30 Years of Bird Counts: An Analysis

Valley Forge Audubon Society has been conducting Spring and Christmas bird counts for more than 30 years.  VFAS tasked Ty Sharrow and Kelly Johnson to do a statistical  analysis of this data with the assistance of Dr. Paul Bernhardt of Villanova University.  The purpose of their analysis was to look at general population trends and how bird populations may have been affected by various factors over the years of the count.  Join Ty and Kelly as they present the results of their analysis in this Zoom presentation.
