I'm from europe and do birdwatching in europe. I got this for my trip to Florida, and had a lot of use for it, as I stayed in an area with a lot of swamps and forests, and lots of wading birds. The book made it fast and easy to identify american birds, it points out characteristic details in flight and behavior, not only color and pattern, that might not always be visible. Sound descriptions are good and accurate. It is everything you'd expect from a modern bird book.
In addition, it is a thing of beauty, the illustrations are not only very informative, but also very beautiful. The text is also very interesting, even when not out in the field.
Get it, wether you live in eastern Northern America, or is just visiting!
