The howler monkeys (genus Alouatta monotypic in subfamily Alouattinae) are among the largest of the New World monkeys. Nine species are currently recognised.

Howler monkeys range in size from 56 to 92cm, excluding their tail which can be equally as long. Like many New World monkeys, they have prehensile tails. They have a lifespan of 15 to 20 years. These monkeys are native to South and Central American forests. They live in groups of usually about 18 individuals. Threats to howler monkeys include being hunted for food and captivity. A prehensile tail is the tail of an animal that has adapted to be able to grasp and/or hold objects. ... South America South America is a continent crossed by the equator, with most of its area in the Southern Hemisphere. ... For other uses, see Central America (disambiguation). ...

As their name suggests, vocal animal communication forms an important part of their social behavior. Specifically, the name comes from their distinctive loud barking whoop they make, which can be heard over considerable distances. (As correctly pointed out by William Henry Hudson in his novel Green Mansions, "howler" is a misnomer since the male's voice sounds rather like a powerful roar; female vocalisations sound like a pig's grunt). They have an enlarged basihyal or hyoid bone which helps them make their loud sound. They are considered the loudest land animal. Unlike other New World monkeys, both male and female howler monkeys have trichromatic colour vision. Animal communication is any behaviour on the part of one animal that has an effect on the current or future behaviour of another animal. ... In biology, psychology and sociology social behavior is behavior directed towards, or taking place between, members of the same species. ... William H.

Families Cebidae Aotidae Pitheciidae Atelidae The New World monkeys are the four families of primates that are found in Central and South America: the Cebidae, Aotidae, Pitheciidae and Atelidae. ... A trichromat is an organism for which the perceptual effect of any arbitrarily chosen light from its visible spectrum can be matched by a mixture of no more than three different pure spectral lights. ...

These large, slow moving monkeys are the only folivores of the New World monkeys. Howlers eat mainly top canopy leaves, together with fruit, buds, flowers, and nuts. They move quadrapedally and do not brachiate, usually holding on to a branch with at least two hands or one hand and the tail at all times. Their prehensile tails are strong enough to support the monkey's entire body weight, although they seldom do so. The first 2 fingers of each hand are set apart and are opposable to the other three. They very seldom leave the trees. They rest about 80 percent of the time and are considered the least active of all monkeys. In Zoology, a folivore is an animal that specializes in eating leaves. ...

Howler monkeys are relatively friendly animals that live together in groups where the number of females is greater than the number of males. However, when there is a fight over food or mates or territory, they do not scratch or bite but rather yell and slap.


Howlers and humans

While seldom aggressive, howler monkeys do not take well to captivity and are of surly disposition, and hence are the only monkey in their forests not made a pet by the Native Americans [citation needed]. However, the Black Howler (Alouatta caraya) is a relatively common pet monkey in contemporary Argentina due to its gentle nature, in comparison to the capuchin monkey's aggressive tendencies, in spite of its lesser intelligence as well as the liabilities meant by the size of its droppings and the males' loud vocalisation. It has been suggested that Residential pets be merged into this article or section. ... Native Americans redirects here. ... Black Howler Monkey, Alouatta caraya, is a Howler Monkey from Argentina, Bolivia, Brazil and Paraguay, being the southernmost member of the group. ... Type species Simia capucina Linnaeus, 1758 Species Cebus capucinus Cebus albifrons Weeper uolivaceus Cebus kaapori Cebus apella Cebus libidinosus Cebus nigritus Cebus xanthosternos Cebus queirozi Tufted Capuchin (Cebus apella) The capuchins are the group of New World monkeys classified as genus Cebus. ...

Alexander von Humboldt said about howler monkeys that "their eyes, voice, and gait are indicative of melancholy", while John Lloyd Stephens described those at the Maya ruins of Cop├ín as "grave and solemn as if officiating as the guardians of consecrated ground". To the Mayas of the Classic Period, they were the divine patrons of the artisans, especially scribes and sculptors. Copan in particular is famous for its representations of Howler Monkey Gods. Two howler monkey brothers play a role in the 16th-century myth of the Maya Hero Twins included in the Popol Vuh.

Other names

Howlers are called "congos" in Nicaragua and Costa Rica. In Belize they are called "baboons", although they are not related to the primate which usually carries that name.
