ELA5, CSS, Sferrazza

You pass slowly down the house to the big cage at the end where the touracos now live. The male, Peety, I hand reared while in West Africa. He peers at you from one of the higher perches and then, if you call to him, he will fly down in a graceful swoop, land on the perch nearest to you, and start to peck eagerly at your fingers. Then he will throw back his head, his throat swelling, and give his loud, husky cry: "Caroo...Caroo...Caroo...coo...coo...coo... "

Touracos are really among the most beautiful of birds. Peety's tail and wings are a deep metallic blue, while his breast, head, and neck are a rich green, the feathering so fine and shining that it looks like spun glass. When he flies, you can see the undersides of his wings, which flash a glorious magenta red. This red is caused by a substance in the feathers called turacin, and it is possible to wash it out of the feathers.

If you place a touraco's wing feather in a glass of plain water, presently you will find the water tinged with pink, as though a few crystals of permanganate of potash had been dissolved in it. Having dutifully listened to Peety and his wife sing a duet together, you now make your way out of the bird house.
