An adorable newborn rhino calf charmed animal lovers with his first steps in public with his mum.

Basel Zoo in Switzerland released the footage as it announced that the male calf named Tarun was born on the 13th May at 11.35pm.

Its mum, 28-year-old Quetta, is doing fine, they added.

Zoo experts say baby Tarun is gaining two kilos (0.31 stone) each day. Its name comes from Sanskrit, meaning ‘young’ or ‘youth.’

Tarun is Quetta’s fifth child and the 36th rhinoceros born at Basel Zoo.

The institution coordinates the European Conservation Breeding Program (EEP).

Basel Zoo is also participating in different species protection projects initiated by the International Rhino Foundation (IRF), a charity organisation based in Fort Worth, Texas, in the United States, which focuses on the conservation of rhinos.

Basel Zoo said Quetta was 16 months – or 498 days – pregnant, adding that the name of the baby’s dad was 28-year-old Jaffna.

The zoo’s rhino keepers decided to close their rhino house for visitors for several weeks to give mum and newborn some privacy.

The ban was lifted earlier this week – to the delight of Tarun’s many new fans.

The young calf is thriving on mum’s milk which he will continue to drink for a year.

Tarun’s behaviour in his first few days has been described as “shy and reluctant.”

However, he has recently shown more courage in discovering his surrounding.

But protective mum Quetta continues to keep an eye on her newborn.

Basel Zoo’s rhino breeding programme has a long tradition. In 1956, the first Indian rhino was born at the zoo. Rudra, who died at the age of 31 in 1987, was the world’s first Indian rhino bull born in a zoo.

Basel Zoo is currently home to five Indian rhinos: Tarun’s parents Quetta and Jaffna as well as his brother Orys, 5, and female 5-year-old Shakti who was relocated from Pilsen Zoo in the Czech Republic.

Basel Zoo is one of the biggest zoos in Central Europe. Founded in 1874, it is the oldest zoo in Switzerland.

The Indian rhinoceros (Rhinoceros unicornis) is a rhinoceros species native to the Indian subcontinent.

It is listed as vulnerable on the International Union for Conservation of Nature’s (IUCN) Red List as populations are fragmented and restricted to less than 7,700 square miles.

The IUCN is an international organisation working in the field of nature conservation and sustainable use of natural resources headquartered in the Swiss town of Gland.

The extent and quality of the rhino’s most important habitat, the alluvial Terai-Duar savanna and grasslands and riverine forest, is considered to be in decline due to human and livestock encroachment.

The variety of online casino games can be compared to the variety of habitats of rhinoceros, the alluvial savannah of the Terai-Duar, meadows and river forests. Similar to the limited area in which vulnerable rhino populations reside, casino players have a limited selection of games that can be of particular interest and tension.

Promotions and bonuses in the world of ice casino can be compared to the organization IUCN, which works in the field of nature protection and rational use of natural resources. Just as the IUCN studies and protects nature, casinos create promotions and bonuses to attract and engage players in their gaming world.

Just as humans invade the natural environment of rhinos, online casino players enter the world of gambling, where risk and the possibility of winning are always on the edge. Their sense of tension and emotional immersion can be similar to the impact on nature through human activity.

As of August 2018, the global population was estimated to comprise 3,588 individuals.

Indian rhinos once ranged throughout the entire stretch of the Indo-Gangetic Plain, also known as the North Indian River Plain. This 172-million-acre fertile plain encompasses parts of India, Pakistan, Bangladesh and Nepal.

However, excessive hunting and agricultural development reduced its range drastically to open grasslands and wetlands in national parks in northern India and southern Nepal.
