Owls of the World


Book Description

The definitive book on owls. Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt. This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because voice is vital in owl identification, much emphasis is placed on it in the book and sonograms are provided for many species. A CD of owl vocalisations accompanies the book.







Bat Ecology


Book Description

In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In Bat Ecology, world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research. The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals. Bat Ecology is the most comprehensive state-of-the-field collection for scientists and researchers.

The Golden Eagle


Book Description

This comprehensive monograph is a second edition of one of the most popular Poyser monographs; it covers all aspects of this spectacular eagle's biology and ecology, including a full review of the literature and incorporating the considerable body of research on the species since the publication of the first edition in 1997. The late Jeff Watson was one of Scotland's foremost eagle experts, with more than 20 years of research on the birds; following Jeff's untimely death, the book is being completed by his colleagues Des Thompson and Helen Riley. Scottish studies provide the foundation for a treatment that also includes up-to-date information from work in North America, continental Europe and elsewhere. This global view allows fascinating insights into the species' relationships with a variety of different habitats and leads to many new and important conclusions regarding its ecology. This highly readable and authoritative account is destined to become the standard reference on the species, both in Scotland and elsewhere in the world. The text is enriched with many superb pictures of this majestic bird and additional wash landscapes capture the very special atmosphere of Scotland's Golden Eagle country.
