Overview of the Natural History of howler
Howler monkeys are diurnal mammals with prehensile tail, and herbivorous arboreal habits in your diet, which congregate in small permanent social groupscalled "troops", each of these groups or troops daily moves within a restricted area of ​​land, called home range or area of ​​activity.

Howler monkeys feed on leaves, fruits and flowers of differentspecies of trees and usually are selective about the tree species used so daily travel distances in search variables. The leaves and fruit consumption is the most important in your diet, and almost40% of their time is spent eating leaves food, and 40% consumed fruits. For these arboreal primates young leaves and mature fruits are your favorite parts.


The troops males emit loud roars orhowls of which these primates derive their common name. This vocal behavior functions as a spacing mechanism troops, avoiding direct confrontations to maintain a monopoly over the resources within theirhome range.

Howler monkeys in Mexico

In the case of howler monkeys, the species A. palliata is wide geographic distribution and occurs in almost all the south of Mexico and the rest of CentralAmerica, with its representation in the northernmost region of Los Tuxtlas in southern Veracruz. In contrast, the species A. pigra, black howler monkey, is restricted geographical distribution insouthern Mexico appearing only in the states of Tabasco, Chiapas and northern Yucatan Peninsula. This species is also present in the jungles of Peten in Guatemala and Belize, and its southernmostdistribution is southern Guatemala. This restricted distribution suggests that A. pigra is a primate species endemic to the Mesoamerican region.

Our knowledge about population size, ecology and behavior forboth howler species present in Mexico is generally poor. However, in the case of species A. pigra, information on these parameters is negligible. Such vacuum and the endemic nature aulladoro black...
