The Arctic Tern completes annual epic migrations from pole to pole covering at least 40,000 kmon their round-trip journeys. They breed throughout Arctic Alaska from boreal to tundra habitatsand have their highest nesting densities inland (Lensink 1984). Arctic Terns typically choose nestsites on open ground near water and often on small islands in ponds and lakes (Hatch 2002).Arctic terns consume a wide variety of fish and invertebrate prey, fish are particularly importantduring the breeding season for feeding young (Hatch 2002). This species spends their winters(austral summers) in offshore waters near Antarctica (Hatch 2002). Alaskan Arctic Coastal Plainpopulation estimates from 2011 range from 7-12,000 (Larned...
The Pectoral Sandpiper is one of the most abundant breeding birds on the Arctic Coastal Plain ofAlaska. They typically have low nest site fidelity which is likely related to their promiscuousmating strategy, thus nest densities are highly variable from year to year at a given site (Holmesand Pitelka 1998). In Arctic Alaska, primary breeding habitat includes low-lying ponds in a mixof marshy to hummocky tundra and nests are typically placed in slightly raised or better drainedsites (Holmes and Pitelka 1998). Pectoral Sandpipers spend their winters primarily in southernSouth America (Holmes and Pitelka 1998). The current North American population estimate is500,000 and they are believed to be declining (Morrison et...
The Gyrfalcon, the largest falcon, is an iconic bird of the circumpolar arctic and subarctic. Thisspecies nests primarily on precipitous cliff faces and typically utilizes nests built by other species(particularly Common Raven, Golden Eagle, and Rough-legged Hawk) (Booms et al. 2008).Gyrfalcon main prey includes bird species ranging in size from passerines to geese whileptarmigan are the preferred prey. Although not well documented, in winter this species movessouth throughout Canada and sometimes into the northern lower 48. Current population on theNorth Slope (tundrius subspecies) is estimated at 250 breeding pairs (USFWS 2000).
The Red-necked Phalarope commonly breeds in both the Brooks Range foothills and ArcticCoastal Plain of Alaska. In Alaska, this species typically nests in wet tundra near water’s edge.It differs from the Red Phalarope in that it breeds further inland and at higher elevations (Rubegaet al. 2000). Like other phalaropes, this species depends on aquatic food sources for much of itsdiet (Rubega et al. 2000). Red-necked Phalaropes spend winter at sea in tropical waters in largenumbers off the west coast of South America (Rubega et al. 2000). Current North Americanpopulation estimate is 2.5 million with a declining trend (Morrison et al. 2006).
The American Tree Sparrow is a common breeding bird of boreal and tundra dominated habitatsin northern Canada and Alaska. This species breeds in open scrubby areas; willow, birch, andalder thickets, stunted spruce, open tundra with scattered shrubs, often near lakes or bogs(Naugler 1993). In summer American Tree Sparrows consume a wide variety of animal prey(primarily both larval and adult insects). Alaskan birds are short-distance migrants and winter intemperate North America (Naugler 1993). This species’ population is very large (>10 million)although the overall population has undergone a small (statistically insignificant) decrease overthe last 40 years in North America (Butcher and Niven 2007).
The Long-billed Dowitcher is a medium-sized shorebird that commonly breeds on the ArcticCoastal Plain of Alaska. This species nests in higher densities in the western portion of thecoastal plain compared to the east (Johnson et al. 2007). They prefer wet grassy meadows fornesting often showing an affinity for sedge-willow, wet meadow or sedge marsh along drainagesor near ponds (Takekawa and Warnock 2000). Long-billed Dowitchers generally migrate west ofthe Mississippi River and winter primarily along the Pacific and Gulf Coasts of North Americainto Mexico (Takekawa and Warnock 2000). Current population estimate of the North Americanpopulation is 400,000 (Morrison et al. 2006).
The White-rumped Sandpiper is a small shorebird that is a relatively rare breeder in ArcticAlaska. They nest in coastal wetlands between Barrow and Cape Halkett on the Arctic CoastalPlain of Alaska
The Western Sandpiper is one of the most abundant sandpipers in the western hemisphere. InAlaska, the core of its breeding population is in the Yukon-Kuskokwim River Delta. It alsobreeds less commonly in the western portion of the North Slope (Johnson et al. 2007). Thisspecies nests in well-drained moist to upland tundra habitats dominated by dwarf shrubs andtussock grasses (Wilson 1994).
In Alaska, changes in snow, ice, and weather, have resulted in risks to human lives, infrastructure damage, threats to valuable natural resources, and disruption of hunting, fishing, and livelihoods.Leaders from the Aleutians to the Chukchi Sea came together for a series of Coastal Resilience and Adaptation Workshops, spearheaded by three Landscape Conservation Cooperatives and the Aleutian Pribilof Islands Association. Tribal leaders, resource managers, community planners, and scientists explored strategies to adapt to these unprecedented changes.The workshop series brought together 14 Organizing Partners 34 Tribes, 15 State & Federal Agencies, and a total of more than 200 participants to meet in four regional...
LCC funding allowed completion of this BLM initiative to develop a North Slope-wide cover type map and create a crosswalk that integrates all component cover type maps that comprise the larger overall North Slope cover type map.This map is the outcome of a multi-year project to produce a moderate resolution landcover base map for the North Slope of Alaska to serve as a primary base layer for long-term science and planning activities on the North Slope. New Landsat Thematic Mapper (TM) 30 meter resolution landcover maps were produced for the far western arctic, and for the area between the National Petroleum Reserve - Alaska (NPRA) and Arctic National Wildlife Refuge. In the NPRA, an existing land cover map from...
This polygon feature class represent areas surveyed for yellow-billed loons (Gavia adamsii) and is one component of the Yellow-billed Loon Geodatabase. This database is intended to be a qualitative “first look” at where yellow-billed loons have been recorded and where surveys have been conducted. This spatial dataset is intended for general planning and mapping purposes rather than for deriving density estimates. The geodatabase is comprised of two feature classes (observations and survey_poly) and two tables (incidental_attributes and reference_information)
The Bureau of Land Management- Arctic Field Office has a requirement for coordinating research andmonitoring projects related to the effectiveness of stipulations and surface resource impacts in theNational Petroleum Reserve - Alaska. Yellow-billed Loons are among the least common breeding birdsin the mainland United States and the U.S. breeding population is concentrated largely within theNational Petroleum Reserve – Alaska (NPR-A). Interest in developing the oil and gas reserves withinNPR-A has increased within the last 10 years, along with a need for better information with which toprotect loon populations. Fundamental to protection strategies is a good understanding of distributionand abundance.
The Alaska ShoreZone program has been able to document Arctic coastal biologyand dynamic processes through high resolution aerial imagery, videography, andground assessments: a snapshot in time of the ever changing Arctic coast. Some ofthe most spectacular of these images have been collected in this volume, CoastalImpressions: A Photographic Journey along Alaska’s Arctic Coast. Glance throughthese pages, study and ponder over them , then close your eyes and imagine.Wipe away your preconceived notions of the Arctic and learn about the gem thatis the true Arctic coast.
This dataset contains rasters that represent mapped habitat suitability indices for 8 shorebird species, a raster that represents mean habitat suitability indices for all 8 species, and a raster that represents the number of species in which the habitat suitability index exceeded the selected threshold value for each pixel. The shorebird species used for this modeling effort are American Golden-Plover [AMGP], Black-bellied Plover [BBPL], Dunlin [DUNL], Long-billed Dowitcher [LBDO], Pectoral Sandpiper [PESA], Red Phalarope [REPH], Red-necked Phalarope [RNPH], and Semipalmated Sandpiper [SESA].

The Spectacled Eider is a medium-sized sea duck with males easily recognized by their striking“clown-like” head plumage. This species was listed as threatened in 1993 under the EndangeredSpecies Act as it has suffered severe population declines in western Alaska. The Arctic CoastalPlain population may also be declining. In Arctic Alaska, breeding Spectacled Eiders use riverdeltas and wet tundra habitats, including drained-lake basins, flooded wetlands, and islets withina matrix of thaw lakes for both nesting and foraging (Petersen et al. 2000). During the breedingseason, their diet consists primarily of both adult and larval aquatic insects (Petersen et al. 2000).Alaskan breeders spend their winters offshore in...
More information is needed about species composition, abundance, or distribution of the microfauna and meiofauna living within the interstitial spaces of the littoral zones along the Beaufort Sea coast. Shorebirds depend on meiofauna for food for pre-migratory fattening and these organisms make important contributions to bioremediation of oil spills.The information obtained from this jointly-funded research can contribute to development of mitigation measures and strategies to reduce potential impacts from post-lease exploration and development. This information need extends to the lower trophic levels forming the base of these complex food webs and the biochemistry that influences these relationships. Their contributions...

Using a bioclimatic envelope approach, University of Alberta investigators project how the distribution and abundance of boreal forest birds across North America will respond to different scenarios of future climate-change. Investigation emphasis is on mapping and quantifying potential range expansions of boreal bird species into Arctic and subarctic regions across Alaska and Canada. The final products demonstrate a broad continental-scale overview of potential shifts in avian distribution.
Many Arctic shorebird populations are declining, and quantifying adult survival and the effects of anthropogenic factorsis a crucial step toward a better understanding of population dynamics. We used a recently developed, spatially explicitCormack–Jolly–Seber model in a Bayesian framework to obtain broad-scale estimates of true annual survival rates for 6species of shorebirds at 9 breeding sites across the North American Arctic in 2010–2014. We tested for effects ofenvironmental and ecological variables, study site, nest fate, and sex on annual survival rates of each species in thespatially explicit framework, which allowed us to distinguish between effects of variables on site fidelity versus truesurvival. Our...

Arctic wetlands, where millions of local and migratory birds nest, are composed of a mosaic of ice wedge polygons, non-patterned tundra, and large vegetated drained thaw lake basins. Regional climate projections suggest that evapotranspiration, rainfall, and snowfall will increase, making it difficult to predict how surface water distribution might change and how habitats for the invertebrate resources used by waterbirds will be impacted. This study will focus on evaluating how climate change will affect the invertebrate community, and whether the change in climate (through changes in hydrology and surface energy balance) could induce a trophic mismatch that might alter the growth and survival of shorebird young....
