Last night, seven or eight Common Nighthawks flew large loops around my Centennial neighborhood. Presumably, they were feeding on flying ants. While I couldn't find these in my yard yesterday, I've seen them in August in previous years, and, yesterday, a FaceBook user also posted a photo (from Arvada) of a swarm of winged ants. 

Why yesterday? Perhaps because we got a brief (too, too brief) rain in Centennial. Perhaps other areas of Denver got this, too? As Dave Leatherman once told me, this softens up the ground and lets the winged ants emerge. It also explains the centuries-old association of nighthawks with rain.

Just a bit of conjecture, though.

I had 8 Common Nighthawks last night from about 6:30-7:15 just a bit north of you near Chambers and Quincy.

I love nighthawks, I'm not seeing so many anymore, though! ☹️

Jared and CObirders,

Last night about 7:30 PM I saw dozens of nighthawks flying low over Louisville all slowly heading south....  I think they were hunting while migrating?!
