When the dawn breaks in the winter, the monkeys stay on top branches of trees to get the warmth of the morning sun. Because, the whole night they had to spend under open sky in tree branches.
When it becomes slightly warm at about 6-30 A.M in the morning they start eating the green leaves of trees. It was also observed that the leaves of rubber plants are delicious to them.
Many groups of these monkeys stay only in rubber gardens and eat rubber leaves.
At noon, at around 12 to 12-30 they take rest.
It is also a time for making love. One monkey shows affection to it’s opposite counterpart and even at times they engage themselves in intercourse.
When the sun starts turning red from the dazzling yellow, the groups of spectacle monkeys start selecting their sites of stay at night.
They continue to eat leaves and cross one place to another to find the suitable place. The entire group finally come close and assembles in near by trees.
The monkeys have extreme love for their kids. Generally babies are born from the month of January to March. A one day old monkey grasps tightly his or her mother, who jumps from one tree to another. All the group members show affections to the offspring and like human being the baby is transferred from one lap to another monkey’s lap.
They become furious when any one attempts to attack their kids.
