Yucatan Black Howler Monkey

The Yucatan Black Howler (Alouatta pigra) is the largest of the howler monkey species and one of the largest of the New World Monkeys. It is found in Belize, Guatemala and Mexico.


Like all howlers, the Yucatan Black Howler is known for its raucous call, which is uses for communication in its low-visibility rainforest habitat. Howlers feed primarily on leaves and fruit and are arboreal by nature.

The main threats to this species are deforestation, hunting (for food and for capture as pets) and disease (yellow fever epidemics) (Reid 1997; Pavelka and Chapman 2006).

WCS previous work with Scott Silver who conducted a surveys of Black howler monkeys translocate to the Beli’s Cockscomb Bason Wildlife Sanctuary 25 years ago indicate that the effort has been a great success, with a thriving population throughout the reserve after going locally extinct 40 ears ago.
