Why Are My Cockatiels Fighting? Tips to Help Them Get Along

Cockatiels have a social hierarchy, with dominant birds at the top and subordinate birds at the bottom. Dominant birds have priority access to resources like food, water, and perches. Subordinate birds must wait their turn or find other resources. This hierarchy can change over time as birds vie for dominance.

Cockatiel Communication

Cockatiels communicate with each other through body language, vocalizations, and behaviors. Some common behaviors include head-bobbing, tail-flicking, and wing-flapping. Cockatiels use these behaviors to establish dominance, attract mates, and warn others of potential threats.

Reasons Why Cockatiels Fight

There are several reasons why cockatiels may fight with each other. Understanding these reasons can help you prevent and resolve conflicts.

Competition for Resources

One of the primary reasons why cockatiels fight is competition for resources. If there is not enough food, water, or perches to go around, birds may become aggressive and fight with each other. This is especially true if there are more birds than resources.

Protecting Territory

Cockatiels are territorial and may become aggressive if they feel like their space is being invaded. This can happen if a new bird is introduced to the flock or if birds are moved to a new cage or location.

Establishing Dominance

As mentioned earlier, cockatiels have a social hierarchy. Birds may fight to establish dominance over each other and move up the hierarchy. This is especially true if there are new birds in the flock or if the hierarchy is changing.

Mating Behaviors

Cockatiels may also fight during mating behaviors. Male birds may fight over a female or territory, which can lead to aggressive behavior.

Signs of Aggression and Fighting

It is important to be able to recognize signs of aggression and fighting in cockatiels. This can help you intervene and prevent serious conflicts.

Physical Indicators

Physical indicators of aggression and fighting include birds biting, flapping wings aggressively, and chasing each other around the cage. Birds may also puff up their feathers and lunge at each other.

Verbal Indicators

Verbal indicators of aggression and fighting include birds hissing, screeching, and making other loud vocalizations. Birds may also engage in beak-clicking as a warning sign.

Steps to Help Cockatiels Get Along

If your cockatiels are fighting, there are several steps you can take to help them get along.

Provide Sufficient Cage Space

One of the most important things you can do is provide enough cage space for your birds. A crowded cage can lead to fighting and aggression. As a general rule, each bird should have at least 3-4 square feet of space.

Give Equal Access to Resources

Make sure that each bird has equal access to resources like food, water, and perches. Consider adding extra resources if you have multiple birds.

Provide Adequate Toys and Enrichment

Cockatiels are intelligent and curious birds that need mental stimulation. Provide plenty of toys and enrichment activities to keep them occupied and prevent boredom.

Gradual Introduction to Each Other

If you are introducing a new bird to the flock, do so gradually. Start by keeping the birds in separate cages near each other so they can get used to each other’s presence. Then, gradually introduce them under close supervision.

Separating Aggressive Birds

If birds are fighting and becoming aggressive, it may be necessary to separate them. Move the aggressive bird to a separate cage for a few days or until the behavior improves.


Cockatiels are social animals that need companionship to thrive. If your birds are fighting, it can be stressful for both you and them. By understanding their behavior and providing enough space and resources, you can help your cockatiels get along and live happy, healthy lives together. Remember to monitor your birds closely and intervene if necessary to prevent serious conflicts.
