Since the 1970s, the Australian White Ibis (Threskiornis molucca) has increased in abundance in coastal urban environments, where its high numbers can come into conflict with human interests.Little is known about them, and baseline information for appropriate management is lacking. An Australian White Ibis chick. They’re a fairly big bird (about 70 cm long) and they are almost entirely white, with a black head and neck and a long curved beak. The avifauna of Australia is made up of 531 species of breeding land and freshwater birds, and is the smallest numerically of the continents. This species breeds in large colonies alongside herons, egrets and spoonbills. [9][dubious – discuss], It was initially described by Georges Cuvier in 1829 as Ibis molucca. Such behaviour, together with their propensity to build nests in "inappropriate" places, and competition with captive animals, led to surplus birds being relocated from Healesville Sanctuary to Sale. Ibis respond to the cycles of climate by adapting and breeding when conditions are right and are known to be heavily reliant upon flood waters of inland rivers. Although Australian White Ibises are becoming more common in some areas, their abundance is decreasing in their natural range. [10] They again recommended the recognition of molucca at species level. You have reached the end of the page. These previously undocumented behaviours became closely associated with the urban Sydney flocks that emerged from around 1980 onwards, directly across the harbour in the Royal Botanic Gardens and the Sydney CBD, and further afield in the Centennial Parklands. [26], The Macquarie Marshes in north-western New South Wales was one of the main areas for breeding, but none has been reported breeding there since 2000, from 11,000 pairs in 1998. These species exhibit unique adaptations and/or behavioural traits that have evolved to meet the demands of a challenging and difficult environment. The male Australian White Ibis secures a pairing territory on a branch of a tall tree in order to attract a female. [23] Healesville birds also seeded a free-flying population at Currumbin Wildlife Sanctuary in Queensland. Brahminy Kites have weak feet so, although they have long, sharp curved claws, they cannot take large prey. [24], The urban population further increased after a further period of inland drought in 1998.

The White Ibis is great at aerating the soil in your lawn, local park and playing field while they're digging around for insects with their long beaks. [2], Questions surrounding the origins of recent highly urbanised and closely human-habituated populations of the species are complicated by the establishment of free flying exhibit flocks of formerly captive birds at a number of zoos and wildlife parks, including Sydney's Taronga Zoo, which first acquired birds for this purpose around 1971. This has led to concern that ibis may transmit pathogens that threaten public health or food production. [6] The species is absent from Tasmania.[27]. Some Australian White Ibis populations have learnt to exploit artificial foods in urban environments and are becoming pests. The Great Cormorant is almost entirely black in plumage, apart from a white and yellow chin and a small white patch on each thigh (absent in winter). The Straw-necked Ibis forms large breeding colonies, often with Australian White Ibises. Once the pair bond is cemented, the birds fly off to build a nest at another location. [14] The body plumage is white although it may become brown-stained. In this section, there's a wealth of information about our collections of scientific specimens and cultural objects.
