"[ T]op-notch... From the detailed records of vagrants and their identification to expert tips on how to see the likes of Humpback and Killer Whales, it is all here."--Steve Gantlett, Birding World "This book is essential for everyone who visits or lives along Britain's coasts."--Devorah Bennu, GrrlScentist "[ A]n excellent identification guide ... stuffed with useful maps, photos, tips and illustrations showing above and below-water profiles."--Birds "An essential field guide to all the sea mammals--whales, dolphins, porpoises, and seals--found in coastal Britain."--Wildlife Magazine "As a field guide this is an excellent book--including a plastic cover for the inclement weather but it is not just a field guide as it tells you about where to go, when to go and quite a lot about the ecology and conservation of the species that you might see... This book is highly recommended for the right kind of library as it will be useful to both the casual observer right up to the obsessive cetacean twitcher!"--Helen Ashton, Reference Reviews
