Large-scale survey Analysis

The North American Breeding Bird Survey Summary and Analysis webpages present 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.

MBR Software/Data/Workshops

The MBR Computer Software webpage lists programs available to download (or in some cases run online) for the analysis of wildlife data.

The Recent/Upcoming Workshops webpage lists upcoming and past workshops taught by PWRC staff, or colaborators for wildlife students or professionals interested in learning about statistical techniques for analysis of wildlife data.

The Data Sets and Analyses used in recent publications lists links to additional information (tables, abstracts, data) for recent publications by PWRC/MBR authors.

Learning About Birds!

The Bird Identification InfoCenter presents photographs, songs, videos, identification tips, maps, and life history information for North American birds.

The Bird Identification tips webpages provide tools for learning about birds.

The Patuxent Bird Quiz lets you test your knowledge of North American bird identification, distribution in winter (from the Audubon Christmas Bird Count) and summer (from the North American Breeding Bird Survey), and song. Note that we use the term "song" loosely, here, and that you might have look pretty hard to see some of the photographed bird species in North America!
