Sadly, this crucial stopover along the Pacific Flyway for migratory and wintering shorebirds, landbirds, and waterfowl is dangerously close to collapse from several environmental threats. This book is the first thoroughly detailed book to describe the birds of Salton Sea, more than 450 species and subspecies in all. A major contribution to...

The Ruff
de Johan Van Rhijn (Ed. Poyser) Isbn : 0856610623
49.17 € / 322.53 FF
The ruff is a species of bird whose elaborate breeding behaviour has fascinated ornithologists for decades. Their communal display ground, or leks, provide an extreme example of a social system widespread in birds and other animals, in which brilliantly plumaged males seemingly compete for the attention of passing females. In this book, Johan van Rhijn explores this complex and intricate behavioural pattern, both to lay bare the details of the players private lives, and to provide a means of exploring the wider variety of wader breeding systems. Strands of evidence for all aspects of the ruff's life, in and out of the breeding season, come together to give an insight into this important area of biology. Specialists and birdwatchers alike will find this text of interest. «The Ruff is undoub...

Polygyny and Sexual Selection in Red-Winged Blackbirds
de William A. Searcy, Ken Yasukawa (Ed. Princeton Univ Pr) Isbn : 0691036861
60.55 € / 397.18 FF
The purpose of this book is to explain why red-winged blackbirds are polygynous and to describe the effects of this mating system on other aspects of the biology of the species. Polygyny is a mating system in which individual males form long-term mating relationships with more than one female at a time. The authors show that females choose to mate polygynously because there is little cost to sharing male parental care in this species, and because females gain protection against nest predation by...
