This data package presents legacy data on Emperor Goose, Cackling Goose, Black Brant, and Greater White-fronted Goose, breeding biology, behavior, and morphology collected at study sites near Kokechik Bay on the Yukon Delta National Wildlife Refuge (previously Clarence Rhodes National Wildlife Refuge), Alaska during the summers of 1982 through 1988. These data were collected to provide a basis for the evaluation of long-term changes in Emperor Goose and other waterfowl biology on the Yukon-Kuskokwim Delta, Alaska.
These data were developed to support an effort to characterize migration strategies in the U.S. Great Plains and Canadian Prairies and to explore sources of heterogeneity in their migration strategy, including space use, timing, and performance. Data come from locations and other information related to 58 marked Whooping Cranes (Grus americana) from 2010–2016. These data represent basic information about space use during migrations of marked whooping cranes, including intensity of use and fidelity.

These data are in two tables relating to fall age ratios (number of juvenile birds : total birds aged) of Black Brant (Branta bernicla nigricans) staging in Izembek Lagoon, Alaska, since 1963. The first table is observation data for the age classes of Black Brant during surveys, and associated survey characteristics. The second table contains model-based estimates of age ratios by year along with Standard Error (SE), and 95% Bayesian credible intervals around estimates.
Sandhill cranes are a long-lived bird species found in wetland-rich landscapes across North America. This dataset includes locations of 5 cranes during a single autumn migration from their breeding areas in northeastern Asia and south through Alaska, central Canada, and the Great Plains. The migration ends in northern Texas and northern Mexico. These data were used as a case study to highlight the utility of a continuous-time movement model to characterize animal migration and networks.

This dataset represents a modeling effort intended to explore the impacts of oiling on migratory birds. The purpose of this model is to provide a first principles approach to predict potential biological impacts of altered energetics dynamics in north American migratory birds due to oiling of feathers. This data includes predicted theoretical impacts on migration timing, wintering latitude, starvation rates, and increased food uptake. This data was generated through model implementation in R (R Core Team 2020; Version 4.0.4).
This project will develop species distribution models (SDM) to evaluate current and future occurrence and density of wetland-dependent birds relative to several predictors, including land use patterns, wetland condition and connectivity, geomorphic setting and climate. These tools will suggest which wetland-dependent bird species appear most vulnerable to climate and land use change based on the expected extent of range change under various scenarios. Knowledge of natural history and habitat associations of species coupled with coefficients from regression models will provide insight into the potential reasons for species vulnerability. This information will be valuable in the development of management strategies.

These data are daily summary checklists of all bird species observed at U.S. Geological Survey, Alaska Science Center (ASC) field camps in Western Alaska. Data include species observation details such as observers, dates, location, and number of individuals seen. Included are data from three camps along the Kashunuk River within the Yukon Delta National Wildlife Refuge ("Old Chevak", "River Camp", and "Square Bend") during the summer field seasons: 1985-2012.
This package contains information collected during avian and habitat survey data at five national parks/monuments: Cape Krusenstern National Monument, Gates of the Arctic National Park and Preserve, Kobuk Valley National Park, Noatak National Preserve, and Bering Land Bridge National Preserve. The objectives of the surveys were to document the occurrence of 90 percent of the bird species likely to occur in montane habitats and determine the distribution and abundance of species of special concern.
These data were developed to support an effort to characterize migration strategies in the U.S. Great Plains and Canadian Prairies and to explore sources of heterogeneity in their migration strategy, including space use, timing, and performance. Data come from locations and other information related to 58 marked Whooping Cranes (Grus americana) from 2010–2016. These data represent basic information about migrations of marked whooping cranes, including dates of initiation and termination of migration, time in migration, distance of migration, number of stopover sites used, and other metrics. Also included are data related to individual sites used by whooping cranes during migration.
Predicted climate impacts on arid U.S. Great Basin wetlands will alter their number, distribution, and quality (e.g., salinity). The scarcity and isolation of these wetlands make them essential not only to wildlife but to ranchers, farmers, and urban areas that rely on their ecosystem services. Great Basin wetlands are important habitats for migratory birds at high volumes, but they become concentrated mineral brines at low volumes, narrowing waterbird food resources as salinity rises. Thus, many resource managers need to answer two questions: How will climate change affect migratory bird species dependent on climate-sensitive wetlands? How should management strategies balance human-consumer uses of these water...
The whooping crane (Grus americana) is a bird species in North America currently protected under federal endangered species legislation in the United States and Canada. The only self-sustaining and wild population of whooping cranes nests in and around Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada. Cranes from this population migrate through the Great Plains of North America and winter along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands. These data support efforts to delineate a migration corridor for this population that can be used for conservation planning activities, including targeting conservation, mitigation, and recovery...

The Nature Conservancy - Great Lakes Program is leading the development of a scalable (Great Lakes wide, individual lake basin, to coastal reach within a lake basin) rule-based spatial model for ranking the relative importance of coastal lands and waters as habitat for migrating birds. Results will guide conservation actions including land acquisition, land and water management and restoration, and development of wind energy facilities. Specifically, the team will: 1) refine, create and integrate migratory bird stopover habitat models which depict the distribution of potential stopover sites along or near the shorelines of Lakes Michigan, Huron, Erie, and Ontario; and, 2) develop an online portal that will deliver...

Sediment accumulation threatens the viability and hydrologic functioning of many naturally formed depressional wetlands across the interior regions of North America. These wetlands provide many ecosystem services and vital habitats for diverse plant and animal communities. Climate change may further impact sediment accumulation rates in the context of current land use patterns. We estimated sediment accretion in wetlands within a region renowned for its large populations of breeding waterfowl and migrant shorebirds and examined the relative roles of precipitation and land use context in the sedimentation process. We modeled rates of sediment accumulation from 1971 through 2100 using the Revised Universal Soil Loss...

Land-use change, invasive species, and climate change have dramatically impaired ecosystem function worldwide. Understanding how changes to ecosystems impact species of conservation concern is essential for effective conservation delivery. Of particular importance are environments that provide disproportionate ecosystem services. Throughout the Great Plains Landscape Conservation Cooperative, playas provide disproportionate ecological services, including essential stopover habitat for migratory waterbirds. Anthropogenic change to playa distribution, abundance, and function may impact the ecosystem services provided, with demographic consequences for priority species. We will address partner needs by developing a...

Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance...
