The next topic of discussion is what is a shuttlecock, or sometimes known as the birdie. As you can see, what I'm holding in my hand is your typical feather shuttlecock, which has 16 feathers that supposedly all come from the left wing of either a goose or a duck. The goose feathers are typically much better quality and are used in professional tournaments and advanced level players.
The shuttlecock can also be made of plastic. In both cases, with the feather shuttle and the plastic shuttle, both are attached to a cork base. And that's what a shuttlecock is.
