About the Spix's Night Monkey
The Spix's night monkey is a small monkey. It usually weighs about one kilogram, which is like a small bag of sugar. These monkeys are special because they are the only type of New World monkeys that are active at night. This means they are nocturnal.
They have longer arms than legs. This helps them leap farther than many other monkeys. An adult monkey is usually about half a meter tall.
These monkeys move through the forest by swinging between branches. They use all four of their limbs to hold onto branches. They can also jump from one tree to another.
Social Life of Night Monkeys
Spix's night monkeys live in groups. These groups usually include a breeding pair (a mother and a father) and their young. They are monogamous, meaning the male and female stay together to raise their family.
After the baby monkeys are born, the father takes on most of the care. He holds the babies and looks after them. The mother only takes the baby when it needs to feed.
Young monkeys usually stay with their family group until they are about two and a half to three and a half years old. Sometimes, if the father is no longer with the group, the young might leave earlier. These monkeys do not groom each other very often.
Reproduction and Life Cycle
Spix's night monkeys usually give birth to one baby at a time. However, sometimes they can have twins, just like humans. The mother carries the baby inside her for about one year before it is born.
Mating and giving birth usually happen between November and January.
How Night Monkeys Communicate
These monkeys communicate in many ways. They use sounds, sights, smells, and touch.
They make different sounds for different situations. For example, if a night monkey sees a predator, it might let out a loud, high-pitched shriek to scare it away. They also sniff each other to learn about potential partners.
When a male monkey wants to show he is aggressive, he will arch his back and straighten all his limbs. If a predator is nearby, the night monkey might sway from side to side. This is to try and make the predator go away.
Baby monkeys and their mothers use a "rejection bite" as a way to communicate. This happens after feeding or when the baby is about a week old and the mother does not want contact. Fathers and their young also use this bite when the baby is around eight weeks old and contact is not wanted.
