The report by Matthew Wood found the breeding pairs of brolgas have dropped from seven down to two in the first four years. [23][24] Both sexes incubate the eggs, with the female sitting on the nest at night. Each family in the flock is led by a male. Brolgas are widespread and often abundant in north and north-east Australia, especially north-east Queensland, and are common as far south as Victoria.They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia.The population in northern Australia is estimated at between 20,000 and 100,000 birds and in southern Australia, 1,000 birds. Calling it the Australian crane, he mentioned that its early colonial name had been native companion. The brolga is found in the northern and eastern parts of Australia, in wetland areas. Brolgas are widespread and often abundant in north and north-east Australia, especially north-east Queensland, and are common as far south as Victoria. [From Kamilaroi (Pama-Nyungan language of southeast Australia) burralga or a kindred source in other Pama-Nyungan languages of southeast Australia.] Although the population may be declining slowly, this is not at a rate that would warrant the brolga being included in a more vulnerable category. They are also known as Australian Cranes or by their former name: Native Companion. We're a national non-profit conserving biodiversity in Australia. The adults continue to protect the young for up to 11 months, or for nearly 2 years if they do not breed again in the interim. Photo Alec Brennan. [7], Brolgas are well known for their ritualised, intricate mating dances. [22] Flocks were relatively rarer, but birds in flocks in the Flinders river floodplain comprised 80% of all brolgas counted. [20] The bird is the official bird emblem for the state and also appears on its coat of arms. The male stands alongside in a similar posture, but with his wings flared and primaries drooping, which is the only time when sex can be differentiated reliably. Recognise the birds in the nature. The chicks fledge within 4–5 weeks, are fully feathered within 3 months, and are able to fly about 2 weeks later. Brolgas are non-migratory, but make seasonal movements depending on rain levels. The Birds in Backyards Program is currently running three surveys which require volunteer assistance. A large Australian crane (Grus rubicunda) with a bare greenish head and a red stripe around the neck. Within the flock, families sometimes remain separate and coordinate their activities with one another rather than with the flock as a whole. [12] The adult has a grey-green, skin-covered crown, and the face, cheeks, and throat pouch are also featherless and are coral red. Breeding
Brolgas mate for life. [17] Until 1961, brolgas were thought to be the only species of crane in Australia, until the sarus crane was also located in Queensland. Donations over $2 are tax-deductible and we can't thank you enough for your support. A former pastoral property, it's located in the Warrego-Paroo River catchment in north-western NSW, one of the least disturbed parts of the Murray-Darling Basin. They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia. Brolga numbers were highest in floodplains where grassland habitats dominated, and the largest flocks were also found in grassland habitats. I hope that you found these facts interesting and learned something new. [17], Further south, in Victoria and New South Wales, rainfall is spread more evenly throughout the year and the driest season lasts from December to May. The clutch size is usually two, but occasionally one or three eggs[24] are laid about two days apart. Brolgas can be found in a surprising variety of habitats. Habitat and Range The Brolga is found across tropical northern Australia, southwards through north-east and east central areas, as well as central New South Wales to western Victoria. The sexes are indistinguishable in appearance, though females are usually a little smaller. When the wet season is over they may have to fly large distances to find food. Unlike most other river systems in the Basin, there's minimal water extraction in the Warrego-Paroo system, allowing the area to flood and dry naturally. In saltwater marshes, they may drink saline water and they have glands near their eyes through which they can excrete excess salt. Brolgas probably mate for life, and pair bonds are strengthened during elaborate courtship displays, which involve much dancing, leaping, wing-flapping and loud trumpeting. Brolgas are normally found in large noisy flocks (sometimes 1,000 or more) Each family group in the flock is lead by a male. Cranes are a family of tall wading birds that look a bit like herons, and are found all over the world. But the southern population – estimated at 1,000 birds – is dwindling, and the species is listed as vulnerable in