Biogeographic Regions: neotropical (Native )
Coati upper parts are dark brown, gray, or dark or brightly rust colored. The underparts are white. The head is narrow with the nose slightly turned upward and elongated, and is very flexible, allowing coaties to search out food under leaf litter and overturned debris. The muzzle is brown with pale spots above, below, and behind the eye. The ears are small and fringed with white on the inside rims. The long tails of coatis are used for balance, and are black to brown with yellow rings. Coatis have thick, dull fur. The young are not as darkly colored as adults. Adults measure 41 to 67 cm from head to the base of the tail, with the tail adding an additional 32 to 69 cm to their length. These animals are about 30 cm tall at the shoulder, and weigh between 3 and 6 kg. Coatis have strong claws and forelimbs to climb and dig out food from under rotted logs. They can reverse the joints of the anklebone to descend trees headfirst. (Marwell Zoological Park, 1996; Emmons, 1997; Kalasinkas, 1999)

Sierra Madre Occidental Pine-oak Forests Habitat
This taxon is found in the Sierra Madre Occidental pine-oak forests ecoregion, which boasts some of the richest biodiversity anywhere in North America, and contains about two thirds of the standing timber in Mexico. Twenty-three different species of pine and about 200 species of oak reside within the Sierra Madre Occidental pine-oak forests ecoregion.
Pine-oak forests here typically grow on elevations between approximately 1500 and 3300 meters, and occur as isolated habitat islands in northern areas within the Chihuahuan Desert. Soils are typically deep, where the incline allows soil build-up and derived from igneous material, although metamorphic rocks also form part of the soils in the west and northwest portions of the sierra. Steep-sloped mountains have shaped some portions of the Sierra, while others are dominated by their deep valleys, tall canyons and cliffs. These steep-sided cliffs have thinner soils limiting vegetation to chaparral types; characterized by dense clumps of Mexican Manzanita (Arctostaphylos pungens), Quercus potosina and Netleaf Oak (Q. rugosa). There are also zones of natural pasture, with grasses from the genera Arisitida, Panicum, Bromus and Stevis.
The pine-oak forests gradually transform into an oak-grassland vegetative association. Such communities represent an ecological transition between pine-oak forests and desert grasslands.. Here, species such as Chihuahuan Oak (Quercus chihuahuensis), Shin Oak (Q. grisea), Q. striatula and Emory Oak (Q. emoryi), mark a transition zone between temperate and arid environments, growing in a sparse fashion and with a well-developed herbaceous stratum resembling xeric scrub. Cacti are also part of these transition communities extending well into the woodlands. Some cacti species such as the Little Nipple Cactus (Mammillaria heyderi macdougalii), Greenflower Nipple Cactus (M. viridiflora), Mojave Mound Cactus (Echinocereus triglochidiatus), and Leding's Hedgehog Cactus (E. fendleri var. ledingii) are chiefly centered in these biotic communities. The dominant vegetation in the northernmost part of the ecoregion in the Madrean Sky Islands includes Chihuahua Pine (Pinus leiophylla), Mexican Pinyon (P. cembroides), Arizona Pine (P. arizonica), Silverleaf Oak (Quercus hypoleucoides), Arizona White Oak (Q. arizonica), Emory Oak (Q. emoryi), Netleaf Oak (Q. rugosa), Alligator Juniper (Juniperus deppeana), and Mexican Manzanita (Arctostaphylos pungens).
This ecoregion is an important area for bird richness and bird endemism. Likewise, virtually all of the ecoregion is included in the Sierra Madre Occidental and trans-mexican range Endemic Bird Area. Endemic bird species include the Thick-billed Parrot (Rhynchopsitta pachyrhyncha EN) which is in danger of extinction, with population estimates as low as 500 pairs; the Tufted Jay (Cyanocorax dickeyi NT), Eared Quetzal (Euptilptis neoxenus NT) and the Green-striped Brush Finch (Buarremon virenticeps). Temperate and tropical influences converge in this ecoregion, forming a unique and rich complex of flora and fauna. Many other birds are found in this ecoregion including the Green Parakeet (Aratinga holochlora), Eared Trogon (Euptilotis neoxenus NT), Coppery-tailed Trogon (Trogon elegans), Grey-breasted Jay (Aphelocoma ultramarina), Violet-crowned Hummingbird (Amazilia violiceps), Spotted Owl (Strix occidentalis NT), and Golden Eagle (Aguila chryaetos). Some species found only in higher montane areas are the Gould's Wild Turkey (Meleagris gallopavo mexicana), Band-tailed Pigeon (Patagioenas fasciata), Mexican Chickadee (Poecile sclateri) and Hepatic Tanager (Piranga flava).
The Sierra Madre Mantled Ground Squirrel (Spermophilus madrensis NT) is an endemic to the Sierra Madre Occidental pine-oak forests, restricted to southwestern Chihuahua, Mexico. The Mexican Gray Wolf (Canis lupus baileyi) and Mexican Grizzly Bear (Ursus horribilis), although considered by most to be extinct from this ecoregion, once roamed these mountains. Mammals also present include White-tailed Deer (Odocoileus virginianus), American Black Bear (Ursus americanus), Buller’s Chipmunk (Tamias bulleri), endemic Zacatecan Deer Mouse (Peromyscus difficilis), rock Squirrel (Spernophilis variegatus), Zacatecas Harvest Mouse (Reithrodontomys zacatecae) and Coati (Nasua nasua), to set forth a subset of mammals present.
Reptiles are also numerous in this ecoregion. Fox´s Mountain Meadow Snake (Adelophis foxi) is an endemic taxon to the ecoregion, only observed at the type locality at four kilometers east of Mil Diez, about 3.2 kilometers west of El Salto, in southwestern Durango, Mexico. There are at least six species of rattlesnakes including the Mexican Dusky Rattlesnake (Crotalis triseriatus), Mojave Rattlesnake (C. scutulatus), Rock Rattlesnake (C. lepidus), Western Diamondback Rattlesnake (C. atrox), Twin-spotted Rattlesnake (C. pricei), and Ridgenose Rattlesnakes (C. willardi). Clark's Spiny Lizard (Sceloporus clarkii) and Yarrow's Spiny Lizard (S. jarrovii), Bunchgrass Lizard (S. scalaris), and Striped Plateau Lizard (S. virgatus) are several of the lizards found in the Sierra Madre Occidental pine-oak forests.
Along springs and streams the Western Barking Frog (Craugastor augusti) and the Tarahumara Frog (Rana tamahumarae) are two anuran taxa occurring in the ecoregion. Other anuran taxa found here include: Bigfoot Leopard Frog (Lithobates megapoda), Northwest Mexico Leopard Frog (Lithobates magnaocularis) and the Blunt-toed Chirping Frog (Eleutherodactylus modestus VU). The Sacramento Mountains Salamander (Aneides hardii) is an endemic salamander found in the Sierra Madre Occidental pine-oak forests, restricted to the Sacramento Mountains, Capitan Mountains, and Sierra Blanca in Lincoln and Otero Counties within southern New Mexico, USA.

