Golden-Mantled Howler Monkey Alouatta palliata
As recently as 1996, howler monkeys were only locally distributed in the forests of Laguna de Apoyo
Nature Reserve. The crater interior along the entire northern shore of Lake Apoyo did not sustain a permanent population, excepting a small
troop which remained along the entrance road about one kilometer after entering the crater. Today, however, is much different.
Howlers can be found all through the northern sector of the crater interior today, excepting in the yards of some of the houses along the
shore.

Howler monkeys eat leaves and fruit. They leave the trees and set foot on ground only under duress.
These animals live in trees without ever touching the ground during their entire life, making their population entirely dependent on a
continuous tree canopy. The marked seasonality of tropical dry
forest, the ecosystem of the forests of Laguna de Apoyo Nature Reserve, also places an important bottleneck in howler monkey populations.
How these monkeys find appropriate food year-round is not well-understood, which is likely the reason for declines or disappearances of
howler monkeys in many areas near people throughout the region. The species found here, Alouatta palliata is now abundant in
much of the forest of Laguna de Apoyo Nature Reserve, although its population in other peri-urban areas in Nicaragua is severely
fragmented.
