Shorebirds are among the most rapidly declining species in North America (Rosenberg et al. 2019), with many long-distance migrants experiencing the greatest declines (Environment Canada 2020). Nonetheless, not all shorebirds are declining and there may be differences among species and populations using different migratory routes. For instance, previous meta-analyses have suggested that shorebirds using the Mid-Continental Flyway are experiencing more rapid declines than those using the Pacific or Atlantic flyways (Thomas et al. 2006). At the same time, within a species, more northerly breeding populations are experiencing greater phenological mismatches and lower reproductive success than southerly ones (Kwon et...

The Yukon-Kuskokwim Delta (YKD) Aerial Breeding Pair Survey provides data on the spring abundance of targeted waterfowl species nesting on the YKD coastal zone in western Alaska. This region supports millions of waterbirds that comprise one of the largest and most important waterfowl breeding grounds in North America, including species of concern such as the red-throated loon (Gavia stellata), emperor goose (Chen canagica), Pacific black brant (Branta bernicla nigricans), common eider (Somateria mollissima), black scoter (Melanitta nigra), long-tailed duck (Clangula hyemalis), and the threatened spectacled eider (Somateria fischeri). The YKD goose, swan, and crane survey was first implemented in 1985 to monitor...

The primary objective of this project was to monitor the growth of shorebird chicks by recapturing them from hatch to fledgling in relation to food abundance and weather conditions. In 2014 and 2015, we attempted to estimate the impacts of trophic mismatch by experimentally creating late hatched broods by refrigerating eggs to delay hatch. Transmitters were then attached to adults and chicks to follow and recapture chick in order to estimate growth rates and survival (see annual protocol documents for further information).Information for the Utqiagvik chick monitoring study were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these...

This project aims to estimate spatial and temporal trends of waterfowl and waterbirds on the Arctic Coastal Plain (ACP) of Alaska from 2007 to present. The main approach is motivated by Amundson et al. (2019) using space-time generalized additive models (GAMs, Wood 2017) but with some improvements to handle observer effects and to associate sampling effort to specific spatial locations along a sampled transect similar to Miller et al. (2013). As part of this effort, a major data quality control process was begun in March 2022 that led to the correction of many data errors and re-formatting of the original 2007 to 2023 data to make it more accessible and usable to outside partners (original raw data available here)....

In 2019 a pilot study was conducted to determine the feasibility of using distance sampling to estimate density and population size of goose and eider nests on the Yukon-Kuskokwim Delta (YKD). Distance sampling (Buckland et al. 2001) is a common and well-understood method to estimate wildlife population size or density, especially for sparse and hard-to-detect populations. A main advantage of distance sampling is that it accounts for imperfect detection and gives precise estimates for a given level of effort relative to other methods. The objectives for the pilot project in 2019 was to (1) determine if distance sampling is feasible on the YKD, (2) determine what aspects of the field protocol need to be changed or...

Upland Sandpiper is one of many declining shorebird species (-4.6%/year in Alaska; Ziolkowski et al. 2023) which breed on military and adjacent lands in Alaska. Western and eastern populations are small and unstable, and the species is endangered at the state level in several eastern U.S. states (Houston et al. 2023). Though there has been considerable work with Upland Sandpipers in their core, central U.S. breeding areas, this is the first dedicated study of Upland Sandpipers in Alaska. The objectives are to resight, band, and track Upland Sandpiper at breeding sites in Delta Junction, AK and Donnelly Training Area (TA 501 & TA 511) to estimate vial rates, determine migratory connectivity, and determine important...

Beginning in 2003, we have conducted a long-term shorebird breeding ecology study at Utqiaġvik (formerly Barrow), Alaska. The objectives of this study are to (1) collect baseline data on temporal and spatial variability of shorebird diversity and abundance, (2) collect information on nest initiation and effort, replacement clutch laying, clutch and egg size, nest and chick survival, and other demographic traits of Arctic-breeding shorebirds, (3) establish a marked population of as many shorebird species as possible that will allow us to estimate adult survival, mate and site fidelity, and natal philopatry, and (4) relate weather, food availability, and predator and prey abundances to shorebird productivity and survival....
Information on abundance, distribution, chronology, and habitat associations of birds at U.S. Air Force Long Range Radar Sites (USAF LRRS) and U.S. Navy lands is either outdated or lacking. In other situations, existing information has been obtained using a variety of incompatible methods thereby complicating the ability to discern changes to bird communities or the habitats they rely upon. Up-to-date information on the use of military lands by all bird species is important for both the Department of Defense (DOD) and the U.S. Fish and Wildlife Service (USFWS). Furthermore, updating avian inventories and implementing a standardized monitoring program across military lands helps USFWS-MBM by improving avian trend...

