Tracking Data for Long-tailed Ducks (Clangula hyemalis)
Available here are tracking data of long-tailed duck, a species of seaduck that breeds throughout the circumpolar Arctic and spends the winter in coastal areas of northern and mid latitudes. These data were collected to determine range-wide migratory routes, migratory timing, and stopover habitats of this species.
Tracking Data for Black Scoters (Melanitta americana)
Available here are tracking data of Black Scoter, a duck species that breeds throughout higher latitudes of Alaska and Canada and winters along coastal areas of North America. These data were collected to better understand the timing and patterns of migratory movements between breeding and wintering areas.
Avian Influenza Research
Since 2006, the USGS Alaska Science Center has been part of the State and Federal interagency team for the detection and response to highly pathogenic (HPAI) viruses in North America. Avian influenza or "bird flu" is a viral disease that primarily infects domestic poultry and wild birds. Avian influenza viruses are naturally occurring in wild birds such as ducks, geese, swans, and gulls. These...
Goose Research
The USGS Alaska Science Center has had a focus on addressing science questions related to geese in Alaska for decades. Information on these species is critical because all are important resources for subsistence and sport hunters in the state and outside of Alaska where these birds spend the winter. The large majority of goose populations in Alaska breed on national wildlife refuges (managed by...
Dabbling and Diving Duck Research
Dabbling and diving ducks, such as mallards, pintails and scaup, are widespread species throughout North America. Additionally, their migratory flyways pass through Asia and North America overlap in Alaska. Population trends of these species are closely tracked through aerial surveys by management agencies. Results from these and other surveys are then used to formulate management actions to...

Capture Data from Molting Steller's Eiders (Polysticta stelleri) at Izembek and Nelson Lagoons, Alaska Capture Data from Molting Steller's Eiders (Polysticta stelleri) at Izembek and Nelson Lagoons, Alaska
These data are in one table and contain information on the location, age, sex, and measurements (mass, ninth primary, culmen, and total tarsus) of Steller's Eiders during the flightless molt period. Captures took place at Izembek and Nelson Lagoons on the north side of the Alaska Peninsula.
Movement Data for Migrating Geese Over the Northeast Pacific Ocean, 2018-2021 Movement Data for Migrating Geese Over the Northeast Pacific Ocean, 2018-2021
This dataset consists of one table with a record (row) for each goose location and columns containing location information and covariates. The dataset was used in an analysis of altitude selection and flight propensity in an accompanying paper (Weiser et al. 2024) and is being provided here to allow replication of that analysis. Goose locations (latitude, longitude, and altitude) were...
Data from Sampling for Small-Scale Geographic Variation in Salinity Along the Lower Kashunuk River, Yukon-Kuskokwim Delta, Alaska, 1993 Data from Sampling for Small-Scale Geographic Variation in Salinity Along the Lower Kashunuk River, Yukon-Kuskokwim Delta, Alaska, 1993
This dataset provides salinity measurements collected from water bodies along 17 east-west transects in along the lower Kashunuk River, Yukon-Kuskokwim Delta National Wildlife Refuge, 25 June - 30 July 1993.
Waterfowl Lead Exposure Data in Alaska and Russia, 1993-2022 Waterfowl Lead Exposure Data in Alaska and Russia, 1993-2022
This dataset identifies lead (Pb) concentration found in the blood of waterfowl sampled in western and northern Alaska and eastern Russia between 1993 and 2022. Data include age, sex, body measurement, capture location, presence or absence of lead shot on x-rays, and blood lead levels. Because the study took place over a number of years at the same study sites, many of the same birds...

Trace element data in whole blood collected in 2001 from Steller's eiders (Polysticta stelleri; STEI) at Izembek Lagoon and Steller's eiders, harlequin ducks (Histrionicus histrionicus; HADU), black scoters (Melanitta americana; BLSC), and a long-tailed duck (Clangula hyemalis; LTDU) at Dutch Harbor, Alaska. Data include species, location, age, sex, percent moisture of blood sample, and...

Geese migrating over the Pacific Ocean select altitudes coinciding with offshore wind turbine blades Geese migrating over the Pacific Ocean select altitudes coinciding with offshore wind turbine blades
Renewable energy facilities are a key part of mitigating climate change, but can pose threats to wild birds and bats, most often through collisions with infrastructure. Understanding collision risk and the factors affecting it can help minimize impacts on wild populations. For wind turbines, flight altitude is a major factor influencing collision risk, and altitude-selection analyses can...

Evaluating conservation units using network analysis: A sea duck case study Evaluating conservation units using network analysis: A sea duck case study
Conserving migratory wildlife requires understanding how groups of individuals interact across seasons and landscapes. Telemetry reveals individual movements at large spatiotemporal scales; however, using movement data to define conservation units requires scaling up from individual movements to species- and community-level patterns. We developed a framework to define flyways and...

Evaluation of breeding distribution and chronology of North American scoters Evaluation of breeding distribution and chronology of North American scoters
North America's scoter species are poorly monitored relative to other waterfowl. Black Melanitta americana, surf M. perspicillata, and white-winged M. deglandi scoter abundance and trend estimates are thus uncertain in many parts of these species' ranges. The most extensive source of waterfowl abundance and distribution data in North America is the Waterfowl breeding population and...

Status of spectacled eiders (Somateria fischeri) on the Yukon-Kuskokwim Delta, Alaska, 2022—Testing and updating predictive models Status of spectacled eiders (Somateria fischeri) on the Yukon-Kuskokwim Delta, Alaska, 2022—Testing and updating predictive models
The nesting biology and demography of spectacled eiders (Somateria fischeri) along the lower Kashunuk River on the Yukon-Kuskokwim Delta, Alaska, were studied from 1993 to 2002. This previous work demonstrated that the breeding population on the study area was declining, and demographic modeling predicted that the population would continue to decline from 2002 forward. The predicted...

Climate change and coastal wetland salinization: Physiological and ecological consequences for Arctic waterfowl Climate change and coastal wetland salinization: Physiological and ecological consequences for Arctic waterfowl
Coastal wetland salinization related to warming climate has the potential to impact ecological systems globally. In Alaska, the Yukon-Kuskokwim Delta (YKD) supports large concentrations of breeding water birds and is an ecologically important area for conservation of migratory bird biodiversity. On the YKD, the majority of waterfowl nest in low elevation coastal tundra where storm surges...
