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. Since then, the number of observers gradually increased and there has been daily coverage. The count begins about mid August and ends the second week of September. It's held nightly from 6:30-8:00 pm. 

     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.
