Tug of War

A seasonal tug of war is now underway in the Mid-Atlantic region.The day began with a brushing of frost,then progressed into blustery conditions as cold and warm air masses collided.The warm air will win out beginning Thursday afternoon.Chipping sparrows are in the region for breeding and some chimney swifts have been spotted the last few days.They eat insects on the wing,providing a most useful service.
