The ball of badminton, also known as a shuttlecock, is made from either synthetic nylon or the feathers of a goose or duck, embedded into a rounded cork base. The feathers are usually taken from the left wing of the bird, as this ensures that the shuttlecock does not wobble when it flies and that players have a consistent experience when playing badminton. The shuttlecock is designed to fly through the air in a consistent and predictable manner. Synthetic shuttlecocks are more commonly called badminton birdies, particularly in the USA and Canada, and among casual players.

The birdie is made from cork and 16 feathers, usually from a goose or duck
The "ball" of badminton, known as a shuttlecock, birdie, bird, or shuttle, is made from cork and feathers. The cork base is covered in thin leather, and the feathers are usually goose or duck feathers, although synthetic shuttlecocks made from nylon or plastic are also common, particularly in the US and Canada.
The cork base of a shuttlecock is made from either a whole piece of natural cork or by sandwiching polyurethane between two pieces of cork. The former method is preferable as the shuttlecock's structure is more durable, and the cork changes very little after use. The feathers are embedded into the cork and kept in place with glue. There are typically 16 feathers used, and they are usually plucked from the left wing of a goose or duck, as the feathers from different wings are shaped differently. Using feathers from the same wing ensures the shuttlecock does not wobble when it flies and that players have a consistent experience when playing badminton on different occasions.
The feathers are connected with two layers of string to hold them in place and keep the shuttlecock's form. A dark strip is then placed on the outside of the cork to make it easily visible in flight. A sticker is also usually placed in the middle of the feathers to indicate the brand and type of shuttlecock.
Before play, shuttles are tested to make sure they fly true and at the proper speed, covering the proper distance. Different weights of shuttles are used to compensate for local atmospheric conditions, as both humidity and height above sea level affect shuttle flight.

Feathers are plucked from the left wing only to ensure the birdie doesn't wobble
The "ball" of badminton, also known as a shuttlecock or birdie, is made from cork and either synthetic nylon or feathers from a goose or duck. The cork base is covered in thin leather and the feathers are glued into the cork and bound with two layers of string.
The feathers are plucked from the left wing only to ensure the shuttlecock doesn't wobble when in flight. The angle of the feathers must be consistent for the shuttlecock to fly and rotate correctly. If the feathers are sourced from different wings, the shuttlecock will spin differently. Feathers from the left wing will spin clockwise, while feathers from the right wing will spin counterclockwise. The use of feathers from the same wing also ensures a consistent experience for players.
Dry feathers are brittle and break easily, causing the shuttlecock to wobble. Meanwhile, saturated feathers are too flexible, causing the shuttle to fly too far and fast. Therefore, feathers must be properly humidified to enhance the shuttlecock's speed, durability, and in-flight stability.
Badminton companies have also experimented with synthetic shuttlecocks, which are more affordable and durable than natural feather shuttlecocks. However, synthetic shuttlecocks cannot maintain energy in flight like feathered shuttlecocks, which can still feel dull and heavy even at high speeds.

Feathers are glued and strung together, with a dark strip for visibility
A feathered birdie, also known as a shuttlecock, is made from 16 feathers that are inserted into a cork base and kept in place with glue. The feathers are usually sourced from the left wings of geese or ducks, as feathers from different wings are shaped differently. Using feathers from only one side of the bird ensures that the birdie does not wobble when it flies, providing a consistent experience for players. The angle of the feathers must also be consistent for the shuttlecock to rotate correctly during flight.
To construct the birdie, the feathers are glued together and connected with two layers of string to hold them in place and maintain the shape of the birdie. The feathers are overlapped to form the desired shape. A dark strip is then added to the outside of the cork base to improve the visibility of the birdie during flight.
The cork base of the birdie is typically made from natural cork, which is considered superior to synthetic cork. To make the shuttlecock corks, manufacturers may sandwich polyurethane between two pieces of cork or use a single piece of natural cork. The latter method results in a more durable structure, as the cork maintains its shape better after use.
Before use, feathers must be properly humidified to enhance the shuttle's speed and durability. Dry feathers are brittle and break easily, causing the shuttle to wobble, while saturated feathers become "mushy" and cause the shuttle to fly too far and fast. To ensure optimal performance, shuttles are tested prior to play to check their flight path, speed, and distance.

Synthetic birdies are more durable and common in the US and Canada
The "ball" of badminton, also known as a shuttle, shuttlecock, or birdie, is made of cork and either synthetic nylon or natural duck or goose feathers. The use of the term "birdie" is more common among backyard and beach badminton players in the US and Canada. Synthetic birdies are more durable and affordable than their feathered counterparts. They also require less water to produce as they do not need to be washed, sterilized, and bleached.
Feathered shuttlecocks are considered superior for competitive play due to their flight, control, and feel. The feathers used for these shuttlecocks are sourced from the left wings of geese or ducks to ensure consistent flight and rotation. Feathers from the left wing cause the birdie to spin clockwise when hit, while feathers from the right wing would make it spin counterclockwise. Properly humidified feathers enhance the shuttle's speed change and durability, while dry feathers are brittle and break easily, and saturated feathers cause the shuttle to fly too far and fast.
Synthetic birdies, on the other hand, are more durable and can last longer, making them ideal for beginners and windy conditions. They are also less expensive. However, they do not offer the same level of control and flight as feathered birdies, which is why feathered birdies are the standard for competitive play.
While synthetic birdies are more durable and common among casual players, feathered birdies are preferred for competitive badminton due to their superior performance characteristics.

Feathers must be properly humidified to enhance speed and durability
The feathers of a badminton shuttlecock, or ""birdie", are a crucial element of the game, with the feathers used having a significant impact on the shuttlecock's performance. The feathers must be properly humidified to enhance speed and durability.
Badminton shuttlecocks are traditionally made from the feathers of ducks or geese, specifically the left wing, as the angle of the feathers allows the shuttlecock to fly and rotate correctly. The feathers are plucked from the wings of live birds, a method deemed cruel by animal rights activists. To ensure satisfactory flight properties, feathers from only one wing are used, as feathers from different wings are shaped differently.
The feathers of a shuttlecock play a critical role in its performance, and they must be properly humidified to enhance speed and durability. Dry feathers are brittle and break easily, causing the shuttlecock to wobble during flight. On the other hand, saturated feathers become "mushy", causing the shuttlecock to fly too far and fast. Therefore, maintaining the right humidity level is essential for optimal performance.
To achieve the proper humidity, a humidification box is often used, or a small moist sponge is inserted into the shuttle tube container, ensuring no water contacts the cork. This process ensures the feathers remain flexible, enhancing the shuttlecock's speed and durability. The shuttlecock is then tested prior to play to ensure it meets the required standards for flight speed and distance.
The impact of feather humidification on shuttlecock performance is so significant that it affects the feel of the game for players. A feathered shuttlecock, even when deformed, maintains a constant drag coefficient, resulting in a dull and heavy feel during play. Synthetic shuttlecocks, on the other hand, cannot maintain energy in flight to the same degree, providing a different experience for players.

Frequently asked questions
A badminton birdie, or shuttlecock, is made of a cork base and 16 goose or duck feathers. Synthetic birdies are made from nylon or plastic and have a synthetic cork base.
Feathers are used in a badminton birdie to make it fly through the air in a consistent and predictable manner. The feathers also give the birdie its iconic look.
A badminton birdie works by flipping on impact with a racket so that it always flies cork-first. This flipping motion is due to the birdie's conical shape and the fact that the cork is denser than the feathers, giving it a non-homogeneous mass.