Ring-tailed coatis primarily live in forested areas; deciduous, evergreen, cloud forest, riverine gallery forest, xeric, Chaco, cerrado, and dry scrub forest habitats. Due to human influence, coatis prefer secondary forests and forest edges. They are found up to 2500 meters in elevation (Emmons, 1997; Gompper, 1998)
Range elevation: 2500 (high) m.
Habitat Regions: temperate ; tropical ; terrestrial
Terrestrial Biomes: forest ; rainforest ; scrub forest ; mountains
Habitat and Ecology
Primarily omnivorous, coatis usually seek out fruits and invertebrates. Coatis eat palms, eggs, larval beetles, scorpions, centipedes, spiders, ants, termites, lizards, small mammals, rodents, and carrion when it is available. They infrequently take chickens (Gompper, 1998; Kasalinkas, 1999; Nowak, 1991).
Animal Foods: birds; mammals; reptiles; eggs; carrion ; insects; terrestrial non-insect arthropods
Plant Foods: leaves; fruit
Primary Diet: omnivore
Coatis help to control pest populations through their foraging behavior. They provide food to predators, and are likely important in dispersing some seeds.
Coatis seem to prefer edges and secondary forest habitats, possibly due to human interactions (Gompper, 1998; Kasalinkas, 1999). They have a wide variety of predators, most notably large cats.

Life History and Behavior
Perception Channels: tactile ; chemical
One captive coati was reported to be still alive after 17 years and 8 months. In the wild, coatis only live for about 7 to 8 years (Nowak, 1991; Kasalinkas,1999).
Status: wild: 7 to 8 years.
Status: captivity: 17.5 (high) years.
Status: captivity: 17.7 years.
Status: wild: 14.0 years.
Lifespan, longevity, and ageing
Typically, one male is accepted into a band of females and juveniles near the beginning of the breeding season. The mating system is polygynous, with that male mating the females in the band. (Nowak, 1991)
Mating System: polygynous
Breeding season for coatis varies with location, and corresponds with the maximum availability of fruit. Occurs between January and March in some locations, and between October and February in others. Males will join the losely organized bands of females to mate. After mating, males leave the bands for a mainly solitary existence, and the females disperse and build tree nests for the remainder of gestation and parturation. Females give birth to litters of 3 to 7 young 74 to 77 days after mating. Most births occur between April and June Five to six weeks after birth, the females and their young will rejoin the band. (Marwell Zoological Park 1996, Emmons, 1997; Gompper, 1998; Kasalinkas, 1999; Nowak, 1991)
Young are altricial. Neonates weigh 78 g at 5 days. Eyes open at 10 days. Young coatis are able to stand at 19 days. By 24 days of age, coatis are able to walk and to focus their eyes. Young can climb at 26 days, and eat solid food at 4 months. Females become sexually mature at 2 years of age, and male mature sexually around three years of age. (Marwell Zoological Park, 1996; Gompper, 1998; Kalasinkas, 1999)

Relevance to Humans and Ecosystems
They cause damage to crops, and household damage in villages. They have also been known to take poultry. (Marwell Zoological Park, 1996; Kasalinkas, 1999; Nowak, 1991).
Negative Impacts: crop pest; household pest
Hunted by local populations for food, coatis are also vital in helping control populations of insects. There is a small demand for these animals in the live pet trade. (Marwell Zoological Park, 1996; Emmons, 1997; Gompper, 1998)
Positive Impacts: pet trade ; food ; ecotourism ; research and education; controls pest population
