What You'll Learn
Australian brush turkeys are 60-75cm long with an 85cm wingspan
The Australian brush turkey is a large bird, measuring 60-75cm in length and boasting an impressive 85cm wingspan. It is the largest of Australia's three megapodes, a distinct family of fowl-like birds. This bird is easily recognisable, with its black feathers and red head. The male brush turkey has a large, bright yellow flap of skin that hangs from its neck, known as a wattle, while the female has a smaller and paler wattle.
The Australian brush turkey is a common species of mound-building bird, found in eastern Australia, from Far North Queensland to Eurobodalla on the South Coast of New South Wales. They inhabit rainforests, wet sclerophyll forests, and drier scrubs and open areas.
The male brush turkey works tirelessly to construct a mound for nesting, made from leaves, compostable material, and earth. These mounds can be quite large, reaching up to 1 to 1.5 metres high and 4 metres across. The female brush turkey will then lay her eggs in the mound, and the heat generated by the decomposing vegetation incubates them. The male plays an important role in maintaining the optimal incubation temperature of 33-35 degrees Celsius by adjusting the mound as needed.
Despite their large size, Australian brush turkeys are clumsy fliers and can only fly short distances when threatened by predators or to roost in trees during the night or hot parts of the day. They are known to frequent urban areas, where they exhibit bold behaviour in search of food and nesting materials.

Males weigh 2.45kg and females 2.21kg
The Australian brush turkey is a large, ground-dwelling bird native to Australia. While it is similar in shape to the domestic turkey, it belongs to the megapode family. This species differs from other birds as it does not incubate its eggs using body heat. Instead, the male brush turkey builds a large mound, up to 4 metres high and containing almost 500 million litres of rotting vegetation, which incubates the eggs through the heat generated by the decomposition process.
Males of this species weigh around 2.45 kg, while females are slightly smaller, weighing approximately 2.21 kg. This weight difference is not surprising, as male birds often have larger bodies and more robust physical features than their female counterparts.
The weight difference between the sexes can be attributed to a variety of factors, including behavioural and ecological adaptations. Male brush turkeys, for instance, are responsible for building the enormous mounds that incubate their eggs. This labour-intensive process requires males to be robust and strong, hence their larger size.
Female brush turkeys, on the other hand, contribute to reproduction by laying eggs, which are then incubated in the mounds built by males. Their slightly smaller size may offer benefits in terms of manoeuvrability and energy efficiency, allowing them to efficiently forage for food and care for their young once they hatch.
These weight disparities reflect the unique reproductive strategies employed by Australian brush turkeys, highlighting the fascinating adaptations that nature has crafted to ensure the survival and perpetuity of this distinctive species.

They are large, ground-dwelling birds
The Australian brush turkey is a large, ground-dwelling bird, with a total length of about 60–75 cm (23.5–29.5 in) and a wingspan of about 85 cm (33 in). It is the largest of Australia's three megapodes, a distinct family of fowl-like birds that includes quails, turkeys, peafowl, and junglefowl.
The brush turkey is a common and widespread species found in eastern Australia, from Far North Queensland to Eurobodalla on the South Coast of New South Wales. It inhabits rainforests, wet sclerophyll forests, and drier scrubs and open areas. In the northern part of its range, it is typically found at higher altitudes, while in the south, it is common in both mountain and lowland regions.
As its name suggests, the brush turkey is a ground-dwelling bird that spends much of its time raking the leaf litter and digging in the dirt with its large feet to find food and gather materials for its distinctive mound nests. The male brush turkey works tirelessly to build these large mounds, which can be up to 4 m (13 ft) wide and 1-1.5 m (3.3-4.9 ft) high, by collecting leaves, earth, and other compostable materials.
The Australian brush turkey's large size and ground-dwelling habits make it a familiar sight in many urban and suburban areas, where it is known to raid compost bins and strip gardens of their mulch for nesting material. Despite its size, the brush turkey is a clumsy flyer, taking to the air only when threatened by predators or to roost in trees at night and during the hottest parts of the day.

They have black-brown plumage and a red head
The Australian brush turkey is a large bird, with a total length of about 60–75 cm (23.5–29.5 in) and a wingspan of about 85 cm (33 in). Its plumage is described as black-brown, with a prominent, fan-like tail flattened sideways. The subspecies A. l. purpureicollis from the northern Cape York Peninsula is smaller than the more widespread nominate subspecies.
The brush turkey's head is perhaps its most distinctive feature. It is featherless and red, with a yellow throat wattle (in the nominate subspecies) or purple wattle (in A. l. purpureicollis). The wattle is a loose flap of skin around the base of the neck, and it is larger in males, especially during the breeding and nesting season. The males' heads and wattles also become much brighter during this time.
The brush turkey's neck is deep red and featherless, with grey edges on the breast feathers. The chicks, however, have all-brown feathers for camouflage. As they grow, their feathers gradually change to the blue-black plumage of the adults, and their heads and necks turn a featherless rich pink.
The Australian brush turkey is easily distinguished from other Australian birds due to its unique combination of black-brown plumage and a red head. This distinctive appearance has made it an unmistakable bird in its native habitat, which ranges from Cape York Peninsula in Far North Queensland to south Wollongong in New South Wales.

They are one of three Australian mound-building birds
The Australian brush turkey, also known as the gweela, is one of three Australian mound-building birds. The other two species are the malleefowl and the orange-footed scrubfowl. The brush turkey is the largest of the three, with a total length of about 60–75 cm (23.5–29.5 in) and a wingspan of about 85 cm (33 in). In comparison, the orange-footed scrubfowl is smaller, measuring about 45 cm, while the malleefowl is brown, barred with black, white, and rufous.
Australian brush turkeys are found in eastern Australia, from Far North Queensland to Eurobodalla on the South Coast of New South Wales. They inhabit rainforests, wet sclerophyll forests, and drier scrubs and open areas. They are known for their distinctive appearance, with black feathers, a red head, and a yellow or purple wattle. The males' wattles become larger during the breeding season, and their heads and wattles become brighter.
These birds build large nests on the ground made of leaves, compostable material, and earth. The nests can be up to 1 to 1.5 meters high and 4 meters across. The mound-building is done by a dominant male, who collects material and repels rival males. The female brush turkeys then visit these mounds for mating and egg-laying. The male regulates the temperature of the mound by adding or removing material to maintain a temperature range of 33–38 °C, ideal for incubating the eggs.
The Australian brush turkey is a protected species in Queensland, with offences against the bird incurring hefty fines or imprisonment under the Nature Conservation Act 1992. Despite this, they can sometimes be a nuisance in urban areas, damaging gardens and landscaping while searching for food or building their mounds.
