Scientists hypothesize that since the tapered end provides more surface area for the muscles to act on, it helps birds to squeeze the egg out easily.

This asymmetric shape also allows the eggs to fit tightly together, keeping them warm.

Also, if the egg is nudged, it will roll in a circle and probably stay in the nest. A spherical egg would roll straight and fall off.
