something else to consider is that heat haze has much more effect than you
would guess from what you can see through the viewfinder. i figure that the
working range of my setup of a 400/2.8 with the 1.7X extender is really only
up to about 500ft. much more than that on a warm day and air currents become
too much for good sharpness. i prefer to work at no more than 200 ft if i
can help it. for small bird work, i prefer 30-40ft.

I didn't give that much thought. I could have gained a half stop of
shutter speed, which might have tightened things up a bit more.
I made a print of the shot of the geeses around the radar tower today at
work. It looks a tad over sharpened, but some of that may be from the heat
haze from the tarmac. The white cheeks on the geese are visible in the
4x6, which was nice.
