context_page_description: The mantled howler, or golden-mantled howling monkey, is a species of howler monkey, a type of New World monkey, from Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its "mantled" name from the long guard hairs on its sides.
  The mantled howler is one of the largest Central American monkeys, and males can weigh up to 9.8 kg. It is the only Central American monkey that eats large quantities of leaves; it has several adaptations to this folivorous diet. Since leaves are difficult to digest and provide less energy than most foods, the mantled howler spends the majority of each day resting and sleeping. The male mantled howler has an enlarged hyoid bone, a hollow bone near the vocal cords, which amplifies the calls made by the male, and is the reason for the name "howler". Howling allows the monkeys to locate each other without expending energy on moving or risking physical confrontation.
  The mantled howler lives in groups that can have over 40 members, although groups are usually smaller.
context_section_description: The mantled howler is native to Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama and Peru. Within Honduras, Nicaragua, Costa Rica and Panama, the mantled howler is found in locations throughout the countries. In Colombia and Ecuador, it is found in a narrow corridor bordered by the Pacific Ocean to the west and the Andes Mountains to the east and also in Colombia in a small area near the Caribbean Sea close to the Panama border. In Guatemala, the mantled howler is found through the central part of the country, and into southeastern Mexico south of the Yucatán Peninsula. The mantled howler is among the most commonly seen and heard primates in many Central American national parks, including Manuel Antonio, Corcovado, Monteverde and Soberania. The mantled howler lives in several different types of forest, including secondary forest and semi-deciduous forest but is found in higher densities in older areas of forest and in areas containing evergreen forest.  The mantled howler is sympatric with another howler monkey species, the Guatemalan black howler, A. pigra, over a small part of its range, in Guatemala and Mexico near the Yucatan Peninsula.
