Available in PDF, EPUB and Kindle. Book excerpt: The story of one woman’s remarkable work with a trio of charismatic, endangered bird species—and her discoveries about the devastating threats that imperil them. In Feather Trails, wildlife biologist and birder Sophie A. H. Osborn reveals how the harmful environmental choices we’ve made—including pesticide use, the introduction of invasive species, lead poisoning, and habitat destruction—have decimated Peregrine Falcons, Hawaiian Crows, and California Condors. In the Rocky Mountains, the cloud forests of Hawai’i, and the Grand Canyon, Sophie and her colleagues work day-to-day to try to reintroduce these birds to the wild, even when it seems that the odds are steeply stacked against their survival. With humor and suspense, Feather Trails introduces us to the fascinating behaviors and unique personalities of Sophie’s avian charges and shows that what endangers them ultimately threatens all life on our planet. More than a deeply researched environmental investigation, Feather Trails is also a personal journey and human story, in which Sophie overcomes her own obstacles—among them heat exhaustion, poachers, rattlesnakes, and chauvinism. Ultimately, Feather Trails is an inspiring, poignant narrative about endangered birds and how our choices can help to ensure a future not only for the rarest species, but for us too. "An intimate look at the wonder and effort needed for working with endangered species in the wild. [Osborn's] matter-of-fact writing style and wry humor make the reader part of the action."—Booklist (starred review)

Available in PDF, EPUB and Kindle. Book excerpt: Point counts of birds are the most widely used quantitative method and involve an observer recording birds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, researchers met to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. The final chapter presents these standards and their applications to point count methodology.

Available in PDF, EPUB and Kindle. Book excerpt: « Think about how we know about past events in human history (e.g., the expansion of the Roman Empire, or the American Revolution). What types of records document those events? Now think about Earth's history, specifically the past environmental or climatic conditions at times before recorded human history. What records might there be of such conditions? Make a list of your ideas. n assemblage of five major types of natural archives of Earth's environmental and climatic history. What common feature(s) do each of these paleoclimate archives share? an assemblage of 5 major types of natural records, or archives, of Earth's environmental and climatic history. Just like a diary or other historical document, the layers in these natural archives contain indirect evidence (i.e., proxies) about past conditions and events, recorded in a sequential order. The evidence is specific to a certain time period and may be general or very detailed, depending on the rate that information was recorded. The faster the rate at which the recorder grew (trees and corals), accumulated (snow and ice), or was deposited (sedimentary sequences), the more detailed the record is, and the higher its resolution. For example, a record in which an annual signal can observed has a very high resolution. In contrast, if the finest observable details are on the order of a million years, then that record would have a low resolution. »--
