Birds’ eggs exhibit a surprisingly narrow palette of natural pigments, yet they produce a stunning variety of colors and patterns. Nearly all the hues seen on bird eggshells come from just two pigments. Here is an exploration of the science behind the pigments of bird eggs and the artist-grade colors that best match them, complete with examples and mixing tips.
The story of the elephant bird’s egg weaves together biology and paleontology, myth and history, and cutting-edge science. It is a tale that spans continents and centuries, from ancient Indian Ocean legends of giant birds, to modern museum displays and DNA laboratories. Here is the tale of an egg as big as a basketball, holding secrets of the past.
The egg of the Dodo remains one of the most enigmatic and least documented aspects of this extinct bird’s biology. In this article we compile available evidence from historical texts, museum records, and scientific studies to reconstruct the most accurate portrait possible of the dodo’s egg and its role in the bird’s life history.
The egg, an ancient and essential form of life, has fascinated naturalists, artists, and scientists for centuries. Among vertebrates, birds produce the most visually and structurally diverse eggs, ranging from nearly perfect spheres to sharply pointed ellipsoids. But why are bird eggs shaped the way they are? What evolutionary forces molded their geometry? And what physical processes produce such shapes inside the bird’s body?
Reconstructing the size, shape, surface texture, and coloration of extinct Mesozoic bird eggs is challenging because actual egg specimens from Mesozoic birds are extremely rare. Paleontologists must rely on indirect, non-destructive methods to infer these characteristics for museum displays and scientific understanding. Here we outline key non-invasive methods and their applications, with examples from recent scientific literature.
Bird eggs exhibit a remarkable variety of colors and patterns, ranging from plain white to vibrant blue-green or speckled brown. In this paper, we examine the pigments responsible for egg colors, the process of pigment deposition during egg formation, the biological purposes of colored eggs, variations across species and environments, and the influences of diet, health, and genetics on egg color.
