I hurry home from work on summer days eager to see what’s going on in my yard. Every summer evening is special, but last Wednesday at dusk was spectacular. As we sat having dinner on the front deck, the sky directly overhead was peppered with giant dragonflies. They were zigging, zagging, dropping straight down, zooming vertically and, in general, putting helicopters to shame with their aerial stunts. I know that as they were performing these feats, the dragonflies were simultaneously grabbing bugs with their front legs and stuffing the insects into their mouths. The only show more sensational would have taken place in prehistoric times when dragonflies had wingspans of 2.5 feet.
In the airspace above the dragonflies, about forty of our purple martins were swooping around, chattering and gobbling insects for bedtime snacks. We observed that no dragonflies got picked off by the martins. I’m guessing the dragons were too big a mouthful.
As the last rays of the sun were fading, the highest layer of the sky was filled with silent streams of gulls winging home for bedtime in the lake.
In less than an hour, we witnessed hundreds and hundreds of flight paths. Unlike O’Hare, no control tower filled with air traffic controllers was needed. And we are happy to report that, despite the congestion, no mid-air collisions occurred. Nature certainly has her act together.