NSW, South Australia and Victoria. They mate for life and are well known for their majestic dancing during mating season. It also inhabits southern New Guinea, parts of northern Western Australia and New Zealand. During the non breeding period from late December to early May habitat comprises deep freshwater marshes, vegetated areas in permanent open water and feeding areas in pasture, seed and stubble crops. Recognise the birds in the nature. They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia. We work with universities, and experts like ornithologist (bird specialist) Professor Richard Kingsford on Naree, who has been monitoring waterbirds across inland Australia since 1986. [27], The suspected chief threats faced by the brolga, particularly in the southern part of its range, are habitat destruction particularly spread of blue gum (Eucalyptus globulus) into breeding habitats, the drainage of wetlands, collision with powerlines, burning and grazing regimes, spread of invasive species, and harvesting of eggs. A total of 449 birds were observed on the one day. For brolgas the wind farm was supposed to have a net zero impact. The Brolga is a species of crane found in Australia and New Guinea. It has also been given the name Australian crane, a term coined in 1865 by well-known ornithologist John Gould in his Birds of Australia. Find out more using the fact sheets and also why the Birds in Backyards program is interested in gathering data for these species. “This part of the world is really important for these birds,” explains Richard. They are also known as Australian Cranes or by their former name: Native Companion. “Famous for its stately dancing displays and known as the ‘native companion’ the Brolga is found mostly in eastern and northern Australia. Brolgas may search for cooler air by flying to high altitudes. At this time, southern populations congregate in inland flocking areas, which include upland marshes, the edges of reservoirs and lakes, pastures, and agricultural land. Adult males average in body mass 6.8 kg (15 lb) with females averaging 5.66 kg (12.5 lb). However, their conservation status varies from state to state within Australia. The population in northern Australia is estimated at between 20,000 and 100,000 birds and in southern Australia, 1,000 birds. The Brolga is omnivorous and utilise… [25], Conservation measures being undertaken include international cooperation, legal protection, research, monitoring, habitat management, education, and the maintenance of captive flocks for propagation and reintroduction. In breeding areas, breeding pairs defend territories against other brolgas, and when breeding efforts are successful, remain in territories with one or two chicks. Adapted by Kathleen Simonetta. Jimmy Morrill & the Brolgas sculpture commemorates the centenary of the Pioneer Sugar Mill. [7], The brolga was formerly placed in the genus Grus, but a molecular phylogenetic study published in 2010 found that the genus, as then defined, was polyphyletic. WHY BROLGAS BIRDS DANCE A tale from Australia A long time ago in the Australian outback there lived a girl named Brolga who loved to dance. Yes. Each family used multiple wetlands within their territories, either switching between them, or using wetlands sequentially. Vulnerable in NSW, SA and Vic. Here, it may be barely discernible as it wheels in great circles, sometimes emitting its hoarse cry.[3]. Though brolgas are widespread across Australia, and most commonly found in the north, one of their most important areas in southern Australia is around Naree. [17] In south-west Victoria, breeding sites during and immediately after spring are freshwater wetlands, while freshwater, brackish and saline wetland sites used for flocking during the autumn. Perhaps you’ve seen a pair of Brolgas, wings beating slowly, crying hoarsely as they travel from wetland to wetland? He also recorded that it was easy to tame, and that James Macarthur had kept a pair at his home in Camden. [11], The brolga is a tall bird with a large beak, long, slender neck, and stilt-like legs. [23] Nests were initiated between November and February in the Gilbert and Flinders River basins, and tracked rainfall episodes in each river basin. Their diet in dry season flocks at Atherton Highlands likely are very different owing to the largely agricultural landscape. This was further confirmed by molecular studies of their DNA. Sometimes, the birds make hardly any nest, take over a disused swan nest, or simply lay on bare ground. [25] Families roosted in wetlands at night, and moved an average distance of 442 m to and from these night roosts. The largest flock recorded was of 130 birds north of Penshurst. Brolgas are monogamous and usually bond for life, though new pairings may follow a death of one individual. They are