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.
