Classification :
Order : Primates
Family : Pongidae
Description : The Orang Utan is tail-less, with small ears and a small nose. The coat is long and soft, and reddish brown in color. The arched eyebrows are not very conspicuous, and the jaws are prominent. The head is pear-shaped, the eyes small, and the lips mobile. The arms are very long and strong, and its prehensile feet gives it a 4-handed appearance. Length of head and body averages 96 cm (38.4 inch), standing height 137 cm (54.8 inch), weight 75 kg (165 lbs); females about 80-85% of height and 50% of weight of males.
Behavior : The Orang Utan feeds mainly on fruit, especially on figs, but it also eats leaves, bark, shoots and flowers. It is arboreal, rarely descending to the ground. It usually lives a solitary life, with mothers and offspring forming the only long-term bond. The adult males live on their own, and only join a female and her young on a temporary basis for mating. There is no evidence of fighting between adult males, and they do not appear to display any territorial behavior. The gestation period lasts between 233-263 days, and the single infant is nursed for many months.
Distribution : Borneo and Sumatra
Hornbill... This is the largest Hornbill I saw in the zoo...
Great Hornbill
Scientific Name : Buceros Bicornis
Classification :
Older : Coraciiformes
Family : Bucerotidae
Description : This is a large and very distinctive bird with black plumage and large white stripes on the wings and tails, not the longest but probably the biggest, heaviest hornbill of the region. The neck is whitish yellow in coulour, the sides of the face black. As with all the Bucerotidae, the beak is large and strong, curving slightly downward with an odd structure, known as a casque, on the upper half. There are differences between males and females in the beak colouring and in the ring arround the eye as well as the eye itself. The skull of the Great Hornbill, together with the casque, weights about 320 grams ( 11 ounces). There are two subspecies - B. b. Homrai, which is about 120cm long (47"), with the beak, in the male, up to 29.5cm in length (116"), and B. b. Bicornis, which is smaller, with the male's beak reaching 25cm(10"). A related species is the Rhinoceros Hornbill (B. rhinoceros).
Behavior : It nets in hollows, like all the other species of hornbill the male bricks in the hollow, leaving just a slit through which to feed the female and young, and to eject droppings, It feeds on fruits, invertebrates and small vertebrates. Call a harsh kronk, lower pitched than Rhinoceros Hornbill and not in duet.
Distribution : South East Asia
Habitat : Forests and woods from lowlands to 1,500m, mainly in northern and hillier regions but also down to coast.
