How do iridescent feathers work?

As iridescent birds move, nanoscale structures within their feathers’ tiny branch-like filaments — known as barbules — interact with light to amplify certain wavelengths depending on the viewing angle. This iridescence is known as structural coloration, wherein crystal-like nanostructures manipulate light.

Do peacock feathers have pigment?

Detail of a peacock feather. Pigment particles are embedded into the newly grown feathers during the molting season. They absorb light of certain wavelengths, or disperse the reflected light, and so contribute to the color of the plumage. Colors due to pigments are explained in the section about organic pigments.

Are peacock feathers really brown?

Are peacock feathers actually blue?

For example, peacock tail feathers are pigmented brown, but their microscopic structure makes them also reflect blue, turquoise, and green light, and they are often iridescent.

Are blue feathers really blue?

“Blue is different―no bird species can make blue from pigments. The color blue that we see on a bird is created by the way light waves interact with the feathers and their arrangement of protein molecules, called keratin. In other words, blue is a structural color.

Why is blue so rare in nature?

So why is that? Part of the reason is that there isn’t really a true blue colour or pigment in nature and both plants and animals have to perform tricks of the light to appear blue. For plants, blue is achieved by mixing naturally occurring pigments, very much as an artist would mix colours.

What does finding a blue jay feather mean?

Some people believe that blue jay feathers symbolize light and joy. Looking at them fills the heart with happiness and warmth. The feathers of these native American birds are symbolic of luck and fortune. It is believed that if you see a bluejay, you will find luck and be able to fulfill your dreams.

What is the difference between pearlescent and iridescent?

*The difference between pearlescent and iridescent: pearlescent is pearl-like in either color or luster, while iridescence produces a display of lustrous, prismatic and rainbow-like colors.

Is iridescent meat safe to eat?

Even though iridescence is a natural occurring factor, and does not effect the quality or the palatability of the meat, it is not acceptable to the consumer, and the consumer perceives the iridescent colors as spoilage, primarily because of the greenish hues.
