Survey of potential viral pathogens in the ceca of pen-raised mallards

The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and breeding a

Database collating previous laboratory investigations into the pathogenesis of avian influenza viruses in wild avifauna of North America

A compilation of previously published results exploring the pathogenesis of avian influenza viruses in wild avian species in North America.

Brodifacoum isomer formulation study

Body weight and weight change during course of study, estimates of food and brodifacoum consumption, observations of test birds during feeding trial and at necropsy, hematocrit, and prothrombin time

Attribution of stream habitat assessment data to NHDPlus V2 and NHDPlus HR catchments within the Chesapeake Bay Watershed

This data release links habitat assessment sites to both the NHDPlus Version 2 and NHDPlus High Resolution Region 02 networks using the hydrolink methodology. Linked habitat sites are those compiled by the Interstate Commission on the Potomac River Basin (ICPRB) during creation of the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) for benthic macroinvertebrates (https://datahub

North American Bird Banding Program Dataset 1960-2023 retrieved 2023-07-12

The North American Bird Banding Program is administered through the U.S. Geological Survey (USGS) Bird Banding Laboratory (BBL), Eastern Ecological Science Center at the Patuxent Research Refuge (EESC) and the Bird Banding Office (BBO), Environment and Climate Change Canada (ECCC). The respective banding offices have similar functions and policies and use the same bands, reporting forms and data f

Data describing habitat use and availability for wild waterfowl in California, USA

These data describe the overlap of wild waterfowl and domestic poultry operations in California, USA. These data support a paired USGS publication.

Data from Assessing the added value of antecedent streamflow alteration in modelling stream condition

The dataset contains long-term and short-term summaries of streamflow alteration and measures of biological condition (fish multi-metric index). Streamflow alteration metrics include the magnitude, duration, frequency, and seasonality of high and low flow streamflow. Biological condition was estimated from the National Rivers and Streams Assessment and National Water Quality Assessment fish sampli

The North American Breeding Bird Survey, Analysis Results 1966 - 2022

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validatio
