|Scientific Name:||Alouatta palliata (Gray, 1849)|
|Infra-specific Taxa Assessed:|
|Taxonomic Notes:||The taxonomy of the howlers of Mesoamerica and the Caribbean and Pacific coasts of Colombia and Ecuador is based on Lawrence (1933), Hill (1962), Hall (1981), Froehlich and Froehlich (1986, 1987), and Cortés-Ortiz et al. (2002). Groves (2001, 2005) recognized only A. palliata (Gray, 1849) (no subspecies), A. pigra (Lawrence, 1933), and A. coibensis Thomas, 1902 (no subspecies). Rylands et al. (2006) reviewed the taxonomy and distributions of Alouatta palliata, A. coibensis and A. pigra.
Using mtDNA markers, Cortés-Ortiz et al. (2002) found that Alouatta palliata and A. coibensis comprise a very closely related and monophyletic group of mtDNA lineages. The mitochondrial DNA divergence between the nominal species A. palliata and A. coibensis is very low, showing only 0.1% sequence divergence, more than an order of magnitude fewer nucleotide substitutions than were observed between any other pair of Alouatta species. Divergence between A. palliata and A. coibensis is similar to mitochondrial DNA distances observed between geographically separated populations within each of these two species. Rylands et al. (2006) maintained the taxonomy suggested by Froehlich and Froehlich (1987) for the forms from the Azuero Peninsula (A. coibensis coibensis) and Island of Coiba (Panama) (A. c. trabeata), but it is evident that the findings of the molecular genetic analyses of Cortés-Ortiz (2002) would relegate them to synonyms of A. palliata. Groves (2001, 2005) listed A. coibensis Thomas, 1902, with trabeata Lawrence, 1933, as a junior synonym.

|Range Description:||There are five recognized subspecies:|
Alouatta palliata palliata
The range limits separating A. p. aequatorialis from A. p. palliata are not clear. Lawrence (1933) cited a specimen of A. p. palliata from Cotó, extreme western Panama, and Hill (1962, p.106) mentioned that specimens from Sevilla Island, western Panama, collected by J. H. Batty were “manifestly” A. p. palliata. Hall (1981), on the other hand, lists Sevilla Island, and Puerto Cortez, Costa Rica, as marginal records for A. p. aequatorialis. Many individuals from Panama are intermediate (Lawrence 1933). From eastern Costa Rica, at least, A. p. palliata extends through Nicaragua to northern Honduras and, according to Curdts (1993), it just extends into Guatemala to the Río Motagua and possibly along the coast a short distance to the Cabo de Tres Puntas, where it meets A. pigra. Baumgarten and Williamson (2007) found the northern most limit of A. palliata palliata in the south margin of Rio Dulce. It is not known to occur in El Salvador to the south (Burt and Stirton 1961). There are no current records of this subspecies in El Salvador, although it evidently occurred there in the past (Daugherty 1972).
Alouatta palliata mexicana
The range of A. p. mexicana extends eastward from south-eastern Mexico, provinces of Vera Cruz, Tabasco, and northern Chiapas and Oaxaca. As discussed by Smith (1970), in Tabasco A. p. mexicana meets, and is sympatric with, A. pigra in a region five miles south-east of Macuspana. García-Orduña et al. (1999) found mixed populations of the two species in small habitat fragments in Tabasco (see also Rodríguez-Luna et al. 2001). Cortés-Ortiz et al. (2003) recorded a zone of contact and possible hybridization between A. palliata mexicana and A. pigra between the ríos Grijalva and Usamacinta on the Mexico-Guatemala border. Although several published maps include its range as extending into the highlands of Chiapas and into north-central Guatemala, an ongoing study (A. Cuarón) indicates that this subspecies range is restricted to western Chiapas, central and western Tabasco, south-eastern Veracruz, and eastern Oaxaca.
Baumgarten and Williamson (2007) provide the most recent review of the limits of the distributions of Alouatta palliata and A. pigra in Central America and Mexico. They found that the highland massif of northern Central America (including the Sierra Madre de Chiapas and central highland of Guatemala) and its associated coniferous and subalpine vegetation formed a geographic barrier separating A. pigra from A. palliata, and define the southern limit of A. pigra. They discussed the two contact zones between them: the broad range of overlap north of the highland massif in Mexico over the lowlands of the states of Tabasco and Campeche, and a narrow area of contiguous, non-overlapping ranges in eastern Guatemala where the highlands extend almost to the Caribbean. In the first, the localities where parapatry has been observed include Macuspana, Tabasco (Smith 1970, Horwich and Johnson 1986), around Zapata, Tabasco (Horwich and Johnson 1986) and the northern point of the Laguna de Términos in Campeche (Serio-Silva et al. 2006). There is no geographical barrier separating the species, both occur in the same forests and on both sides of the Rio Usamacinta, for example (Cortés-Ortiz et al. 2003). In the second, the ranges are narrowly parapatric, separated by the Río Dulce and the Lago Izabal: A. palliata to the south and A. pigra to the north and west. South-west of Lake Izabal, A. pigra occurs in the highlands of the Sierra de las Minas, but not in the lowlands, occupied by A. palliata. Any past range overlap in this region will have been lost by the extensive loss of forest (the area is heavily farmed). Baumgarten (2006) found no evidence to support sympatry supposed previously by Horwich and Johnson (1986), Curdts (1993) and Silva-López et al. (1998).
