What I Learned from my Observations
The stomachs of spider monkeys are blond and the rest is black or slightly brown. Spider monkeys are about the size of a 5 year old human.
These monkeys spend their time sleeping and having fun swinging around for no obvious purpose. They groom themselves constantly, but hardly ever groom each other. Spider monkeys can’t groom like apes, because they have no thumbs, and so just groom by scratching of bugs, which does not work very well and takes a long time. They are very curious and will play with garbage and other unnatural things that they have in their habitat.
Spider monkeys will scavenge for leaves, bark, stems, and roots of small bushes and trees. They will very rarely eat the leaves, stems, bark, and roots of just one tree, but instead will eat different parts of each different plant. They love bananas and lots of other fruits. They will also eat small bugs, but they will usually not look for bugs, they will just eat one if it is crawling on them or near them.
In this group of spider monkeys, they appeared to have an alpha monkey or leader. In this case it was Brownie. On a few occasions I saw other monkeys give their bananas to her. When visitors came bearing bananas and the monkeys were lined up waiting for the fruit, I observed that they would step back when Brownie came up to the fence.
Spider monkeys are able to leap a gap of nearly ten feet and when the spider monkeys want to they can be very fast. If they are not swinging extremely fast they usually will test the branch that they will be putting their weight on before they actually do. The tail of a spider monkey is extremely important and they use their tail for grooming, keeping balance, hanging from, swinging with, carrying things and much more. It is not rare for a spider monkey to fall from a tree.
Spider monkeys try to stay clean. They will clean out their teeth by chewing on leaves and then spitting them out. If they get dirt on themselves they will also rub it off.
