This is an antiquated version of the North American Breeding Bird Survey (BBS) dataset that has been superseded by a more recent release.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 1966-2021 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...
These data describe the distribution and abundance of Hydropsyche, a widespread and diverse genus of net-spinning caddisflies, in the Colorado River Basin. Abundance data, measured as catch rates, were collected by citizen scientists using light traps. We subsampled Hydropsyche spp. from light trap samples collected throughout the Colorado River Basin and measured the lengths and widths of mesothoracic tibia and first tarsal segments. Samples and measurements were processed at Grand Canyon Monitoring and Research Center in Flagstaff, AZ.
This dataset includes all North American Breeding Bird Survey data collected in Mexico between 2008-2018. These data were used as the basis for all analyses discussed in an associated publication: The North American Breeding Bird Survey in Mexico, 2008-2018 — A Status Report; https:doi.org/10.3133/cir1479. The records include avian point count data for all reported taxa (species, races, and unidentified species groupings). In addition to avian count data, this dataset also contains survey date, survey start and end times, start and end weather conditions, a unique observer identification number, route identification information, and route location information including country, state, and BCR, as well as geographic...

The 1966-2022 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 are roughly 24.5 miles (39.2 km) long with counting locations placed at approximately half-mile (800-m) intervals, for a total of 50 stops. At each stop, a citizen scientist highly skilled in avian identification conducts a 3-minute point count, recording all birds seen within a quarter-mile (400-m) radius and all birds heard. Surveys begin 30...

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).

Greater sage-grouse (Centrocercus urophasianus) have been declining both spatially and numerically throughout their range due to anthropogenic disturbance and loss and fragmentation of sagebrush (Artemisia spp.) habitats. Understanding how sage-grouse respond to these habitat alterations and disturbances, particularly the types of disturbances and extent at which they respond, is critical to designing management actions and prioritizing areas of conservation. To address these needs, we developed this spatially explicit model of the relationship between occurrence and abundance of greater sage-grouse and multi-scaled measures of vegetation, abiotic, and disturbance in the Wyoming Basins Ecoregional Assessment (WBEA)...

Conclusions: Frogs and toad species were more abundant and diverse where habitat patch diversity was high or where there were forested wetland edges. Relative abundances of amphibian populations correlated positively with metrics such as the length of edge between forest and wetland, and negatively with the presence of agricultural and urban land. Thresholds/Learnings: Synopsis: This study examined landscape-level relationships for frogs and toads by measuring associations between relative abundance and species richness based on survey data derived from anuran calls and features of land cover maps for Iowa and Wisconsin. Relative abundances correlated positively with metrics such as the length of edge between forest...

These data were compiled to evaluate the effects of low steady weekend flows on emergent aquatic insects during the first year of experimental Bug Flows below Glen Canyon Dam (2018) and recreation in Glen Canyon in the second year of Bug Flows (2019). Bug Flows are experimental flows that were released from Glen Canyon Dam in 2018 and 2019. The flows consist of low steady flows on weekends and have the goal of increasing aquatic insect production. These data were compiled for an outreach article providing Citizen Scientists with an update on ongoing research evaluating the effects of Bug Flows. Midge and caddisfly data were collected by Citizen Scientists using light traps. Angler data were collected under a paired...
This page provides access to antiquated versions of the North American Breeding Bird Survey (BBS) dataset that had been used in earlier analyses. 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. Accessing Historic Data The “Child Items” section below links to the historic data releases. Each archived release had included: all data that had been included in the previous release, plus one subsequent year of data, plus all taxonomic updates, data corrections, and/or other minor adjustments that had occurred in that intervening year Release Schedule The BBS...
Data files in this data series represent migrating bird count and habitat information collected during 1989, 1991, 1993, and 1994 field seasons at 13 riparian sites along the San Pedro River and its tributaries in southeastern Arizona, USA. At each site observations were made at up to 20 points, separated by 100 m arrayed along the riparian zone. Observation periods started at 20 minutes after sunrise, lasted for 7 minutes at each point and were completed within 4 hours. Bird detection and species identification were based on visual sighting, song, and call. Recorded observations were the number of individuals of each detected species detected using each detection method at each point and site within specified distance...

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...
