A state-of-the-art photographic field guide to the world's oceanic birdsOceanic birds are among the most remarkable but least known of all birds, living at sea, far from the sight of most people. They offer unusual identification challenges-many species look similar and it can be difficult to get good views of fast-flying birds from a moving boat. The first field guide to the world's oceanic birds in more than two decades, this exciting and authoritative book draws on decades of firsthand experience on the open seas. It features clear text filled with original insights and new information and more than 2,200 carefully chosen color images that bring the ocean and its remarkable winged inhabitants to life. Never before have oceanic birds been presented in such an accessible and comprehensive way.The introduction discusses the many recent developments in seabird taxonomy, which are incorporated into the species accounts, and these accounts are arranged into groups that aid field identification. Each group and species complex has an introductory overview of its identification challenges, illustrated with clear comparative photos. The text describes flight manner, plumage variation related to age and molt, seasonal occurrence patterns, migration routes, and many other features.The result is an indispensable guide for exploring birding's last great frontier.A comprehensive, authoritative, and accessible guide to oceanic birdsCovers more than 270 speciesIncludes more than 2,200 color photos with concise captions noting key featuresFeatures careful species comparisons, overviews of the latest taxonomy, tips on how to observe and ID birds at sea, and much more Aucune description trouvée dans une bibliothèque |

The taxonomy of these birds is divided into: penguins, alcids, diving petrels, petrels, albatrosses, storm-petrels, tropicbirds, frigatebirds, gannets and boobies, skuas and jaegers, gulls and terns, and phalaropes. I have not even heard of most of the categories, so most of these birds look very foreign, unlike the gulls and penguins that are pretty dominant in popular culture. In fact, they are so rare in both scientific and popular discussions that the authors had to invent some of their names: “Few groups of birds have had a more-checkered taxonomic history than seabirds. We have used familiar and established names for the most part, but in some cases we had to coin new names for taxa that lacked them” (8). Abbreviations and terms used are explained in the introductory pages: this is necessary given the complex nature of this topic for the general public (11-2). The text is brief and to-the-point throughout, so that the section on conservation only takes up half-a-page; perhaps such brevity is more convincing than a long lecture, as most college lecturers can attest (29). It appears most of the photographs taken on research missions were turned into paintings, especially since the artist had to create several perspectives of each bird and different ages and sexes, even if they might have only captured a single snapshot from a single perspective on film (90). These paintings are tastefully executed, and are precise in their research, as tiny differentiations between some similar species are stressed. The feeding and other habits are curious to read; for example, the gadfly petrels “Feed by snatching fish and squid near the surface, and by scavenging… Most species nest in burrows and crevices and visit colonies at night…” (92). It is clear the book is written by a team that spent a lot of time actually trying to distinguish these birds at sea, as they describe their distinctions with careful precision. For example, when writing about Wedge-tailed Shearwater birds, they note: “In calm, flight typically unhurried, with wings pressed forward and slightly crooked; wingbeats shallow and easy, interspersed with buoyant glides on arched wings; wheels easily in strong winds, but generally in low arcs, not towering high like heavy-bodied species” (174). Too often writers simplify all birds by describing them flying or their long beaks picking at bits of food, but writers who are more interested in writing a Moby-Dick-sized novel about the sea should find these types of descriptions helpful in learning specific behaviors and characteristics, which can then be utilized in a manner that fits the symbolic or narrative needs of a story.
This is an outstanding book that should be an enjoyable addition for most libraries’ patrons. Anybody with a boat who travels across oceans should also have this guide handy in case they spot a bird and want to figure out what it is, either because they are fishing and its identity might help them figure out what fish might be around, or just to pass the time while learning a bit about their airy neighbors.
