Forward...into the past!

While on a late walk this evening, we came across this bird sitting in the road. When we got close, it would flutter around, then land again in the road. Kept returning to this spot, though.

I managed to get this close-up pic of the bird on our return route.

Can anyone ID it? Roz? Tracy? I recognize it, but can't remember the name... "nightjar"?

Is that behavior normal?
