One of my Hank Williams favorite songs was about whippoorwills.

Hear that lonesome whippoorwill
He sounds too blue to fly
The midnight train is whining low
I'm so lonesome, I could cry
I've never seen a night so long
And time goes crawling by
The moon just went behind the clouds
To hide its face and cry
Did you ever see a robin weep
When leaves begin to die?
Like me, he's lost the will to live
I'm so lonesome, I could cry
The silence of a falling star
Lights up a purple sky
And as I wonder where you are
I'm so lonesome, I could cry
That's a good one
It's a lonesome song, ain't it?
Ain't that lonesome, woo
Now you can't get any much lonesome right, can you?
Want to whip a will so lonesome it can't fly
He done got lonesome, man
He needs some company, bad

I?m So Lonesome I Could Cry lyrics ? Sony/atv Acuff Rose Music

They were everywhere 70 years ago. Back in 195o they kept us awake. My dad shot one that was sitting on our back porch. In the 1970's I heard them at daylight.

I haven't heard ones call for 30+ years!
