Definition
Sickle feathers are long, curved feathers found in the tails of some male birds, especially those in the Galliformes order (like chickens and peacocks) 🐔. They are ornamental feathers used for display during courtship rituals. These feathers often have a distinctive, iridescent sheen, catching the light and attracting attention. Think of them as the bird's equivalent of a fancy sports car 🚗. Sickle feathers are a prime example of sexual selection in action.
