The wandering whistling duck (Dendrocygna arcuata) is a species of whistling duck. They inhabit tropical and subtropical Australia, the Philippines, Borneo, Indonesia, Papua New Guinea and the Pacific Islands. [2]
There are three subspecies associated with this bird, D. a. arcuata (Indonesian wandering whistling duck), D. a. australis (Australian wandering whistling duck), and D. a. pygmaea (New Britain wandering whistling duck).
Formerly named tree ducks, the wandering whistling duck has its new name because of their loud whistling calls and the whistling noise their wings make during flight. They have long necks and legs and look like a cross between a goose and a duck. They have a strong head and neck with a darker crown and hindneck. The breast contains black spotting and the feathers are mostly dark brown. They range in size from 54–60 cm in height and weigh on average 750 grams. They mainly feed on grasses, waterlilies, water plants and occasionally insects and aquatic vertebrae.
The wandering whistling duck lives in deep lagoons, flooded grasslands or dams. They enjoy the water and rarely leave the shore. They can swim and dive with ease.
Breeding occurs during the tropical wet season usually between December and May. During this time six to fifteen eggs are laid in a nest not far from water and usually in high grass or a sheltered area.
The Bininj people of western Arnhem Land call this animal djilikuybi in the Bininj Kunwok language, and hunt it for food. [3] In the Kundjeyhmi dialect, it is known as djirrbiyuk, and there is an Aboriginal outstation in Kakadu National Park which is named Djirrbiyuk after this bird. [4] In Yolŋu languages it is known as guyiyi [5] or walkuli. [6]
Kakadu National Park is a protected area in the Northern Territory of Australia, 171 km (106 mi) southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census.
The magpie goose is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. The species was once also widespread in southern Australia but disappeared from there largely due to the drainage of the wetlands where the birds once bred. Due to their importance to Aboriginal people as a seasonal food source, as subjects of recreational hunting, and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured [by] protective management".
The lesser whistling duck, also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.
The white-faced whistling duck is a whistling duck that breeds in sub-Saharan Africa and much of South America.
The fulvous whistling duck or fulvous tree duck is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields. The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents continue to protect them until they fledge around nine weeks later.
The whistling ducks or tree ducks are a subfamily, Dendrocygninae, of the duck, goose and swan family of birds, Anatidae. In other taxonomic schemes, they are considered a separate family, Dendrocygnidae. Some taxonomists list only one genus, Dendrocygna, which contains eight living species, and one undescribed extinct species from Aitutaki of the Cook Islands, but other taxonomists also list the white-backed duck under the subfamily.
The black-bellied whistling duck, formerly called the black-bellied tree duck, is a whistling duck that before 2000 bred mainly in the southernmost United States, Mexico, and tropical Central to south-central South America. It can be found year-round in much of the United States. It has been recorded in every eastern state and adjacent Canadian province. Since it is one of only two whistling duck species native to North America, it is occasionally just known as the "whistling duck" or "Mexican squealer" in the southern USA.
The spotted whistling duck is a member of the duck family Anatidae. It is also referred to as the "spotted tree duck". This duck can be found in Indonesia, New Guinea, Australia and the Philippines. Spotted ducks are also held in captive populations.
The plumed whistling duck, also called the grass whistling duck, is a whistling duck that breeds in Australia. It is a predominantly brown-coloured duck with a long neck and characteristic plumes arising from its flanks. The sexes are similar in appearance.
Terminalia ferdinandiana, most commonly known as the Kakadu plum and also called the gubinge, billygoat plum, green plum, salty plum, murunga, mador and other names, is a flowering plant in the family Combretaceae, native to Australia, widespread throughout the tropical woodlands from north-western Australia to eastern Arnhem Land. Used as a traditional bush food and bush medicine for centuries, the fruit has especially high levels of vitamin C.
Alligator Rivers is the name of an area in an Arnhem Land region of the Northern Territory of Australia, containing three rivers, the East, West, and South Alligator Rivers. It is regarded as one of the richest biological regions in Australia, with part of the region in the Kakadu National Park. It is an Important Bird Area (IBA), lying to the east of the Adelaide and Mary River Floodplains IBA. It also contains mineral deposits, especially uranium, and the Ranger Uranium Mine is located there. The area is also rich in Australian Aboriginal art, with 1500 sites. The Kakadu National Park is one of the few World Heritage sites on the list because of both its natural and human heritage values. They were explored by Lieutenant Phillip Parker King in 1820, who named them in the mistaken belief that the crocodiles in the estuaries were alligators.
Acrochordus arafurae, known by the common names Arafura file snake, elephant trunk snake, and wrinkle file snake, is an aquatic snake species found in northern Australia and New Guinea. No subspecies are currently recognized.
The brown quail, also known as the swamp quail, silver quail and Tasmanian quail, is an Australasian true quail of the family Phasianidae. It is a small, ground-dwelling bird and is native to mainland Australia, Tasmania and Papua New Guinea and has been introduced to New Zealand and Fiji. Widespread and common throughout its large range, the brown quail is evaluated as being of "least concern" by the International Union for Conservation of Nature on the IUCN Red List of Threatened Species.
The agile wallaby, also known as the sandy wallaby, is a species of wallaby found in northern Australia and southern New Guinea. It is the most common wallaby in north Australia. The agile wallaby is a sandy colour, becoming paler below. It is sometimes solitary and at other times sociable and grazes on grasses and other plants. The agile wallaby is not considered threatened.
The black wallaroo, also known as Woodward's wallaroo, is a species of macropod restricted to a small, mountainous area in Arnhem Land, Northern Territory, Australia, between South Alligator River and Nabarlek. It classified as near threatened, mostly due to its limited distribution. A large proportion of the range is protected by Kakadu National Park.
Anbangbang Billabong lies in the shadow of Burrunggui within Kakadu National Park and is a good place to view a wide range of wildlife. Large numbers of waterfowl and wading birds inhabit the billabong and many wallabies can be found grazing around the water's edge. There is a walking trail around the circumference of Anbangbang Billabong with many picnic areas.
The dusky rat is an indigenous species of rodent in the family Muridae found in Australia.
The white-throated grasswren, also known as Yirlinkirrkirr in the local language, is a species of bird in the family Maluridae. It is endemic to northern Australia, found only in West Arnhem Land, in the Northern Territory (NT).
The northern brushtail possum is a nocturnal marsupial inhabiting northern Australia. The northern brushtail possum is sometimes considered a species, however more often than not is considered a subspecies of the common brushtail possum.
Livistona humilis, the sand palm, is an Australian plant species of the family Arecaceae. It is a small, slender palm, growing to about 7 m tall and 5–8 cm dbh. It has 8 to 15 fan-shaped leaves, 30–50 cm long with petioles 40–70 cm long. It is endemic to the Top End of the Northern Territory in Australia. Genetic investigation suggests that its closest relative is Livistona inermis. This palm is fire tolerant and usually grows in environments where it is exposed to frequent fires.
