Perception Channels: tactile ; chemical
The main predators of Collared Peccaries are humans, coyotes, pumas, jaguars, and bobcats. For centuries, young Peccaries have been captured, kept as domestic pets, and even fattened by Central and South American Indians. In Peru, 10,000 skins have been exported annually for decades. In Texas, more than 20,000 individuals are shot during the hunting season. Populations are fairly resilient due to adaptability, although subspecies in the tropics are threatened by rainforest destruction.
IUCN Red List of Threatened Species: least concern
Collared Peccaries have readily habituated urban environments, and often frequent locations where they know they will be fed. Thus, they are potential nuisances.
Collared Peccaries have for decades been a source of economic income due to their skins and as hunting trophies. They are among the most important big game species in Arizona. The young are often captured and serve as domestic farm animals.
Collared Peccaries are primarily herbivorous, and have complex stomachs for digesting coarsely-chewed food. In its southern range, this species eats a variety of foods, including roots, bulbs, fungi, and nuts, in addition to fruits and occasional eggs, carrion, snakes, fish, and frogs. In the northern range, Collared Peccaries eats more herbivorous foods, such as roots, bulbs, beans, nuts, berries, grass, and cacti. Despite all this supplementary diet, the main dietary components of this species are agaves and prickly pears. The prickly pear is ideal in the Javelina's arid range due to its high water content. This species is also capable of eating cultivated planted by humans.
Collared Peccaries are found in the Nearctic and Neotropical regions. The 14 subspecies occur from northern Argentina in South America, throughout Central America, and have spread into the southern Arizona, New Mexico, and Texas in the United States.
Biogeographic Regions: nearctic (Native ); neotropical (Native )
In South and Central America, the Collared Peccary inhabits tropical rainforests. In the southern United States, herds occur in Saguaro deserts, where they prefer mesquite habitats with an abundance of prickly pear cacti. Collared Peccaries have also become common in residential areas, where they may rely on human handouts for food.

Average lifespan
Status: captivity: 31.5 years.
Shoulder height: 0.3 to 0.5 m Length: 0.8 to 1.0 m. Weight: 15 to 25 kg. Collared Peccaries are often confused with pigs due to their appearance. Their coat is a grizzled grayish black throughout, except for a yellowish tinge on the cheeks and a whitish to yellowish collar extending the mane, over the shoulders, and to the throat. While males and females are very similar in size and color, young are a yellowish brown color, with a black stripe down the back. Collared Peccaries have short, straight tusks that fit together tightly enough to hone eachother down with every jaw movement. This razor sharpness gives this species its common name: Javelina: a javelin is a lightweight, tip-shaped spear. Javelinas have a distinct dorsal gland on the rump that is essential in much species-specific behavior. They also have poor eyesight and good hearing, which are believed to contribute to the very vocal nature of this species.

A designated or specific breeding season does not prevail in Collared Peccary herds; rather, mating reflects climate, especially rain, and occurs throughout the year. More young are raised in rainy years. The dominant male does virtually all the breeding. Subordinate males do not have to leave the herd, but are not allowed to approach females in estrus. As a result, bachelor herds do not exist. 1 to 3, but rarely 4, young are born after a gestation period of 141 to 151 days. Birthing mothers retreat from the group; the newborn might otherwise be eaten by other group members. However, mothers rejoin the herd 1 day after giving birth. Only the older sisters of the newborn are tolerated with the young; these often become nursemaids for the new mother. Weaning occurs at 2 to 3 months. Males reach sexual maturity at 11 months; females, at 8 to 14 months. Despite the high mortality rate in this species, members have a life span of up to 24 years, which was observed in captivity.

