Mysterious Structures in Deltarune Chapter 5 require a special power to activate. Here's how to get the Petal Feather and ...

(PhysOrg.com) -- Some of the brightest colors in nature are created by tiny nanostructures with a structure similar to beer foam or a sponge, according to Yale University researchers. Now an ...

The microscopic structure of the feathers of the eastern bluebird, a type of North American thrush, has inspired the creation of a simple-to-produce, scalable and robust novel synthetic material that ...

Biologists provide evidence that maximum body size in birds is constrained by the amount of time it takes to replace the flight feathers during molt. Why aren't birds larger? Fifteen-kilogram swans ...

Peacocks, perhaps nature's most trippy bird, shake their tail feathers when it's time to attract a new mate. Why? Shaking those feathers — called "train-rattling" — causes an illusion where the ...

The color of some feathers on dinosaurs and early birds has been identified for the first time. The research found that the theropod dinosaur Sinosauropteryx had simple bristles -- precursors of ...

The researchers found an evolutionary tweak in feather nanostructure that has more than doubled the range of iridescent colors birds can display. This insight could help researchers understand how and ...

A study explores how birds rearrange feathers after flights through gusts and foliage. The durability of bird feathers is evident in the ease with which birds preen and repair ruffled feathers using ...

Blackbirds, it turns out, aren’t actually all that black. Their feathers absorb most of the visible light that hits them, but still reflect between 3 and 5 percent of it. For really black plumage, you ...

Some of the brightest colors in nature are created by tiny nanostructures with a structure similar to beer foam or a sponge, according to Yale University researchers. Most colors in nature—from the ...
