A very nice field guide, I got it for my little boy and I to look up the various birds we see around our area. It is very easy to use with a silhouette guide and tons of really great artist's plates of the birds. The Peterson Field Guides Birds of Eastern and Central North America also has four-hundred and fifty map plates showing the most likely occurrence's of all the birds in the area, it is a very in-depth study of wildlife for our part of the United States. The Peterson Field Guides Birds of Eastern and Central North America has become a routine item to take an any trip we go on now to make sure we don't miss anything. It is a semi-hardcover book it's construction is such that it must have been intended to be carried around a lot, ours has taken lots of abuse and is still going strong with the exception of a little curling around the edges. I would recommend this field guide to anyone interested in learning more about the birds of this area. I really wish I had something like this when I was a child maybe I would not have been so surprised at how many different types of birds we really do have around our little neck of the woods.
