Complete Birds of North America - Field Guide Book for Bird Watching, Identification & Photography | Perfect for Outdoor Enthusiasts, Nature Lovers & Ornithologists

It weighs a little over 4 lbs. is 7 1/4 inches wide, 10 inches high and 1 and 7/8 inches thick. Wont fit in your pocket. Probably the most complete bird book for this area. I have a book called, "Smithsonian Birds of North America, Life histories of more than 930 species, Fred J. Alsop III. I thought that book was good but this book is far and away better. The Smithsonian book was missing the American Goldfinch and the Swan Goose, native of Eastern Asia, domestic Chinese Goose and African Goose. I spotted one at Silver Lake in Bristol, PA. I showed a picture I had taken of the goose at my bird club meeting and two members thought it was a crossbreed. I had not gotten my National Geographic book yet. When it came I found it. Looking for a book I could carry in my cargo pants leg pocket I bought, "Peterson Field Guide to Birds of Eastern and Central North America. It's also to big to put in the leg pocket but you could pack it along. I'm not too thrilled with The Peterson book. It has a little over 40 pages in the back showing the ranges of the birds and yet their is a small map for each bird on the page where the bird is displayed which works just as well, however, it should do well to carry in my car or in a fanny pack. I have an Olympus SP820U camera with a 40x wide angle and telephoto lens, witch is great for taking pictures of birds maybe 30 yards away and using National Geographic book to identify. I then record everything in my' Rite in the Rain, all weather Birder's Journal. That works. I read some ratings that complain about how poorly the National Geographic book is bound. One said the pages come loose. I've just received my book so I can't comment on longevity but the binding seams normal to me. A hardcover book can be abused if you don't handle it properly like forcing it open. I don't think ill have a problem.
