Sandy, like all good research, it keeps the "conversations" on this (and 
other) topics lively.

[Sandy Podulka]

I'm having a lot of trouble believing this. Many birds need to fly 
well, and it's hard to believe all (or most) eggs wouldn't be the 
best shape for flying, in general, if this were true.  I can't 
believe the flying needs of albatrosses and sandpipers, both of which 
fly long distances, are so different that they would produce such 
different shapes. And some owls migrate (saw-whet), whereas others do 
not (Eastern Screech-Owl), yet their eggs are a similar shape, quite 
spherical.  Why? They both nest in holes.  I still like the older 
theories. But maybe that's because I'm old.
