DATA PAGE All known and published CBC results for Minnesota related census areas are included in the data contained at this web site. Several methods of searching and presenting CBC data are available via the links below. These tools can output summarized CBC data for a specific CBC Location, specific Species, or specific Count Season; including all data, or limited to include a specific range of CBC seasons. GRAPHING allows you to visualize data by producing graphs of annual statistics for either the Number of Species, or Total Census observed at a single Location. Graphs are displayed in GIF format. SUMMARIES produce a detailed compilation of census data based on the species, location, or seasons desired. SPREADSHEETS produce a table of summarized data, allowing comparisons of CBC totals between different locations, or seasons. A few COMPOSITE lists are available for curiosity, while the SEASONAL REVIEW included links to written summaries of CBC seasons. Both Audubon, and Minnesota reviews are available for most CBC seasons.
