Currawongs are striking medium-sized birds native to Australasia, renowned for their distinctive calls and versatile behavior. Belonging to the family Artamidae, these birds have captivated the attention of birdwatchers and naturalists alike due to their unique blend of crow-like and magpie-like features. Often mistaken for crows or ravens, currawongs possess several distinctive traits, including their remarkable vocalizations and varied diets. Their common name is derived from the evocative, ringing call of the Pied Currawong (Strepera graculina), a well-known species found primarily in eastern Australia. This vocalization has become synonymous with Australian woodlands and suburban areas where these birds frequently make their presence known.
Scientific Classification
Currawongs belong to the genus Strepera, within the family Artamidae, which also includes the woodswallows and butcherbirds. The genus name Strepera originates from Latin, meaning “noisy” or “loud,” aptly describing the birds’ characteristic calls. Historically, currawongs were once classified with crows and shrikes due to their appearance and behavior, earning them the colloquial name “crow-shrikes.” However, taxonomic revisions based on genetic and behavioral studies have placed them closer to butcherbirds and woodswallows.
There are three primary species of currawong, each with several recognized subspecies or races reflecting their geographic variation:
1. Pied Currawong (Strepera graculina) – The most widespread species, found in eastern Australia and Tasmania. It includes subspecies such as S. g. graculina (eastern Australia), S. g. ashbyi (western Victoria), S. g. crissalis (Lord Howe Island), and others.
2. Grey Currawong (Strepera versicolor) – Found primarily in southern Australia, including western Victoria, South Australia, and Tasmania. This species exhibits several subspecies such as S. v. versicolor (mainland), S. v. halmaturina (Kangaroo Island), and S. v. arguta (the “Clinking Currawong”, sometimes called Black Magpie).
3. Black Currawong (Strepera fuliginosa) – Endemic to Tasmania and nearby islands like King Island (S. f. colei) and Flinders Island (S. f. parvior).
All currawongs share a close evolutionary relationship with butcherbirds (Cracticus) and Australian magpies (Gymnorhina tibicen), forming a distinct group of songbirds renowned for their intelligence and adaptability.
Geographic Range & Distribution
Currawongs are endemic to the Australasian region, with their range primarily restricted to Australia and the island of Tasmania, including several offshore islands. The Pied Currawong (Strepera graculina) has the widest distribution, inhabiting eastern Australia from northern Queensland down through New South Wales, Victoria, and into Tasmania. It is commonly found in forested areas, woodlands, and even urban parks and gardens, displaying remarkable adaptability to human-altered landscapes.
The Grey Currawong (Strepera versicolor) occupies a broader but more fragmented range across southern Australia, including parts of Western Australia, South Australia, Victoria, and Tasmania. This species is typically associated with dense eucalypt forests and coastal scrublands, often favoring more temperate regions.
The Black Currawong (Strepera fuliginosa) is restricted to Tasmania and its offshore islands, including King Island and Flinders Island. It prefers highland and subalpine forests, often favoring wetter habitats such as rainforests and wet sclerophyll forests.
Currawongs are generally sedentary, tending to remain within their established territories year-round. However, some local movements may occur, especially in response to food availability or seasonal changes. Their strong territoriality and vocal presence make them a familiar and unmistakable component of the Australian avifauna.
Physical Description
Currawongs are medium-sized passerines, measuring between 44 and 54 centimeters in length, with wingspans ranging from approximately 70 to 85 centimeters. They weigh between 250 to 400 grams depending on species and sex, with males typically being slightly larger than females. Their robust bodies, strong legs, and powerful bills enable them to be highly effective foragers and hunters.
The Pied Currawong is perhaps the most visually striking species, characterized by its predominantly black plumage contrasted with prominent white patches on the wings and tail. Its tail is long and slightly rounded, often fanned during displays. The eyes of the Pied Currawong are a distinctive pale yellow or white, which sets them apart from the red eyes commonly found in magpies and the dark eyes of crows and ravens.
The Grey Currawong displays a more subdued coloration, with slate-grey to dark brown plumage and less conspicuous white wing markings. Subspecies variations include the “Clinking Currawong” (S. v. arguta), which has a more slender build and a distinctive clinking call. The Black Currawong is the darkest of the three, with entirely black plumage and subtle glossing, and pale yellow eyes similar to its relatives.
Currawongs have strong, slightly hooked bills that assist in tearing flesh, manipulating fruit, and extracting insects from crevices. Their legs and feet are sturdy, allowing them to perch confidently on branches or forage on the ground. Overall, their appearance is sleek and powerful, reflecting their versatile lifestyle as both predators and scavengers.
