Non-Iridescent Feathers
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 Jays and Steller’s Jays.
I wonder if it's true to Zazu, who (in theory) is a red-billed hornbill. The problem is: red-billed hornbills aren't blue. Trumpeter Hornbill can be blue-ish...y but more in an iridescent way, I think. :hmm: Is Zazu a cross-breed? :uhno:
