Breeding Bird Survey - Starting points

The North American Breeding Bird Survey (BBS), which is coordinated by the Biological Resources Division and Canadian Wildlife Service, is a primary source of population trend and distribution information for most species of North American birds. The BBS was initiated during 1966 by Chan Robbins and his associates at the Patuxent Wildlife Research Center to monitor the populations of all breeding bird species across the continental U.S., Canada, and Alaska. Approximately 2200 skilled observers participate in the survey each year. The BBS has accumulated 30 years of data on the abundance, distribution, and trends for more than 400 species of birds. These data are widely used by researchers, various federal and state agencies, non-governmental organizations, and the general public. Analyses of BBS data by PWRC statisticians have been instrumental in the development of innovative approaches for analyzing trends of wildlife populations.

Thus, BBS data should be regarded as provisional since subsequent reviews may result in significant revisions to the data. Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. \n\nThese data have been processed successfully on a computer system at the USGS Patuxent Wildlife Research Center, however no warranty expressed or implied is made regarding the accuracy or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty. This disclaimer applies both to individual use of the data and aggregate use of the data. It is strongly recommended that these data are directly acquired from a USGS Patuxent Wildlife Research Center or Canadian Wildlife Service source, and not indirectly through other sources which may have changed the data in some way. The U.S. Geological Survey and the Canadian Wildlife Service shall not be held liable for improper or incorrect use of the data retrieved from the North American Breeding Bird Survey data retrieval Internet site. \n\nNot all data available on this site meet the various methodological criteria of the BBS. Run type codes are used to distinguish between routes that meet BBS criteria and those that do not. Run type \"1\" is acceptable data; run type \"0\" is unacceptable data for BBS purposes. The run type codes for each route are available in the \"weather data\" file. See the Run Type link in the Help section for a more complete discussion of run type codes and their application. \n\nInformation concerning the accuracy and appropriate uses of these data may be obtained from the U.S. or Canadian National BBS Coordinator. \n\nThese data are the result of efforts by thousands of U.S. and Canadian BBS participants in the field, as well as, USGS and CWS researchers and managers. All publications based on these data should acknowledge all of these efforts. If a publication is based solely on the analysis of BBS data, we suggest that you involve the BBS office with the writing and/or review of the manuscript. We would also appreciate receiving a reprint or photocopy of any such article at the time of its publication."]
