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...

Many North American shorebird species are experiencing significant population declines, but we have incomplete information about the population sizes and trends for most species. Conservation efforts are underway throughout the Hemisphere to reverse these declines, but we cannot measure the success of those efforts until we have an accurate assessment of population sizes and trends. The Program for Regional and International Shorebird Monitoring (PRISM) is a broad-scale, multi-national effort to monitor both the sizes and trends of shorebird populations (https://www.shorebirdplan.org/science/program-for-regional-and-international-shorebird-monitoring/). PRISM also strives to describe the distribution and habitat...

We have gathered information on all known recaptures and resightings of marked Dunlin throughout the East-Asian Australasian flyway, as well as opportunistically at other locations. The objectives of this study were to (1) identify regional connectivity patterns within and among subspecies of Dunlin migrating and wintering along the EAAF, (2) examine the regional connectivity patterns of Dunlin of unknown subspecies captured and marked at sites on the nonbreeding grounds, (3) examine recovery patterns of arcticola Dunlin initially captured on the NW and NE portions of their Alaska breeding range, (4) examine recovery patterns of arcticola males and females, (5) examine recovery patterns of arcticola Dunlin of different...

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...

In 2008 and 2009, we investigated the survival of chicks from initial and experimentally-induced replacement nests of arcticola Dunlin (Calidris alpina) breeding near Utqiaġvik, Alaska. We monitored survival of 66 broods from 41 initial and 25 replacement nests. See Saalfeld, S.T., B.L. Hill, C.M. Hunter, C.J. Frost, and R.B. Lanctot. 2021. Warming Arctic summers unlikely to increase productivity of shorebirds through renesting. Nature Scientific Reports 11-15277 for more detailed methods and data analysis.Information for the Dunlin brood survival project were obtained concurrently with information obtained for the Utqiagvik shorebird project and information on chicks and nests included in these files may also be...

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....

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...

Reproductive success is a key demographic parameter that can have profound impacts on a species’ population trend; however, broad-scale nest survival data are unavailable for all Arctic-breeding shorebird species. Accordingly, we set out to 1) measure current nest survival rates across a large area of the Arctic National Wildlife Refuge, and 2) identify predators of nests, so as to help elucidate the potential role reproductive failure plays in current shorebird population declines. This information is also relevant for assessing the indirect effects of land management decisions such as oil and gas development on a species’ reproductive success. In 2019 and 2022, we monitored 129 shorebird nests of 9 species using...
