Crimson Rosella birds

Behavior/Health Concerns:  Some crimson rosellas are prone to obesity, being nippy, and they are also susceptible to bacterial infections and psittacosis. Crimson rosellas are usually housed one pair per cage because they do not make good neighbors with other birds, even of their own species. If breeding crimson rosellas, provide several choices of nesting boxes because they prefer to select their own nest. Once they have chosen a nesting location, the additional boxes may be removed.
