The dwarf cassowary (Casuarius bennetti), also known as Bennett's cassowary, little cassowary, mountain cassowary [2] or muruk, is the smallest of the three extant species of cassowaries.
The scientific name commemorates the Australian naturalist George Bennett. [4] He was the first scientist to examine these birds after a few were brought to Australia aboard a ship. Recognising them as a new species of cassowary, he sent specimens back to England, where other taxonomists confirmed his perception. On the west side of Cenderawasih Bay, western Papua, there is a distinctive form that may merit a split. C. papuanus is the tentative name. [2] There are no officially recognised subspecies, however, some authors believe there should be. [5]
The Karam or Kalam people [6] of the New Guinea Highlands classify bats and flying birds as one group, yaket, and the dwarf cassowary, a very large, wingless, flightless bird as another, kobtiy. Yaket are bony with wings and fly in the air, while kobtiy are bony without wings and are terrestrial and of the forest. They distinguish kobtiy from other bony, wingless animals because kobtiy are not quadrupedal like dogs and lizards and are not limbless like snakes. [7] (See Kalam languages.)
John Gould first identified the dwarf cassowary from a specimen from New Britain, in 1857. [2]
The dwarf cassowary is a large bird but is smaller than other living cassowaries (the southern cassowary and northern cassowary). It is between 99 and 150 cm (3 ft 3 in and 4 ft 11 in) long and weighs between 17.6 and 26 kg (39 and 57 lb). [2] It is a flightless bird with hard and stiff black plumage, a low triangular casque, pink cheek and red patches of skin on its blue neck. [2] Compared to other cassowaries, the dwarf cassowary is shorter, with a tarsi length of 24.5 cm (9.6 in), with a slightly smaller bill, at 11 to 12.2 cm (4.3 to 4.8 in). [2] The feet are large and powerful, equipped with dagger-like claws on the inner toe. Both sexes are similar. Females have longer casques, brighter bare skin colour and are larger in size.
The dwarf cassowary is distributed throughout mountain forests of New Guinea, New Britain, and Yapen Island, [8] at elevations up to 3,300 m (10,800 ft). In areas without other species of cassowaries, it will live in the lowlands also. [2] Its range of occurrence range is approximately 258,000 km2 (100,000 sq mi). [9]
The species feeds mainly on fallen fruits or fruits that they pluck from shrubs, [10] and small animals and insects. Dwarf cassowaries use the crest on their head to sort through leaf litter and reveal many sources of food, such as fungi, insects, plant tissue, and small vertebrates, including lizards and frogs. [10] A solitary bird, it pairs only during breeding season. [2] It possibly undertakes seasonal migrations in part of its range. [1]
The dwarf cassowary has been classified as Near Threatened by the IUCN from 2004 to 2013 due to pressure by habitat loss, habitat degradation, being hunted for food, and often being kept in captivity. However, the species was downgraded to Least Concern in 2015, as current populations appear to be stable (although population trends remain generally unknown) and there is substantially less hunting pressure than in the past.

Cassowaries are flightless birds of the genus Casuarius in the order Casuariiformes. They are classified as ratites: flightless birds without a keel on their sternum bones. Cassowaries are native to the tropical forests of New Guinea, the Aru Islands (Maluku), and northeastern Australia.
The bird family Casuariidae has four surviving members: the three species of cassowary and the emu.
Flightless birds are birds that, through evolution, lost the ability to fly. There are over 60 extant species, including the well-known ratites and penguins. The smallest flightless bird is the Inaccessible Island rail. The largest flightless bird, which is also the largest living bird in general, is the common ostrich.
The southern cassowary, also known as double-wattled cassowary, Australian cassowary, or two-wattled cassowary, is a large flightless black bird, found in Indonesia, Papua New Guinea, and northeastern Australia. It is one of the three living species of cassowary, alongside the dwarf cassowary and the northern cassowary. It is a ratite and therefore related to the emu, ostriches, rheas and kiwi.
The Casuariiformes is an order of large flightless birds that has four surviving members: the three species of cassowary, and the only remaining species of emu. They are divided into either a single family, Casuariidae, or more typically two, with the emu splitting off into its own family, Dromaiidae.
The northern cassowary also known as the one-wattled cassowary, single-wattled cassowary, or golden-necked cassowary, is a large, stocky flightless bird of northern New Guinea. It is one of the three living species of cassowary, alongside the dwarf cassowary and the southern cassowary. It is a member of the superorder Paleognathae.
The mangrove monitor, mangrove goanna, or Western Pacific monitor lizard is a member of the monitor lizard family with a large distribution from northern Australia and New Guinea to the Moluccas and Solomon Islands. It grows to lengths of 3.5 to 4 ft. It is also known as wbl yb in the Kalam language of Papua New Guinea.
The fauna of New Guinea comprises a large number of species of mammals, reptiles, birds, fish, invertebrates and amphibians.
Blyth's hornbill, also known as the Papuan hornbill, is a large hornbill inhabiting the forest canopy in Wallacea and Melanesia. Its local name in Tok Pisin is kokomo.
A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods, and earlobes. Wattles are generally paired structures but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism. In some birds, caruncles are erectile tissue and may or may not have a feather covering.
Cerbera floribunda, commonly known as cassowary plum, grey milkwood, or rubber tree, is a plant in the family Apocynaceae which is native to the region from Sulawesi to the Solomon Islands, including north east Queensland.
Ralph Neville Hermon Bulmer was a twentieth-century ethnobiologist who worked in Papua New Guinea, particularly with the Kalam people. From 1974 he made a radical shift by changing the role of his Kalam informants and collaborators, allowing them to shape the purpose of ethnography and to make them authors rather than consultants. Bulmer's tree frog is named after him.
Kalam is a Kalam language of Papua New Guinea. It is closely related to Kobon, and shares many of the features of that language. Kalam is spoken in Middle Ramu District of Madang Province and in Mount Hagen District of Western Highlands Province.
Casuarius lydekkeri, also called the pygmy cassowary, is an extinct species of cassowary.
The karuka is a species of tree in the screwpine family (Pandanaceae) and an important regional food crop in New Guinea. The nuts are more nutritious than coconuts, and are so popular that villagers in the highlands will move their entire households closer to trees for the harvest season.
The Vogelkop–Aru lowland rain forests is a tropical moist forest ecoregion in Indonesia. The ecoregion covers the peninsular lowlands of western New Guinea, along with the Aru Islands and other nearby islands.
The Southeastern Papuan rain forests is a tropical moist forest ecoregion in southeastern New Guinea. The ecoregion covers the mountainous center and coastal lowlands of the Papuan Peninsula.
The Southern New Guinea lowland rain forests is a tropical moist forest ecoregion in southeastern New Guinea. The ecoregion covers portions of New Guinea's southern lowlands.
A casque is an anatomical feature found in some species of birds, reptiles, and amphibians. In birds, it is an enlargement of the bones of the upper mandible or the skull, either on the front of the face, or the top of the head, or both. The casque has been hypothesized to serve as a visual cue to a bird's sex, state of maturity, or social status; as reinforcement to the beak's structure; or as a resonance chamber, enhancing calls. In addition, they may be used in combat with other members of the same species, in the gathering of food, or in thermoregulation.
Xanthophyllum octandrum, commonly known as Macintyre's boxwood, false jitta, yellow boxwood or sovereignwood, is a slow-growing tree in the milkwort family Polygalaceae which has the potential to reach thousands of years of age. It is endemic to coastal northeastern Queensland, Australia.
