Ecology and Evolution of Cooperative Breeding in Birds

Ecology and Evolution of Cooperative Breeding in Birds PDF Author: Walter D. Koenig
Publisher: Cambridge University Press
ISBN: 9780521530996
Category : Juvenile Nonfiction
Languages : en
Pages : 308

Book Description
Cooperative breeders are species in which more than a pair of individuals assist in the production of young. Cooperative breeding is found in only a few hundred bird species world-wide, and understanding this often strikingly altruistic behaviour has remained an important challenge in behavioural ecology for over 30 years. This book highlights the theoretical, empirical and technical advances that have taken place in the field of cooperative breeding research since the publication of the seminal work Cooperative Breeding in Birds: Long-term Studies of Behavior and Ecology (1990, HB ISBN 0521 372984, PB ISBN 0521 378907). Organized conceptually, special attention is given to ways in which cooperative breeders have proved fertile subjects for testing modern advances to classic evolutionary problems including those of sexual selection, sex-ratio manipulation, life-history evolution, partitioning of reproduction and incest avoidance. It will be of interest to both students and researchers interested in behaviour and ecology.

Hawk Ridge

Hawk Ridge PDF Author: Laura Erickson
Publisher: U of Minnesota Press
ISBN: 0816681198
Category : Nature
Languages : en
Pages : 106

Book Description
Was Caesar like the eagle because of his aquiline (from aquila, for “eagle” in Latin) nose, or does the eagle seem imperial because of his Caesar-like beak? Does the sharp vision of a “hawk-eyed” observer have any basis in nature? And what the heck is “kettling” to a bird-watcher, or, for that matter, a bird? Raptors have captured the imagination from time immemorial and have an especially rich history in Minnesota. The ancient peoples whose pictographs adorn the rock faces of Lake Superior's North Shore may well have witnessed the first hawk movements along Lake Superior—the same annual migration that today draws as many as twenty thousand people to Duluth's Hawk Ridge. These birds, passing through in astounding numbers, are among the hawks and accipiters, buteos and harriers, eagles and ospreys pictured and profiled in detail in this book. Written by one of Minnesota's best-known bird authorities, with images by one of the state's favorite illustrators, Hawk Ridge is as fun as it is informative. It introduces the state's raptors, from the rare visitor to the most familiar hawk, noting each species' signature traits—osprey wings, for instance, are crooked to help them catch fish; vultures urinate on their legs to cool themselves—and their nesting, breeding, and migrating habits. Did you know that Sharp-shinned Hawks banded at Hawk Ridge have been found throughout Central America and even into South America, and also, in midwinter, in Wisconsin? Laura Erickson offers a broad perspective (a bird's-eye view!), making sense of the raptor's role in the larger ornithological scheme. With descriptions of various species—and helpful distinctions between species, families, and orders—the book gives readers a clear idea of which raptors might be seen in Minnesota, when, where, and how often. It also includes a hawk migration primer that explains the movements that bring these birds in such awe-inspiring numbers to places like Hawk Ridge. Filled with curious facts and practical information for expert and amateur bird-watcher alike, the book is at once a guide to the hawks of Minnesota and a beautifully illustrated album of the most regal members of the avian kingdom.

The Breeding Bird Atlas of Georgia

The Breeding Bird Atlas of Georgia PDF Author: Todd M. Schneider
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 532

Book Description
This is a comprehensive historical record of all free-ranging bird species known to be breeding in Georgia around the beginning of the new millennium. The atlas profiles 182 species, from the sociable House Wren to the secretive Black Rail; from the thriving Red-shouldered Hawk to the threatened Wilson's Plover. The atlas is the result of a systematic survey conducted from 1994 to 2001, the massive collaborative effort of several private organizations, public agencies, and many individuals. It offers a wealth of information critical to bird-conservation efforts and provides a baseline so that changes to species ranges, numbers, and other significant aspects of each species' status can be better understood. Each species account includes: Color photograph of the bird Information on the bird's habitat and life history, distribution, population trends, and conservation status. Details discussed include diet, nesting habits, life cycle of the young, predators, and interactions with humans. Color distribution map showing the state's six ecoregions and indicating possible, probable, and confirmed breeding Graphs showing population trends, when appropriate Also included are chapters on the survey methodology, results of the surveys, influence of the physical environments of the state on bird distribution, changes in the avifauna since European settlement, and bird conservation.