Baumgarten ansd Williamson (2007) argued that A. palliata will have occurred on the Pacific side of the highland massif of northern Central America in the past. There are historical records in Mexico (Estrada and Coates-Estrada 1984), Guatemala (Handley 1950), and El Salvador (Daugherty 1972).
Alouatta palliata aequatorialis
A. p. aequatorialis occurs in Panama, from the southern limit to the range of A. p. palliata (either in western Panama or extreme eastern Costa Rica), through the Serranía del Darién (Anthony 1916, Lawrence 1933) into western Colombia, north through the basins of the Ríos Sinú and Atrato to the Caribbean coast, and south through the Serranía del Baudó (Defler 2003) and the foothills, lowlands and lower montane areas west of the Andes to the Pacific coast, through Colombia and Ecuador, just into the Tumbes and Piura region of northern Peru (Aquino and Encarnación 1994; Encarnación and Cook 1998; Tirira 2001, 2007).
Alouatta palliata coibensis
This howler monkey is known only from Coiba Island and neighbouring Jicarón, off the Pacific coast of Panama.
Alouatta palliata trabeata
This subspecies is endemic to the Azuero Peninsula, Panama (Froehlich and Froehlich 1987, Rowe 2000, Mendes-Carvajal 2005).
Native:Colombia (Colombia (mainland)); Costa Rica (Costa Rica (mainland)); Ecuador (Ecuador (mainland)); Guatemala; Honduras (Honduras (mainland)); Mexico (Campeche, Chiapas, Oaxaca, Tabasco, Veracruz); Nicaragua (Nicaragua (mainland)); Panama; Peru

|Population:||Alouatta palliata palliata|
This subspecies is known to occur in densities of 8–10 individuals/ha in fragmented habitats. In Nicaragua (Williams-Guillen, Otterstrom, Hagell, Gomez-Fuentes, 2007) and Costa Rica this subspecies is abundant.
Alouatta palliata mexicana
Although this subspecies has a very restricted range, encompassing areas of highly disturbed vegetation with extremely high rate of loss, in some fragments the subspecies may be locally common.
Alouatta palliata aequatorialis
In one study in Colombia, 20 individuals/km² were recorded near a biological station Armargal (Ramirez-Sanchez 2003). Recent faunal surveys in Utria National Park found them to be extremely rare, in areas where they were much more common in years past (H. Rubio pers. comm.). On the Osa pennisula, Costa Rica, in Corcovado National Park, densities were recorded at 0.2 groups/km² and in Golfo Dulce at 0.1/groups/km² (Carrillo et al. 2000).
Alouatta palliata trabeata
There is an observation of 430 individuals in 35 troops recorded within 355 km² of fragmented forest (Méndez-Carvajal 2005).
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species occupies a number of vegetation types and can be found in seasonal and nonseasonal forests, and in mangroves and swamps (Baumgarten and Williamson 2007). According to the last authors, A. palliata does not occur above 2,000 m, and most of its montane localities are at lower elevations.|
The howler monkeys are the large leaf-eaters of the South American primate communities. Like the spider monkeys, they are prehensile-tailed, with a naked patch of skin on the under surface at the tip. Howler monkeys have small incisors and large, sexually dimorphic canines. The molar teeth are particularly adapted for their chewing leaves through shearing. Their most characteristic feature is the deep jaws which surround the enlarged larynx and hyoid apparatus, a resonating chamber. It is with this enlarged and highly specialized voice box that they produce their howls (grunts, roars and barks). Howling sessions, usually involving the entire group, can be heard particularly in the early morning and are audible at distances of 1–2 kms (Drubbel and Gautier, 1993). The red howlers (A. seniculus, A. macconnelli, A. juara, A. puruensis, and A. sara) have the largest voice boxes and the deepest roars, while the Mexican, Central American and northern Colombian mantled howlers, A. palliata and A. pigra, have the smallest, and their howls are more high pitched as a result.
