Most Recent Update: 16 April 2012.
This website presents population change information for more than 400 species of North American birds, as estimated from the North American Breeding Bird Survey. Estimates of trend (interval-specific estimates of population change), annual indices of abundance, and maps of abundance and population change for these species are presented for a variety of regions.
This website contains the first public copy of 1966 - 2010 BBS analysis results. We welcome comments on the results presented here. Public review and feedback of the results are a critical part of the scientific review of the website, and we thank you in advance for taking a careful look at these summaries.
Note that some of the bird species names we use out-of-date; we are in the process of updating taxonomy to correspond to the most recent AOU Checklist Update .
