SIBLEY GUIDE TO BIRDS-2nd ED

The second edition (2014) is essentially an entirely new book, created by revising every element of the first edition, adding some new material, and assembling the updated parts into a new whole. Over 100 new species have been added, and over 600 new images. Most of the original paintings have been retouched in some way, and all were rescanned using the latest technology. The text is largely rewritten, maps updated, and the layout adjusted to allow more text and a more logical arrangement of text on each page.
