Tracking Data for Tundra Swans (Cygnus columbianus)
Available here are tracking data of Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of habitats in breeding, wintering, and migratory areas of North America.
USGS Alaska Science Center Wildlife Tracking Data Collection
Understanding the short- and long-distance movements of wildlife is critical for a wide variety of ecological research questions and management decisions. Since the mid-1980s, the USGS Alaska Science Center has used information from telemetry devices on wildlife species to determine locations of animals throughout their annual cycles, understand patterns of habitat use, quantify time spent on...
Tracking Data for Marbled Godwits (Limosa fedoa)
Available here are tracking data of Marbled Godwits, a large-bodied shorebird that, in Alaska, nests in the southwestern portion of the state. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of different coastal areas in the Pacific region.
Shorebird Research
With its vast size and geographic position at one end of numerous migration pathways, Alaska is a critically important site for the world’s shorebirds. Thirty-seven shorebird species regularly breed in Alaska. Most of these species conduct epically long migrations to take advantage of abundant food resources, making Alaska a global resource for shorebirds. Shorebird research at the USGS Alaska...

These are raw field data from a stratified random survey to inventory the birds breeding in lowlands (elevation below 100m) of the Alaska Peninsula, during summers 2004-2007. Data were collected at 792 survey points on 52 5-km x 5-km plots. The data are in: 1) four PDF files of digitally scanned original field data forms describing each of the 52 plots, and 2) a ZIP package containing 2824...
Migratory Timing and Site Use of Marbled Godwits Breeding in Alaska, 2008–2015
This dataset contains migration timing and land-based location information from nine Marbled Godwits (Limosa fedoa beringiae) equipped with solar-powered satellite transmitters on breeding grounds near Ugashik, Alaska, in June of 2008. Transmitters were programmed with a duty cycle of 10 hr on and 48 hr off, yielding 10,858 locations (47-3,490 locations per bird, depending on th
Bristle-thighed Curlew Capture Data from James Campbell National Wildlife Refuge, O'ahu, Hawaii, 2012-2014
This data set contains banding, morphology, and satellite telemetry information for Bristle-thighed curlews (Numenius tahitiensis) that were captured between 2012 and 2014 on the James Campbell National Wildlife Refuge on the island of O'ahu, Hawaii (21.68 N, -157.95 W).
After-hatch and hatch year Buff-breasted Sandpipers (Calidris subruficollis) can be sexed accurately using morphometric measures
Determining the sex of birds quickly in the field can help in studies of behavior and distribution, and when selecting particular sexes for deploying tracking devices or collecting samples. However, discerning males from females is difficult in species that are plumage monomorphic and have overlapping sexual-size dimorphism, as in Buff-breasted...
Almeida, Juliana B.; Lopes, Iara F.; Oring, Lewis; Tibbitts, Lee; Pajot, Lisa M.; Lanctot, Richard B. A red knot as a black swan: How a single bird shows navigational abilities during repeat crossings of the Greenland Icecap
Despite the wealth of studies on seasonal movements of birds between southern nonbreeding locations and High Arctic breeding locations, the key mechanisms of navigation during these migrations remain elusive. A flight along the shortest possible route between pairs of points on a sphere (‘orthodrome’) requires a bird to be able to assess its...
Kok, Eva; Tibbitts, Lee; Douglas, David C.; Howey, Paul; Dekinga, Anne; Gnep, Benjamin; Piersma, Theunis Through thick and thin: Sexing Bristle-thighed Curlews Numenius tahitiensis using measures of bill depth
Birds often exhibit diagnostic traits that differ among individuals of the same species with regard to factors like sex, age, or breeding status. Shorebirds exhibit a wide diversity of colors, shapes, and sizes of their bills, and these traits are commonly used to determine the sex of individuals. In curlews (genus Numenius), length alone...
Ruthrauff, Daniel R.; Handel, Colleen M.; Tibbitts, Lee; Gill, Robert E. Tracking the migration of Pacific Golden-Plovers from nonbreeding grounds at Moorea, French Polynesia, using Pinpoint GPS-Argos tags
We used Pinpoint GPS-Argos tags to track migration of Pacific Golden-Plovers Pluvialis fulva in 2017 and 2018 from Moorea Island, at the extreme southeastern edge of the species’ winter range. Of 20 tagged birds, 13 uploaded locations during all or part of their northward migration. The birds departed in mid-April traveling a long (8,250...

Suitable habitat for Arctic-breeding migratory shorebirds is decreasing at their traditional wintering islands and atolls in the Central Pacific Flyway (i.e., Oceania) due to habitat degradation, reclamation, and sea-level rise. To maintain the size and resiliency of their populations, migratory shorebirds will need to expand their winter ranges...
Tibbitts, Lee; Ruthrauff, Daniel R.; Underwood, Jared G.; Patil, Vijay P. Filling knowledge gaps in a threatened shorebird flyway through satellite tracking
Satellite‐based technologies that track individual animal movements enable the mapping of their spatial and temporal patterns of occurrence. This is particularly useful in poorly studied or remote regions where there is a need for the rapid gathering of relevant ecological knowledge to inform management actions. One such region is East Asia, where...

Limited data on harvest and population parameters are major impediments to assess shorebird harvest sustainability. Because of sharp declines in shorebird populations, timely conservation efforts require approaches that account for uncertainty in harvest sustainability. We combined harvest assessment and ethnographic research to better understand...
Naves. Liliana; Keating, Jacqueline; Tibbitts, Lee; Ruthrauff, Daniel R. Satellite tracking of gulls and genomic characterization of fecal bacteria reveals environmentally mediated acquisition and dispersal of antimicrobial resistant Escherichia coli on the Kenai Peninsula, Alaska
Gulls (Larus spp.) have frequently been reported to carry Escherichia coli exhibiting antimicrobial resistance (AMR E. coli); however, the pathways governing the acquisition and dispersal of such bacteria are not well-described. We equipped 17 landfill-foraging gulls with satellite transmitters and collected gull fecal samples longitudinally from...

The study of avian movement has detailed a spectrum of strategies for the timing and use of sites throughout the annual cycle, from near randomness to complete consistency. New tracking devices now permit the repeated tracking of individual animals throughout the annual cycle, detailing previously unappreciated levels of variation within migratory...
Ruthrauff, Daniel R.; Tibbitts, Lee; Gill, Robert E. Survival of Bristle-thighed Curlews equipped with externally mounted transmitters
Telemetry devices are widely used in avian research, but the degree to which the deployment of such devices affects the survival of study subjects is often not addressed. It is generally assumed that such effects are less pronounced in large-bodied species that conduct relatively short migrations and carry relatively light telemetry devices. We...
Ruthrauff, Daniel R.; Tibbitts, Lee; Patil, Vijay P. Inventory of lowland-breeding birds on the Alaska Peninsula
We conducted the first systematic inventory of birds in the lowlands (areas ≤100 m above sea level) of the Alaska Peninsula during summers of 2004–2007 to determine their breeding distributions and habitat associations in this remote region. Using a stratified random survey design, we allocated sample plots by elevation and land cover with a...
Savage, Susan E.; Tibbitts, Lee; Sesser, Kristin; Kaler, Robb S.A. Fuelling conditions at staging sites can mitigate Arctic warming effects in a migratory bird
Under climate warming, migratory birds should align reproduction dates with advancing plant and arthropod phenology. To arrive on the breeding grounds earlier, migrants may speed up spring migration by curtailing the time spent en route, possibly at the cost of decreased survival rates. Based on a decades-long series of observations along an...
