In 2000, Russ States began an informal Common Nighthawk migration count at the Oil City Marina from mid-August to mid-September. For the first several years the watch was manned on a sporadic basis. For the past 14 years, however, the number of observers has gradually increased and there has been daily coverage. The count begins about August 17 and ends the second week of September.

     In 2017, Mal Hays and Larry Towse began a second similar count at the Mill Creek Boat Launch along the Clarion River, near Strattanville, PA.
