Waterfowl Research

Active
By Alaska Science Center September 29, 2025

Scientists at the USGS Alaska Science Center have conducted research on waterfowl species (ducks, geese, and swans) in Alaska since the 1970s. Because Alaska is an international crossroads of migratory bird flyways, with millions of birds from Asia and North America breeding in Alaska each summer, USGS research has also taken place in adjacent countries (Russia, Japan, Canada, Mexico) and in the lower 48-states and Hawaii.

The main objectives of the USGS Alaska Science Center waterfowl research program are to:

  • Identify and fill gaps in our knowledge about the ecology of waterfowl species in Alaska
  • Quantify the drivers of population trends of waterfowl populations in Alaska and throughout their annual cycle
  • Provide science information to Department of Interior management agencies and others for decision making regarding waterfowl disease, population delineation, and species of conservation concern

Stochastic variation in avian survival rates: Life-history predictions, population consequences, and the potential responses to human perturbations and climate change Stochastic variation in avian survival rates: Life-history predictions, population consequences, and the potential responses to human perturbations and climate change

Stochastic variation in survival rates is expected to decrease long-term population growth rates. This expectation influences both life-history theory and the conservation of species. From this expectation, Pfister (1998) developed the important life-history prediction that natural selection will have minimized variability in those elements of the annual life cycle (such as adult...

Spring migration routes and chronology of surf scoters (Melanitta perspicillata): A synthesis of Pacific coast studies Spring migration routes and chronology of surf scoters (Melanitta perspicillata): A synthesis of Pacific coast studies

Understanding interconnectivity among wintering, stopover, and breeding areas of migratory birds is pivotal to discerning how events occurring in each might have a cross-seasonal effect on another. Such information can guide the location and timing of conservation efforts. Thus, we examined spring migration routes, chronology, and stopover use of 85 surf scoters (Melanitta perspicillata...

Change in abundance of Pacific brant wintering in Alaska: Evidence of a climate warming effect? Change in abundance of Pacific brant wintering in Alaska: Evidence of a climate warming effect?

Winter distribution of Pacific Flyway brant (Branta bernicla nigricans) has shifted northward from low-temperate areas to sub-Arctic areas over the last 42 years. We assessed the winter abundance and distribution of brant in Alaska to evaluate whether climate warming may be contributing to positive trends in the most northern of the wintering populations. Mean surface air temperatures...

Hierarchical spatial genetic structure of Common Eiders (Somateria mollissima) breeding along a migratory corridor Hierarchical spatial genetic structure of Common Eiders (Somateria mollissima) breeding along a migratory corridor

Documentation of spatial genetic discordance among breeding populations of Arctic-nesting avian species is important, because anthropogenic change is altering environmental linkages at micro- and macrogeographic scales. We estimated levels of population subdivision within Pacific Common Eiders (Somateria mollissima v-nigrum) breeding on 12 barrier islands in the western Beaufort Sea...

Environmental and human influences on trumpeter swan habitat occupancy in Alaska Environmental and human influences on trumpeter swan habitat occupancy in Alaska

Approximately 70-80% of the entire population of the Trumpeter Swan (Cygnus huccinator) depends for reproduction on wetlands in Alaska. This makes the identification of important habitat features and the effects of human interactions important for the species' long-term management. We analyzed the swan's habitat preferences in five areas throughout the state and found that swan broods...

Evaluating the validity of using unverified indices of body condition Evaluating the validity of using unverified indices of body condition

Condition indices are commonly used in an attempt to link body condition of birds to ecological variables of interest, including demographic attributes such as survival and reproduction. Most indices are based on body mass adjusted for structural body size, calculated as simple ratios or residuals from regressions. However, condition indices are often applied without confirming their...
