Whip-poor-will

Tonight a single whip-poor-will was heard in the hollow. Several of these birds return annually from their winter homes along the Gulf Coast and southward to the hollow for the warmer months.

I was once attacked by a whip-poor-will along a lonely country road late at night after my pickup broke down. It beat me on the head and face with its wings and body again and again, until I ran away. Then it returned to its loud, rhythmic calls. What was that about, I wonder?
