Description:

Abstract:

This website consists of a series of interactive programs and maps that describe population change for North American Birds summarized from North American Breeding Bird Survey (BBS) data. Metadata for the BBS exists <ftp://cameron.cr.usgs.gov/pub/nbii_metadata/brdpwrc0004.html>, and these metadata provide specific information on the analysis programs and summary information. Metadata on digitized maps and route paths exists at: <http://nationalatlas.gov/birdm.html>.

Purpose:

These interactive programs and maps are designed to provide public access to analysis results from BBS data. A statement regarding the elements of the website, and a general discussion of the methods, is available at (<http://www.mbr-pwrc.usgs.gov/bbs/intro04.html>). Analysis of survey data can be controversial, and any user of the information should recognize that alternative approaches exist. These programs provide results based on methods that have been accepted in the published literature for many years, but also provide alternative approaches to analysis. Users also have access to actual data from the survey, at (<http://www.mp2-pwrc.usgs.gov/bbs/>). Standard disclaimers for use of information are also provided (<http://www.mbr-pwrc.usgs.gov/bbs/disclaim.html>).

Supplemental_Information:

Information regarding the function of individual elements of the website are available throughout the site, and include help files at (<http://www.mbr-pwrc.usgs.gov/bbs/helpind.html>).

Attribute_Accuracy:

Attribute_Accuracy_Report: For metadata on BBS routes, see: http://nationalatlas.gov/birdm.html. For metadata on the survey, see: <ftp://cameron.cr.usgs.gov/pub/nbii_metadata/brdpwrc0004.html>,

Logical_Consistency_Report:

For mapping applications, Arc/INFO software was used to create and maintain topological relationships between features. The Arc/INFO command BUILD was run to ensure the topological consistency of the data set.

Completeness_Report:

<ftp://cameron.cr.usgs.gov/pub/nbii_metadata/brdpwrc0004.html>. Maps contain grid polygons which cover the land mass for North America except Mexico and the Northern part of Canada. It is possible small islands are not covered by this grid.

Methodology:

Methodology_Type: Trend analysis using Poisson regression methods, with supplemental analyses conducted using LOESS smoothing procedures.  Geographic smoothing for maps is conducted using inverse distancing of route data.
