These data identify the time (0-1 min, 1-2 min,or 2-3 min) and distance (≤50 meters, >50 meters) category when birds were first detected during 3-minutes point counts at stop locations associated with North American Breeding Bird Survey routes or route equivalents that were surveyed on dates between 2009 and 2016 and provide point location coordinates of stop locations along North American Breeding Bird Survey routes or route equivalents within (or within 60 miles) the Gulf Coastal Plains & Ozarks Landscape Conservation Cooperative boundary.
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-validation model selection procedure was used to select the best model for each species.

Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We proposed to use correlated-detection occupancy models to develop indicators from the North American Breeding Bird Survey data. The indicators were used to test hypotheses regarding changes in range and distribution of breeding birds. The results will support the Northeast Climate Science Center’s Science Agenda, including the science priority: researching ecological vulnerability and species response...

Abstract (from Ecology and Evolution) Climate variation and trends affect species distribution and abundance across large spatial extents. However, most studies that predict species response to climate are implemented at small spatial scales or are based on occurrence‐environment relationships that lack mechanistic detail. Here, we develop an integrated population model (IPM) for multi‐site count and capture‐recapture data for a declining migratory songbird, Wilson's warbler (Cardellina pusilla), in three genetically distinct breeding populations in western North America. We include climate covariates of vital rates, including spring temperatures on the breeding grounds, drought on the wintering range in northwest...
This is an antiquated version of the North American Breeding Bird Survey (BBS) dataset that has been superseded by a more recent release. Unless visitors have a specific need for these archived data, they should return to the Main BBS Dataset Page and choose the most recent data release, as that one will include all BBS data released to date. The 1966-2019 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes...
Data files in this project were used in an integrated population model for three breeding populations of Wilson’s Warbler (Cardellina pusilla). Data span the years 1992-2008. Data include counts from the North American Breeding Bird Survey (BBS; https://www.pwrc.usgs.gov/BBS/RawData/; wiwa_bbs.csv), adult capture histories (wiwa_ch.csv) and age-specific capture data (wiwa_pdat.csv) from the Monitoring Avian Productivity and Survivorship program (MAPS; http://www.birdpop.org/pages/maps.php), and covariate data derived from the ClimateNA (https://sites.ualberta.ca/~ahamann/data/climatena.html; wiwa_cmd_wt.csv and wiwa_tave_sp.csv) and National Centers for Environmental Prediction (NCEP) ⁄ National Center for Atmospheric...

Estimates are derived for each species using the 1 of 4 alternative models, and a cross-validation model selection procedure was used to select the best model for each species. Metadata for the BBS data used to produce these estimates is available from a USGS ftp site (ftp://ftpext.usgs.gov/pub/er/md/laurel/BBS/DataFiles/). Metadata associated with this data product provides information specific to the analysis results.

This is the primary ScienceBase page for accessing North American Breeding Bird Survey (BBS) data. The BBS project measures bird populations on an annual basis. It has been in operation for more than 50 years, monitors 700+ types of birds, and spans the continent (map at right shows sample locations in red). More information about BBS history, methods, and past and ongoing applications of project data can be found in the "Related External Resources" section below. Accessing the Data The BBS releases its data on an annual basis. The “Child Items” section below provides links to the most recent as well as historic data releases. Each annual release includes all previously released data, plus all subsequent taxonomic...
A biologist and field crew from Northern Prairie Wildlife Research Center visited sites nine times throughout the breeding season (late May to mid-July) to record counts of grassland birds. Surveyors applied North American Breeding Bird Survey methodology to obtain counts at On-, Near-, and Off-road Stops, but unlike the North American Breeding Bird Survey, which features a single survey at each site, three replicate surveys were conducted on back-to-back-to-back days during each survey period to facilitate estimation of detection and occupancy probabilities. Assignment of surveyors to individual sites followed a design protocol that allows observer effects to also be estimated. The biologist visited each site once...
