The flattened shape and air bubbles of hummingbird melanosomes create a more complex set of surfaces.

How do hummingbirds use wavelengths?
The makeup of the hummingbird enables it to fully use the wavelengths to appear as if it is changing color . Iridescent feathers have layers of air bubbles on the surface which results in the light not staying there when it hits the surface, as it would do with regular feathers. This results in some of the light reaching the surface of the feather and some reflecting back off the bubbles. Some wavelengths travel through the bubbles to the inner surface of the feather, some travel through one layer of bubbles to the layer underneath. This intense combination of reflection and refraction results in light traveling in different directions. These light rays can also cross and combine.

Thanks to refraction, the bending of sunlight, the gorget will glisten when sunlight hits it.

What are the morphology of birds?
In understanding the morphology of birds, one must understand the feathers. Feathers are a unique characteristic to birds and their dinosaur ancestors and are important in insulation, thermoregulation, and flight. The birds' feathers are made up of keratin -- the material that comprises the mammalian hair and nails -- and they are arranged like trees complete with parts resembling the trunk, branches, and leaves. The leaf-like structures are the barbules, these are the cells that contain melanosomes or the pigment-containing organelles. The melanosomes and its shape and arrangement can influence how light bounces off the feather, eventually producing bright colors. Co-author Matthew Shawkey from the University of Ghent in Belgium explains that they call the iridescent color produced as structural colors because they depend on the structural dimensions. "A good analogy would be like a soap bubble." He narrates. "If you just look at a little bit of soap, it's colorless. But if you structure it the right way, spread it out thinly to form the bubble, you'll get the shimmering rainbow colors around the edges."
