At 4:00 this afternoon, 4 Common Ravens were in a tall Norway Spruce at the southwest corner of Speedwell and West Hanover Avenues in Morris Plains. The Ravens left the roost and flew westerly towards Greystone Park Psychiatric Hospital. This is the second sighting of Ravens in this area in the past two weeks. On June 30, a single Common Raven flew over the Greater Morristown YMCA on Horsehill Rd. in Cedar Knolls.
