Structural Colors
Adding to the diversity of avian colors are colors produced by the structure of the feather. The best known example is the gorget (throat feathers) of many hummingbird species. The iridescent colors of the gorget are the result of the refraction of incident light caused by the microscopic structure of the feathers. The refraction works like a prism, splitting the light into rich, component colors. At certain angles little or no light is reflected back to the viewer and the gorget can appear black. As the viewing angle changes, the refracted light becomes visible in a glowing, shimmering iridescent display.


Not all structural colors are iridescent. Tiny air pockets in the barbs of feathers can scatter incoming light, resulting in a specific, non-iridescent color. Blue colors in feathers are almost always produced in this manner. Examples include the blue feathers of bluebirds, Indigo Buntings, Blue Jay's and Steller's Jays.

The feather structures of many species also reflect light in the ultraviolet range. Some birds can see into the UV range so they may appear quite different to each other than they do to us.

Ciao Tom, great capture of lovely bird in nice pose on beautiful blurry BG, fantastic metallic colors, fine details and splendid sharpness, very well done, my friend, have a good week end, ciao Silvio

Hello Tom,
This is one amazing photograph. This bird, depending on the sun/light sometimes appears black. It is only when you catch the sun's rays on it's fantastic plumage that you get an exposure like this. I love that yellow eye. perfect POV abd BG. Great work my friend.
Best regards,
Carl
