Shorebirds are a group of predominantly migratory birds that are declining at an alarming rate; many of them have declined by more than 50% since 1970 and 13 are of federal conservation concern. With staggeringly long, trans-hemispheric migrations along each of North America’s migratory flyways — distinct corridors that divide North America longitudinally — shorebirds breeding in the Arctic and sub-Arctic and wintering in Central and South America encounter a multitude of threats during their annual cycles. This study aims to track the fall migration of a suite of species from their breeding sites across Alaska to the southern extent of their respective ranges and address how differences in migratory connectivity...

Multiple lines of evidence suggest that the Gray-headed Chickadee (Poecile cinctus lathami), a population endemic to Alaska and northwestern Canada, has declined and/or been extirpated from locations where they were considered historically common. In contrast, the Boreal Chickadee, a native congener, has recently colonized locations where Gray-headed Chickadees once occurred. This project focuses on whether hybridization (and subsequent transfer of genetic material from one species into another with continued breeding events overtime) between these two closely related chickadee species may be responsible for Gray-headed Chickadee declines. Specifically, our objectives are to: 1) Conduct call-playback surveys to...

Eareckson Air Station (AS) on Shemya Island is strategically located on the far eastern end of Alaska’s Aleutian archipelago. The frequent use of aircraft at this installation poses unique conflicts between the natural resources of the island and maintaining mission readiness and human/aircraft safety. Sikes Act Section 101(a) (16 U.S. Code 670a(a)) requires that Department of Defense (DoD) installations prepare Integrated Natural Resources Management Plans (INRMP) to conserve and rehabilitate natural resources on military installations and ensure that activities on the installations are integrated and consistent with environmental stewardship, laws and regulations, and the military mission. Accordingly, the DoD...

This file contains the transect end points used in the 2019 distance sampling pilot. These are produced by the R code found in Rmarkdown file ‘plotCenters.Rmd’. Transect end points are written to a csv file for input in field GPS units to guide field staff during surveys. Geographic coordinates are in epsg:4269.
