ISBN XXXXXXXXXXXX Cover photo by David Predeger. 1 Preface Marshall Lind Chancellor, University of Alaska, Southeast, Juneau, Alaska As one who never tires of the presence of Bald Eagles in our Alaskan environment, it is a particular pleasure for me to introduce this unique book. I feel confident you will share my enthusiasm as you read through Bald Eagles in Alaska. The book is unique because almost all of the authors are long time Alaskans who know Bald Eagles, not as an endangered species, but as an integral part of the avifauna of the 49th state. Chapters in this text present a range of topics on culture, conservation and management as well as sound scientific data. Various papers cover the Alaska habitat from the northern rainforest to the treeless Aleutian Islands. Diverse human attitudes are presented from the Tlingit Indians to the bounty hunters; from the modern conservationists of Haines to the ambitious people of New York who are trying to replace their diminished eagle population with Bald Eagle stock from Alaska. In short, Bald Eagles in Alaska offers the best portrait that has ever been assembled in the status and ecology of Bald Eagles in Alaska.

You can read from cover to cover or browse here and there from chapter to chapter. In either case, you will have a rewarding experience whether you are a casual reader, a biology student or a raptor scientist. As a bonus, you will get a bit of a sense of the enthusiastic reverence Alaskans (and some neigh- bors from Canada and other states) feel for their land and its resources. The genesis of this fine volume was at a Juneau conference in November, 1990, hosted by the American Bald Eagle Research Institute of the University of Alaska, Southeast (UAS). The objective was to produce a reader to complement the correspondence study course in Bald Eagles offered by the biology department at UAS and to produce a compendium of the most current information on Bald Eagles of Alaska and Yukon for use by the scientific community and enjoyment of the general public. My thanks to all the splendid authors who present their work here and my warmest regards to all the Bald Eagle enthusiasts who read this book. 2 Forward Bruce A. Wright1,2 James G. King3 and G. Vernon Byrd4 1Aleutian Pribilof Islands Association, 2Conservation Science Institute, 3U.S. Fish and Wildlife Service, retired, 4Alaska Maritime NWR, 95 Sterling Hwy, Homer, AK 99603 In November 1990 the University of Alaska, Southeast (UAS) and the Bald Eagle Research Institute hosted a symposium on Bald Eagles in Juneau, Alaska. The original intent was to provide a reader for the UAS correspondence study course, Bald Eagles in Alaska's Coastal Rain Forest, but there was also a plan to publish the proceedings. For various reasons, the work was not published in a timely fashion. After the passage of so many years, we almost abandoned this project because only “hard copies” of original contributions were available. Nevertheless, our “ad hoc” team decided that the information contained in these papers is important enough to justify the time and energy required to produce this book. We could not have done it without the significant contribution of Sharon Baur at Alaska Maritime National Wildlife Refuge, who methodically scanned every page, photograph and graphic from the only extant complete set of manuscripts. Clearly, additional information has been learned about eagles in Alaska since these papers were written in 1990, but we have not asked all authors to update their contributions from the original symposium. Indeed some of the authors are now deceased. We did include some recent, invited contributions to make the volume a more complete picture of Alaska’s Bald Eagles at the end of the 20th century. All papers have been peer reviewed. We believe this book is still the best compilation of information about Bald Eagles in Alaska and therefore will be useful to scientists, resource managers, students and the public. Therefore we are pleased to offer this compilation to major libraries in Alaska and via the internet. The volume should be cited as: Wright, B. A. and P. F. Schempf, eds. 2008. Bald Eagles in Alaska.

PUB DATE 2002-00-00 NOTE 18p.; Paper presented at Uplands Retirement Community (Pleasant Hill, TN, June 17, 2002). PUB TYPE Opinion Papers (120) EDRS PRICE EDRS Price MF01/PC01 Plus Postage. DESCRIPTORS *Authors; *Biographies; *Educational Background; Popular Culture; Primary Sources; Social Studies IDENTIFIERS *Conversation; Educators; Historical Research; *Michener (James A); Pennsylvania (Doylestown); Philanthropists ABSTRACT This paper presents an imaginary conversation between an interviewer and the novelist, James Michener (1907-1997). Starting with Michener's early life experiences in Doylestown (Pennsylvania), the conversation includes his family's poverty, his wanderings across the United States, and his reading at the local public library. The dialogue includes his education at Swarthmore College (Pennsylvania), St. Andrews University (Scotland), Colorado State University (Fort Collins, Colorado) where he became a social studies teacher, and Harvard (Cambridge, Massachusetts) where he pursued, but did not complete, a Ph.D. in education. Michener's experiences as a textbook editor at Macmillan Publishers and in the U.S. Navy during World War II are part of the discourse. The exchange elaborates on how Michener began to write fiction, focuses on his great success as a writer, and notes that he and his wife donated over $100 million to educational institutions over the years. Lists five selected works about James Michener and provides a year-by-year Internet search on the author.(BT) Reproductions supplied by EDRS are the best that can be made from the original document.

