Why are owl eggs almost perfectly round, while hummingbird eggs look like teeny tiny watermelons? Their conclusion: Egg shape is related to how much time a bird spends in flight, according to a report in Friday’s edition of the journal Science. The software analyzed a total of 13,049 pictures containing 49,175 individual bird eggs. The model showed that, given the right conditions, those forces could produce all of the egg shapes included on the graph. With further research, he said, scientists may be able to narrow down a more specific link between bird anatomy and egg shape.
