From Alaska to Baja California, this field guide published by the National Geographic Society, now in its fifth edition (with tabs!), is the one to carry. Practical to use in the field, it has maps, illustrations and descriptions of the birds on facing pages. The scale of the maps changes with the range of the bird, which means you get a more detailed regional map for those birds with a restricted range. This fully revised fifth edition features nearly 700 color range maps, bigger and better than ever.  (FG09, $24.00)
