Black-bellied Whistling-Ducks — near Pleasantville, Berks County; June 4, 2006. Photo by Dave DeReamus. Note the black belly, white wing patch, red bill, and light eye ring on the gray face. All four birds are in this picture, although the fourth bird is hidden by the dead gray stems just below and in front of the tallest bird. These birds represent the 1st record for Berks County. There are very few records of them for Pennsylvania.
