Quokka


True Wild Life | Quokka | The Quokka is a small macropod about the size of a domestic cat. Like other marsupials in the macropod family , the Quokka is herbivorous and mainly nocturnal. It can be found on some smaller islands off the coast of Western Australia, in particular on Rottnest Island just off Perth and Bald Island near Albany. Quokkas resemble a small wallaby, with small rounded ears, and brown or greyish fur.


In the wild, its roaming is restricted to a very small range in the South-West of Western Australia, with a number of small scattered populations on the mainland, one large population on Rottnest Island and a smaller population on Bald Island near Albany. The islands are free of foxes and cats. On Rottnest, it is common and occupies a variety of habitats ranging from semi-arid scrub to cultivated gardens.


Quokka weighs 2.5 to 5 kg and is 40 to 90 cm long with a 25 to 30 cm tail  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.


Quokka feeds at night on native grasses and the leaves of shrubs. They need drinking water, but can survive long periods without it. This is helped by the remarkable ability of the Quokka to reuse a portion of their bodies waste products. These animals breed year round, and have a gestation period of 4 months before a new joey is born. The joey lives in its mother's pouch for the first 25 weeks of its life. After leaving the pouch, the joey continues to suckle at its mother's teets for a further 10 weeks.


There were once a lot of Quokkas, but they are now in danger of extinction. They are under threat from development that has destroyed the wetlands where they live and are also threatened by other animals that have been introduced by humans. Quokkas are preyed on by cats and foxes, who are non-native animals in Australia. Their wetland habitat is also disturbed by feral pigs. While efforts are being made to protect them, it is thought that the numbers of Quokka still have not recovered.

Huon Tree Kangaroo


 
True Wild Life | Huon Tree Kangaroo | Huon Tree Kangaroo (Dendrolagus matschiei), also known as the Matschie's Tree Kangaroo is a tree kangaroo  native to the Huon Peninsula of North Eastern New Guinea. Under the IUCN classification, Huon Tree Kangaroo is endangered. With a body and head length of 20 to 32 inches, Huon Tree Kangaroo are much smaller than Australia's well-known red kangaroo. 


There is no particular season in which they breed. Gestation lasts 32 days and joeys of captive bred individuals leave the pouch after 13 ½ months. The average life span of the Huon Tree Kangaroo in the wild is unknown, but is at least 14 years. The life span of the kangaroo in a zoo is about 20 years. The Huon Tree Kangaroo can only be found on the Huon Peninsula on the northeast coast of Papua New Guinea. They live in forests that are usually foggy.Unlike other species of kangaroos, the Huon Tree Kangaroo spends most of its time living in trees. They even eat and sleep in trees.


The most distinctive trait of all tree kangaroos is the hair whorl they possess. It is a patch of hair that goes out in many directions and its location ranges from up near the shoulders all the way down to the tail. The Huon Tree Kangaroo is golden on its ventral side, lower parts of its limbs, ear edges, belly, and tail, and the rest of its body is a chestnut brown color, except for usually having a dark stripe down its back. Their faces are typically an array of yellow and white colors. The Huon Tree Kangaroos are similar in color and size to Dendrolagus dorianus, the Doria’s tree kangaroo. Huon Tree Kangaroos ears are small and bear-like looking and they do not have a good sense of hearing because of it. They have curved claws on their forelimbs and soft pads on their hind limbs that aid in their climbing ability, and they have some independent movement of their digits as well as good dexterity due to their forelimbs being able to bend a great deal.


The Huon Tree Kangaroo are mainly folivorous, eating anything from leaves, sap, insects, flowers, and nuts.  Since they eat high fiber foods, they only eat maybe about 1 to 2 hours throughout the day and the other time of the day they are resting and digesting their food. Their digestion is similar to that of the ruminants; they have a large, “tubiform forestomach”, where most of the fermentation and breakdown of tough material takes place at; in the hind stomach, there is a mucosa lining with many glands that help absorption begin here.


The Huon Tree Kangaroo lives only on the Huon Peninsula of Papua New Guinea. Usually we think of kangaroos as animals that hop around grasslands. However, Huon Tree Kangaroos are an exception. They live in forests and are more adept at climbing trees than they are at moving on land. Today, as the population on the Huon Peninsula grows, more and more of the kangaroo's precious forests are being converted into farmland. Continued habitat loss is pushing the Huon Tree Kangaroo toward the brink of extinction.

