Merlin Migratory Species Faucon Émerillon Falco Columbarius Wingspan: M : 53 Cm to 58 Cm / F : 61 Cm to 68 Cm Merlin Migratory Species Faucon émerillon Falco columbarius Wingspan: M : 53 cm to 58 cm / F : 61 cm to 68 cm The Merlin closely resembles the Peregrine Falcon. Its back is brown or slate-blue and its tail hosts large black bands. As with most falcons, we can see black bands under the eyes, which we call "whiskers". The female is larger than the male and the bands on / her chest are broader than his. The Merlin resides mostly in conifer forests, but can sometimes be found in open spaces. The Merlin feeds on many species of birds; it is even fast enough to catch hummingbirds! It also feeds on rodents, such as mice and rats. The Merlin has a lifespan of about 10 years. The Merlin pair often uses nests abandoned by other species, such as crows, buzzards, or squirrels. The nests are often located near a source of water. The female lays 4 to 5 eggs. The young make their first flight attempt 25 to 30 days after hatching. They still remain dependant on their parents 1 to 4 weeks afterwards. The population suffered a drastic decline in the 1950s and 1960s due to the use of harmful pesticides such as DDT. Since the banning of their use in North America, the population has increased in size, but has still not rebounded to what it was before the 1950s. Birds of prey are at the top of the food chain; this is why they are most affected by the accumulation of trace pesticides distributed through the environment, such as DDT. DDT is not eliminated by animals but rather stored in their tissues. Residues accumulated in this way cause the shells of these birds’ eggs to be very thin and fragile. The egg and the chick are thus both crushed by the weight of the female as she incubates the egg. © UQROP .

McConnell Thesis Submitted in Partial Fulfillment of the Requirements for the degree of Master of Science in Wildlife Biology and Conservation University of Alaska Fairbanks May 2019 © 2019 Madison H. McConnell APPROVED: Knut Kielland, Committee Chair Greg Breed, Committee Member John Shook, Committee Member Kris Hundertmark, Chair Department of Biology and Wildlife Leah Berman, Dean College of Natural Science and Mathematics Michael Castellini, Dean of the Graduate School Abstract I studied the diet, breeding success, detectability, and density of great horned owls (Bubo virginianus) in the Middle Fork of the Koyukuk Valley in Arctic Alaska. The study extended from the southern slopes of the Brooks Range to latitudinal tree line, the northern breeding limit of the species, and included what are likely to be the northernmost great horned owl nests on record (up to 68.0113 degrees north). I completed the study during the 2017 and 2018 breeding seasons, during years of high snowshoe hare (Lepus americanus) abundance. The focus of this study was to gain an understanding of how high snowshoe hare abundance influences the recruitment, diet, and distribution of this apex generalist predator, and to determine best methods of detecting great horned owls for similar studies in the future.

  • D1 Toward Urban Climate Resilience in Northeast Asia
    D1 Toward Urban Climate Resilience in Northeast Asia Forum Date: Thursday, 27 June 2019 Language: English (supplemented by Chinese) Time: 11:00 – 12:30 ICLEI contact: Mr. Merlin Lao Rooms: S29-31 Organized by: ICLEI East Asia; UNDRR for Northeast Asia and Global Education and Training Institute (UNDRR ONEA GETI) Target audience: Local government representatives from the People’s Republic of China (PRC), Democratic People’s Republic of Korea (DPRK), Japan, Republic of Korea (ROK) and Mongolia. OBJECTIVE The forum “Accelerating Resilience in Asia: Toward Urban Climate Resilience in Northeast Asia” is a 1.5 hour peer-learning event organized by ICLEI East Asia and UN Office for Disaster Risk Reduction ONEA GETI at the Resilient Cities 2019 Congress to provide local government representatives from Northeast Asia an opportunity to exchange resilience practices in response to mounting climate change impacts and access regional cooperation platforms explicitly for urban resilience. The organizers have ongoing resilience project cooperation with local governments in the region, and this session serves one of the first occasions for them to gather and share actions. In Northeast Asia, even with different political and geographic context, there is a trend that local governments in each country are, mandatorily or voluntarily, formulating action plans, especially on the context of climate change adaptation, emergency response / disaster risk reduction. Participants will be able to listen to cases from local governments directly, and have a deeper understanding on challenges happening in Northeast Asia.

  • Critical Dimensions of Raptors on Electric Utility Poles
    J. Raptor Res. 49(2):210–216 E 2015 The Raptor Research Foundation, Inc. CRITICAL DIMENSIONS OF RAPTORS ON ELECTRIC UTILITY POLES JAMES F. DWYER1 EDM International, Inc., Fort Collins, CO 80525 U.S.A. GAIL E. KRATZ Rocky Mountain Raptor Program, Fort Collins, CO 80524 U.S.A. RICK E. HARNESS EDM International, Inc., Fort Collins, CO 80525 U.S.A. SAMANTHA S. LITTLE Audubon Center for Birds of Prey, Maitland, FL 32751 U.S.A. ABSTRACT.—Avian electrocutions on overhead power structures are a global conservation concern. Size is an important factor influencing whether a bird perched on an electric utility pole is at risk of electrocution, with larger species and larger individuals at greater risk. Ideally, electric poles should protect the largest species (typically Aquila or Haliaeetus species), but protection measures are expensive, making implementa- tion a challenge when a utility’s service area does not include eagles. In these cases, avian protection is sometimes omitted, leaving smaller species at risk because compromise recommendations are unavailable. Flesh-to-flesh distances are a primary determinant of electrocution risk because feathers are only slightly more conductive than air. Metacarpal-to-metacarpal dimensions are particularly important because they quantify the total horizontal distance which can be bridged by the flesh of a bird, but few studies describe metacarpal-to-metacarpal dimensions of at-risk species. Here, we report metacarpal-to-metacarpal and carpal-to-carpal dimensions of 230 raptors of 27 species undergoing rehabilitative care following injury in the wild. Carpal-to-carpal measures facilitate comparison with early efforts by the Avian Power Line Interaction Committee.

United States Department of Agriculture Management Recommendations Forest Service Rocky Mountain for the Northern Goshawk Forest and Range Experiment Station in the Southwestern United States Fort Collins, Colorado 80526 General Technical Report RM-217 Reynolds, Richard T.; Graham, Russell T.; Reiser, M. Hildegard; and others. 1992. Management recommendations for the northern goshawk in the southwestern United States. Gen. Tech. Rep. RM-217, Ft. Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 90 p. Present forest conditions – loss of a herbaceous and shrubby understory, reductions in the amount of older forests, and increased areas of dense tree regeneration – reflect the extent of human influence on these forests. These changes may also be affecting goshawk populations. Information on goshawk nesting habitat and foraging behavior, and the food and habitats of selected goshawk prey, was therefore synthesized to develop a set of management objectives, desired forest conditions, and management recommendations. Key objectives of the guidelines are to provide (1) nesting, post-fledging, and foraging areas for goshawks, and (2) habitat to support abundant populations of 14 primary goshawk prey. Thinning trees in the understory, creating small openings in the forest, and prescribed fires should help produce and maintain the desired forest conditions. Other habitat elements critical for maintaining both goshawk and prey populations include abundant snags and large downed logs, woody debris, interspersion of different tree sizes across the landscape, and the majority of a goshawk’s home range in older-aged forests.
