My male bird killed my female bird. What caused this aggression?

Updated On September 23rd, 2025

Pet's info: Bird | Unknown - Bird | Female | unspayed | 9 years old

I have a question about my birds (Rosellas). I had a couple; a male and a female parrot for 8 years +, they've never mated. He was always feeding her but she did not want him to mate with her. He always got aggresive and pulled out her feathers... we seperated them once but after half a year put them back together as male bird seemed very weak and lonely. Yesterday my dad saw lots of feather on the ground and he checked up the cage and seen a female bird was dead. Theres blood on a male.

I'm sorry to hear about the loss of your bird. It is possible the male became frustrated, or there was competition over shared resources such as food, water, bedding, etc, that led to a fight and the death of your female if it appears she was attacked by the male. Making sure birds have enough space to move around and access food and water safely is always needed, as well as slow introductions when two birds haven't been together before or in a long time. It would probably be best not to introduce another bird to your male, and to instead focus on enrichment in other ways such as adding in puzzle toys, treats, fun things to interact with, etc, instead of adding a new bird that may stress him out or cause competition.
