The macaw would like to have a word with you, r.e. the bold.Like sure, pretty, complimentary colours. Now point me to a bird that has feathers of that EXACT hue of bright orange (and a purple shaft?) and that exact size. I doubt that species would be alive right now as it can't camouflage to save its life.
r.e. the headdress . . . who knows, I'm not an ornithologist. Are you?
Google says with mollusks (for the Mayans, too).Also, PURPLE clothes? How did the Incans dye that? It took chemists centuries to create synthetic purple dyes. Tyrian purple (which is more of a violet than anything) is painstaking to produce. How did the Incans extract purple pigments for their Sapa-Inca rulers, the same Sapa-Inca rulers who were noted to wear RED clothes, hmm?
