You’ll notice that I’m reviewing bird books. (Don’t worry, not all will be US based.) Please feel free to chime in with your suggestions and comments.
The ultimate bird book for North America has always been two books: both Peterson’s field guides, one for the East, one for the West. Now, the new Peterson Field Guide to Birds of North America (Peterson Field Guide Series) combines the two. I do not own a copy, and therefore can not review it for you. (Note: I don’t normally review books that publishers are unwilling to send me, and Houghton Mifflin has not been a good partner lately.)
Anyway, even though I find myself not liking the publisher too much, the book is a standard and you need to have one.
