Mexican Black howler Monkey or Alouatta pigra is a subspecies of the mantled howler, A. palliata. This subspecies is found predominantly in forests between south eastern Mexico and north eastern Peru. Typical of its species, the Mexican howler monkey has a prehensile tail, a deep jaw, and a large pharynx which it uses to make characteristically deep and resonating howls.
The Mexican Black howler monkey or Alouatta pigra has a prehensile tail, a deepest jaw with small incisors and large canines, and a large vocal box to make deep howls.
They can eat a remarkable variety of foods including leaves, flower, buds, petioles, and fruits. Their digestive system is slow and they have significantly fewer enzymes for protein and fiber digestion, but they compensate for this by selectively eating leaves with less fiber. Much of the Mexican Black howler monkey or Alouatta pigra activity is dedicated for foraging for fruit and young leaves which it can easily digest.
Mexican Black howler monkey or Alouatta pigra has compensated for its adapted digestive system by minimizing energy output as much as possible. The Mexican howler exhibits limited interaction with members of its species and very minor aggressive behavior. There is evidence of physical aggression between members of the species during migratory periods or changes in dominance.
Males, when fighting for dominance, have been observed to target juveniles, sometimes even killing them, and physically injuring older males. For a younger Mexican Black howler monkey or Alouatta pigra male to take control of a group, he must first kill the dominant male, exhibiting extensive aggression.
