Ă propos de ce livre
This is the first complete identification guide to the skuas of the world. Skuas (and jaegers) are a fascinating and Âpopular group of seabirds that make up a subfamily of just seven species. They can be Âdivided into two main groups: the larger species of Catharacta skuas which are mainly found in the southern hemisphere (with Great Skua breeding in the north), and the three Stercorarius species (also known as jaegers) which breed in the Ânorthern hemisphere. Both northern and southern skuas breed at high latitudes and several Âspecies are long-distance migrants, Âperforming spectacular migrations through most of the world's oceans, Âsometimes even flying overland. The individual plumage variation in some species is enormous, creating one of the most puzzling yet fascinating challenges in modern field identification. This guide is designed to enable species Âidentification and correct Âageing, and the information presented is based on years of study in the field, detailed examination of photographs and Âmuseum skins, and Âextensive research of the Ârelevant literature. The comprehensive text is accompanied by twelve exquisite colour plates by Hans Larsson, illustrating a wide range of plumages. In Âaddition, there are eight pages of colour Âphotographs and numerous black and white photographs and drawings that show key Âidentification Âfeatures. With this book, the seabird enthusiast should at last be able to Âidentify almost every skua encountered, whether on a seawatch or at sea.
