Dwarf cassowary

File:Dwarf Cassowary Lae.jpg

The scientific name commemorates the Australian naturalist George Bennett.{{cite book |last1=Gotch |first1=A.F. |title=Latin Names Explained. A Guide to the Scientific Classifications of Reptiles, Birds & Mammals|year= 1995 |orig-year=1979 |publisher=Facts on File |location=London|isbn=0-8160-3377-3|pages=178–179|chapter=Cassowaries}} 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. There are two recognized subspecies

• C. b. bennetti - found throughout New Guinea except the Vogelkop Peninsula, as well as Yapen Island and New Britain
• C. b. westermanni - found on the Vogelkop Peninsula

A third subspecies, Casuarius bennetti papuanus, may exist based on a specimen collected in 1875 of unknown origin.{{cite journal |last1=Perron |first1=Richard M. |title=The taxonomic status of Casuarius bennetti papuanus and C. b. westermanni |journal=Bulletin of the British Ornithologists' Club |date=19 February 2011 |volume=131 |issue=1 |page=57}} This name is sometimes applied to C. b. westermanni subspecies, and may represent a distinct species, but the taxonomy is still unresolved.

The Karam or Kalam people{{cite web |url= http://globalrecordings.net/research/dialect/3009 |title= Dialects of Papua New Guinea: Kalam |access-date= 2014-01-08 }} of the New Guinea Highlands classify bats and flying birds as one group, {{lang|kmh|yaket}}, and the cassowaries, very large, wingless, flightless birds as another, {{lang|kmh|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.{{Cite journal

John Gould first identified the dwarf cassowary from a specimen from New Britain, in 1857.

The dwarf cassowary is a large bird but is smaller than other living cassowaries (the southern cassowary and northern cassowary). It is between {{Height|cm=99 and 150}} long and weighs between {{convert|17.6|and|26|kg|lb|abbr=on}}. 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. Compared to other cassowaries, the dwarf cassowary is shorter, with a tarsi length of {{convert|24.5|cm|in|abbr=on}}, with a slightly smaller bill, at {{convert|11|to|12.2|cm|in|abbr=on}}. 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 endemic to the montane cloud forests and tropical rainforests of the island of New Guinea (divided between the countries of Indonesia and Papua New Guinea). Though the birds are primarily found on the island of New Guinea proper, they are also known from the Bismarck Archipelago (part of Papua New Guinea's Islands Region), including the islands of New Britain and New Ireland,{{Cite web |date=27 July 2024 |title=Observations • iNaturalist |url=https://www.inaturalist.org/observations?place_id=any&subview=table&taxon_id=20499 |access-date=28 July 2024 |website=iNaturalist.org}} as well as Yapen Island{{cite book |last1=Clements |first1=James |title=The Clements Checklist of the Birds of the World |edition=6th |year=2007 |publisher= Cornell University Press|location=Ithaca, New York |isbn=978-0-8014-4501-9 }} (part of Indonesia's Papua Province), at elevations of around {{convert|3300|m|ft|abbr=on|-2}} above sea level. In areas where dwarf cassowaries do not encounter the northern cassowary (Casuarius unappendiculatus) nor the southern (Casuarius casuarius) species—i.e., avoiding interspecific competition—they will naturally become more confident and forage in lowland or open forest areas. The dwarf cassowary's total population is distributed over an area of approximately {{convert|258000|km2|sqmi|abbr=on}}.

The species feeds mainly on fallen fruits or fruits that they pluck from shrubs,{{Cite web|url=https://animaldiversity.org/accounts/Casuarius_bennetti/|title = Casuarius bennetti (Dwarf cassowary)| website=Animal Diversity Web }} 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. A solitary bird, it pairs only during breeding season. It possibly undertakes seasonal migrations in part of its range.

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.{{cite web| url=http://www.birdlife.org/datazone/species/index.html?action=SpcHTMDetails.asp&sid=5&m=1 | title=Dwarf Cassowary - BirdLife Species Factsheet | access-date=6 Feb 2009 | author=BirdLife International | year=2008| work=Data Zone}}
