The frame of the high quality shuttlecock is actually 16 goose feathers secured in the cork and tide with thread. More commercial shuttlecocks use nylon mesh in place of the goose feathers.
The cork at the bottom of the shuttlecock is heavier, which helps stabilize its flight when it is hit upwards. When the shuttlecock starts to descend after being hit, the heavier cork naturally stays at the bottom due to gravity, providing a stable base for the feathers to slow down the descent and keep the flight consistent.
