Goura is a dainty, graceful feather very effective when used in quantity, but very expensive. The cause of its high cost is easily understood when you see the tiny spray which grows on the topknot of the goura bird.

Numidy feathers have a straight stem and a very long, dropping fiber.
Usually they are used in clusters and in a standing trim like aigrettes. They are an African importation. Coq in black, in iridescent shades, and in colors, is used to trim many smart hats. Spanish coq feathers are iridescent, long and curved. They are the tail feathers of the Spanish rooster.
