Data

The 1966-2018 North American Breeding Bird Survey dataset contains avian point count data for more than 700 North American bird taxa (primarily species, but also some races and unidentified species groupings). These data are collected annually during the breeding season, primarily June and May, along thousands of randomly established roadside survey routes in the United States and Canada...

Detailed data collected from the field and generated during diagnostic evaluation of whooping crane carcasses from the Eastern Migratory Population.

Data included in this release are from Pacific sand lance and water, sediment and suspended particulate matter collected at two sites in Puget Sound, Washington, which were evaluated for PCB concentration. PCB congener data are stored in the U.S. Fish and Wildlife Service's Environmental Contaminant Data Management System (ECDMS), accessible through the Wildlife & Environmental...

Hematology and body mass were studied in nine female and five male free-ranging wolves in the Superior National Forest handled 4-17 times during 1989-1993. The dataset includes the following data for each wolf studied: wolf identifier, dates caught, sex, age, body mass in kg, adjusted body mass in kg, and values of hemoglobin (Hb), red blood cells (RBC), mean corpuscular hemoglobin (MCH)

This data set is part of a data release as a companion to a published manuscript titled "Low renesting propensity and reproductive success make renesting unproductive for the Piping Plover, Charadrius melodus." The Condor: Ornithological Applications. Upon reproductive failure, many bird species may make a secondary attempt at nesting. This data set includes four tabular digital data...

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.

Values for predicted probabilities of avian species occupancy were determined using colonization-extinction models (MacKenzie and others, 2003) as implemented in R (Version 3.4.4; https://www.r-project.org/) via the colext function of the Unmarked package (Version 0.12-0; Fiske and Chandler 2011). Performance of a null model (without covariates) and 153 additional models that assessed...

Piscine orthoreovirus genotype one (PRV-1) is the causative agent of heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon (Salmo salar L.). The virus has also been found in Pacific salmonids in western North America, raising concerns about the risk to native salmon and trout. Here, we report the results of laboratory challenges using juvenile Chinook salmon, coho...

Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska-Siberia (WA-S), Northern Canada-Nunavut (NC-N), West-central Canada...

These data were collected to fulfill multiple Inter-agency agreements established by USGS and multiple partners: USDA Farm Service Agency, USDA Natural Resources Conservation Service, and the Honey Bee Health Coalition. In this study USGS scientists conducted floral resource and insect pollinator assessments across multiple land covers in North Dakota, South Dakota, and Minnesota from...

In this study USGS scientists collected pollen samples from honey bee (Apis mellifera) colonies distributed across North Dakota, South Dakota, and Minnesota, in 2015 and 2016. Sequencing of nuclear ribosomal loci was used to to determine the number and abundance of flowering plant taxa. The data contain counts of Operational Taxonomic Unit (OTU) reads of honey bee collected pollen from...

These data represent characteristics of trees used by Northern long-eared bats as roosts at three sites in Wisconsin, as well as characteristics of surrounding trees to compare characteristics of used versus available trees.
