45 Years of Bird Population Trends Thursday, May 16, 7:30 p.m at Woodend Every June since 1966, experienced birders have documented the populations of roadside birds throughout the U.S. and southern Canada. Now ornithologists at the Patuxent Wildlife Research Center have compiled from this Breeding Bird Survey data, an interactive database showing abundance and trends of 400 species.  Dr. John Sauer, lead researcher on the project first begun by Chandler Robbins, will tell us about the significant trends and explain how to use the database. Doors open at 7 for refreshments and browsing in the Sanctuary Shop. (Members will receive a special 20% discount.) The program begins at 7:30. No charge.
