Crimson Rosella

The Crimson Rosella (Platycercus elegans) is a medium-sized parrot, measuring approximately 36 cm in length, a significant portion of which is comprised of its tail. This species exhibits a vibrant plumage predominantly of crimson with blue cheeks and black-scalloped blue-margined wings. The tail is primarily blue with red undertones. The bill is a pale grey, and the eyes are a dark brown. There is minimal sexual dimorphism, though males can be up to 15% larger with a more substantial beak.

Identification Tips

Adult Crimson Rosellas are predominantly red with blue cheeks and black-edged wings. Juveniles, however, display a greenish-olive body that gradually 'ripens' to red as they mature. The species is known for its striking blue tail feathers, which are often sought after by the Satin Bowerbird for decoration.

Habitat

Crimson Rosellas are found in a variety of forested habitats, including tropical, subtropical, and temperate rainforests, as well as wet and dry sclerophyll forests and woodlands. They are also comfortable in human-modified landscapes such as parks and gardens.

Distribution

Native to eastern and southeastern Australia, the Crimson Rosella has also been introduced to New Zealand and Norfolk Island. In Australia, their range extends from southeastern South Australia, through Tasmania and Victoria, to coastal New South Wales and southeastern Queensland.

Behaviour

These birds are generally sedentary, with some populations displaying nomadic tendencies. They are not migratory. Crimson Rosellas are monogamous and form pairs or small groups, especially outside the breeding season. They are known for their noisy chattering while foraging.

Breeding

Crimson Rosellas nest in tree hollows, with the breeding season spanning from September to February. They lay clutches of 3-8 white, slightly shiny eggs. Only the female incubates the eggs, which hatch after about 19 days. The young fledge and become independent by February.

Diet and Feeding

Crimson Rosellas feed on a variety of fruits, seeds, nectar, berries, and nuts, as well as insects and their larvae. They are known to cause damage to crops, which historically led to conflict with farmers.

Conservation status

The Crimson Rosella is listed as Least Concern on the IUCN Red List. However, they face predation from birds of prey, feral cats, and foxes. Surprisingly, the most significant threat to their eggs comes from other Crimson Rosellas during the breeding season.
