Dear Fellow Ospreyers: I just wanted to spread the word that tomorrow--Sunday, Dec. 6--the Montgomery County Chapter of MOS is presenting a free slide show at the Black Hill Regional Park Visitor Center. The slideshow, entitled "Common Winter Birds of Montgomery County," will be presented by Bill Kulp. This talk will be geared toward new birders, from age six to adult, and is set for 2:30 to 4 p.m. Admission is free. Howard Youth hmyouth@erols.com Rockville, MD
