The taruca (Hippocamelus antisensis), also known as the Peruvian guemal, north Andean deer, north Andean huemul, northern huemul or northern guemal, is a mid sized deer species that inhabits the high regions of the Andes mountains in South America. The common name taruca means "deer" in both the Quechua and Aymara languages. The taruca is closely related to the southern guemal (H. bisulcus), the only other member of the Hippocamelus genus.
The taruca is a medium-sized deer with a heavy body. It measures 128 to 146 cm (50 to 57 in) from head to rump, with an 11 to 13 cm (4.3 to 5.1 in) tail, and stands 69 to 80 cm (27 to 31 in) tall at the shoulder. Adults weigh between 69 and 80 kg (152 and 176 lb). As with most deer, males are significantly larger than females. [3]
It has sandy brown fur over most of its body, with white patches on the underside of its head, neck, tail, and genital region, and on the inner surface of its fore-legs. While females often have a dark brown area on the forehead, facial markings are much clearer in the males. The exact patterns vary between different males, but in general there is a black mask behind the nose, and a black Y or V pattern over the forehead and snout. [3]
As other deer, only male tarucas typically grow antlers. The longer tine of a full grown male generally measures around 30 cm (12-inch). Unlike other South American deer, except for the closely related huemul, the antlers consist of just two tines which branche from the base, and with the posterior tine being the larger. Males also possess canine teeth in their upper jaw, which females usually, but not always, lack. [3]
Tarucas are found only in the Andes mountains, from central Peru, through Bolivia and extreme north-eastern Chile, and into northern Argentina.
Peru holds the largest population of tarucas in South America. In 2008 it was suggested that between 9,000 and 12,000 individuals lived across the central Andes mountains. The Huancabamba depression marks the northern limit of the species distribution. Tarucas live at altitudes ranging from 3,500 m (11,500 ft) to 5,000 m (16,000 ft), and at lower altitudes within that range, might share territory with the Peruvian whitetail deer that are also endemic to the region. In Argentina, tarucas are found at altitudes of 2,000 m (6,600 ft) to 3,000 m (9,800 ft) where they occupy grasslands marked by occasional shrubs and rocky outcrops, typically near water. [1] There are no recognised subspecies.
Tarucas are mainly found in rocky slopes, queñual forests and at puna grasslands by the side of glaciar lakes at high altitude mountain terrains. Despite living in grasslands, the taruca feeds mainly on the local bushes, shrubs, and herbs for much of the year, but supplements this diet with grasses during the rainy season. Plants commonly eaten include dwarf gentian, ragworts , lupins , senna, valerian, and clubmosses. Tarucas may also feed on agricultural crops, such as alfalfa, barley, and potato plants. [3]
Tarucas are gregarious, but do not live in stable herds, with individuals moving between groups of up to thirty members each over the course of a few days. Their populations are scattered, due to their need for relatively specialised habitats, with population densities as low as 0.15/km2 (0.39/sq mi), even away from human habitation. Individual groups are typically led by the females. [4] During the breeding season, males may compete with one another, displaying threatening behaviour by raising their forelegs one at a time and pointing their antlers towards one another. [4]
The rut lasts from May to July, during which time the deer segregate into smaller groups with a single adult male. Males drop their antlers immediately after the breeding season finishes, in September, with the new pair beginning to grow in December, and losing the velvet by February. Pregnancy lasts for 240 days, so that the single fawn is born between January and March, coinciding with the rainy season. Twins have been observed in captivity, but are rare. The mother leaves the group in order to give birth, and keeps the fawn hidden behind rocky outcrops for the first month of life. [3]
A deer or true deer is a hoofed ruminant ungulate of the family Cervidae. Cervidae is divided into subfamilies Cervinae and Capreolinae. Male deer of almost all species, as well as female reindeer, grow and shed new antlers each year. These antlers are bony extensions of the skull and are often used for combat between males.
The pudus are two species of South American deer from the genus Pudu, and are the world's smallest deer. The chevrotains are smaller, but they are not true deer. The name is a loanword from Mapudungun, the language of the indigenous Mapuche people of central Chile and south-western Argentina. The two species of pudus are the northern pudu from Venezuela, Colombia, Ecuador, and Peru, and the southern pudu from southern Chile and south-western Argentina. Pudus range in size from 32 to 44 centimeters tall, and up to 85 centimeters (33 in) long. The southern pudu is classified as near threatened, while the northern pudu is classified as Data Deficient in the IUCN Red List.
The sika deer, also known as the Northernspotted deer or the Japanese deer, is a species of deer native to much of East Asia and introduced to other parts of the world. Previously found from northern Vietnam in the south to the Russian Far East in the north, it is an uncommon species that has been extirpated in most areas of its native range, except in Japan, where it is overabundant and present in very large numbers.
The red deer is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a doe or hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of western Asia. It also inhabits the Atlas Mountains of Northern Africa; being the only living species of deer to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, the United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source.
