Yellowstone Bird Report, 1999. National Park Service, Yellowstone Center for Resources, Yellowstone National Park, Wyoming, YCR–NR–2000–02. Cover: Special thanks to my wife, Karen McEneaney, for the stunning pencil drawing of a Golden Eagle (Aquila chrysaetos) talon. The Golden Eagle is one of Yellowstone’s most formidable avian predators. When viewing Golden Eagle talons up close, one soon realizes why the bird is a force to be reckoned with in the natural world. Title page: Great Horned Owlet.

XXVIII No. 1 APRIL 2018 Changes to Migratory Bird Treaty Act weaken bird protections The Migratory Bird Treaty Act (MBTA), signed into law in 1918, is among the oldest and most effective wildlife protection laws on the books. When Congress passed the MBTA in 1918, it codified a treaty already signed with Canada, then part of Great Britain. The Treaty was in response to the serious overharvest of numerous bird species that had resulted in extinction in a few instances and near extinction in some species. Since 1918, the MBTA has broadened its international scope through treaties with Mexico, Japan, and Russia. The MBTA is credited with saving numerous species from extinction, including Trumpeter Swans. It continues to protect nearly all native birds in the U.S. covering more than 1,000 species, including Trumpeter Swans. The Department of Interior made significant changes to the Legislation in Congress (HR 4239), and a new interpretation interpretation of the century-old Migratory Bird Treaty Act. Photo by Margaret Smith of the law by the Administration, would end the ability to hold industries accountable for bird deaths. Industries would only be held accountable if their intention or purpose was to harm birds through their activities. This rolls back decades of bipartisan support and interpretation of the MBTA. It also removes industry incentives to prevent bird deaths and its associated penalties. -

Higher status scores denote taxa with known declining trends. Status scores range from -20 (increasing) to 20 (decreasing). Score Population Trend in Alaska (-10 to 10) 2 Trumpeter swans were nearly driven to extinction in the early 1900s due to overhunting. They have recovered since then, and in Alaska have exhibited an average annual increase of +5.3% per year from 1968 to 2015 (i.e. since USFWS surveys began; Groves 2017). This growth rate has slowed in recent decades and the population appears to have stabilized since 2005 (Groves 2017; D. Groves, pers. comm.). Distribution Trend in Alaska (-10 to 10) -10 Over the past 50 years, trumpeter swans have expanded their distribution, both within the core and the peripheries of their Alaskan range (Conant et al. 2002). The population now occupies much of the suitable habitat within Alaska's boreal forest and appears to be reaching carrying capacity in some parts of the state (Groves 2017). Further significant expansion within their core breeding range is unlikely; however, the population has continued to expand into peripheral boreal-tundra ecotone habitat (Bryant et al. -

Sterna Hirundo)
Vol. 1931XLVIII1 j JACKSONANDALLAN, C0•/gat/• ofTer•. 17 EXPERIMENT IN THE KECOLONIZATION OF THE COMMON TERN • (STERNA HIRUNDO). BY C. F. JACKSON AND PHILIP F. ALLAN. DURINGthe summerof 1929an attemptwas made at the Marine ZoologicalLaboratory at the Islesof Shoalsto establisha colony of Terns (Sternahitundo) on North Head of AppledoreIsland. This colonization was tried because of the threatened destruction of the colonyon Londoner'sIsland. The first recordsof a colonyof thesebirds at the Shoalscome from two of the oldest inhabitants. "Uncle" Oscar Leighton, ninety-oneyears of age, recalls a colony on Duck Island where thousandsof "mackerelgulls" nestedyearly. In his boyhood the fishermenused to collectthe eggsfor food,and the men and youthsshot the adults for the feathers. This colonypersisted until 1898 when "Captain" Caswellmoved to Duck Island. As a resultof this disturbance,the colonymigrated "down the Maine Coast" and settledon variousislands. In 1922a few pairsstarted nestingon Londoner'sIsland. This new colonyincreased rapidly and duringthe summerof 1928approximately one thousandpairs were breeding on the island. The year after the establishmentof the colony,a cottagewas erectedon the'island. The cottage,however, was not occupied to any extent until the summerof 1927. At this time the island wassold and the newowner, not desiringthe presenceof the birds, set aboutto drive them from the island. The eggswere destroyed, the youngwere killed, and the adultskept in a state of constant confusion. During the summerof 1929 large numbersof eggs were broken,and numerousyoung were killed. A dog was kept rovingthe islandand nosedout and killed many of the fledglings, and a flockof hensdestroyed great numbers of eggs. Althoughthe situationwas unfortunate, the ownerwas evidently well within his rightsin destroyingthe birdson his own property. -

Seabird Curriculum Book, by the Alaska
LEARN ABOUT SEABIRDS DEAR EDUCATOR, The U.S. Fish and Wildlife Service believes that education plays a vital role in preparing young Alaskans to make wise decisions about fish and wildlife resource issues. The Service in Alaska has developed several educational curricula including “Teach about Geese,” “Wetlands and Wildlife,” and “The Role of Fire in Alaska.” The goal of these curricula is to teach students about Alaska’s natural resource topics so they will have the information and skills necessary to make informed decisions in the future. Many species of seabirds are found in Alaska; about 86 percent of the total U.S. population of seabirds occur here. Seabirds are an important socioeconomic resource in Alaska. Seabirds are vulnerable to impacts, some caused by people and others caused by animals. The “Learn About Seabirds” teaching packet is designed to teach 4-6 grade Alaskans about Alaska’s seabird popula- tions, the worldwide significance of seabirds, and the impacts seabirds are vulnerable to. The “Learn About Seabirds” teaching packet includes: * A Teacher’s Background Story * 12 teaching activities * A Guide to Alaskan Seabirds * Zoobooks Seabirds * A full color poster - Help Protect Alaska’s Seabirds Topics that are covered in the packet include seabird identification, food webs, population dynam- ics, predator/prey relationships, adaptations of seabirds to their habitats, traditional uses by people, and potential adverse impacts to seabirds and their habitats. The interdisciplinary activities are sequenced so that important concepts build upon one another. Training workshops can be arranged in your region to introduce these materials to teachers and other community members.