Goodfellow's Tree Kangaroo

 
True Wild Life | Goodfellow's Tree Kangaroo | Goodfellow's Tree-kangaroo also called the Ornate Tree Kangaroo, belongs to the family Macropodidae, which includes kangaroos, wallabies and their relatives. The species is native to the rainforests  of New Guinea, and the border of central Irian Jaya in Indonesia.  Under the IUCN classification, the species is listed as Endangered, which is a result of overhunting and human encroachment on their habitat.


Like other tree-kangaroos, Goodfellow's Tree-kangaroo is quite different in appearance from terrestrial kangaroos. Unlike its land dwelling cousins, its legs are not disproportionately large compared to its forelimbs which are strong and end in hooked claws for grasping tree limbs, and it has a long tail for balance. All of these features help it with a predominantly arboreal existence. Goodfellow's Tree-kangaroo has short, woolly fur, usually chestnut to red-brown in color, a gray-brown face, yellow-colored cheeks and feet; a pale belly, a long, golden brown tail, and two golden stripes on its backside.  It weighs approximately 7 kg. 


Although it feeds mainly on the leaves of the Silkwood tree, other morsels are accepted when available, including various fruits, cereals, flowers and grasses.  It has a large stomach that functions as a fermentation vat, similar to the stomachs of cows and other ruminant  herbivores, where bacteria break down fibrous leaves and grasses.


Unlike other kangaroos, Goodfellow's Tree Kangaroos like to stay in the treetops rather than hopping around on the ground. They choose to live in the treetops to protect themselves from enemies on the ground. The New Guinea Island used to be rich in nature but as it became the major exporter of lumbers and minerals, the forests were destroyed by the human. The more and more safe places to live for Goodfellow's Tree Kangaroos are now disappearing.


To make the matters worse, roads have been extended to the middle of a forest. It has made Goodfellow's Tree Kangaroos an easy prey for hunters who go after their meat. They are usually active in the morning and evening but those who live in the area where there are many people have become nocturnal. Once they chose to live in the treetops to protect themselves from the enemies; maybe now they have changed their lifestyle for fear of human, their new enemies.

Kangaroo


True Wild Life | Kangaroo | The kangaroo is a marsupial that is indigenous to Australia and and the Indonesian island of New Guinea. Although kangaroos are often seen congregating in groups, kangaroos are generally fairly solitary mammals but kangaroos are also known for being sociable animals when with other kangaroos. Kangaroos have a deep pouch on their front in which to carry their young. A baby kangaroo is called a joey. Kangaroos eat plants, nuts, berries and insects that the kangaroos rummage for in the arid wilderness.


Kangaroos are most well known for their ability to jump a phenomenal distance. The kangaroo is the largest of the marsupials, a group an animals that includes koalas and the common brushtail possum. Marsupials are distinguished by the pouch that these animals have on their bellies, in which they carry their young. There are three main species of kangaroo in existence today and these are the red kangaroo, which is the largest and most well-known of all the kangaroo species. The Eastern grey kangaroo is known to be the heaviest species of kangaroo despite the fact that the red kangaroo is taller. The western grey kangaroo can be found in large numbers and can be anywhere in colour from grey to brown. The kangaroo is the national animal and emblem of Australia.


Kangaroos have large, flat feet which the kangaroos use in order to aid their movement which the kangaroos do by hopping. Despite the fact that kangaroos do not move about in the conventional way, kangaroos can often be seen running at high speeds, generally when the kangaroo is scared or being chased by oncoming predators. Although kangaroos are not commercially farmed, wild kangaroos are often pursued by human hunters for sport, meat, fur and when farmers are conserving their grazing land for their sheep and cows. This method of sustainable hunting is said to have more health and environmental benefits than that of sheep and cattle.


The average age of a wild kangaroo tends to be less than 10 years, although some kangaroo individuals in the wild have been known to get closer to 20 years old. Kangaroos generally live to about the age of 23 when the kangaroo is in captivity.
