptions of 810 species and 350 regional populations will enrich every birder's experience.

The Sibley Guide 's innovative design makes it entirely user friendly. The illustrations are arranged to facilitate comparison, yet still capture the unique character of each species.

The Sibley Guide to Birds provides a wealth of new information:

—Captioned illustrations show many previously unpublished field marks and revisions of known marks

—Nearly every species is shown in flight

—Measurements include length, wingspan, and weight for every species

—Subspecies and geographic varients are covered thoroughly

—Complete voice descriptions are included for every species

—Maps show the complete distribution of every species: summer and winter ranges, migration routes, and rare occurrences

Both novice and experienced birders will appreciate these and other innovative features:

—An introductory page for each family or group of related families makes comparisons simple

—Clear and concise labels with pointers identify field marks directly

—Birds are illustrated in similar poses to make comparisons between species quick and easy

—Illustrations emphasize the way birds look in the field

With The Sibley Guide to Birds , the National Audubon Society makes the art and expertise of David Sibley available to the world in a comprehensive, handsome, easy-to-use volume that will be the indispensable identification guide every birder must own.

耗時十餘載，大衛·希波利這本鳥類圖鑒堪稱裏程碑之作。美輪美奐的水彩畫插圖（6600幅，涵蓋810個北美鳥類物種）加上簡明扼要的說明體現瞭該書的創作繼承瞭鳥類圖鑒畫大師約翰·詹姆斯·奧杜邦（John James Audubon）和羅傑·托裏·彼得森（Roger Tory Peterson）的風格。

希波利不僅僅是一名鳥類觀察傢和鳥類知識傳播者，他更是美國舉足輕重的鳥類畫傢和鳥類權威。毫無疑問，他的鳥類野外圖鑒定會激起強烈反響。與肯•考夫曼的照片圖鑒不同，希波利的圖片完全靠手繪。鳥類觀察的初學者或許會將希波利的圖鑒放在傢裏作參考，但該書豐富的信息量足以讓初學者在數韆隻鳥組成的鳥群中辨認齣一隻磯鷸。這種為人熟知的鳥在這本圖鑒裏有九張獨立的插圖，記錄瞭其地理、季節和性彆變體，另外還有八張錶現其飛行的小插圖。配閤希波利對彼得森和國傢地理圖鑒的改進，這種錶現細緻的圖鑒定會讓有經驗的鳥類觀察者愛不釋手。
