Feb 18, 2011 — Birders in the Northeast expect to see fewer robins and more redpolls as thousands of citizen scientists across North America get out their tally sheets for the 14th annual Great Backyard Bird Count, sponsored by Audubon and the Cornell Lab of Ornithology. Pat Leonard, of the Cornell Lab, helps coordinate the annual weekend count. She says the survey, which began this morning and continues through Presidents' Day, gives a snapshot of bird populations and migration trends. Leonard says the event typically records millions of observations.
