Гуанако: дикий верблюд Южной Америки

Species of mammal (camelid)

The guanaco (/g//w//a://"//n//a://k//oU/ ghwuahNAHkoh; Lama guanicoe) is a camelid native to South America, closely related to the llama. Guanacos are one of two wild South American camelids; the other species is the vicuña, which lives at higher elevations.

The guanaco gets its name from the Quechua word huanaco (modern spelling wanaku). Young guanacos are called chulengos or "guanaquitos".

Guanacos stand between at the shoulder, body length of , and weigh Their color varies very little (unlike the domestic llama), ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small, straight ears. The lifespan of a guanaco can be as long as 28 years. Guanacos are one of the largest terrestrial mammals native to South America today. Other terrestrial mammalian megafauna weighing as much or more than the guanaco include the tapirs, the marsh deer, the white tailed deer, the spectacled bear, and the jaguar. Guanacos have thick skin on their necks, a trait also found in their domestic counterparts, the llama, and their relatives, the wild vicuña and domesticated alpaca. This protects their necks from predator attacks. Bolivians use the neck skin of these animals to make shoes, flattening and pounding the skin to be used for the soles. In Chile, hunting is allowed only in Tierra del Fuego, where the only population not classified as endangered in the country resides. Between 2007 and 2012, 13,200 guanacos were legally hunted in Tierra del Fuego.

Like all camels, Guanacos are herbivores, grazing on grasses, shrubs, herbs, lichens, fungi, cacti, and flowers.

Guanacos are often found at high altitudes, up to above sea level, except in Patagonia, where the southerly latitude means ice covers the vegetation at these altitudes. For guanacos to survive in the low oxygen levels found at these high altitudes, their blood is rich in red blood cells. A teaspoon of guanaco blood contains about 68 million red blood cells; four times that of a human.

Guanaco fiber is particularly prized for its soft, warm feel and is found in luxury fabric. In South America, the guanaco's soft wool is valued second only to that of vicuña wool. The pelts, particularly from the calves, are sometimes used as a substitute for red fox pelts, because the texture is difficult to differentiate. Like their domestic descendant, the llama, the guanaco is double coated with coarse guard hairs and a soft undercoat, the hairs of which are about 16–18 µ in diameter and comparable to cashmere.

Guanacos inhabit the steppes, scrublands and mountainous regions of South America. They are found in the altiplano of Peru, Bolivia and Chile, and in Patagonia, with a small population in Paraguay. Estimates, as of 2016, place their numbers around 1.5 to 2 million animals 1,225,000–1,890,000 in Argentina, 270,000–299,000 in Chile, 3,000 in Peru, 150–200 in Bolivia and 20–100 in Paraguay. This is only 3–7% of the guanaco population before the arrival of the Spanish conquistadors in South America. A small population introduced by John Hamilton exists on Staats Island in the Falkland Islands (Malvinas), with a population of around 400 as of 2003. In Torres del Paine National Park, the numbers of Guanacos increased from 175 in 1975 to 3,000 in 1993. Guanacos live in herds composed of females, their young, and a dominant male. Bachelor males form separate herds. While reproductive groups tend to remain small, often containing no more than 10 adults, bachelor herds may contain as many as 50 males. When they feel threatened, guanacos alert the herd to flee with a high pitched, bleating call. The male usually runs behind the herd to defend them. They can run at per hour, often over steep and rocky terrain. They are also excellent swimmers. A guanaco's typical lifespan is 20 to 25 years. In Bolivia, the habitat of Guanacos is found to be threatened by woody plant encroachment.

Some guanacos live in the Atacama Desert, where in some areas it has not rained for over 50 years. A mountainous coastline running parallel to the desert enables them to survive in what are called "fog oases" or lomas. Where the cool water touches the hotter land, the air above the desert is cooled, creating a fog and thus, water vapor. Winds carry the fog across the desert, where cacti catch the water droplets and lichens that cling to the cacti soak it in like a sponge. Guanacos then eat the cacti flowers and the lichens.

The guanaco is a diurnal animal. It lives in small herds consisting of one male and several females with their young. When the male detects danger, he warns the group by bleating. The guanaco can run up to This speed is important for the survival of guanacos because they cannot easily hide in the open grasslands of the Altiplano. Natural predators of the guanaco include pumas and the culpeo or Andean fox. When threatened, the guanaco alerts the rest of the herd with a high pitched bleating sound, which sounds similar to a short, sharp laugh. Though typically mild mannered, guanacos often spit when threatened, and can do so up to a distance of six feet.

Mating season occurs between November and February, during which males often fight violently to establish dominance and breeding rights. Eleven and a half months later, a single chulengo is born. Chulengos are able to walk immediately after birth. Male chulengos are chased off from the herd by the dominant male at around one year old.

Although the species is still considered wild, around 300 guanacos are in U. S. zoos, and around 200 are registered in private herds. Guanacos have long been thought to be the parent species of the domesticated llama, which was confirmed via molecular phylogenetic analysis in 2001, although the analysis also found that domestic llamas had experienced considerable cross hybridization with alpacas, which are descended from the wild vicuña. The guanaco was independently domesticated by the Mapuche of Mocha Island in southern Chile, producing the "chilihueque" which was bred for its wool and to pull the plough. This animal disappeared in the 17th century when it was replaced by Old World sheep and draft animals.
