Japanese Macaque

The troop consists of seven monkeys. One adult male, Flash, and six females including Isabelle, Yuki, Hana, Ynez, Iris and Erin. Their ages range from 25 years to the newborn. You are born into your social class. If you have a higher standing it is likely that you will get the most grooming and will eat before the others.Rankings are not stable, and can change depending on the whims of the adult male, Flash. He has the final say as the dominant male and changes may occur after the breeding season.
  
Found in the wild: Japanese macaques are the northernmost of all non-human primates and can live up to elevations of 9,600 feet above sea level. They are found in Honshu, Japan.

See Them at the Central Park Zoo: This troop of primates lives on an island in the center of the Temperate Zone, just across from the Red panda exhibit.

Description: They are Old World monkeys. Individuals have brown-gray fur, a red face, hands and bottom, and a short tail. 

Baby Zeppy, at seven months old

Zoo Snow Monkey Habitat: A large island surrounded by water. The habitat includes winter hot tubs, that reach the same temperature as the Japanese Macaques body temperature - 104 degrees, for their bathing pleasure. You will also see two black necked swans and will find freeloading Mallard Ducks, raising their ducklings seasonally. 

What do they eat:  In the wild, they will feed on seeds, roots, buds, fruit, invertebrates, berries, leaves, birds eggs, fungi, bark and cereals. Japanese macaques are omnivorous, which means they will eat just about anything- meat or vegetation. At the Central Park Zoo, the troop is fed yams, oranges, apples, green beans, mixed greens, peanuts, and monkey chow.

Life span: 30 years

Threats: Not threatened.

Fun Facts: They live in parts of Japan where it snows. They are the only animal other than humans and raccoons,  who wash their food before they eat it. These are the monkeys you may have seen that find hot springs and spend a lot of time in the winter sitting in the warm water. These monkeys are thought to be the inspiration behind the saying 'see no evil, hear no evil and speak no evil'.

Siamang

PHYSICAL CHARACTERISTICS:

The Siamang is a gibbon and like the latter, it is an ape, not a monkey. The chief characteristics distinguishing apes from monkeys are the absence of a tail, their more or less upright posture and the high development of their brain. (Gorillas, chimpanzees and orangutans are also apes.)

The Siamang is always black in color, with reddish-brown eyebrows. It differs from other gibbons in that it has a webbing between the second and third toe. The largest of the gibbon family, Siamangs are also the best at walking on two legs.

Like other gibbons, they have tough, horny pads on their buttocks known as ischial callosities. Since Siamangs and Gibbons build no sleeping nest, the pads help them spend a comfortable night seated on tree branches safe from predators.

Male and female are similar in size, growing to 30-35 inches in length and weighing approximately 23 pounds.

DISTRIBUTION and HABITAT:

Siamangs range through southeastern Asia and are found in some numbers in the Malay Peninsula and Sumatra.

BEHAVIOR:

Along with other gibbons, the Siamangs are the top trapeze artists of the animal world. They leap with confidence across formidable gaps between branches, launching themselves 30-50 feet, using their hands as hooks. This mode of locomotion is called brachiation. While their arms are used for travel, their feet are used to carry objects. When walking, Siamangs will hold their arms above their heads for balance.

Siamangs live in family groups lead by a dominant male. They are protective of one another and sociable among themselves, huddling together in groups of two or three when they sleep.

The call of the Siamang excels that of other gibbons because of the animal's sound-amplifying throat sac. The female emits a series of barks alternated with booms resonated in the vocal pouch, which she blows up like a balloon. The mate's higher scream is usually uttered at each of the two accelerations of the female, and their combined "song" rises in pitch to end with the thunderous pouch boom of the male. It is quite a display of territory and power and can be heard for a considerable distance.

DIET:

Siamangs eat fruit, leaves, insects, nuts, small animals, birds and bird's eggs. In the zoo they are fed fruit, vegetables and monkey chow.

REPRODUCTION and GROWTH:

Siamangs bear one offspring after a seven- month gestation period. At birth, the young are naked, and for the first few months, the baby clings to the mother's abdomen. She, in turn, keeps her legs partially raised to provide warmth and support. By the age of two, the baby is independent but still very much a part of the family.

Sexual maturity is reached at about seven years of age.  In the wild they live from 25 to 30 years.

ENDANGERED STATUS:

Like other gibbons, the Siamang is declining in numbers as man enters its forested territory, often killing the mothers in capturing the young for a lucrative pet market.