These datasets describe the inventory of feather and blood samples collected from shorebirds that were captured primarily in northern Alaska but also in other parts of the world where studies were conducted on migratory species that breed in Alaska. 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)...

The degradation of critical wintering and migratory stop-over sites is known to have direct consequences on the survival and reproductive condition of migratory shorebirds. However, little is known about migratory movements and connectivity of shorebird populations. By identifying migratory stop-over and wintering areas, we can begin to identify sites that should be conserved and evaluate the relative risks of development and climate change scenarios. Beginning in 2017, we initiated a project to track the migration movements of shorebird species using Argos, GPS, and Pinpoint tags. The primary objective of this study is to collect baseline information on movement patterns of shorebirds during the post-breeding period...

The Spoon-billed Sandpiper (Eurynorhynchus pygmeus) is a critically endangered species (Bird Life International 2011) with a population estimated at 661-678 individuals (but only 210-228 breeding pairs, Clark et al. 2016). Although it principally breeds in Russia and has not officially been documented breeding in Alaska, observations of Spoon-billed Sandpipers have been recorded in Alaska during the breeding season (Kessel and Gibson 1978), and a recently developed habitat suitability model indicated that suitable nesting habitat occurs in Alaska’s Chukchi Sea region (RSBP 2012). However, no systematic survey of potential breeding habitat had been conducted in this region during the spring and summer when this species...

Feathers have been collected from shorebirds from 2006-2019 across Alaska and Canada. To determine the impact of feather pulling on subsequent feather growth, we identified and scanned feathers that were collected in subsequent years. In this case, we restricted our dataset to samples in which the same feathers were pulled in subsequent years and for those collected only after their initial pulling (i.e., year x and x+1). These scans will then be used to look at size and shape in comparison to original feathers to determine if pulling of feathers has any impact on growth of feathers in the following year.The data providers have invested considerable effort in QA/QC, but it is possible that undetected errors remain....

Principal to the management of migratory landbird resources is an understanding of their occurrence within the landscape. Baseline information on bird distribution is a primary need “to preserve a natural diversity and abundance of fauna and flora on refuge lands” (U.S. Fish and Wildlife Service [USFWS] 1993a). Documenting the occurrence and distribution of all migratory bird species is a priority of the USFWS’s action plan for developing a nongame bird inventory and monitoring strategy for National Wildlife Refuge system lands (USFWS 1993b ). Distribution and abundance information previously collected on National Wildlife Refuges has contributed to the description of distributional patterns of birds in Alaska....

The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...

Indirect interactions between different prey species modulated by shared predators (e.g. Arctic fox) are believed to have important impacts on the structure and/or dynamics of some communities. Yet, our understanding of these types of interactions are still fragmentary. To fill this information gap, the joint circumpolar project on indirect trophic interactions was established in 2016. This project built upon ongoing projects exploring related questions in Canada (Marie-Andrée Giroux, Nicolas Lecomte, Joel Bety) and Greenland (Olivier Gilg, Niels M. Schmidt), while taking advantage of existing networks (ASDN in North America and “Interactions” program in Greenland and Eurasia). The aim of this project was to promote...

Coastal wetlands purify water, protect coastal communities from storms, sequester (store) carbon, and provide habitat for fish and wildlife. They are also vulnerable to climate change. In particular, changes in winter climate (warmer temperatures and fewer freeze events) may transform coastal wetlands in the northern Gulf of Mexico, as mangrove forests are expected to expand their range and replace salt marshes. The objective of this research was to evaluate the ecological implications of mangrove forest migration and salt marsh displacement. As part of this project, researchers identified important thresholds for ecosystem changes and highlighted coastal areas in the southeastern U.S. (e.g., Texas, Louisiana,...

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...
