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:
âCaptioned illustrations show many previously unpublished field marks and revisions of known marks
âNearly every species is shown in flight
âMeasurements include length, wingspan, and weight for every species
âSubspecies and geographic varients are covered thoroughly
âComplete voice descriptions are included for every species
âMaps 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:
âAn introductory page for each family or group of related families makes comparisons simple
âClear and concise labels with pointers identify field marks directly
âBirds are illustrated in similar poses to make comparisons between species quick and easy
âIllustrations 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.
