Download or read book Skuas and Jaegers written by Klaus Malling Olsen and published by A&C Black. This book was released on 2010-09-30 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first complete identification guide to the skuas of the world. Skuas (and jaegers) are a fascinating and popular group of seabirds that make up a subfamily of just seven species. They can be divided 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 northern hemisphere. Both northern and southern skuas breed at high latitudes and several species are long-distance migrants, performing spectacular migrations through most of the world's oceans, sometimes 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 identification and correct ageing, and the information presented is based on years of study in the field, detailed examination of photographs and museum skins, and extensive research of the relevant literature. The comprehensive text is accompanied by twelve exquisite colour plates by Hans Larsson, illustrating a wide range of plumages. In addition, there are eight pages of colour photographs and numerous black and white photographs and drawings that show key identification features. With this book, the seabird enthusiast should at last be able to identify almost every skua encountered, whether on a seawatch or at sea.

Download or read book The Skuas written by Robert W. Furness and published by A&C Black. This book was released on 2010-10-30 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive monograph of the skua. Many birdwatchers may never have seen a skua; those who have will most probably have vivid memories of one or other species flying powerfully past a headland, or twisting and diving in pursuit of its piratical intentions towards a food-laden seabird - or, perhaps more memorably still, of themselves taking evasive action from the power-diving irate skua whose territory they have unwisely invaded. The full classification of the skuas is still debated, but Dr Furness of the Applied Ornithology Unit, Glasgow University, favours six species, of two genera, with five subspecies, based on current knowledge and his own long and dedicated field studies and research. All of the species are treated comparatively under the following chapter titles: Early history and classification, Distributions and populations, Migration patterns, Reversed sexual size dimorphism, Behaviour, Food and feeding, Kleptoparasitism, Plumage polymorphism, Breeding systems and social organisation, Breeding - laying to hatching, Breeding - hatching to fledging, Population dynamics, Pollutants, Skuas and agriculture, Skuas and conservation. The text is supported by 100 maps and diagrams, 30 photographs and 65 tables. In addition, John Busby contributes 35 evocative drawings which more than embellish this erudite and readable summary of an impressive and diverse group of birds. Jacket paintings by John Busby.
