BPP summary results using records validated as of 10/19/2015

These results represent exploratory work with the BPP in its current state for the purpose of: 1) testing out a few concepts of looking at and analyzing the data, 2) seeing the current state of the validated records for species and locations, and 3) looking at some basic summaries of species' phenology and their trends to see if/how North American migratory birds shifted their phenological behavior from the late 1880's to 1940's. As such, these are not fit for publication. Unless otherwise specified, these figures and tables are using data from any location where the species was recorded by a BPP observer. For the summaries by location: blank fields indicate that there were not enough observations or they did not contain enough information to the capture the species' general phenology or trends for this location.

If you have any questions about the methods used or content of any of these figures, maps, or tables please feel free to contact the BPP Coordinator: Eric Ross (
