How to recognise a northern rosella?

General appearance

The Northern Rosella is a medium-sized parrot, around 28cm long. It has a black head and neck with a blue patch behind the eye, and white cheek patches. The back and wing coverts are black with yellow borders creating a scalloped pattern. And, its belly is red and blue with black edges.

Male vs female

Gender differences in Northern Rosellas are subtle. Males are typically slightly larger with a bigger beak. The blue patch on the nape is more spread out in males while more concentrated in females. Colors might also be slightly brighter in males, but this is not a reliable indicator.

Juvenile

Juvenile Northern Rosellas have a lot of green on them, particularly on the back and wings, which slowly changes to black as they mature. They also have a smaller beak and their cheek patches are more cream than white. The change from juvenile to adult plumage usually occurs at around one year old.

Size

11.4 - 12.6 in/3.2 - 3.9 oz

Habitat

Primary habitat

The Northern Rosella's preferred habitats are tropical and subtropical woodlands. They typically inhabit the northern regions of Australia, including the top parts of Northern Territory and northwestern parts of Queensland.

Additional range

Though these birds favor warmer climates, they also adapt to urban areas and farmlands, taking advantage of any lightly wooded areas or parks. They rarely occur in areas of intensive agriculture or dense forest.

What do northern rosellas like to eat?

Natural diet

The northern rosella primarily feeds on seeds, fruits, berries, and flowers. It forages on the ground and in trees, consuming grass seeds like those from spinifex and other native plants. Insects and their larvae also form a part of their diet, providing essential proteins. The bird is known to feed on eucalyptus nectar as well, playing a role in pollination.

Bird feeders

At bird feeders, northern rosellas generally eat a variety of seeds, including sunflower and millet. They might also consume commercial parrot mixes which can contain grains and dried fruits. Providing fresh vegetables like carrots or leafy greens can attract them as well, although seeds tend to be the main attraction for these birds.

What does a northern rosella sound like?

The Northern Rosella is known for its distinct, melodious vocalizations. Its typical calls involve a series of quickly repeated, high-pitched notes, described as ‘pi-pi-pi’, often with a metallic tone. These calls can range from thin and sharp to a more twittering sound, given while the bird is in flight or perched. Unlike other parrot species, the Northern Rosella does not have a very broad range of songs, with its vocal repertoire largely limited to variations of its primary calls. Its calls often carry over long distances, signaling its presence in its native Australian habitats.

Also known as: Tasmanian Rosella

How to recognise a green rosella?

General appearance

The Green Rosella, or Tasmanian Rosella, possess a unique coloration that is primarily green, with patches of blue on the head and wings. It also has a conspicuous yellowish stomach. With a size up to 37 cm, they are considered the largest rosella species. They have round bodies, broad tails and strong beaks, equipping them perfectly for their native environment in Tasmania and Bass Strait islands.

Male vs female

Sexual dimorphism is difficult to detect in Green Rosellas. Both genders share the same coloration. However, adult males tend to be slightly larger in size and possess a larger beak compared to females. Due to these slight variations, an experienced breeder or a DNA test is usually needed to determine gender accurately.

Juvenile

Juvenile Green Rosellas have a more muted coloration compared to adults, their green color is less vibrant and they lack the yellow belly. Furthermore, their beaks are initially more orange compared to the whitish color seen in adults. As they mature, they gradually acquire the distinctive adult coloration. Their full colouring, size, and gender traits will be fully recognisable after 12-18 months.

Size

11.4 - 14.2 in/3.2 - 5.8 oz

Habitat

Primary habitat

The green rosella primarily inhabits Tasmania and surrounding islands. Its preferred habitat includes rainforests, woodlands, and shrublands.

Additional range

The green rosella has adapted to a variety of climates and can also be found in unexpected environments, such as suburban gardens and farmlands.

What do green rosellas like to eat?

Natural diet

The green rosella primarily feeds on native seeds, fruits, flowers, berries, and insects. Common natural food sources include eucalyptus seeds, acacia seeds, and a variety of native fruits like those from the cherry ballart and native laurels. It uses its strong beak to extract seeds from cones and pods and also consumes nectar from flowering plants.

Bird feeders

At bird feeders, green rosellas are known to consume a variety of seeds including sunflower seeds, millet, and cracked corn. They may also enjoy fruits such as apples and pears offered at feeders. Additionally, they might feed on specially formulated parrot pellets and are sometimes attracted to the nectar of nearby flowering plants if present.

How to tell the Northern Rosella from the Green Rosella

Visual differences

The Northern Rosella measures approximately 11-12.5 inches with a striking black head, white cheeks, blue patch, red and blue belly, and scalloped black-and-yellow wings. In contrast, the Green Rosella is larger at up to 14.5 inches, predominantly green with blue on the head and wings, and a yellow stomach. Both species have subtle gender dimorphism with males slightly larger. Juvenile Northern Rosellas have more green plumage, while young Green Rosellas have muted colors. The Northern Rosella has a medium-sized beak, whereas Green Rosellas possess stronger, broader beaks.

Key differences and behavior

The Northern Rosella and Green Rosella exhibit distinct behaviors and preferences. Northern Rosellas are less sociable, sticking to family units even after young birds fledge, while Green Rosellas are gregarious, often seen in flocks of over 20. Both species engage in mutual preening during courtship, but Green Rosellas use vocalizations as well. Northern Rosellas inhabit tropical woodlands in Australia's north, whereas Green Rosellas are found in Tasmania's rainforests, woodlands, and gardens. Their diets are similar, both consuming seeds, fruits, and insects, though Northern Rosellas notably partake in eucalyptus nectar, aiding pollination. Both species nest in tree hollows, with similar parental care, but Northern Rosellas may also nest in suburban areas.
