Designed for the field, this compact handbook features all the species of birds, seals and whales the traveler is likely to encounter on a voyage to Antarctica. It includes concise essays on each species, range maps and masterful color drawings by Dafila Scott, the granddaughter of Captain Scott. Someone was bound to write this handy field guide and we couldn't be happier that it's friend and colleague Tony Soper -- a veteran expedition leader who is as congenial as he is mad about birds. Fourth edition.  (ANT30, $21.95)
