Much more than a field guide, this essential reference includes detailed descriptions of all the world's seabirds, full-color paintings of adult and juvenile birds and keys to identification. It's definitive, authoritative and weighs in at over a pound. The late Roger Tory Peterson called its publication "a red letter day for the field glass fraternity." Also recommended is Harrison's Field Guide to Seabirds of the World.  (FG01, $32.00)
