The 111th Annual Audubon Christmas Bird Count is this Tuesday, with thousands of volunteers helping the census. Locally, the Catskill-Coxsackie count is headed by two local ornithological enthusiasts, Richard Guthrie and Larry Federman and covers a fifteen-mile radius centered at Green Lake, and branches out 7.5 miles in all directions. New Baltimore marks the territory's northern boundary, while the eastern line extends into Columbia County. A team will cover the Hudson River from Coxsackie to Athens, another will focus on grasslands preserves, another on Round Top, and a Coxsackie Flats group. Imbought Bay at the tip of Catskill marks the southernmost border. E-mail Richard Guthrie at gaeltic@capital.net to get involved. In Dutchess County, contact Susanne Norris at 845-229-0174 or make reservations at 845-486-1966 for meeting from 10 a.m. to 12 noon at Wallace Center, Roosevelt-Vanderbilt National Historic Sites, in Hyde Park.
