Anna's hummingbirds fastest vertebrates for their size

So says New Scientist story about Berkeley hummingbird researcher Chris Clark.
When male Anna's hummingbirds' do courtship flights, they do dives and loops, causing them to sustain accelerations that would leave a human being out cold. (Fighter pilots pass out at 7 g. Anna's hummingbirds can do 10 g).
There's a video with the story, but I can't seem to get it started.
Here's a more detailed take on the story from Not Exactly Rocket Science.
Here's a male Anna's hummingbird I photographed on my street in March.
