Rufous Hummingbird

Last weekend I visited Lassen Volcanic National Park in northeast California,

and among other things found a swarm of hatch-year Rufous Hummingbirds taking

advantage of the last few flowers of the summer:

Exposure was 1/3000 sec @ f/8 (effective). All comments welcome.

Douglas,

 

That is an amazing photograph! The hummer looks like he's posing for you, after making sure to have his better side towards the camera.

 

While I'm fascinated by the artistry of the shot, I'm puzzled by a technical question. In an exposure of 1/3000 sec., the focal-plane shutter will have a very narrow slit moving in front of the film during the exposure. I don't see any distortion resulting from the combination of the wing moving while the slit is moving. Why isn't that distortion present?
