A shuttlecock, also known as a birdie, is a projectile used in the sport of badminton. It consists of a conical arrangement of feathers or a synthetic material attached to a cork base. The design allows it to fly in a stable, predictable manner, making it suitable for the fast-paced nature of the game. Shuttlecocks come in various types, with differences in weight and material affecting their flight characteristics. The most common type is made with 16 feathers, but there are also synthetic options for recreational play. Players aim to hit the shuttlecock over a net, scoring points by landing it in the opponent's court.
