Play the video below to watch ravens in aerobatic flight over a hill near Kanab, Utah, USA. The clip has three parts:
Fig 1. Video of ravens in aerobatic flight, near Kanab, Utah.
The ravens didn't appear to be feeding. Wikipedia says that crows do a sort of aerial jousting to establish a pecking order. Others have suggested it is courtship or pair-bonding behaviour, or simply playing (it certainly looks like fun!).
This was mid-May in 2008, at around 6pm.
Hi Jim, I just saw the same thing here in Edmonton on a cliff overlooking the river valley. It was amazing. Had to do a google search to see if I was the only one who has seen this. Glad to see I'm not. :)

I saw some crows doing similar soaring and aerobatics over a row of trees at the edge of a field, in Ottawa.
