Q. I saw a photo of different kinds of bird eggs and noted not only the obvious, that smaller birds lay smaller eggs, but also that some bird eggs are elongate, whereas others are more rounded. What ...

Over the years, scientists have learned about literally thousands of different bird species, and each one sports a distinctive beak shape. But why do bird beaks come in so many different shapes and ...

From the almost perfectly spherical eggs of the brown hawk owl to the pointy eggs of the sandpiper, there is a surprising variety in the shape of bird eggs. Yet why birds lay different shaped eggs has ...

The mystery of why birds’ eggs come in so many shapes has long been up in the air. Now new research suggests adaptations for flight may have helped shape the orbs. Stronger fliers tend to lay more ...

A study found that only a small percentage of bird beak shape variation is dependent on diet, with other factors like display and nest construction probably playing parts too. The shape of the beaks ...

Some of life’s simplest questions get swept under the rug for a long time—after all, the most widespread phenomena often require the most data to understand. Take the shape of the boring egg, for ...

Scientists may have finally discovered a sort of "Grand Unified Hypothesis" that explains what may determine the plethora of diverse egg shapes for all bird species A newly published study indicates ...

For years, scientists have tried to crack a mathematical mystery: Is there an equation that can perfectly describe each and every bird egg? Variable shell shapes complicated things. But it turns out ...

In a finding that could change the way scientists think about bird evolution, researchers have found that the shape of bird wings is influenced more by how closely related species are to one another ...
