This collection of files includes audio files downloaded directly from acoustic monitors in 2022, providing sound recordings of shorebird PRISM plots. Using automatic recorders allows for a consistent, unbiased, and regular data collection during the whole summer and will be used to verify PRISM survey data and determine if shorebirds can be monitored remotely using audiorecording devicies. Files are organized in folders by plot. These data do not represent all locations within the Arctic National Wildlife Refuge where specific avian species may be present, as surveys only occurred in discrete survey plots. Additionally, individual birds may have went undetected within survey plots, as detectability was likely less...

This file provides data pertaining to occurrence (i.e., presence) of all bird species encountered during rapid surveys. Each record pertains to a unique species observed on a given plot. Therefore, survey plots may have more than one record when more than one species was observed on a given plot. Each species is listed only once per plot and includes species seen or heard both inside and outside (usually within 200 to 300 meters) plot boundaries (including species counted during PRISM surveys - see ‘ANWR PRISM rapid survey data’ and during nest survival surveys - see ‘file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_003_ANWR_nest_survival’). These data do not represent all locations within the Arctic National Wildlife...

This file provides data collected during rapid surveys of both rapid and intensive plots, with each record pertaining to a unique sighting of a given shorebird species within a survey plot including information on species, number of individuals, and breeding status. Therefore, each survey plot may have multiple records when more than one sighting occurred. Each record also contains information pertaining to the survey plot including date and time of survey, survey conditions, survey location, and ecological and biological conditions of the survey plot.A portion of these data are available on ServCat (https://ecos.fws.gov/ServCat/Reference/Profile/57583).Much of these data have been published in Lyons, J.E., S.C....

This file contains information on resightings of shorebird tagged in 2017 that were not recaptured to retrieve tagging device. Information included in the file includes date and time of resighting, location, and band combination.The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain. It is strongly recommended that careful attention be paid to the contents of the metadata file associated with these data to evaluate data set limitations, restrictions, or intended use. The originators of this dataset shall not be held liable for improper or incorrect use of the data described and/or contained herein.Potential users of these data should first contact the data...

This file contains information on feather samples contained within the inventory including information on sample type, sample location, and associated banding information.These samples are maintained by USFWS and the feather samples in particular are part of the AviSample Network metadata repository (see Brlik et al. 2022. The reuse of avian samples: opportunities, pitfalls, and a solution. Ibis 164:343-349).Additional information for samples collected at Utqiagvik and in association with the tracking project can be found in the Utqiagvik shorebird project (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_009_Utqiagvik_shorebird_project) and shorebird tracking study archives (file://ifw7ro-file.fws.doi.net/datamgt/mbm/mbmsh_008_Shorebird_tracking),...

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...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...