commonly found throughout northern and eastern regions of Australia in large open wetlands, grassy plains and coastal mud flats. The energetic dance performed by the Brolga is a spectacular sight. They are also found in southern New Guinea and as rare vagrants in New Zealandand the northern part of Western Australia. Its plumage is mainly grey, with black wing tips, and it has an orange-red band of colour on its head. The feathers on the back and the wing coverts have pale margins. They line up … The brolga (Antigone rubicunda), formerly known as the native companion, is a bird in the crane family. [22], Brolgas' social unit is very similar to that observed in sarus cranes. Acrylic Painting on Linen Marlene Norman Brolgas are large beautiful birds found abundant in our country. Southern and Northern brolgas, although regarded as discrete populations, are actually one crane species (Grus rubicunda) and they share spectacular and endearing characteristics. Brolgas in flight over Naree Station, NSW. When the wet season is over they may have to fly large distances to find food. Brolgas are widespread and often abundant in north and north-east Australia, especially north-east Queensland, and are common as far south as Victoria. The brolga is more silvery-grey in colour than the sarus, the legs are blackish rather than pink, and the trumpeting and grating calls it makes are at a lower pitch. The Brolga is quite unmistakable in southern Australia. The ear coverts appear as a grey patch of small feathers surrounded by red naked skin and the body plumage is silvery-grey. Brolga Identification. The beak is greyish-green in adult birds, long and slender, and the irises are yellowish-orange. Brolga footprint in the dried floor of a dune swale ephemeral wetland after winter rain, Craven's Peak, Qld. An isolated territory is established, and is vigorously defended by both partners. The Brolga is a species of crane found in Australia and New Guinea. They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia. The male emits one longer call for every two emitted by the female. [22] They also eat the shoots and leaves of wetland and upland plants, cereal grains, seeds, insects, mollusks, crustaceans, frogs, and lizards. But this powerful place contained the essence of the Brolga and we would love to be there at the end of the wet, when the Brolgas make it all their own. Brolgas do not migrate, and have been known to use the same nesting site for up to 20 years. [19], Queensland has the greatest numbers of brolgas, and sometimes flocks of over 1,000 individuals are seen. The Brolga inhabits large open wetlands, grassy plains, coastal mudflats and irrigated croplands and, less... Distribution. Brolgas are one of Australia’s largest flying birds – they stand a metre tall and have a wing span up to 2.4 metres. Maryborough naturalist Hugh Peddie said Brolgas could be seen locally. The Brolga is a large grey crane, with a featherless red head and grey crown. They live in open wet lands, grassy plains, mud flats, crop lands and creeks.
4. With such an impressive mating ritual it’s little wonder that Brolgas pair for life.

Brolgas are omnivorous, eating roots, seeds, plants, frogs, insects, lizards and other small animals. Brolgas got their name from the aboriginal (indigenous people of Australia) language of … "Brolgas are slightly smaller so it's probable that sarus cranes that are initiating it." [22] Nonbreeding birds that constitute young birds of past years, as well as adults that likely do not yet have breeding territories, are also found in breeding areas, likely throughout the year. [4] Breeding pairs maintain discrete territories within which they raise chicks. Most of our operating costs are funded by generous individuals. [22] Wind farms are an emerging threat, and research on movement and habitat use by breeding pairs and chicks show the importance of locating turbines away from wetlands important for night roosting. When threatened, they hide and stay quiet, while the parents perform a broken-wing display to distract the predator. Brolgas got their name from the aboriginal (indigenous people of Australia) language of … [15][16] Per a manual of avian body mass, the brolga is the heaviest flying bird regularly found in mainland Australia, averaging slightly higher in body mass than other large resident species such as black swan, Australian pelican and the Australian population of the sarus crane (as well as much heavier on average than the biggest flying land birds such as the very sexually-dimorphic Australian bustard and wedge-tailed eagle), although heavier birds such as wandering albatross may be seen as marine vagrants off the mainland. The Australian population of Brolgas is considered ‘secure’, with somewhere between 20,000 to 100,000 birds in northern Australia.