The Mantled Howler Monkey is exceptional in the genus in that it may form large groups of more than 40 individuals, with a number of breeding males, although group size is generally less, averaging 14. For the other species, 14 is a large group, and they can usually be seen numbering four or five or up to 11 or so individuals. In the red howlers, there is usually only one dominant male in the group (occasionally two), others being sub-adults, or juveniles, along with a harem of two to five females. Unlike the spider monkeys, and related to the large proportion of leaves in the diet (up to 50% of the annual diet), the howler monkeys generally have quite small and broadly overlapping home ranges, of 5 ha up to 45 ha, depending on the type of habitat (Neville et al. 1988). The large groups of A. palliata may have home ranges extending to 60 ha (Estrada 1982), whereas in the llanos of northern Venezuela, home ranges of A. arctoidea can be as small as 4 ha (Sekulic 1982a).
Howlers are the only New World primates which regularly include mature leaves in their diet, although softer, less fibrous, young leaves are preferred when they are available. Their folivory and ability to eat mature leaves is undoubtedly one of the keys to their wide distribution and the wide variety of vegetation types they inhabit. Mature fruit is the other important food item, especially wild figs (Ficus) in many regions, but they also eat leaf petioles, buds, flowers (sometimes seasonally very important), seeds, moss, stems and twigs, and termitaria. Red howler monkeys have also been seen to eat and lick clay at so-called “salado” sites in the Colombian Amazon (Izawa 1975). The reason for this and the consumption of soil from termitaria is still not clearly understood, but may involve the need for certain minerals, or may be due to the properties of clay which, by adsorption, can reduce the effects of toxins ingested with leaves.
The diet of A. macconnelli has been studied by Mittermeier and van Roosmalen (1981) in Suriname and more recently during a long-term study in the Nouragues Field Station in French Guiana (Julliot and Sabatier 1993; Julliot 1994b,c, 1996a,b). It feeds mainly on soft parts of many different kinds of fruits, as well as flowers and young leaves. Also included in the diet are mature leaves, immature fruits, moss, bark, and the soil of termitaria. Julliot and Sabatier (1993) recorded the use of 195 plant species from 47 families. Seeds are ingested but only rarely eaten. As a result Alouatta, like Ateles, is an important seed disperser. Julliot (1996a) found that A. macconnelli dispersed the seeds of more than 95% of more than 100 plant species (especially Sapotaceae) from which they eat fruit over the two years of her observations.
Infant Alouatta are probably born throughout the year in Suriname, but data are not yet sufficient to determine if there is a birth peak. In Suriname, newborn infants have been seen in March, April, and November, and January (Mittermeier 1977). Crockett and Rudran (1987a,b) examined seasonal variation in births in red howlers from northern Venezuela, and found that they were less frequent during the early wet season (weaning would occur at the time of greatest food shortage). The llanos forests are more seasonal, however, than in the Guianas, and it is possible that this is not the case elsewhere. Oestrus lasts 2–4 days, with intervals between oestrous periods of about 17 days. Interbirth intervals are generally about 16.6 months, although they may be shortened by the death of an infant to about 10.5 months (Crockett and Sekulic 1984).
Size (see Glander (2006) for a discussion of body weight in mantled howling monkeys):
Adult male weight 7.15 kg (n=110+) (Peres 1994)
Adult female weight 5.35 kg (n=177+) (Peres 1994).
Adult male weight 6.53 kg (n=14) (Glander et al. 1991)
Adult female weight 5.35 kg (n=18) (Glander et al. 1991).
Adult male weight 7.8 kg (n=15) (Thorington Jr. et al. 1979)
Adult female weight 6.6 kg (n=15) (Thorington Jr. et al. 1979)
See Glander (2006) for a discussion of body weight in mantled howling monkeys.
Across its range, there are no major threats, although it is certainly susceptible to hunting and habitat loss. For example, forests on the Azuero Peninsula (the range of A. p. trabeata) have been largely destroyed and are highly fragmented. Likewise, habitat within the range of A. p. mexicana are known to have experienced very high rates of decline (Cuarón 1997).
In the Chocó region of Colombia, Alouatta palliata aequatorialis is at risk of widespread hunting by Afro-Colombian and indigenous people. Furthermore, over 90% of forests on the Atlantic coast of Colombia have been destroyed for agricultural and pasture; it is estimated that at least 31% of forest has been lost over the past 10 years alone (based on calculations from satellite photos; Miller et al. 2004). Ground truthing of this data found only 2.5% of viable secondary forest habitat remaining in this region (Miller et al. 2004).
