These data support a paired USGS publication and document the use of retention ponds on commercial poultry farms by wild waterfowl.
thumbnail
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.
thumbnail
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.
thumbnail
These data describe the affects of elastic leg-loop harnesses on the reproductive success and behavior of adult Common Terns and the growth and behavior of juvenile Common Terns. These data support a USGS authored manuscript.
thumbnail
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.
thumbnail
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.

A compilation of previously published results exploring the pathogenesis of avian influenza viruses in wild avian species in North America.
thumbnail
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.
thumbnail
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.
thumbnail
These videos show a pair of common terns usurping a least tern nest with chicks. These data support a paired USGS authored manuscript.
thumbnail
This data release details the results of avian influenza sampling of dabbling ducks in Maine and Maryland. These data support an associated USGS publication.
thumbnail
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 release contains model outputs depicting the probability of an H5 or H7 avian influenza outbreak at any given point in the continental United States for each week of the year.
thumbnail
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.

We collated existing quantitative data on avian dietary composition of 58 waterbird species that make use of the Chesapeake Bay. From this database, we quantified the relative importance of forage taxa to the diets of each waterbird species. This data will enable us to develop a comprehensive suite of forage taxa indicators whose abundance and distributions can be monitored as a proxy for Chesapeake Bay ecosystem health. These data support a paired USGS authored publication.

In an effort to facilitate research into the period between fledging and first breeding of juvenile terns we examined the impact of various combinations of harness types (backpack, leg-loop, and 3D printed harnesses), harness materials (Conrad-Jarvis automotive ribbon, Stretch Magic elastic thread, and Teflon ribbon), and transmitter types (CTT LifeTag and Lotek Nanotag) on a surrogate for juvenile terns, 28 day-old Japanese Quail (Coturnix japonica. This species was selected due to similarities in adult mass and downy feathering of juveniles), in a 30-day experiment. We monitored for abrasion at points of contact and tag gap issues via daily exams while also recording mass and wing cord as indices of growth. This...
This is a data release for models indicating suitable habitat for waterfowl at a 1km resolution across China. Faced with limited data, we built species distribution models using a habitat suitability approach for China’s breeding and non-breeding waterfowl. An extensive review of the literature was used to determine model parameters for habitat modeling. Habitat relationships were implemented in GIS using land cover covariates. Wintering models were validated using waterfowl census data, while breeding models, though developed for many species, were only validated for the one species with sufficient telemetry data available. We developed suitability models for 42 waterfowl species (30 breeding and 39 wintering)...
