The '''Eastern Quoll''' (''Dasyurus viverrinus''), also known as the '''Eastern Native Cat''', is a medium-sized [[carnivorous]] [[dasyurid]] [[marsupial]] native to [[Australia]].  They are now considered extinct on the mainland, but remain widespread and even locally common in [[Tasmania]]. It is one of six extant species of [[quoll]].
  
−
The '''Quokka''' (''Setonix brachyurus''), the only member of the genus '''''Setonix''''', is a small [[macropod]] about the size of a large domestic cat. Like other [[marsupial]]s in the macropod family (such as the [[kangaroo]]s and [[Wallaby|wallabies]]), the Quokka is herbivorous and mainly nocturnal.

==Ecology==
+
The Eastern Quoll is generally about the size of a small [[domestic cat]], with an adult male averaging 60cm and weighing approximately 1.3kg. Their thick coat is covered by white spots, and ranges in colour from a light fawn to a near black, with an off-white belly. They can be distinguished from the [[Tiger Quoll]] by their slender build, pointed snout and lack of spots on the tail.
−
In the wild, its roaming is restricted to a very small range in the South-West of Western Australia. The Quokka has become rare, but remains a protected species on two islands off the coast of that area, [[Bald Island]], [[Rottnest Island]], [[Garden Island (Western Australia)|Garden Island]] and rarely [[Penguin Island (Western Australia)|Penguin Island]]. Both islands are free of foxes and cats. On Rottnest Island, it is common and occupies a wide range of habitats, ranging from semi-arid scrub to cultivated gardens.
 
−
 
 
−
==Description==
 
−
It weighs 2.5 to 5kg and is 40 to 54 cm long with a 25 to 30 cm tail &mdash; which is rather short for a macropod. It has a stocky build, rounded ears, and a short, broad head. Although looking rather like a very small, dumpy kangaroo, it can climb small trees and shrubs. Its coarse fur is a grizzled brown colour, fading to buff underneath. The Quokka recycles a small amount of its waste products.
 
−
 
 
−
==Behaviour==
 
−
The Quokka is gregarious and gathers in large groups where food is available: primary items are [[Poaceae|grasses]], [[Cyperaceae|sedges]], [[Succulent plant|succulents]] and foliage. The health of some animals has suffered significantly by the ingestion of inappropriate foods, such as bread, given by well meaning visitors to Rottnest Island. Visitors are now asked to refrain from feeding them. It breeds at any time on the mainland, but in late summer on Rottnest. The Quokka only produces a single [[joey (marsupial)|joey]] in a year. Restricted availability of the [[Micromineral|trace element]] [[copper]] appears to be a major limiting factor of the ability of the Quokka to breed on Rottnest.
 
−
 
 
−
The Quokka's movements are similar to a kangaroo, using mixture of small and large hops.
 
−
 
 
−
==Interaction with Humans==
 
  
−
The Quokka has no fear of humans and it is common for it to hop up close enough to humans to be petted, particularly on Rottnest Island. It is, however, illegal to handle the animals in any way. A AUD100 fine is a commonly issued penalty for doing so.{{fact|date=December 2007}}
+
== Behaviour ==
 +
The Eastern Quoll is a solitary predator, hunting at night for its prey of insects and small mammals. They have also been known to scavenge food from the much larger [[Tasmanian Devil]].
  
−
Quokkas are occasionally abused or killed in sadistic "sports" called "Quokka Soccer."<ref>http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2003/01/12/wquok12.xml</ref> In a variant on this barbaric practice, quokkas are occasionally beaten to death with heavy sticks in "quokka hockey."
+
The breeding season begins in early winter, and the female gives birth to up to 30 young. Of these, the first to attach themselves to the six teats will be the only survivors.  Weaning takes place at about 10 weeks of age, with the young staying in the den whilst the mother forages.

−
Although numerous on the small offshore islands, it has a very restricted range and is classified as vulnerable. On the mainland, where it is threatened by introduced predatory species such as foxes, it requires dense ground cover for refuge. This refuge and habitat has been taken away from the Quokka by agricultural development, and this has contributed to the decline of the Quokka as well. Also, human-introduced cats and dogs, as well as dingoes, have contributed to the problem, as has the clearing and burning of the remaining swamplands the Quokka have left.
+
The main threats to the Eastern Quoll are competition and predation from feral cats and illegal poisoning and trapping.  The lack of [[fox]]es and [[dingo]]es in Tasmania is believed to have contributed to the survival of the species.

The Quokka was one of the first Australian mammals seen by Europeans. The Dutch mariner Samuel Volckertzoon wrote of sighting "a wild cat" on Rottnest Island in 1658. In 1696 [[Willem de Vlamingh]] mistook them for rats and named the island "Rottenest", Dutch for "rat nest".

Template:Taxobox The Eastern Quoll (Dasyurus viverrinus), also known as the Eastern Native Cat, is a medium-sized carnivorous dasyurid marsupial native to Australia. They are now considered extinct on the mainland, but remain widespread and even locally common in Tasmania. It is one of six extant species of quoll.

Description

Illustration of an Eastern Quoll by Brehms Tierleben.

The Eastern Quoll is generally about the size of a small domestic cat, with an adult male averaging 60cm and weighing approximately 1.3kg. Their thick coat is covered by white spots, and ranges in colour from a light fawn to a near black, with an off-white belly. They can be distinguished from the Tiger Quoll by their slender build, pointed snout and lack of spots on the tail.

Behaviour

The Eastern Quoll is a solitary predator, hunting at night for its prey of insects and small mammals. They have also been known to scavenge food from the much larger Tasmanian Devil.

The breeding season begins in early winter, and the female gives birth to up to 30 young. Of these, the first to attach themselves to the six teats will be the only survivors. Weaning takes place at about 10 weeks of age, with the young staying in the den whilst the mother forages.

Threats

A black eastern quoll photographed in Tasmania.

The main threats to the Eastern Quoll are competition and predation from feral cats and illegal poisoning and trapping. The lack of foxes and dingoes in Tasmania is believed to have contributed to the survival of the species.

Mainland extinction

The last mainland Eastern Quoll specimen was collected as roadkill in Sydney's Nielsen Park, Vaucluse on 31 January 1963.& The National Parks and Wildlife service reports numerous unconfirmed sightings up until 1999 (the year of the report),& and the species was reported sighted as recently as 2006.& sexy!!!!!!!!!!

Classification

The Eastern Quoll is a member of the family Dasyuridae, which includes most carnivorous marsupials. Its species name, viverrinus, indicatest that it is "ferret-like".& The species was first described in 1800 by George Shaw, who placed it in the opossum genus Didelphis, along with the only other than-known quoll, the Tiger Quoll.
