About Crimson rosella
The crimson rosella, scientifically known as Platycercus elegans, is a striking parrot native to eastern and southeastern Australia. Its distinctive appearance features predominantly red plumage, complemented by vibrant blue cheeks and blue-margined wings. While adults are known for their brilliant crimson coloration, juveniles often display a greenish-olive body plumage that transitions to red as they mature.
Distribution and Habitat
This species is commonly found in a variety of forest and woodland environments, including mountain forests, tropical, subtropical, and temperate rainforests, as well as wet and dry sclerophyll forests. They are also adaptable to human-modified landscapes such as farmlands, parks, and gardens. Their natural range extends from southeastern South Australia through Tasmania, Victoria, and coastal New South Wales into southeastern Queensland, with a separate population in North Queensland. Introduced populations also exist in New Zealand and Norfolk Island.
Behavior and Diet
Outside of the breeding season, crimson rosellas are social birds, often congregating in pairs or small groups, particularly during feeding. Juveniles are known to gather in larger flocks of up to 20 individuals. During the breeding season, adults become more solitary, foraging only with their mates. Their diet is varied, encompassing fruits, seeds, nectar, berries, and nuts from a wide array of plants, as well as insects and their larvae. They forage both in trees and on the ground.
Breeding and Reproduction
The breeding season typically occurs from September through to February, influenced by rainfall. Nests are established in deep tree hollows, often more than a meter deep, selected by the female. The pair prepares the nest by gnawing and shredding wood debris from the hollow itself. Clutch sizes range from 3 to 8 eggs, which are incubated by the female. Both parents share feeding duties for the nestlings, and young birds reach adult plumage at approximately 16 months of age.
Subspecies and Variations
The species includes several subspecies and forms, notably the nominate race (P. elegans elegans), P. elegans nigrescens, and P. elegans melanoptera. The yellow rosella (P. elegans flaveolus) and the Adelaide rosella are considered subspecies due to their ability to interbreed with the crimson rosella, with the yellow rosella characterized by yellow instead of red plumage and the Adelaide rosella representing a hybrid swarm with varied orange and yellow tones.

Frequently Asked Questions
What is the scientific name of the crimson rosella?
The scientific name of the crimson rosella is Platycercus elegans. This binomial name was established by Johann Friedrich Gmelin in 1788.
What are the main physical characteristics of a crimson rosella?
Adult crimson rosellas are predominantly red with blue cheeks and blue-margined wings. Much of its 36 cm length is its tail. Juveniles, especially in southeastern populations, often display greenish-olive body plumage which gradually transitions to red.
Where does the crimson rosella live naturally?
The crimson rosella is naturally found in eastern and southeastern Australia, ranging from southeastern South Australia through Tasmania, Victoria, and coastal New South Wales into southeastern Queensland. A separate population exists in North Queensland.
What do crimson rosellas eat?
Their diet consists of fruits, seeds, nectar, berries, and nuts from various plants. They also consume insects and their larvae, such as termites, aphids, and caterpillars.
Are there different subspecies or variations of the crimson rosella?
Yes, there are three red-colored races and two other forms that have been reclassified as subspecies: the yellow rosella (Platycercus elegans flaveolus) and the Adelaide rosella. The yellow rosella replaces red areas with light yellow, and the Adelaide rosella is considered a hybrid swarm exhibiting varied plumage.
What is the breeding behavior of the crimson rosella?
Crimson rosellas are monogamous and nest in hollows greater than 1 meter deep in tree trunks or limbs. The breeding season lasts from September to February, with clutches of 3-8 eggs. Both parents feed the nestlings, and young birds reach adult plumage at 16 months.
What are the primary threats to crimson rosellas?
Predators such as the peregrine falcon, grey goshawk, and powerful owl pose threats, as do feral cats and foxes. Interestingly, female crimson rosellas can also be a threat to their own species by destroying eggs in other nests during the breeding season, a behavior thought to be related to competition for nesting sites.
