Wildlife Wednesday: Japanese Macaque

Japanese macaques, or snow monkeys, are the only species of non-human primates that are found in a temperate region. They are a very interesting species and have been studied for decades. Some behaviors that these monkeys exhibit are very unique like these monkeys.

Japanese macaques are found throughout Japan. They can be found in grasslands and montane regions. the macaques will travel to different areas based on the season. They are a medium sized monkey and weigh from 22 to 66 pounds. The males are generally larger than the females. They have a short tail. The macaques have a pinkish red face and rear end. In the winter they have a thick coat and they shed it to have a lighter summer coat. Two subspecies have been identified that are based on genetics and regional differences. These monkeys are omnivorous and will eat a lot of different plants as well as insects.

One of the most common known behaviors of the snow monkey is sitting in the hots springs. These monkeys will sit in the hot springs during the winter to help stay warm. They will also sleep in huddles to help regulate body heat. another interesting behavior that was discovered only  a few decades ago was when a female washed a sweet potato with salt water. The potato had sand on it and the sea water helped clean it. It is also thought that the salt in the water added flavor to the potato. A behavior that has been observed but not entirely understood is rock play. Rock play is when a macaque picks up a rock and taps it on the ground. It will do this repeatedly. It is hypothesized that this helps develop motor skills and learning.

Japanese macaques are really neat creatures and are unique in the primate world. They face pressure from some habitat loss and feral dogs. They are common animals at zoos and a great study species. The Blank Park Zoo in Des Moines has a great troop of macaques and enclosure. The Minnesota Zoo is also getting a new macaque enclosure. Macaques are fascinating and should continue to be studied.
