Download or read book Coloniality in the Cliff Swallow written by Charles R. Brown and published by University of Chicago Press. This book was released on 1996-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many animal species live and breed in colonies. Although biologists have documented numerous costs and benefits of group living, such as increased competition for limited resources and more pairs of eyes to watch for predators, they often still do not agree on why coloniality evolved in the first place. Drawing on their twelve-year study of a population of cliff swallows in Nebraska, the Browns investigate twenty-six social and ecological costs and benefits of coloniality, many never before addressed in a systematic way for any species. They explore how these costs and benefits are reflected in reproductive success and survivorship, and speculate on the evolution of cliff swallow coloniality. This work, the most comprehensive and detailed study of vertebrate coloniality to date, will be of interest to all who study social animals, including behavioral ecologists, population biologists, ornithologists, and parasitologists. Its focus on the evolution of coloniality will also appeal to evolutionary biologists and to psychologists studying decision making in animals.

Download or read book The Barn Swallow written by Angela Turner and published by A&C Black. This book was released on 2010-01-29 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Barn Swallow is a familiar and popular bird throughout the world. It is one of the most widely distributed bird species, breeding in North America, Europe, Asia and North Africa and wintering in South America, southern Africa, southern Asia and even northern Australia. Its habit of nesting close to human habitation has made this elegant bird a part of farmyard and village life and a welcome herald of spring. This book examines all aspects of the life of this endearing bird, with chapters on its flying skills and feeding habits, mate choice, breeding strategies, nest sites, eggs and incubation, nestling rearing, productivity and survival, migratory behaviour and population dynamics. It also considers changes in populations and behaviour in relation to intensive agriculture and climate change. The Barn Swallow is both engaging and authoritative; birdwatchers will enjoy amazing insights into the life of the species, such as the importance of tail feathers when finding a mate, or the sinister way that some birds kill of the chicks of rivals. Academic scholars will appreciate the book's broad overview of current research on this species.

Download or read book A Handbook to the Swallows and Martins of the World written by Angela Turner and published by A&C Black. This book was released on 2010-06-30 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference guide gives general details about the swallows and martins of the world. These include appearance, the basic coloration and differences between the sexes and immatures and the function of other areas of colouring. Several species within the same geographical area are often segregated by feeding in different habitats or at different heights or by eating different size-classes of insects. The two sub-families, one being the two river martins, the other containing about 72 species mainly in the genus hirundo, are dealt with, including their distribution and migration patterns. Feeding, courtship and breeding habits are considered, together with details of nesting sites, clutch size, incubation and life-span. Finally, the population sizes of the various species are examined, noting that whilst many have expanded their range by using man-made structures, forest species probably remain small and one species, the Red Sea swallow is known from only one specimen. The book follows the same approach, style and presentation as The Herons Handbook published in 1985. It is illustrated by the winner of the prestigious British Birds Illustrator of the Year Award and the author has contributed to many scientific papers and journals including BBC's Wildlife Magazine.