  • Gunshot Wounds: a Source of Lead in the Environment
    GUNSHOT WOUNDS: A SOURCE OF LEAD IN THE ENVIRONMENT 1 2 RICHARD K. STROUD AND W. GRAINGER HUNT 1US Fish & Wildlife Service, National Forensics Laboratory 1490 East Main Street, Ashland, OR 97520-1310 USA 2The Peregrine Fund, 5668 West Flying Hawk Lane, Boise ID 96056 USA E-mail: [email protected] ABSTRACT.—Ingested lead shotgun pellets and rifle bullet fragments have been shown to be an important source of lead poisoning in water birds, raptors, avian scavengers, and even seed-eating birds. Ingestion of spent lead shotgun pellets by waterfowl and secondary ingestion by Bald Eagles (Haliaeetus leucocepha- lus) scavenging on waterfowl led to the change of hunting regulations that prohibit the use of toxic lead pellets for waterfowl hunting in the United States. However, bullets containing toxic lead are still widely used to hunt large game animals and “varmints” and are a source of lead in the environment available to wildlife. Basic bullet materials available to the bullet manufacturer include lead alloys, lead with external copper wash, lead core with copper jacket, pure copper, and bismuth. Lead and bismuth are highly frangible, whereas pure copper bullets tend to remain intact after impact. Bullet fragmentation increases the degree of lead contamination in tissue ingested by scavengers feeding on hunter-killed animal remains. Modern bullet design, velocity, composition, and bone impact are significant factors in the character and distribution of lead particles in carcasses, gut piles, and wound tissue left in the field by hunters. Prior to the 1900s, bullets were made entirely of lead. Their velocities were relatively slow (<2000 feet per second), and their ten- dency to fragment was accordingly lower than that of modern ammunition.

  • INTRODUCTION 1. in Explanation of His Point, Sperry Writes: 'It Is Not Just
    Notes INTRODUCTION 1. In explanation of his point, Sperry writes: 'It is not just that the poetry is taken up in isolation from the life of the poet, from the deeper logic of his career both in itself and in relation to the history of his times, although that fact is continuously disconcerting. It is further that in reducing the verse to a structure of ideas, criticism has gone far toward depriving it of all emotional reality'(14). 2. See, in particular, Federico Olivero's essays on Shelley and Ve­ nice (1909: 217-25), Shelley and Dante, Petrarch and the Italian countryside (1913: 123-76), Epipsychidion (1918: 379-92), Shelley and Turner (1935); Corrado Zacchetti's Shelley e Dante (1922); and Maria De Courten's Percy Bysshe Shelley e l'Italia (1923). A more recent, and important, work is Aurelio Zanco's monograph, Shelley e l'Italia (1945). Other studies of note are by Tirinelli (1893); Fontanarosa (1897); Bernheimer (1920); Bini (1927); and Viviani della Robbia (1936). 3. In researching this field of study, Italian critics have found Shelley to be their best spokesman. 4. A work such as Anna Benneson McMahan's With Shelley in Italy (1907) comes to mind. Hers is a more inclusive anthology than John Lehmann's Shelley in Italy (1947) but needs to be brought up to date. 5. There has been a growing recognition of the importance of the Italian element in Shelley's poetry. Significant studies in English since those of Scudder (1895: 96-114), Toynbee (1909: 214-30), Bradley (1914: 441-56) and Stawell (1914: 104-31) are those of P.

  • Pacific Seabird Program Business Plan (Dawson Et Al
    National Fish and Wildlife Foundation Business Plan for Pacific Seabirds (Update) September 2016 Pacific Seabirds | 1 Purpose of a Business Plan The purpose of a NFWF business plan is to provide a detailed blueprint of the strategies and resources required to achieve the desired conservation outcomes. The strategies discussed in this plan do not represent solely the Foundation’s view of the actions necessary to achieve the identified conservation goals, but instead reflect the majority view of the many federal, state, academic, and organizational experts that were consulted during plan development. This plan is not meant to duplicate ongoing work but rather to invest in areas where gaps might exist so as to support the efforts of the larger conservation community. Acknowledgements We thank everyone who contributed to this business plan. We are especially grateful to the seabird experts, funding partners, and working group teams who took the time to develop, contribute, and review material. We acknowledge the contributions of Dantzker Consulting, Advanced Conservation Strategies, and Clarus Research for their evaluation of the Pacific Seabird Program and recommendations for continued implementation of this program. We also wish to acknowledge the valuable input resulting from discussions and written material provided by implementation and funding partners including (but not limited to): The American Bird Conservancy, BirdLife International, The David and Lucille Packard Foundation, The Farallon Institute, Island Conservation, the National Audubon Society, National Park Service, National Oceanographic and Atmospheric Administration, Oikonos, University of California Santa Cruz Coastal Conservation Action Lab, The University of Washington, The U.S. Fish and Wildlife Service, The U.S.

(Bob) Hakala Visitor Information Service Illustrations by Ann Pritchard Surveys and Maps U.S.D.A. Forest Service Juneau, Alaska TO OUR VISITORS The messages in this booklet have been heard by thousands of travelers to Southeast Alaska. They were prepared originally as tape recordings to be broadcast by means of message repeater systems on board the Alaska State ferries and commercial cruise vessels plying the Alaska waters of the Inside Passage. Public interest caused us to publish them in this form so they would be available to anyone on ships traveling through the Tongass country. The U.S.D.A. Forest Service, in cooperation with the State of Alaska, has developed the interpretive program for the Alaska Marine Highway (Inside Passage) because, as one of the messages says, "... most of the landward view is National Forest. The Forest Service and the State of Alaska share the objective of providing factual, meaning­ ful information which adds understanding and pride in Alaska and the National Forests within its boundaries."
