Picture a bird egg: Perhaps it’s the cocoa brown of a free-range chicken. Or a robin’s creamy blue-green. If it’s a quail egg, it has inky speckles. Those colors and variations, according to a new ...

New research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch--between about three and six months. The study, led by scientists at ...

The colorful, speckled eggs of modern birds are an innovation inherited from their nonavian dinosaur ancestors. Researchers found no traces of pigment in eggshells belonging to a long-necked ...

If you come across a bird nest there’s usually a pretty good way of telling what kind of feathered friend was responsible for it, even if the bird itself isn’t around. The color, size, and pattern of ...
