Hardcover in very good condition in chipped dust jacket. Olin Sewall Pettingill has now extensively revamped his classic. Slightly longer and larger in format than the first edition, and featuring updated transport directions and additional pen-and-ink drawings by prominent ornithologist and bird artist George Miksch Sutton, the book remains the best guide to where and when one can find what birds. Still very useful, listing a huge number of the best birding areas.
