Thought I would just add some shots taken with the 7D which I have had for around a week now, and I have to report I have been pretty impressed with it...
Its not a 1D MKIII killer.. but for the money its the closest you will get to 1 series performance without spending twice as much... and 18 million pixels gives you plenty of room to crop, and the high ISO performance is pretty good as well and all in a lightweight small package.
These shots were taken at the Hawk Conservancy Trust here in the UK this afternoon
Those are great shots. How much crop? And what lens? I've had really poor results with BIF and almost any cropping. Image turns soft w/fuzz almost immeditely. I've been using 500 and 300 no extender.

Impulsive component to the read noise in RAW data. In other words, a few pixels that are outliers in the noise distribution. They are particular colors (like red) when it is a red pixel in the CFA that has the noise impulse -- the surrounding G and B pixels aren't as noisy, so you get color saturated noise spikes. White is more likely a spiky G pixel, due to the way demosaic works.
They are all shot with the EF500 F4L most at ISO 400 except for the last one of the Little Owl in flight which is ISO 6400, straight off the camera no noise reduction.
The exif should be intact so you can view shutter speeds etc from that.
No 3 and the last one are about 25% of full frame the others are between 50 & 75% of full frame.

These are what I would expect an 18 megapixel canon to do!

I have seen the white specs in other cameras at high ISO. Not unique to the 7D. You see it in underexposed area of high ISO images.
Photoshop Dust and Scratches cleans it up.
Thanks to Brainiac in a previous post. He demonstrated how well the Photoshop filter Dust and Scratches works.
Thanks. So I guess every sensor is slightly different and I have read about manufacturing process flaws or variation. Either way it appears while mildly irritating this is nothing I should be concerned about. Especially with the sizes I work with. I really do not want to send this unit back.
I'm starting to warm up to it. 70-200 F4 IS IS, ISO 3200, F4, 1/50, FL 200 and with a monopod. Not bad through aquarium glass. Now try to convince me UV filters effect IQ.

I think you and you 7D did pretty well in a tough lighting situation. I like that there's detail on the shadow side of the bird without blowing out a majority of the scene. While I'm guessing that some PP was done, it does indicate some latitude in the images which is good.
Another one just messing around last night in the back of the shop. I took this using Liveview on a tripod with a 2 sec timer, but it doesn't seem as sharp as shooting normally. Maybe its just me but all my Liveview images seem softer.
