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.

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 is the first complete identification guide to the skuas of the world. It 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.

You may not believe it, but skuas are truly some of the most disgusting creatures on the planet. Not only do these birds eat baby penguins and rotting flesh, but they harass other birds until they throw up in fear. Then they eat the vomit. Pretty disgusting! Skuas prefer to steal their meals from other birds, but they are not above attacking and killing animals if they have to. As bird bullies, skuas are big and powerful and can spend years at sea. Readers will be thrilled to learn more about these animals and their gross eating habits.

This book describes the results of a long-term study of the ecology, evolutionary genetics and sociobiology of a seabird, the Arctic Skua. This species is polymorphic: the birds show one of three, genetically different forms of plumage - pale, intermediate and dark. The forms vary in frequency from predominantly pale in the north to dark in the south. The study was undertaken with the aim of explaining how natural and sexual selection act to maintain all three forms of skua in its populations. The results show that natural selection for pale is balanced by sexual selection for intermediate and dark. Models derived from Darwin's theories of female choice and sexual selection in monogamous birds fit the breeding data of the Arctic Skua. Darwibn's views on sexual selection are fully confirmed. The study produced original data on breeding ecology, demography, population regulation, sexual behaviour and territoriality. A chapter on feeding ecology is also included in the book, which gives a complete and largely original account of the population ecology and sociobiology of a single species of bird.

The Blackburn Skua was the first monoplane to be designed and built for the Royal Navy in the 1930s. As a result of continued debate, it became a compromise between the Navys desire for a carrier-based dive-bomber and RAFs preference for a fighter. Despite being the first to shoot down a Luftwaffe aircraft in World War II, early operations in Norway found the type woefully inadequate as a fighter.As a dive-bomber, the Royal Navy put the design to good use from the outset of WWII. It was involved with the hunt for the Graff Spee, sunk the major warship Koln, suffered with great loss in an attack on the Scharnhorst, helped to keep the German advance at bay during the Dunkirk evacuation and attacked the French rogue battleship Richelieu in the Mediterranean.This book relates how the final design was created, how the dive-bombing technique was developed and perfected by naval pilots and traces the wartime operational career of the type with many first-hand accounts.
