When Do Cockatiels Go Through Puberty? Everything You Need to Know!

Puberty is a period of development during which birds reach sexual maturity. During this period, hormones are released, causing physical and behavioral changes. In cockatiels, puberty usually occurs when they reach sexual maturity, which is around 6 to 9 months of age. However, the age of puberty in cockatiels can vary depending on various factors.

Age of Puberty

The age at which cockatiels go through puberty can vary depending on several factors such as genetics, diet, and environment. For example, cockatiels that are well-fed and have plenty of space to move around will reach sexual maturity faster than those that are malnourished and kept in cramped spaces.

Factors Affecting Puberty in Cockatiels

Diet and nutrition are essential factors that affect the onset of puberty in cockatiels. A balanced diet that provides all the necessary nutrients is crucial for the healthy development of a cockatiel. Feeding them with a diet that is high in fat and low in nutrition can delay the onset of puberty.

The environment also plays a vital role in the development of cockatiels. Providing them with enough space to move around and play can help in the healthy development of their muscles and bones. On the other hand, keeping them in cramped spaces can cause stunted growth and delayed puberty.

Physical and Behavioral Changes

Physical Changes During Cockatiel Puberty

During puberty, cockatiels undergo several physical changes. One of the most noticeable changes is the development of their sexual organs. Male cockatiels will develop a bright yellow face and orange cheeks, while females will become more prominent and plumper. Additionally, both males and females will have a change in their plumage. Male cockatiels will have brighter and more striking colors, while females will have a more subdued and plain appearance.

Behavioral Changes During Cockatiel Puberty

Cockatiels will also undergo behavioral changes during puberty. They will become more vocal and may begin to mimic sounds and words they hear regularly. Additionally, they may become more aggressive, territorial, and possessive of their food and toys. Some cockatiels may also start to exhibit nesting behavior, such as shredding paper or fabric to make a nest.

Common Problems during Puberty

Aggression and Vocalization

One of the most common problems during cockatiel puberty is aggression. Cockatiels may become more territorial and possessive, leading to aggression towards other birds or even humans. Additionally, they may become more vocal and start to scream and screech excessively. These behaviors can be challenging to deal with, but there are ways to mitigate them.

Nesting Behavior

Another common problem during cockatiel puberty is nesting behavior. Cockatiels may start to exhibit nesting behavior by shredding papers, fabric, or other materials to make a nest. Although this behavior is natural, it can be destructive and messy. Providing them with a nest box can help redirect this behavior.

How to Deal with Puberty Changes

Provide Adequate Space

Providing cockatiels with enough space to move around and play can help reduce aggression and other behavioral problems during puberty. A large cage or aviary with plenty of toys and perches can help keep them occupied and happy.

Adjusting Diet and Nutrition

Adjusting the diet and nutrition of cockatiels is essential during puberty. Providing them with a balanced diet that is high in nutrition and low in fat can help in the healthy development of their bodies. Additionally, providing them with fresh fruits and vegetables can help reduce boredom and keep them occupied.

Training and Socialization

Training and socialization are crucial during puberty. Cockatiels that are well-trained and socialized will be less likely to exhibit aggressive behavior and other problems during puberty. Spending time with them and providing them with regular training and socialization can help reduce the negative effects of puberty.


In conclusion, cockatiel puberty is a natural and essential phase of development that all cockatiels go through. Understanding the physical and behavioral changes that occur during this phase can help owners prepare and deal with any potential problems. Providing cockatiels with adequate space, nutrition, and training can help mitigate the negative effects of puberty and ensure that they grow into healthy and happy birds.
