Book Summary

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.
