Book Synopsis Gulls of Europe, Asia and North America by : Klaus Malling Olsen
Download or read book Gulls of Europe, Asia and North America written by Klaus Malling Olsen and published by A&C Black. This book was released on 2010-06-30 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: This eagerly awaited guide offers the most comprehensive treatment ever published on the gulls of Europe, Asia and North America. A total of 43 species is treated, and every species is described in considerable detail, with a full description of each plumage and racial variation. Gulls are intelligent, versatile, opportunistic, and ecological generalists. As such, they exploit a variety of habitats, both coastal and inland, take a wide range of food, and are often extremely abundant. They are also great wanderers, with several American species regularly appearing in Western Europe and vice versa. As well as identification criteria, this book includes an up-to-date assessment of the range and status of every species, together with information on patterns of vagrancy. This important guide is published at a critical time in the development of dull taxonomy. The large, white-headed forms occurring in the region comprise a superspecies complex, with the precise relationships between the various components still under considerable debate. A thorough illustrative and textual treatment of the group is much needed, and this book provided the most complete overview of the complex. The text is complemented not only by superb colour paintings by Hans Larrson, but also by a large selection of colour photographs, sourced from some of the finest bird photographers in the world. This is the essential reference to a fascinating and endlessly challenging group of birds.
Download or read book Gulls and Plovers written by C.J. Barnard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early years of this century a Scottish doctor speculated on the evolutionary origin of human tears. It seemed to him that with the increase in brain size and cognitive powers of our early ancestors many events in the struggle for existence would be just too distressing to observe. How comforting then, for the mother, distraught by the sight of her child being devoured by a lion, to cloud her vision with a flood of tears! Just so, though if the good doctor had pondered further, the following picture might have occurred to him, comfortable in his speculative armchair, and given him some pause for thought. ' ~ . . . . ~ . . ~ ~ . . •. . u" . . , ~- . ' _ . . . . . . . vii viii SERIES EDITOR'S FOREWORD These stories do not, of course, get us very far in understanding the evolution of tears or anything else, but they do remind us how far the study of behavioural adaptation has come this century. This is, in fact, an exciting time for students of behaviour. The last twenty years have seen a great advance in the theoretical armoury for tackling questions of behavioural evolution and adaptation, and a parallel expansion in empirical studies, particularly in the field. The concepts of inclusive fitness and the evolutionarily stable strategy, for example, have helped to explain major features of social behaviour and have generated entirely new questions and predictions for the field worker to examine.

Book Synopsis Two Gulls and a Girl by : Roxanne Schinas
Download or read book Two Gulls and a Girl written by Roxanne Schinas and published by Imperator Publishing. This book was released on 2008-12-31 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roxanne Schinas has always had a passion for wildlife. Long before she was old enough to read of Gerald Durrell's adventures she was emulating them, with pets ranging from rabbits and half-tame hedgehogs to toads, sticklebacks, locusts, and a crayfish. In the spring of 2008, while her family were cruising in southern Spain, Roxanne decided to make a survey of the seagull colony on an uninhabited island. The project began with a hand-drawn map on which the nests were plotted. Phase two was to have consisted in the study of the young birds growing up on the island, but when a local nature warden told her that most of the chicks would die, Roxanne found that she had a perfect excuse for "rescuing" two and bringing them home. Mother was not impressed... but the deed was done, and now the young naturalist had the opportunity to study, intimately, the development of Larus Cachinanns, the yellow-legged gull. Two Gulls and a Girl is Roxanne's record of events in the seagull colony and amongst her two hand-reared birds. Contains 92 black-and-white photos and illustrations. Foreword by Richard Williamson.
