I understand what you mean now that you've used distortion rather than
compression. However, I don't think the software operates as you
surmise. I probably took at least a minute and maybe even two minutes
making the images that comprise the pano. During that time the bird was
all over the place but always somewhere within the view that I was
making. It's clear to me that the software recognized that this was a
single moving object, chose one and deleted the others. Had it tried to
make all the bird's positions fit one the final image would have been a
distorted mess. It's not. It may be the best pano I took in Scotland.
Now that I look at it again I see there are two birds. Could be the
same one but I don't think so. In any case he was flying around over
enough area that he could have appeared in most of the 9 images that
make up this pano. You can see it here... it's Loch Fyne:

Clicking on the one image gets you a really big one.
