How many baby Four-horned antelopes are in a litter?
A Four-horned antelope (Tetracerus quadricornis) usually gives birth to around 1 babies.
Each of those little ones spend around 207 days as a fetus before they are released into the wild. Upon birth, they weight 1.04 kg (2.29 lbs) and measure 36.8 cm (1′ 3″). They are a member of the Bovidae family (genus: Tetracerus). An adult Four-horned antelope grows up to a size of 100 cm (3′ 4″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
The four-horned antelope (Tetracerus quadricornis), or chousingha, is a small antelope found in India and Nepal. This antelope has four horns, which distinguish it from most other bovids, which have two horns (sparing a few such as the Jacob sheep). The sole member of the genus Tetracerus, the species was first described by French zoologist Henri Marie Ducrotay de Blainville in 1816. Three subspecies are recognised. The four-horned antelope stands nearly 55–64 centimetres (22–25 in) at the shoulder and weighs nearly 17–22 kilograms (37–49 lb). Slender with thin legs and a short tail, the four-horned antelope has a yellowish brown to reddish coat. One pair of horns is located between the ears, and the other on the forehead. The posterior horns are always longer than the anterior horns, which might be mere fur-covered studs. While the posterior horns measure 8–12 centimetres (3.1–4.7 in), the anterior ones are 2–5 centimetres (0.79–1.97 in) long.The four-horned antelope is diurnal (active mainly during the day). Though solitary by nature, four-horned antelopes may form loose groups of three to five –with one or more adults, sometimes accompanied by juveniles. This elusive antelope feeds on grasses, herbs, shrubs, foliage, flowers and fruits. It needs to drink water frequently; as such it stays in places near water sources. The breeding behaviour of the four-horned antelope has not been well studied. The age at which they reach sexual maturity and the season when mating occurs have not been understood well. Gestation lasts about eight months, following which one or two calves are born. They are kept concealed for the first few weeks of their birth. The young remain with the mother for about a year.Four-horned antelopes tend to inhabit areas with significant grass cover or heavy undergrowth, and avoid human settlements. Earlier common throughout deciduous forests in India, the antelope now occurs in widely disjunct, small populations. Most of the populations are in India, and lower numbers can be found in adjoining Nepal. The four-horned antelope is threatened by the loss of its natural habitat due to agricultural expansion. Moreover, the unusual four-horned skull and the horns have been a popular target for trophy hunters. The four-horned antelope is classified as Vulnerable by the International Union for the Conservation of Nature and Natural Resources (IUCN).
