North American Breeding Bird Survey, California, bird, bird count, point count
The North American Breeding Bird Survey uses standardized, statistically rigorous protocols to deliver scientifically credible measures of the status, trends, and environmental associations of North American birds. Federal, State, and local resource planners throughout the U.S. and Canada make extensive use of BBS information to identify at-risk species and to make wildlife management decisions.
To create this dataset, a few of the datasets available online were combined. The "50 stop" data and the "species list" were used and joined with a shapefile of approximate stop locations generated by CDFW staff. Negative detections were recorded, but removed from this dataset due to size constraints.

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 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 every bird seen or heard within a quarter-mile (400-m) radius. Surveys begin 30 minutes before local sunrise and take approximately 5 hours to complete. Routes are sampled once per year, with the total number of routes sampled per year growing over time; just over 500 routes were sampled in 1966, while in recent decades approximately 3000 routes have been sampled annually. 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 coordinates of route start point, and an indicator of run data quality.

This database, identified as the North American Breeding Bird Survey Dataset, has been approved for release and publication by the U.S. Geological Survey (USGS) and the Canadian Wildlife Service of Environment and Climate Change Canada (ECCC). Although this database has been subjected to rigorous review and is substantially complete, the USGS and ECCC reserve the right to revise the data pursuant to further analysis and review. Furthermore, it is released on the condition that the USGS, the U.S. Government, the ECCC, and the Canadian Government may not be held liable for any damages resulting from its authorized or unauthorized use. Use of these BBS data should be formally recognized in publications, presentations and other outlets via appropriate citation and acknowledgements.

If a publication is to be based on the analysis of BBS data, we encourage you to read and understand these metadata and supporting documents. The National BBS staff are also available to address any questions regarding the collection and presentation of these data. Also, depending on time constraints and other factors, BBS staff may be available to assist with the writing and/or review of the manuscript. It is in the best interest of the BBS program to demonstrate the utility of the data. One way we do this is by posting a BBS-based bibliography. Upon publication of your research, we encourage you to send the National BBS office a quick note with a link to your paper or a pdf copy so we can include it. Thank you for supporting the BBS program and we look forward to learning of your work.
