Charting bird egg shapes, and why so many varieties

Posted to Infographics  |  Tags: ,  |  Nathan Yau

Bird eggs come in all shapes and sizes, and people didn’t really know why. After analyzing a number of variables, researchers think they found their answer.

After crunching the numbers, the scientists found the links they’d been looking for: the length of an egg correlates with bird body size. The shape of an egg—how asymmetrical or elliptical it is—relates to flying habits. And the stronger a bird’s flight, the more asymmetrical or elliptical its eggs will be.

Lots of charts and probably more information about bird eggs than you ever thought you wanted to know.
