That would make sense and, for the same reason, we don't see those fence lizards (we called them that as kids, not too sure what the actual species was), box turtles and the frog population has plummeted. Building and pollution has taken its toll.
What happened? This thread was out to about 15 or 16 pages the last time I looked!
Loud and clear at my place. I recorded this on my phone in July, cleaned it up a bit in Logic Pro. Don't hear so many of them now, but in the spring and early summer they are a constant serenade. Maybe this will bring back a few memories for you.

That is some art of fancy in that Thunder Road Part1 clip. The guy rolls the car twice and once he's upright again heads the other way like a bat out of hell. Ha!
Woops - just noticed that. Is that a loop you made or the actual sound? Maybe the cleaning up program you used made them sound more raucus and relentless.
I grew up in th 60's and have very fond memories of Bamber Lake and Camp Colunmbus. Every summer I would vacation on the other side of the lake with my grandparents and once a week we would make our way down the small path, through the honeysuckle. Past the old red bridge and to the camp. There, the boys would put on an Indian camp fire and we would hold our lighted punks (to keep the mosquitos at bay) and listen to ghost stories. It was a real event for us kids! I returned to Bamber Lake a few years ago and found that my grandparents house was torn down an replaced with a contemporary. My father helped build that house in 1955. It was a vacation home for the family before my grandparents moved in after they retired. Many of my relatives lived and grew up there but I found only one cousin who is still there. The old red bridge is gone. The old path is now a wide dirt road. The box turtles, lizards, snapping turtles, frogs, whippoorwills, bob whites are all quiet now. It tore at my heart to see the change. I will always remember Bamber Lake and Camp Columbus as a very important part of my childhood.