Behavior & Diet
Currawongs are highly intelligent and adaptable birds, exhibiting a broad range of behaviors including complex vocalizations, social interactions, and varied feeding strategies. They are generally territorial and vocal throughout the year, using a series of melodious, ringing calls that differ between species and regions. The Pied Currawong’s resonant “currawong” call is especially well-known and often described as a haunting, flute-like series of whistles and caws. According to RSPB, this species is well documented.
These birds are omnivorous opportunists, with diets that include insects, other invertebrates, small vertebrates, fruits, and occasionally the eggs and nestlings of other birds. Their strong bills allow them to forage effectively in diverse environments. Currawongs often search for insects and larvae beneath tree bark, flicking aside leaves and debris on the forest floor or probing into crevices. They are known to prey on small mammals, reptiles, and amphibians, showcasing their role as important predators in their ecosystems. According to eBird, this species is well documented.
Fruit is another significant component of their diet, with currawongs feeding on native berries, figs, and other fleshy fruits. This frugivory makes them crucial seed dispersers for a variety of Australian plants. They have also been observed scavenging on carrion and human scraps in urban areas, demonstrating their adaptability.
Currawongs often forage alone or in small groups and can be seen hopping and flitting through the canopy or hopping on the ground. Despite their crow-like appearance, they are less likely to scavenge in large crowds and are more solitary or paired during foraging. Their ability to exploit multiple food sources allows them to thrive in both natural and suburban environments.
Breeding & Reproduction
Currawongs are monogamous and territorial breeders, typically nesting during the Australian spring and summer months. They construct bulky, cup-shaped nests made of twigs, grass, and other plant material, usually placed high in the forks of eucalyptus or other tall trees. The nest is often lined with softer materials such as leaves and grass to provide a comfortable environment for the eggs and chicks.
The female lays between two to four pale green or bluish eggs, often speckled with brown or purple markings. Incubation lasts approximately 18 to 21 days and is primarily performed by the female, although males may assist in feeding the female during this period. After hatching, both parents share the responsibility of feeding the chicks, which are altricial (born naked and helpless) and require significant parental care.
Currawong chicks fledge about 25 to 30 days after hatching but often remain dependent on their parents for several weeks as they learn to forage and fly proficiently. Juveniles are initially duller in coloration and gradually develop the adult plumage over the first year. Breeding success can vary due to predation, food availability, and environmental conditions.
Conservation Status
Overall, currawongs are not considered globally threatened. The International Union for Conservation of Nature (IUCN) lists the Pied Currawong (Strepera graculina) and Grey Currawong (Strepera versicolor) as species of Least Concern due to their stable and widespread populations. The Black Currawong (Strepera fuliginosa) is also classified as Least Concern but has a more limited distribution, making habitat preservation on Tasmania and surrounding islands particularly important.
Despite their general stability, currawongs face threats from habitat loss, fragmentation, and changes in land use, especially in urban and agricultural areas. In some regions, they are considered a nuisance species due to their predation on smaller native birds and their adaptability to suburban environments. However, their role as seed dispersers and insect predators highlights their ecological importance.
Conservation efforts for currawongs focus on preserving native forests and woodlands, maintaining habitat connectivity, and monitoring populations to ensure long-term viability. Because they are adaptable and intelligent, currawongs provide an excellent example of how wildlife can coexist with human development when natural habitats are protected and urban environments are managed thoughtfully.
Interesting Facts
Currawongs are often noted for their remarkable vocal abilities. Their calls can vary widely across regions and species, sometimes mimicking other birds or environmental sounds. This vocal versatility is thought to play a role in territorial defense and mate communication. The Pied Currawong’s call is so distinctive that it has been widely recorded and used in Australian media and folklore.
Another fascinating aspect of currawong behavior is their inquisitiveness and problem-solving skills. They have been observed using tools, such as sticks, to extract insects from tree bark, and they show an ability to remember food sources and avoid traps. Their intelligence places them among some of the smartest native Australian birds.
Currawongs also have a reputation for their predatory habits. While primarily insectivorous and frugivorous, they sometimes raid nests of smaller birds, which has led to some conflict with conservationists trying to protect vulnerable species. Nonetheless, this behavior is a natural part of their ecological niche.
Finally, the Black Currawong of Tasmania is a unique species that thrives in cooler, wetter habitats, often at higher elevations than its relatives. Its striking all-black appearance and haunting calls make it a favorite among birdwatchers visiting Tasmania’s forests and mountains.
In summary, currawongs are a fascinating group of birds that combine striking appearance, complex behavior, and ecological versatility. Their presence across diverse Australian landscapes, from dense forests to urban gardens, highlights their adaptability and importance within the region’s natural heritage.
