On this World Monkey Day, the IUCN Primate Specialist Group Section on Human-Primate Interactions celebrates the mantled howler monkey (Alouatta palliata).
The IUCN Primate Specialist Group Section on Human-Primate Interactions brings together specialist in primatology, wildlife conservation, science education, and related fields to provide advice and training to support conservation through coexistence with monkeys and other primates. Find out more about our work here.
Mantled howlers were once considered a low conservation priority, but their populations are declining and they have been reclassified as Vulnerable to Extinction on the IUCN Red List. While howler monkeys survive well in modified landscapes, they do not like to travel on the ground so are threatened by transportation infrastructure. Howlers often use power lines to cross roads, resulting in high rates of injury and mortality from electrocution.
Visit Somos Congos, a non-profit organization in Costa Rica, to learn about their work to protect the mantled howler. https://somoscongos.com/index
