Shreeni, indeed there is something odd going on with those pictures, almost as if they are suffering from a major haze/flare.
Now, a few observations up front, before I make my suggestion.
(1) The little birds coming to your feeder are better shot with a higher/safer shutter speed such as 1/1000-1/2000 sec. That way you also have a chance of catching them in flight.
(2) The Sandhill cranes are overexposed by a lot.
(3) Have you mounted the hood on the lenses when you took those shots ?
Now, I have a following suggestion for testing your 5DMkIII.
(1) Shoot JPG only, Standard picture style, set sharpening to 5, everything else to 0.
(2) Turn off all auto features such as auto ISO, Highlite priority, exposure bracketing, multiple exposures, safety shift and whatever else might be there.
(3) Set camera to AV mode, partial metering, center AF point w/o expansion, one shot AF, shoot at f/4.
(4) Have your 300 f/4 on the camera.
(3) The test target is 3 popcans, 10-15 ft distant, and well lit, but no strong back/sidelight. The popcans are staggered by 1/2 inch, ie., the left can is 1/2 inch behind the centre can, and the right can is 1/2 inch in front of the centre can.
(4) Do at least a dozen or so shots of the centre can. Defocus the lens between individual shots. Make sure that you\'ve got ample shutter speed for the type of support.
(5) Do not do any JPG postprocessing, evaluate JPGS SOOC.
