Thread title should say "... in focal length limited situations" A very serious omission in my opinion.
He could have said it more explicitly, but it is good that he went there. Too many people seem to think that bigger sensors and/or bigger pixels are analogous to "bigger antennas" picking up more signal, but that is not necessarily the case.
I am bird photographer too and I am excited about the 7DII. Currently I shoot wildlife primarily with my 70D as opposed to my 5DIII because the 1.6x crop factor helps me in those focal length limited situations
The crop factor may affect the magnification in the viewfinder, but it is not responsible for the greater maximum detail of your subject in the capture; that is due to the pixel density alone.
(basically shooting the same distant bird with both cameras from the same spot.). Yes, if I upscale the 5DIII image to match the subject (bird) size of the 70D image, sharpness suffers and noise increases. Simple physics.
But, without the right context, the title statement is not true. Only in focal length limited scenarios.
For some people, that is 99% of their photographic world, and very relevant. Perhaps we should create an acronym, "FLLP" for focal-length-limited photography, so people are more likely to mention it. Spelled out, it is a lot of work. Also, DxOMark should have something like "Surface" in addition to "Screen" and "Print", describing the measured noise qualities of the sensor surface, for those choosing cameras to use with FLLP.
