I'm guessing that there is nothing smart about the software to avoid this, but 
what I mean is,

If the bird is moving over a stationary landscape, making the images coincide 
at the moving bird will distort the landscape which is not moving; it would be 
impossible for it not to be so.  The landscape is at different positions 
relative to the moving bird so each point be in the same position relative to 
the bird requires some distortion of it.

I saw this with my Madeira panorama.  There were a couple of points that were 
similar and Photoshop blended the images together at one of those points, not 
the other, thereby distorting the sea beneath that point.

Have I explained myself with sufficient clarity and persuasion? :-)  If not, it 
might require diagrams . . .
