"Filled with concise information and accurate illustrations, this terrific field guide will be a handy, quick reference for the layperson and serious naturalist on boat trips off the West Coast of the United States. No other useful guides for this region deal with both marine mammals and seabirds in the same book."--Sophie Webb, coauthor of Field Guide to Marine Mammals of the Pacific Coast
"Intended for beginner- and moderate-level naturalists as well as tourists on whale-watching and birding trips, this field guide presents a fresh, new format. Images are nicely formatted and the text is clear, light, and humorous while being informative and scientifically accurate."--Peter Pyle, author of Identification Guide to North American Birds
