Sumatran Orangutan
>
Sumatran orangutan (Pongo abelii) is the rarest species of orangutan. Sumatran orangutans live and endemic to Sumatra, an island located in Indonesia. They are smaller than the orangutans of Borneo. Sumatran orangutans have about 4.6 feet tall and weighs 200 pounds. Females are smaller, with 3 feet tall and weighs 100 pounds.
Compared Borneo Orangutan, Sumatran orangutan prefers feed mainly fruits and insects as well. The preferred fruit including fruit banyan and jackfruit. They also eat bird eggs and small vertebrates. Sumatran Orangutan shorter in the feed at the stem of a tree.
Wild Sumatran orangutans in the swamp Suaq Balimbing observed using tools. A tree branch broke orangutans whose length is about one foot, pushing aside the branches and sharpen edges. Then he uses it to poke holes trunk tree to look for termites. They also use sticks to banging on the walls of the hive. Also, orangutans also use tools to eat fruit. When Neesia tree ripe fruit, fruit is hard, ridged skin softened until it fell open. Inside is the preferred seed of the orangutan, but their hair covered with glass fiber-like illness when ingested. Orangutan Neesia eaters will select five inch rod, skinned and then remove the feathers with it. When the fruit is clean, the monkey will eat the seeds using a rod, or fingers. Although similar swamp in Kalimantan, Borneo orangutans wild has not been seen using a tool like this.
Sumatran orangutan NHNZ filmed for her show Wild Asia: In the Realm of the Red Ape, the show demonstrates one of the orangutans using simple equipment, twigs, to reach food from difficult places. There is also a series of images of an animal using the leaf as an umbrella during a rain storm tropical
Sumatran Orangutan also prefer to dwell in the tree than his cousin from Borneo; this is probably because of predators such as the Sumatran tiger. They move from tree to tree using a swinging arm.
Life cycle
Sumatran orangutans are more social than the orangutans of Borneo. Orangutans are gathered to eat large amounts of fruit in a banyan tree. However, adult male orangutans generally avoid contact with other adult males. Rape is common among orangutans. Sub-adult males will try to mate with any female, although maybe they fail because adult females impregnated easily refuse. Adult female orangutans prefer to mate with adult males average birth period longer than the Sumatran orangutan orangutans of Borneo and is the longest average period of great apes. Sumatran orangutans give birth when they were aged about 15 years. Baby orangutans will be close to its parent to three years. Even after that, her son would still be associated with its parent. The two species of orangutans may live several decades; approximate length can exceed 50 years old. Average first breeding P. abelii is about 12.3 years without any sign of menopause.
Endemic Sumatran orangutan from Sumatra island and his life is limited in the north of the island. In the wild, Sumatran orangutans survive in the province of Nanggroe Aceh Darussalam (NAD), the northernmost tip of Sumatra. Primates are used to spread more widely, as they found more to the South in the 1800s as in Jambi and Padang. There is a small population in North Sumatra province along the border with NAD, especially in the forests of Lake Toba. Surveys in the Lake Toba only found two areas of habitat, Bukit Lawang (defined as a wildlife preserve) and Gunung Leuser National Park. In 2002, the World Conservation Union placed the species in the IUCN Red List with critical status.
Recent surveys estimate there are about 7300 Sumatran orangutans surviving in the wild. Some of them are protected in five districts in the Gunung Leuser National Park and others living in areas not protected: Aceh blocks northwest and northeast, the river Batang Toru West, East and Sidiangkat Sarulla. Breeding program was created in the Thirty Hill National Park in Jambi and Riau provinces, and generate a new population of Sumatran orangutans.
Sumatran Tiger (Panthera Tigris Sumatrae)
>
Sumatran tiger (Panthera tigris sumatrae) is only found on the island of Sumatra in Indonesia, is one of six sub-species of tigers that still survive today and are included in the classification of critical wildlife threatened with extinction (critically endangered) in the red list of endangered species is released IUCN World Conservation Institute. The wild population is estimated between 400-500 animals, especially living in national parks in Sumatra. Sophisticated genetic testing has revealed genetic markers unique, indicating that this subspecies may evolve into separate species, if managed sustainably.
Sumatran tigers are the smallest tiger subspecies. Sumatran tiger has the darkest color among all other tiger subspecies, the black pattern width and the distance is sometimes tightly attached. Male Sumatran tigers average length 92 inches from head to tail, or about 250 cm long from head to foot with the weight 300 pounds or about 140kg, while the height of adult males can reach 60 cm. Females average 78 inches in length or about 198cm and weighs 200 pounds or approximately 91 kg. Sumatran tiger stripe is thinner than other tiger subspecies. Sumatran Tiger skin color is the darkest of all tigers, ranging from the yellow-red to dark orange. This subspecies also had more beard and mane than other subspecies, especially the male tiger. Their small size makes it easier to explore the jungle. There is a membrane in between her fingers that made them able to swim fast. Tigers are known to corner their prey into the water, especially if the prey animal is a slow swimmer. Fur changed color to dark green when giving birth.
Sumatran tiger is found only on Sumatra island. This big cat can live anywhere, from lowland forests to mountain forest, and lived in many places are not protected. Only about 400 individuals live in nature reserves and national parks, and the rest scattered in other areas are cleared for agriculture, there are also approximately 250 males were reared in zoosall over the the world . Sumatran tigers face threats will lose their habitat because the area of its spread, such as blocks of lowland forest, peat and threatened mountain rain forest clearing for agricultural land and commercial plantations, as well as encroachment by logging and road construction activities. Due to the increasingly narrow habitat and decreases, the tigers were forced into areas closer to humans, where often they were killed and arrested for entering rural areas or lost due to an accidental encounter with humans.
