Sibley's beautiful field guide to North American birds is now fully revised and updated. What's new in this edition? There are 111 new species and 626 new images. Sibley has substantially rewritten the text, changed more than half of the paintings, and updated the maps. All 7000 images have been digitally photographed to create an exacting match to the original paintings. A great addition to any birder's bookshelf. The second printing is now in stock.
