Val and all,

Indeed White-browed and Masked Woodswallows do behave in this way, as I've often seen in the Capertee Valley on stormy summer afternoons. The dark underparts you saw indicate White-browed, but it's always worth searching these flocks for Masked which could be mixed in with them. Both White-browed and Masked call as you describe. The Dusky's call is harsher, more scratchy. Such graceful and exhilarating birds.

It was about 30 minutes before sunset and there was a storm approaching, lots of heavy dark clouds and very little wind. They were behaving as I would expect to see swifts behave in the conditions, circling very high over the trees which are about 60 meters tall (I think!) and some of the birds were at least that high again, some so high I could barely see them with the naked eye in the poor light. At a conservative guess there were about 40 that I could see, but there could have been many, many more out of my field of view behind the tree tops

I was unable to positively identify the species but they all appeared uniformly dark underneath in the poor light and were calling constantly with a gentle 'chup, chup' sort of sound.

Is this a know bebaviour of Woodswallow species?
