Crimson Rosella

About

The Crimson Rosella is a medium-sized parrot native to eastern and south-eastern Australia. Renowned for its striking crimson, blue, and black plumage, it is a common and conspicuous bird in its range, often found in forests, woodlands, and suburban areas. It is primarily a seed and fruit eater, playing an ecological role in seed dispersal.

Physical characteristics

Plumage

Adults are predominantly crimson red on the head, neck, and underparts. The back and wings are black, broadly edged with crimson. The flight feathers are dark blue, and the tail is dark blue with lighter blue outer feathers. The cheek patches are blue. Some subspecies, particularly in coastal areas of South Australia and Kangaroo Island (P. e. flaveolus and P. e. subadelaidae), exhibit yellow or orange coloration instead of crimson, often referred to as 'Yellow Rosella' or 'Adelaide Rosella' respectively, though they are considered subspecies of P. elegans.

Beak shape

Short, stout, and hooked, pale grey to whitish.

Eye color

Dark brown.

Leg color

Greyish-brown.

Distinguishing features

The vivid crimson body contrasting with blue cheek patches and dark blue flight feathers and tail are highly distinctive. The black scalloping on the back and wings is also a key feature.

Juvenile appearance

Juveniles are predominantly dull olive-green on the head, neck, and underparts, with blue cheek patches. The back and wings are black, edged with green. The tail is blue. They gradually acquire adult plumage over 15-18 months, often showing a mottled appearance of green and red during this transition. The full crimson plumage is usually attained by the second year.

Seasonal changes

No significant seasonal plumage changes. Plumage remains consistent year-round, though juveniles undergo a gradual molt to adult coloration.

Sexual dimorphism

Males and females are generally similar in plumage, though males may be slightly larger and have a more intense crimson coloration. Females might have a duller red and sometimes a small amount of green on the nape or underwing coverts, but these differences are subtle and not reliable for field identification.

How to identify

1. 1

   Overall Coloration

   Look for the striking crimson red on the head, neck, and underparts. This is the most defining feature of the nominate subspecies.

2. 2

   Cheek Patches

   Observe the bright blue cheek patches, which contrast sharply with the red head. This distinguishes it from Eastern Rosellas with white cheek patches.

3. 3

   Back and Wings

   Note the black scalloping on the back and wings, where each feather is broadly edged with crimson. Flight feathers and tail are dark blue.

4. 4

   Juvenile Plumage

   If green, look for blue cheek patches and a gradual transition to red/crimson, indicating a juvenile Crimson Rosella rather than an adult of another species.

5. 5

   Vocalization

   Listen for its distinctive melodious, fluting whistle ('klee-wit, klee-wit') or sharp, metallic contact calls ('chit-chit') in flight.

Habitat & range

Biomes

Temperate forests, woodlands, open forests, rainforest edges, riparian vegetation, parks, and gardens.

Geographic range

Eastern and south-eastern Australia, including Queensland, New South Wales, Victoria, and south-eastern South Australia. Also introduced to Norfolk Island and New Zealand.

Elevation range

Sea level up to 2,000 meters (6,500 feet) in mountainous regions.

Preferred environments

Prefers tall eucalypt forests and woodlands, particularly those with a dense understory. Also common in urban parks and gardens with mature trees, especially where food sources like seeds and fruits are abundant.

Behavior

Activity time

Diurnal, most active during the early morning and late afternoon.

Feeding habits

Primarily feeds on seeds of eucalypts, acacias, and grasses, as well as fruits, berries, nectar, and flowers. They also consume insects and their larvae, particularly during breeding season. They forage on the ground, in shrubs, and in the canopy of trees.

Social behavior

Typically seen in pairs or small family groups. Outside the breeding season, they may form larger flocks, especially at abundant food sources or communal roosts. They can be quite bold and accustomed to human presence in suburban areas.

Flight pattern

Flight is strong, undulating, and direct, often accompanied by characteristic calls. They fly with rapid wing beats, often in small groups.

Migration pattern

Generally sedentary, remaining in their breeding territories year-round. Some local movements may occur in response to food availability, particularly in mountainous areas where they may move to lower altitudes during winter.

Territoriality

Pairs are territorial during the breeding season, defending their nesting site. Outside of breeding, they are less territorial and may forage in mixed-species flocks.

Breeding & reproduction

Breeding season

September to February, though timing can vary with rainfall and food availability.

Nesting habits

Nests are typically located in hollows of old eucalypt trees, often high above the ground. They prefer deep hollows in dead or living trees. No nesting material is added other than wood dust or debris already present in the hollow.

Clutch size

3-8 eggs, usually 5-6.

Egg description

Eggs are white, oval, and smooth. Typically 2.8-3.0 cm (1.1-1.2 in) long.

Incubation period

19-21 days, primarily by the female.

Fledging period

Approximately 30-35 days after hatching. Young remain dependent on parents for several weeks after fledging.

Parental care

Both parents feed the young after hatching. The male often feeds the female during incubation and while she is brooding small chicks.

Where to find

Field tips

1. Listen for Calls. Their distinctive fluting whistles and sharp contact calls are often the first indication of their presence, especially when they are hidden in foliage.
2. Look in Tree Canopies. They frequently forage in the upper canopy of eucalypt trees for seeds and nectar. Use binoculars to scan the treetops.
3. Check for Fallen Seeds. Crimson Rosellas also forage on the ground for fallen seeds. Look for them in grassy areas beneath eucalypt trees.
4. Visit Parks Early/Late. They are most active during the cooler parts of the day, early morning and late afternoon, making these the best times for observation in urban settings.

Fun facts

• The 'Yellow Rosella' (P. e. flaveolus) and 'Adelaide Rosella' (P. e. subadelaidae) are color morphs or subspecies of the Crimson Rosella, showcasing remarkable plumage variation within a single species.
• Crimson Rosellas are known to be quite intelligent and can be taught to mimic sounds and words in captivity, though they are not as renowned for this as some other parrot species.
• They play an important ecological role as seed dispersers for various native plants, contributing to forest regeneration.
• Despite their bright coloration, their plumage provides surprisingly good camouflage among the red-barked eucalypts and dappled light of their forest habitats.
