Great blue turaco
Corythaeola cristata

— Where the name comes from
Corythaeola comes from the Greek kórys, the helmet, for the stiff black crest it carries; cristata says the same thing again in Latin. The order is called Musophagiformes, “banana-eaters”, after an old and mistaken conviction: turacos do eat fruit, but hardly ever bananas, and the name survives out of nineteenth-century inertia.

— What sets it apart
Turacos possess two pigments that exist in no other animal in the world: turacin, which is red and contains copper, and turacoverdin, which is green. It is very nearly unique — in the rest of the birds, green and blue arise from the microscopic structure of the feather and from light, not from a dye. Because turacin is soluble, it was said in the nineteenth century that turacos ran in the rain; that is an exaggeration, but the substance really is fragile enough to leave traces in the water the bird bathes in.
