Book Description
Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

Book Description
The first book of its kind to be published for the Bluegrass State, The Birds of Kentucky is designed to provide an accurate and scientifically rigorous description of all the species of birds found in Kentucky. This comprehensive guide features a wealth of information, including abundance records, migration dates, and additional reference material, and indicates whether a bird is a permanent resident, winter resident, summer resident, visitant, or transient. Additionally, author Burt L. Monroe reviews the history of ornithologists who have worked in Kentucky and outlines the physiography of the state as it relates to birding. More than just a verbal portrait of Kentucky avifauna, The Birds of Kentucky includes fifty-one color paintings by the renowned wildlife artist William Zimmerman, whose work has been favorably compared to that of John James Audubon. In contrast to Audubon's romanticism and often tortuous style, however, Zimmerman offers us "comfortable" birds that look as if they are about to take wing and leave the page. Beautifully illustrated and based on a lifetime of field observation and research, this book provides an excellent guide to the natural history of the birds of the Bluegrass.

Book Description
- A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.
