Great footage Chris.
While I was working in the Murchison in WA I tried to get some shots of the Wedgetails, with not a lot of success with my modest film camera. My old workmate told me they will eat untill they can hardly fly, and spend the next few days digesting it. He was brought up in Wiluna and so had most of a lifetime to observe them. Planning a trip up that way soon, so might be luckier with todays gear.
