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...
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 Scoter (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.
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...

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 evaluate

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 identify importan

Evaluation of breeding distribution and chronology of North American scoters
North America's scoter species are poorly monitored relative to other waterfowl.

Optimizing surveys of fall-staging geese using aerial imagery and automated counting
Ocular aerial surveys allow efficient coverage of large areas and can be used to monitor abundance and distribution of wild populations. However, uncertainty around resulting population estimates can be large due to difficulty in visually identifying and counting animals from aircraft, as well as logistical challenges in estimating detection probabilities. Photographic aerial surveys can mitigate

The abundance of greater white-fronted geese (Anser albifrons frontalis) on the Arctic Coastal Plain (ACP) of northern Alaska, USA, has more than tripled since the late 1990s; however, recent rate of annual population growth has declined as population size increased, which may indicate white-fronted geese on the ACP are approaching carrying capacity.
