Turacin is a naturally occurring red pigment that is 6% copper complexed to uroporphyrin III. Arthur Herbert Church discovered turacin in 1869.
It is found only in the bird family Musophagidae, the turacos. Other birds derive their red coloration from carotenoids (bright and orange-reds) or phaeomelanins (rusty and brownish-reds).
