Alright, I will start keeping score.
Canon sent it up to their gurus so we will see if they respond?
Thanks all...

Yep, rolling shutter. With hummers I actually prefer a little bit of motion blue. So often those completely frozen hummers look unnatural. I think the pixelation look can be handled in PS.

Check these out, interesting information that is well explained.
Wheter the cause of the "blur" is rolling shutter to just an insufficient speed to freeze the action of the rapidity of a hummingbird's wing movement, the shot is great and natural.
It's like the shots you see of aircraft in flight with the propeller "frozen". I find that disconcerting, especially if I were the pilot or passenger on that airplane or helicopter. A little motion blur can be a good thing!
A Humminbird flaps its wing between 50 and 63 times per second. The tail rotor speed of a Sikorsky Helicopter is Tail Rotor Speed ( at100%) is 1,244 rpm. It would be interesting to do the math and fine which is faster.

The helicopter can fly faster than the hummingbird. Trust me.
You're comparing apples and oranges, units that don't match, so I came up with another interpretation of the question. Sikorsky S-76 178 mph. Hummingbird 61 mph.

WOW! You must like to argue. I was no proposing a race between ad helicopter and a hummingbird. The point I was trying to make was that a bit of motion blur can make an effective picture.
I am not an oenologist- I just enjoy interesting, detailed and well-crafted photographs of birds and all wildlife.
As for helicopters, I know too much about them. I shot reconnaissance imagery and repelled from all kinds of helicopters and gunships in Vietnam. At the time, however, I did not ask the pilots about the specifications of the aircraft. I was just interested in getting the job done and getting the hell away from the targeted area in one piece.
Maybe now, I should go out and buy a radar gun so I can ascertain MPH stats on the pidgins in the l local park- sorry, I'm in Canada, we are metric, it has to be KPH!
Kindest regards!

I was just joking. I agree on the motion blur, but that isn't the same as the rolling shutter effect. It looks like there are two sides in the debate on this picture. Whatever the answer, I don't see the rolling shutter effect as being positive. A picture of the helicopter rotor and blades at high shutter speed would make the blades seem curved. We need global shutters in our cameras.
