The Avifauna of Micronesia, Its Origin, Evolution, and Distribution is a book by Rollin H. Baker. It examines the birdlife of Micronesia from a historical viewpoint and takes a look at its evolution into current biological trends.
Explore the multiple issues that surround species declines and conservation efforts through the only reference source to examine the conflicting conservation issues of 49 endangered species. While the causes of endangerment are relatively easy to understand, the ultimate or underlying factors are often far more complex and difficult to address. An introduction to these issues and how to resolve them is provided in this unique collection of case studies of animal species that have been pushed to the brink of extinction. Each case study provides the following information: - Common name - Scientific name - Order - Family - Status - Threats - Habitat - Distribution - Natural history - Conflicting Issues - Future and Prognosis. Conservationists are increasingly recognizing that the ultimate causes of extinction are primarily socio-economic and political, yet biological approaches to recovery continue to dominate. More inclusive, interdisciplinary conservation programs are explored here to offer better prospects for managing problems and conflicts. In addition to the case studies, trends and common themes are explored to provide a comprehensive, interdisciplinary approach to conservation. Students and teachers can explore a wide variety of endangered species programs and the conflicting issues common to recovery efforts, which will enable them to evaluate conservation practice and to draw their own conclusions for improvement.
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.
A summary of information on 154 species of duck, geese and swans of the world intended as an identification manual for the wildfowl enthusiast that goes beyond a regional basis and is light enough to be used as a handy reference book in the field. The text not only clarifies identification techniques but fully discusses problematic plumages in detail as well as providing a summary on world distribution and status complemented by clear distribution maps.
The Bell Vireo (Vireo bellii Aud.) is a summer resident in riparian and second-growth situations in the central United States south of North Dakota. In the last two decades this bird has become fairly common in western, and to a lesser extent in central, Indiana and is apparently shifting its breeding range eastward in that state. In northeastern Kansas the species breeds commonly and occurs in most tracts of suitable habitat. The amount of information on the ritualized behavior of the Bell Vireo and related species heretofore has been meager. The author observed breeding behavior from its inception in early May through the summer of 1960, and this report is the fruit of said labor.
