Every bird creates its eggs in a stretchy tube called

How do you make an egg shape?

draw the two diagonal lines from the points where
the half-circle touches the horizontal line, both through the same point on the vertical line (the shape of the egg depends on the point you choose for this purpose).
What determines the shape of an egg?
“We showed that egg shapes vary smoothly across species, that it is determined by
the membrane properties rather than the shell
, and finally that there is a strong correlation linking birds that have eggs that are elliptical and asymmetric with a strong flight ability, the last a real surprise.”
Why are eggs oval in shape?
This means the ‘more-oval’ eggs of these cliff-nesting birds will roll in a very tight little circle, and be less likely to roll out of the nest — and off the cliff. Another reason for eggs to be egg-shaped is

.