The Cordillera Blanca is a mountain range in Peru that is part of the larger Andes range and extends for 200 kilometres (124 mi) between 8°08' and 9°58'S and 77°00' and 77°52'W, in a northwesterly direction. It includes several peaks over 6,000 metres (19,690 ft) high and 722 individual glaciers. The highest mountain in Peru, Huascarán, at 6,768 metres (22,205 ft) high, is located there.
The chital or cheetal, also known as the spotted deer, chital deer and axis deer, is a deer species native to the Indian subcontinent. It was first described and given a binomial name by German naturalist Johann Christian Polycarp Erxleben in 1777. A moderate-sized deer, male chital reach 90 cm (35 in) and females 70 cm (28 in) at the shoulder. While males weigh 70–90 kg (150–200 lb), females weigh around 40–60 kg (88–132 lb). It is sexually dimorphic; males are larger than females, and antlers are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, rump, throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly 1 m long.
Huascarán National Park is a Peruvian national park that comprises most of the mountain range known as Cordillera Blanca which is part of the central Andes, in the region of Ancash. The park covers an area of 340,000 hectares and is managed by the Peruvian Network of Protected Natural Areas, or SERNANP. It was designated as a World Heritage Site in 1985 by UNESCO, is also a well-known mountaineering spot, and harbors a unique biodiversity with plant species such as the Queen of the Andes, trees of the genera Polylepis and Buddleja, and animals such as spectacled bears, condors, vicunas, and tarucas.
Hippocamelus is a genus of Cervidae, the deer family. It comprises two extant Andean and two fossil species. The living members are commonly known as the huemul, and the taruca, also known as northern huemul.
The Rio Abiseo National Park is located in the San Martín department of Peru. UNESCO pronounced it as Natural and Cultural Heritage of Humanity in 1990. The park is home to many species of flora and fauna, as well as the location of over 30 pre-Columbian archaeological sites. Since 1986, the park has not been open to tourism due to the fragile nature of both the natural and archaeological environment.
Brockets or brocket deer are the species of deer in the genus Mazama. They are medium to small in size, and are found in the Yucatán Peninsula, Central and South America, and the island of Trinidad. Most species are primarily found in forests. They are superficially similar to the African duikers and the Asian muntjacs, but only distantly related. About 10 species of brocket deer are described.
Thorold's deer is a threatened species of deer found in the grassland, shrubland, and forest habitats, at high altitudes, of the eastern Tibetan Plateau, as well as some fragmented areas further north in central Western China. It is also known as the white-lipped deer for the white fur around its snout.
The gray brocket, also known as the brown brocket, is a species of brocket deer from northern Argentina, Bolivia, southern Peru, eastern and southern Brazil, Paraguay, and Uruguay. It formerly included the Amazonian brown brocket and sometimes also the Yucatan brown brocket as subspecies. Unlike other species of brocket deer in its range, the gray brocket has a gray-brown fur without reddish tones.
The puna grassland ecoregion, part of the Andean montane grasslands and shrublands biome, is found in the central Andes Mountains of South America. It is considered one of the eight Natural Regions in Peru, but extends south, across Chile, Bolivia, and western northwest Argentina. The term puna encompasses diverse ecosystems of the high Central Andes above 3200–3400 m.
The south Andean deer, also known as the southern guemal, south Andean huemul, southern huemul, or Chilean huemul or güemul, is an endangered species of deer native to the mountains of Argentina and Chile. Along with the northern guemal or taruca, it is one of the two mid-sized deer in the Hippocamelus genus and ranges across the high mountainsides and cold valleys of the Andes. The distribution and habitat, behaviour, and diet of the deer have all been the subject of study. The viability of the small remaining population is an outstanding concern to researchers.
The mountain parakeet, also known as the golden-fronted parakeet, is a species of parrot, one of two in the genus Psilopsiagon within the family Psittacidae. It is found in the Puna grassland. Its natural habitat is subtropical or tropical high-altitude shrubland. Four subspecies are recognised.
The northern pudu is a species of South American deer native to the Andes of Colombia, Venezuela, Peru and Ecuador. It is the world's smallest deer and is classified as Data Deficient in the IUCN Red List. Originally classified under genus Pudu, some authorities consider it to belong to a separate genus (Pudella) from the southern pudu, along with Pudella carlae.
The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals. The Capreolinae are believed to have originated in the Middle Miocene, between 7.7 and 11.5 million years ago, in Central Asia.
Odocoileus lucasi, known commonly as the American mountain deer, is an extinct species of North American deer.
The Eastern Cordillera Real montane forests (NT0121) is an ecoregion in the eastern range of the Andes of southern Colombia, Ecuador and northern Peru. The ecoregion covers the eastern slopes of the Andes, and includes montane forest that rises from the Amazonian rain forest, with cloud forest and elfin forest at higher elevations. It is rich in species, including many endemics. It is threatened by logging and conversion for pasturage and subsistence agriculture.
Distichia muscoides is a species of plant in the rush family Juncaceae. It is native to the Andes of South America where it grows in upland wetland areas known as bofedales.
