If you’ve been checking out my posts for a while, you know that the black-crested macaques are one of my favorite subjects. They are listed as critically endangered, having lost 80% of their population in the last 40 years. This one seems to be contemplating that fact. The reason for the population decline is mainly due to habitat loss. They live only in Tangkoko National Park on the northern tip of the island of Sulawesi in Indonesia.
