Larry, I try to capture a scene or incident without worrying too much
about technical perfection. If I did, I would simply "miss" so many
opportunities. It distresses me that I mostly seem to be so far from the
action but that's just how it is. The Sigma does very well when the
subject is closer. I had a Makinon 500mm f8 Mirror Lens from film days
which worked OK but prefer.the versatility of a Zoom. I gave the Makinon
to my daughter which she uses successfully on her C*non with an adapter.

That really is pushing the limits, but still a very cool photo.

Just for interest, a heavily cropped shot of a Saddlebilled Stork with Impalas
on the W bank of Sable Dam, Kruger Park, about 300m distant. Adult Saddlebilled
Storks are about 1.5m tall with a wingspan of 2.5m. This is probably a bit
beyond the useful limit of a Sigma 170-500 DG on a K5. A D-FA 150-450 with a
1.4x TC (630mm) or an FA 600 would do better but such beasts are way beyond my
budget.
I think that there are supposed to be some relatively inexpensive 1000mm manual
focus reflector lenses. I wonder if enough of your photography is such that
you could set one of those up on a tripod. It looks like that in a lot of your
photos the animals aren’t moving around all that much, even if they are at a
great distance.
