The recent postings of sightings of swifts reminds
me of an afternoon in the early 1980's when at a friends's property in the West
Cooroy hills (about 25 miles west of Noosa). At the edge of a storm cell
directly above me, there were literally 100's of swifts catching the insects
that had been driven ahead of the storm front. I do not know which
species of swift they were but clearly a large swift with their perfect
boomerang shape. They were the same species and they stacked in layers: one
layer above the other going very high. Then it rained. And that was that. Never
saw them again. Not a one.
