This compact guide covers not only the many petrels, ducks, gulls, terns and other birds of the islands and inshore waters of the British Isle but also whales, dolphins, a few fish and some invertebrates. It's a handy reference for anyone sailing around the Isles. Each of the creatures is fully described with a handsome large watercolor illustration by Dan Powell. This is third in a series of guides by veteran naturalist Tony Soper to the birds, whales and other creatures encountered on the sea.  (GBR371, $19.95)
