*Cockatiels are charming and affectionate pets with unique care needs. In the Cockatiel Education Hub, you’ll find information on vocalization, social bonding, nutrition, and creating a safe and engaging environment tailored to your cockatiel’s personality.
Chewy editorial team recommends separating your cockatiels for their safety, especially if aggression has begun to surface.
Cockatiel behavior often shifts during breeding season, so reintroducing the birds later in the year - such as mid summer or winter - could result in better group dynamics when mating instincts naturally subside.
Aggression among cockatiels, particularly during breeding season, is often a response to perceived threats or competition.
For example, a male may act protectively toward a potential mate or become frustrated by the presence of a rival bird. This type of behavior, while instinctual, can lead to displaced aggression and potential injury if not addressed.
Separating the birds or rearranging their social group can help prevent such incidents.
In some cases, trios of cockatiels have coexisted peacefully and even cooperated in nesting activities, but this depends on the individual birds’ compatibility.
Monitoring their interactions closely and adjusting their living arrangements accordingly can help ensure a safe and stable environment.
