Bowerbirds are renowned for their unique courtship behaviour, where males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. They are found in the tropical northern part of Australia and New Guinea, with some species extending into the central Australian desert and the cold mountainous regions of southeast Australia. Satin Bowerbirds, for example, are found along the eastern and southeastern coasts of Australia, while Western Bowerbirds are found in the arid central regions of the country.

Satin Bowerbirds are found along the eastern and southeastern coasts of Australia
Satin Bowerbirds are medium-sized birds with vibrant blue-violet eyes. The adult male has striking glossy blue-black plumage, a pale bluish-white bill, and a violet-blue iris. Younger males and females, known as "green" birds, have similar olive-green colouring, with off-white and dark scalloping and brown wings and tails. The male Satin Bowerbird is well-known for its practice of building and decorating an elaborate bower to attract females. This bower consists of two parallel walls of sticks, built on the ground, and decorated with bright blue objects like parrot feathers, flowers, and artificial items.
Satin Bowerbirds prefer wetter forests and woodlands with nearby open areas. They are found in the Atherton Tableland, where they inhabit rainforests. These birds have an interesting variety of sounds, including whistles, buzzing, hissing, and mimicry. They are a favourite among bird watchers due to their intriguing behaviour and colourful appearance.
The diet of Satin Bowerbirds consists primarily of fruits throughout the year. During the summer breeding season, they supplement their diet with insects, while leaves are consumed during the winter months. Satin Bowerbirds are solitary, but the "green" birds are often seen in groups or large flocks. During winter, outside of the breeding season, these birds move to more open country and may enter orchards, sometimes joining the "green" bird flocks.

Western Bowerbirds are found in central Australia and the Pilbara region of Western Australia
The Western Bowerbird (Chlamydera guttata) is a species of bird in the Bowerbird family. It is a common endemic of Australia, with a disjunct distribution. Western Bowerbirds are found in central Australia and the Pilbara region of Western Australia, as well as the North West Cape in Western Australia. They inhabit arid open scrubland and desert regions, often near permanent waterholes, gorges, and rocky hills. They are also known to inhabit semi-arid regions where native figs are found.
Western Bowerbirds have a distinctive appearance, with a brown spotted body, a pink patch on the back of the neck, and a paler chest and belly. They measure around 25-30 cm in length and weigh between 120 and 150 grams. They are known for their elaborate bowers, which are constructed by males to attract females. These bowers are built on the ground and consist of paired avenues of sticks, placed on top of a platform of sticks. The bowers are decorated with green and white objects, including berries, fruits, shells, pebbles, and bones. Man-made objects such as glass, gun casings, and metal objects may also be used for decoration.
The Western Bowerbird is polygamous, with males mating with several females over a breeding season. The female undertakes all nesting, incubation, and chick-rearing responsibilities. Western Bowerbirds forage in shrubs or trees for fruit, insects, and seeds, and they particularly enjoy rock figs. They can be found in open riverine woodland and shrub thickets in arid zones, near water.
Western Bowerbirds are known for their loud and harsh calls, which include churring, hissing, and grating sounds, as well as mimicry of bird calls and other sounds. They are similar to the Spotted Bowerbird (Chlamydera maculata) and have sometimes been treated as a subspecies of it. However, the Western Bowerbird is smaller and darker, particularly on the head and neck, with a slightly shorter tail and bill.

Spotted Bowerbirds are found across inland Queensland and New South Wales
The Spotted Bowerbird (Chlamydera maculata) is a mid-sized passerine found across inland Queensland and New South Wales in Australia. It is a sedentary species, known for its remarkable behaviours, including bower-building and decoration, courtship displays, and vocal mimicry. Spotted Bowerbirds are endemic to eastern mainland Australia, and are most commonly found in dry, open woodlands with a dense understory of small trees and shrubs. They have a strong preference for habitats dominated by eucalypt and/or brigalow, and are often associated with riverine woodlands, orchards, parks, and rural homesteads and gardens.
Spotted Bowerbirds are well-camouflaged and can be difficult to spot among the vegetation. They are generally active and, although often shy, they can be quite tame near human habitation. Their presence may be indicated by their distinctive avenue-type bower, typically built under a shrub and decorated with whitish, green, red, or shiny objects, including bones, snail shells, and berries, as well as metallic and glass items.
The species is known to be polygynous, and males build and maintain bowers to attract potential mates. These structures serve as a focal point for social activities and are thought to indicate male quality. The female Spotted Bowerbird builds the nest and cares for the young, while the male plays no part in parental care.
Spotted Bowerbirds are locally common, but the overall population is thought to be in decline, with local extinctions occurring across much of its range, particularly in the southwest. The species is now extinct in South Australia, where it once had a small range. Conservation efforts are focused on protecting their habitats to ensure the long-term survival of this unique species.

Bowerbirds are found in tropical northern Australia and New Guinea
The distribution of bowerbirds is centred around the tropical regions of northern Australia and New Guinea, with some species extending into the central Australian desert and the southeastern mountainous regions. One notable species, the Western Bowerbird, is endemic to central and inland arid regions of Australia, often found near water in open riverine woodlands and shrub thickets.
The Satin Bowerbird, found along the eastern and southeastern coasts of Australia, is particularly well-known for its practice of decorating its bower with blue objects like clothes pegs, drinking straws, bottle tops, and parrot feathers. This species prefers wetter forests, woodlands, and nearby open areas, including rainforests in the Atherton Tableland region.
Another species, the Spotted Bowerbird, is distributed across inland Queensland and New South Wales in Australia. The Sanford's Bowerbird, on the other hand, inhabits the eastern highlands of Papua New Guinea and exhibits polygamous behaviour.
Bowerbirds are generally medium to large-sized passerines, with complex behavioural patterns. They forage for fruit, insects, and seeds in shrubs and trees, and their diet may also include flowers, nectar, and leaves depending on the species. The female bowerbird is typically responsible for building the nest and raising the young alone, while males focus on constructing their bowers and attracting mates.

They are also found in the cold mountainous regions of southeast Australia
While the distribution of bowerbirds is centred around the tropical northern part of Australia and New Guinea, some species of these birds can be found in the cold mountainous regions of southeast Australia.
The Australian Alps, for instance, is a mountain range situated in southeastern Australia, specifically in the territories of Victoria, New South Wales, and the Australian Capital Territory. The Australian Alps is the only area on mainland Australia that receives deep snowfall each year, and it is home to the country's highest peaks, including Mount Kosciuszko, which stands at 2,228 metres. The Snowy Mountains, which contain the five highest peaks on mainland Australia, are a bio-geographical subregion of the Australian Alps. Known as "The Snowies", this range is usually covered in snow for the entirety of June, July, August, and September, and is the centre of Australia's ski industry.
The Blue Mountains are another mountain range located in southeastern Australia, about 50 kilometres west of Sydney in New South Wales. The unique landscape, vegetation, and wildlife of the Blue Mountains have earned them a spot on UNESCO's list of official World Heritage Areas.
In addition to these mountain ranges, southeastern Australia also includes semi-arid regions and mountainous landscapes. The Great Australian Desert, which covers about 40% of the country, is diverse, with semi-desert grassy or mountainous landscapes, xeric shrubs, salt pans, stony deserts, red sand dunes, sandstone mesas, rocky plains, open tree savannahs, and bushland. The regions bordering the Gibson Desert in the far southeast, for instance, record light frost every year.
