Budgies are for the most part, really peaceful birds. However, that doesn’t mean that they will not attack when they perceive to be in danger. Violence in budgies is most common during breeding season. Females, for the most part tend to be extremely territorial and will not hesitate to protect their territory or their nesting box. This is seen more when breeding in a colony or aviary. Especially when there are limited nesting boxes or sites available.
Violence in budgies not only occurs between females, in rare occasions male budgies can also become violent. It is mostly observed in males if they feel intimidated or accosted by another male. Fighting for a female’s attention is another reason why males fight. Nonetheless, If you observe this behavior in your own flock, make sure that you are willing and able to intervene. Budgies will fight till death, and trust me when we say it will not be pretty.
We completely discourage colony breeding in budgies. Selective breeding is the best method if you are new to breeding your budgies. This will avoid future headaches and heartaches.
