These data describe the status of eggs in nests which had a foster egg added to them as part of an effort to relocate a common tern colony on Poplar Island. One data file (McGowanEtAl2018_FosterNestData_Data.csv) contains the data regarding the observations, while one definitions file (McGowanEtAl2018_FosterNestData_Definitions.csv) details the data.
These data support a paired USGS publication and document the use of retention ponds on commercial poultry farms by wild waterfowl.

These data, which support a paired USGS publication, document the movement and infection status of mallards captured, marked, and tested at a wintering site in Tennessee. Data document differences in movement ecology between mallards infected and not infected with HPAI H5N1.

These data describe the results of virus isolation from oropharyngeal/cloacal swabs and testing of sera by a commercial blocking enzyme-linked immunosorbent assay (bELISA) and hemagglutinin (HA) specific testing by microneutralization (MN) and hemagglutination inhibition (HI) for Lesser Scaup in both the Atlantic and Pacific Flyways and Greater Scaup in the Pacific Flyway. These data support a USGS published manuscript.

These data, which support a paired USGS publication, describe the efficacy of several management practices for reducing the presence of herring gulls in the nesting colonies of Common Terns. This data was collected on Poplar Island, located in the Chesapeake Bay portion of Maryland.

These data describe the creation, execution, and results of an effort to model the risk of avian influenza transmission across the wild waterfowl - domestic poultry interface at weekly intervals for the contiguous United States.
These data describe the spatio-temporal distribution of dabbling duck species across the continental United States during four biologically relevant seasons. This dataset contains two types of distribution models: (1) probability of presence, and (2) abundance. The model type, species, and season depicted in a raster are defined in the file name. File names begin with either abun (indicating that it is an abundance model) or prob (indicating a probability of occurrence model). Following model type is species, for which there are 10 provided: ABDU (American Black Duck), AMEW (American Wigeon), BWTE (Blue-winged Teal), CITE (Cinnamon Teal), GADW (Gadwall), AGWT (Green-winged Teal), MALL (Mallard), MODU (Mottled...

Predicted Avian Influenza Prevalence for Wild Waterfowl Species Across the Continental United States
This data release provides the predicted proportion of birds testing positive for IAV for each species at weekly intervals for each county centroid in the continental United States. This data supports a paired USGS publication.

Wild lesser scaup from the Chesapeake Bay, captured and implanted with satellite transmitters for a separate ecology study, were opportunistically sampled for avian influenza. These data detail the virological sampling results, obtained post release, which include a single positive for clade 2.3.4.4 H5N1 virus of the A/goose/Guangdong/1/1996 (Gs/GD) H5N1 lineage of highly pathogenic IAV. These data also include the movements of the infected bird from release until death as well as four conspecifics marked and released concurrent with the HPAI positive bird. These data support a paired publication.

These data describe the area of different habitat covered in water as determined via three approaches: manual surveys, digitized aerial imagery, and categorization of the newly available dynamic surface water extent dataset derived from satellite imagery. These data support a scientific publication.

This data release details the results of avian influenza sampling of dabbling ducks in Maine and Maryland. These data support an associated USGS publication.
This data layer depicts the weekly estimates of the relative risk of avian influenza transmission from wild waterfowl to domestic poultry. These data represent an early phase of ongoing model development and the inclusion of additional parameters is upcoming.
This data layer depicts the relative susceptibility of poultry to the transmission of Avian Influenza from wild birds based upon poultry type and density for the contiguous United States.
While small unmanned aerial systems (UAS) present a unique opportunity to survey avian populations while limiting disturbance, relatively little is known about how this method compares with more traditional approaches. In this study we compared population estimates of a mixed-species egret colony in the Chesapeake Bay (Maryland, USA) derived from UAS photo counts, flush counts, flight-line surveys, and in-colony nest counts along with the time required to derive an estimate via each approach. These data support a larger USGS manuscript.

While nest attentiveness plays a critical role in the reproductive success of avian species, little is known regarding the nest attentiveness patterns of many species during incubation. However, improvements in both video monitoring and temperature logging devices present an opportunity to improve our understanding of this aspect of avian behavior. To evaluate the ability of these technologies to document fine scale behaviors during incubation we monitored 13 nests across two Common Tern (Sterna hirundo) breeding colonies with a paired video camera - temperature logger approach, while monitoring 63 additional nests with temperature loggers alone. We also monitored nests and recorded hatching success, allowing us...

This data layer depicts the weekly relative effective waterfowl populations across the United States based upon predicted abundance and viral prevalence by species. These data have been produced to allow for visualization of how different factors impact transmission risk and may be advanced in future iterations to include additional species.
