Query: The Sibley Field Guide to Birds of Western North America

If you have a bird feeder near your house and maybe a bird bath, too, you're more than casually interested in birds and this book is for you. I use it to satisfy my curiosity by identifying the unusual birds that occasionally show up in my urban back yard, such as the small hawk that hunts all those little brown birds around my bird feeder. I also take it along on drives through the countryside, along with a good pair of binoculars. Seeing an interesting bird can be a good excuse to stop driving for a bit and look at something more interesting than other cars on a highway.
