Are you ready to take your birding to the next level? Then spend some time getting to know your LBJ's (little brown jobbers) by investing in the book Sparrows of the United States and Canada: A Photographic Guide.
No field guide less than a foot thick could ever show all the possible variations of birds, but for sparrows, this book comes awfully close.
I have been using it recently to learn the subspecies of Dark-eyed Juncos and White-crowned Sparrows. A recent sighting of a White-throated Sparrow in the Boise area sent me running to this book to learn all about them.
The layout of the book is fantastic and the photography is excellent. My compliments to compilers David Beadle and James Rising. This is a must have reference book for every serious birder.
Price: As low as $18 online.
