There was a nice film a few years back called Winged Migration which featured incredible footage of wild parrots. Just about everybody's favorite scene in the movie happens about 2:15 into this clip. (The title kind of spoils the surprise, but it's still worth watching.)
To put this scene in perspective, it is illegal to capture a wild Hyacinth Macaw for trade, and they sell for between $7,000 and $12,000 in the U.S.
