The Shuttlecock

The shuttlecock, usually called the shuttle or bird, weighs about one-sixth of an ounce (more technically about 4 grams or 73 to 85 grains). The official shuttles are made of goose feathers placed in a leather-covered cork head. This is the type of shuttle used in all high-level play. Beginners and school classes often use a cheaper and more durable plastic or nylon shuttle.

When the temperature is high or you are playing at a higher altitude, air is thinner. You will then want a lighter shuttle so that it will fall more slowly. Heavier shuttles are used closer to sea level, in climates with a higher humidity, and for outdoor playing.
