Mixing several bird species in the same aviary: mistakes to avoid
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Mixing several bird species in the same aviary isn't a problem in itself, but the most common mistake is underestimating the space needed and the breeding season, two factors that turn a peaceful cohabitation into repeated attacks. Our other habitat pointers are in the bird bedding and habitat section.

Why does aviary size change everything?
The smaller the space, the more competition for perches, feeders and resting spots drives stress and territorial aggression. An aviary designed for a single species quickly becomes a battleground once more residents are added without expanding the available area, as noted for the minimum space for a macaw aviary.
What's the mistake around breeding season?
Species that cohabit without issue the rest of the year can turn genuinely aggressive once a pair enters breeding mode and starts defending its nest. This pattern is well documented among parakeets and rosellas in particular, where breeding pairs attack other aviary occupants regardless of species. A recent Delphi consultation with companion parrot welfare experts stresses just how important it is to monitor social stress indicators within a shared space.
Which species should you avoid mixing?
- Large parrots (African greys, Amazons) with small parakeets: risk of serious injury in a conflict
- Highly territorial species (rosellas, lovebirds) with each other in a small space
- Adult birds of unknown temperament introduced abruptly, with no observation period
How do you limit the risks if you do try mixing species?
Favour species of similar size, introduced young rather than as adults, in a spacious aviary offering several retreat zones. Add extra feeding stations and perches to reduce competition, and remove any nest box or breeding prop if tension appears during the nesting period.
Frequently asked questions
Can you put two birds back together after a fight?
Be cautious: separate them first, work out what caused the conflict, and only retry cohabitation in a larger space with close supervision.
Do injuries between aviary birds need a vet?
Yes, always, even superficial ones: a wound around the beak or legs infects quickly in a bird.
Can a cockatoo live with budgerigars?
It's risky: the difference in strength and size makes any dispute potentially fatal for the budgerigar, so separate aviaries are safer.
