I was interested to see the reports this evening on nighthawks, as I got home from work a short while ago and got a call from fellow Clarion Co birder Mal Hays. He has been doing nighthawk migration counts on the Clarion River north of Clarion at Mill Creek. The highest count so far had been somewhere around 40 birds, and when I was there with him on Monday evening I saw 13. However this evening, there was a huge increase of birds and his estimate for the hour and a half of counting was 236. He believes he saw actually over 400 birds but in trying to not double count, his best estimate of individuals was lower. Either way, a great count of nighthawks for the county ! To my knowledge, no one has ever monitored the Clarion River for nighthawks before, so fascinating to see the types of numbers he has had.
On a separate note, he has had a whip-poor-will calling several evenings just at the end of the count, and I was fortunate to hear it Monday evening just starting to call as I left around 8:20 pm.
