As we were preparing to leave the Coorong years ago Ian F. drew our attention to large almost dervish-like clouds of gnats in early-morning mating flights.
There are similar, though smaller,  crowds of small flies around at the  moment. Flying and swirling after minus 4 degrees doesn't seem to deter them. I've not noticed Grey fantails being particularly busy near these crowds. Which raises the question of birds' ability to "know" what's tasty and what isn't worth the hawking effort.  It just goes to show how different respective "eyesights" are.
