The Crimson Rosella is a parrot native to eastern and southeastern Australia, which has been introduced to New Zealand and Norfolk Island. It is commonly found in, but not restricted to, mountain forests and gardens. When they forage, they are conspicuous and chatter noisily. Rosellas are monogamous, and during the breeding season, adult birds will not congregate in groups and will only forage with their mate. According to a new study Crimson Rosellas can identify birds of their own subspecies based on the smell of other birds. Source: Wikipedia