The collared peccary (Dicotyles tajacu) is a species of artiodactyl (even-toed) mammal in the family Tayassuidae found in North, Central, and South America. It is the only member of the genus Dicotyles. They are commonly referred to as javelina, saíno, or báquiro, although these terms are also used to describe other species in the family. The species is also known as the musk hog. In Trinidad, it is colloquially known as quenk.[3]
Although somewhat related to true Old World pigs, and frequently referred to as a pig, this species and the other peccaries are no longer classified in the pig family, Suidae. Although formerly classified in the genus Pecari, studies in 2020 placed them in the genus Dicotyles, based on an unequivocal type-species selection; these studies have been accepted by the American Society of Mammalogists.[4][5] Currently, the IUCN still places them in the genus Pecari.
The collared peccary stands around 510–610 mm (20–24 in) tall at the shoulder and is about 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) long. It weighs between 16 and 27 kg (35 and 60 lb).[6] The dental formula is: 2/3,1/1,3/3,3/3.[7] The collared peccary has small tusks that point toward the ground when the animal is upright. It has slender legs with a robust or stocky body. The tail is often hidden in the coarse fur of the peccary.[8]
The collared peccary is widespread throughout much of the tropical and subtropical Americas, ranging from the Southwestern United States to northern Argentina. They were reintroduced to Uruguay in 2017, after 100 years of extirpation there.[9] The only Caribbean island where it is native, however, is Trinidad. Until fairly recently, it was also present on the nearby island of Tobago, but is now exceedingly rare (if not extirpated) due to overhunting by humans. An adaptable species, it inhabits deserts, xeric shrublands, tropical and subtropical grasslands, savannas, shrublands, flooded grasslands and savannas, tropical and subtropical dry broadleaf forests, and several other habitats; it is also present in habitats shared by humans, merely requiring sufficient cover. Peccaries can be found in cities and agricultural land throughout their range, where they consume garden plants. Notable populations are known to exist in the suburbs of Phoenix and Tucson, Arizona.[10][11]
Due to the lack of fossil material or even specimens from archeological sites, it was assumed that javelinas only recently crossed into the US by way of Mexico. However, a fossil jaw of this species was discovered in Florida ("Collared peccary (Mammalia, Artiodactyla, Tayassuidae, Pecari) from the late Pleistocene of Florida", Richard C. Hulbert, Gary S. Morgan & Andreas Kerner), proving that at some point in the late Pleistocene the species had already inhabited part of the Southern US.
Collared peccaries are often classified as herbivores. They normally feed on cactus, mesquite beans, fruits, berries,[12] seeds,[3] roots, tubers, bulbs,[12] palm nuts, grasses,[12] other green vegetation, fungi,[12] and insects.[3] However, they will also eat eggs, snakes, fish, frogs,[12] lizards, dead birds, and rodents if the opportunity presents itself.[13] Despite all this supplementary diet, the main dietary components of this species are agaves and prickly pears.[12] In areas inhabited by humans, they also consume cultivated crops and ornamental plants, such as tulip bulbs.[10][11]
The main predators of the collared peccary are cougars (Puma concolor), Mexican wolves (Canis lupus baileyi), coyotes (Canis latrans), jaguars (Panthera onca), and bobcats (Lynx rufus).[14]
Collared peccaries are diurnal creatures that live in groups of up to 50 individuals, averaging between six and nine animals. They sleep in burrows (often under bushes or larger systems of tree roots), but sometimes can be found in caves, abandoned mines, old desert tunnels, or among logs, felled trees and abandoned timber.[8] However, collared peccaries are not completely diurnal. In central Arizona, they are often more active at night, and less so in the heat of the daytime.
Although they usually ignore humans, they will react if they feel threatened. They defend themselves with their tusks. A collared peccary can release a strong musk or give a sharp bark if it is alarmed.[8] Amazonian peoples (including the Shipibos) sometimes raise and tame juvenile collared peccaries, if they are encountered.
Peccary will also rub their scent onto rocks and tree stumps to mark their territory, and rub the scent on each other to help with identification.[13]
The giant peccary (described as Pecari maximus) was a purported fourth species of peccary, first reported to have been seen in Brazil in 2000 by Dutch naturalist Marc van Roosmalen. In 2003 German natural history filmmaker Lothar Frenz filmed a group and gathered a skull which later served as the type (INPA4272). It had been known locally as caitetú-mundè, which Roosmalen et al. state the locals claimed was Tupí and meant "the collared peccary that is bigger and goes in pairs", as opposed to caitetú-de-bando, "the collared peccary that goes in herds". It was formally described in 2007,[15] but the scientific evidence for its species status was quickly questioned,[16][17] which also was one of the reasons for its initial evaluation as data deficient by IUCN in 2008.[18] A review in 2011 moved the giant peccary into synonymy with the collared peccary (P. tajacu),[19] which was followed by the IUCN the same year.[20]
The reported range of the giant peccary encompasses the south-central Amazon between the Madeira and the Tapajós Rivers and northern Bolivia.[21] It is restricted to terra firme forest, which is forest that does not flood annually. Unlike other peccaries in its range, the giant peccary was reported to mainly occur in pairs or small family groups.[15]
According to its original description, the giant peccary is larger, longer-legged, and proportionally smaller-headed than the only other member of the genus, the collared peccary.[15] Compared to most individuals of the sympatric populations of the collared peccary, the giant peccary also had thinner fur that is grizzled in brown and white, blacker legs, and a relatively faint collar. Five skins of the giant peccary had a total length of 120–137 cm (47–54 in), while local hunters have estimated a weight of 40–50 kg (88–110 lb). Based on a mtDNA study, the collared and the giant peccaries were estimated to have diverged 1.0–1.2 million years ago, but these results were later questioned due to the small sample size, low bootstrap support, and the absence of nDNA and cytogenetic results.[16][20]
In 2011, a review noted that the measurements provided in the initial description were within those generally recognized for the collared peccary, and the behaviors supposedly unique to the giant peccary are also known from the collared peccary.[19] They also provided new genetic evidence showing that collared peccaries from South America form a monophyletic clade that includes the giant peccary (without it the clade is paraphyletic). The major genetic split within the collared peccary is between a clade comprising North and Central American specimens, and a clade comprising South American specimens (the presumed contact zone is in Colombia, which has both clades). Furthermore, extensive infraspecific variations (both individual and locality-based) are known in the morphology of the collared peccary.[20]
