This is actually a Common Redshank, KK.
Notice the face pattern, and especially the bill length and patterning.
I think the flight shots should confirm this!

You are absolutely correct of course, Mike! 
It was my oversight indeed ...

Cool! Mk 2 seems very good for birding!

Nice photo with a new awesome machine
Just wonder, as the magnifying ratio is smaller at 1.3X for 1D2 than 1.6X for 10D, is there any image quality loss as you have to crop the photo more?

I think you still like the 1.6X for bird shooting,  but like the AF & shutter of markII

Hi KK,
Thank you for sharing your experience on using the new camera.
May be we were too concentrated on our new cameras and I also made a wrong ID of this redshank as a spotted redshank at that moment! 
Here is my photo of the same redshank to share with our BBS members.

Good to see you posting, Forrest! 
Just a note on the Mk II ...
I'm thrilled with its AI Servo AF performance having extensively used Nikon F5, Canon EOS-1v etc previously. I think Canon now truly has a machine with precise AI Servo AF that matches its high speed 8.5 fps. Sharp flight sequence shots are now easily attainable letting the photographer to concentrate on important things such as composition, pose and lighting/exposure.
The 1.3x field of view has its advantage compared with 10D's 1.6x. In fact you can do more aggressive crop and still maintain image quality since you have more pixels in hand with the Mk II.

When mine will be available?!!!?  Nice shot with new tool, KK.

Well, Mk2 has a 8MP sensor so I don't think it could be a problem. Moreover, it can retain AF up to f/8 lens....

The sizes of pixel of the CMOS sensors of 1DII is bigger than 10D.
The sensor size of 10D is 22.7mm x 15.1mm with 6.3million pixels.
The sensor size of 1DII is 28.7mm x 19.1mm with 8.5million pixels.
Hence, to crop out the size of 10D image frame from a photo by 1DII, you have only 5.3 million pixels? Am I right in the calculation?
Of course, the much better AF on 1DII alone is worth the money and saves a lot of priceless shots Bigger pixels have higher low light sensitivity too

The Mk II has pixels of 28.7mm x 19.1mm (APS-H size) CMOS sensor. It measures 8.2um square, similar if not quite, to the 8.8um square pixels of the full frame EOS-1Ds. It also has a new on-chip noise elimination circuit eradicates fixed pattern and random noise etc; far superior than the 10D!
In general pixel size does play an important factor in digital imaging resolution. As expected, pixels of digital compact P&S cameras are substantially smaller resulting in lower image quality ...

 To add a gain of salt to KK's excellent comments: I guess you mix up the physcial size of sensor with resolution. Larger pixel on sensor does not make larger pixels on screen!  To confuse you further, if you crop a 1D Mk.2 image (8.5MP) into a 6.3MP image (which is the resolution of 10D), the result image is still a 6.3 MP image! But to the best of my knowleddge, the result crop will have better quality (if all other factors are identical), because the physical size of individual pixel on 1D Mk.2 sensor is larger.
For detailed treatments, check this:

Have an enjoyable read.

Thanks for the links, Griffin!
All good stuff and fits for bed-time reading ...
Another point I notice using the Mk II is its excellent shadow and highlight rendition which is far beyond that of 10D's capability ...
