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- Captioned illustrations show many previously unpublished field marks and revisions of known marks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