C1Technical/Specialized
Definition
Meaning
The set of large, showy feathers at the rear of a bird's tail, which can be spread out in a fan shape.
A term from ornithology describing the specialized tail structure, particularly of birds like peacocks, turkeys, or pheasants, used for display, balance, and sometimes flight control. By extension, can refer to any similar fan-shaped arrangement at the rear of an object or animal (e.g., certain fish, aircraft components).
