Available in PDF, EPUB and Kindle. Book excerpt: Bayesian inference facilitated structured interpretation of a nonreplicated, experience-based survey of potential nesting habitat for bald eagles (Haliaeetus leucocephalus) along the five Great Lakes shorelines. We developed a pattern recognition (PATREC) model of our aerial search image with six habitat attributes: (a) tree cover, (b) proximity and (c) type/amount of human disturbance, (d) potential foraging habitat/shoreline irregularity, and suitable trees for (e) perching and (f) nesting. Tree cover greater than 10 percent, human disturbance more than 0.8 km away, a ratio of total to linear shoreline distance greater than 2.0, and suitable perch and nest trees were prerequisite for good eagle habitat (having sufficient physical attributes for bald eagle nesting). The estimated probability of good habitat was high (96 percent) when all attributes were optimal, and nonexistent (0 percent) when none of the model attributes were present. Of the 117 active bald eagle nests along the Great Lakes shorelines in 1992, 82 percent were in habitat classified as good. While our PATREC model provides a method for consistent interpretation of subjective surveyor experience, it also facilitates future management of bald eagle nesting habitat along Great Lakes shorelines by providing insight into the number, type, and relative importance of key habitat attributes. This practical application of Bayesian inference demonstrates the technique's advantages for effectively incorporating available expertise, detailing model development processes, enabling exploratory simulations, and facilitating long-term ecosystem monitoring.

Available in PDF, EPUB and Kindle. Book excerpt: Nest occupancy and reproductive success of the large breeding populations of bald eagles (Haliaeetus leucocephalus) within parks in the Southwest Alaska Network (SWAN), including Katmai National Park & Preserve (KATM), have been selected as a “vital sign” for monitoring as they are indicative of the health of both freshwater and marine ecosystems. Records of nesting activity were collected from 1974-1997 in KATM, but monitoring lapsed from 1998- 2010. In 2011, we reinitiated eagle surveys in KATM following a standardized sampling protocol with an initial double-count aerial survey in May to determine nest locations and occupancy, and a follow-up survey in July to assess productivity. Objectives of this report were to: (1) map all empty and incubating eagle nests located in the Naknek drainage of KATM in 2011, (2) summarize historic KATM bald eagle nesting data, and (3) discuss techniques that can be used for future consistent monitoring.

Book excerpt: River and streams in the lower Susitna River basin were surveyed by plane to obtain information on nesting bald eagles in response to proposed timber leasing in those areas. The survey included the Susitna River and some of its tributaries as well as neighboring rivers outside that drainage basin: Chuitna River, Beluga River, Little Susitna River. Sighted locations are matched to those of surveys made 1980 to 1983.
