This comprehensive overview of the habitats, plants, birds, and animals of the islands, written with the curious visitor in mind, is practically mandatory reading. It's the single best overview of the archipelago. Jackson also includes a useful bibliography, wildlife checklists and a list of plants by vegetation zone. Illustrated with many charts and maps, we refer to the book often.  (GPS03, $29.95)
