Designed as a pocket-sized companion to Seabirds: An Identification Guide, this excellent reference includes over 740 photographs from more than 300 of the world's leading seabird photographers and researchers, covering all 320 or so of the world species. Most are shown in flight, a feature that makes it invaluable to any sea-watcher, for many species are rarely seen any other way. Also included are identification keys for albatrosses, petrels, shearwaters, storm- and diving-petrels.
