Crimson Rosella vs Green Rosella

Crimson Rosella

Platycercus elegans

How to recognise a crimson rosella?

General appearance

The Crimson Rosella is an eye-catching bird found in eastern and southeastern Australia. It's most known for its vibrant red color, complemented with patches of blue on its cheeks, wings and tail. The beauty of its plumage is further accentuated by black feathers on its back and an aerodynamic shape increasing its grace in flight.

Male vs female

Males and females share similar coloration, making gender determination challenging. However, mature males have slightly broader heads and beaks. Their color is also a bit more vibrant compared to the females. The females have comparatively thinner and pale beaks, which is one of the most prominent distinguishing features.

Juvenile

Juvenile Crimson Rosellas vary in color, making them fascinatingly different from adults. They initially have an olive-green plumage which, with time, morphs into an adult's characteristic crimson and blue color. Their color transformation is a gradual process that takes about 15 months. Therefore, recognizing a young Crimson Rosella can be difficult without knowledge of their early coloration.

What do crimson rosellas like to eat?

Natural diet

Crimson rosellas primarily feed on a variety of seeds, fruits, nuts, berries, nectar, and blossoms found in their natural habitat. They forage in the trees and on the ground, consuming seeds from grasses, eucalypts, and acacias along with fruits and nuts from native shrubs and trees. These parrots also eat insects and their larvae, which provide essential proteins.

Bird feeders

At bird feeders, crimson rosellas often enjoy sunflower seeds, millet, and cracked corn. They are also attracted to fruit offerings like apples, pears, and grapes. Providing a diverse mix of seeds along with fresh fruit can attract these vivid birds, catering to their varied dietary preferences. However, it's important to maintain a balanced diet and avoid overfeeding them processed or unhealthy foods.

What does a crimson rosella sound like?

The Crimson Rosella vocalizes with a series of sharp, metallic, piping notes, usually in groups of 3 or 6. Its most common call is a 4-note "cossack-cossack-cossack-cossack", heard mainly at dawn and dusk. More prolonged songs, often during flight, are composed of a series of different notes and sound similar to ringing telephone. Additionally, they can mimic human speech when kept as pets. Even their alarm call is melodious, made up of a rapid and high-pitched succession of notes.

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 Crimson Rosella from the Green Rosella

Visual differences

The Crimson Rosella is known for its vibrant red plumage with blue patches on the cheeks, wings, and tail, and black feathers on the back. In contrast, the Green Rosella is primarily green with blue on the head and wings and a yellowish stomach. Crimson Rosellas range from 11.8 to 14.6 inches in length, similar to Green Rosellas at 11.4 to 14.2 inches. However, Green Rosellas are the largest rosella species with robust beaks. Identifying juveniles involves recognizing their muted colors transforming to adult hues over time.

Key differences and behavior

Crimson Rosellas (30-37 cm, 72-170 g) and Green Rosellas (29-36 cm, 90-165 g) display distinct behaviors and habitats. Crimson Rosellas, social in nature, form feeding parties and adapt to diverse habitats, including forests and urban parks in southeastern Australia. Their diet combines seeds, fruits, and insects both in the wild and at feeders. Green Rosellas, Tasmania-native, favor rainforests and shrublands, often foraging in large groups of over 20 birds in tree canopies. They also utilize suburban gardens. Both species engage in courtship through vocalizations and mutual preening/feeding, nest in tree hollows, and involve both parents in offspring care. While feeding, both enjoy seeds and fruits, though Green Rosellas uniquely extract seeds using robust beaks and may indulge in nectar. Despite similar social behaviors, they adapt to different environments and slight dietary preferences.
