of communication come in the form of mounting to show strength, branch shaking to scare off, lip-smacking as a friendly greeting, or yawning with a grimace to indicate dominance. Lion-tailed macaque behavior is characterized by typical patterns of arboreal living. This patterns involve selectively feeding on a large variety of fruit trees, large interindividual spaces while foraging, and time budgets with high proportion of time devoted to exploration and feeding. Lion-tailed macaques are omnivores, primarily eating indigenous fruits, seeds, flowers, insects, snails, and small vertebrates in virgin forest. Lion-tailed macaques are very important for seed dispersal, and are able to transport seeds long distances by either dropping or defecating seeds. However, due to changes in their environment, adaption to rapid environmental change has occurred in areas of massive selective logging through behavioral modifications and broadening of food choices. These changes involve a large increase in ground foraging and feeding on far more non-native plants and insects. These feeding changes include fruits, seeds, shoots, pith, flowers, cones, mesocarp, and other parts of many non-indigenous and pioneer plants. In the forests of Kerala they were observed preying on nestlings and eggs of pigeons. Gestation lasts approximately six months. The young are nursed for one year. Sexual maturity is reached at four years for females, and six years for males. The life expectancy in the wild is approximately 20 years, while in captivity is up to 30 years. Threats While lion-tailed macaques are preyed on by snakes, raptors, and large carnivores, the impact of natural predators on population size doesn’t compare to their largest threat. The largest threat to the lion-tailed macaque is habitat fragmentation due to large amounts of timber harvesting and exotic plantations, such as tea and coffee. This fragmentation leads to many issues that the lion-tailed macaques are facing. They are struggling to find food, being hit by cars, and being electrocuted by power lines. Due to their low numbers and high levels of fragmentation, they are also highly susceptible to inbreeding, which can cause many genetic issues. Their second largest threat is from humans hunting and trapping them for meat, especially within areas that have primates as their preferred food. There are also many human-primate conflicts occurring now due to macaques venturing out of their forests to find food. Conservation and Population An assessment in 2003 for IUCN reports 3000–3500 of these animals live scattered over several areas in
