Abstract
A shuttlecock comprises a tail constructed from a plurality of feathers whose shafts are bound together, a head affixed to the feathers at their quills, and a spring formed from a stack of annular spring plates. Each plate surrounds the feather shafts above the head and is movable along the shafts. A retainer affixed to the feather shafts maintains the spring in a partially compressed state between the retainer and the head. When the head of the shuttlecock is struck, the spring plates produce a springing action and an audible click.
