Tiger cub is not yet visible to the public.

Rome's Bioparco zoo has announced the birth of a female Sumatran tiger, a critically endangered species native to the tropical forests of the Indonesian island.

The tiger cub, born to mother Tila and father Kasih, is described by the Bioparco as being in good health and "very lively" but is not visible to the public yet.

The Bioparco says the birth of the animal is of great significance as it is estimated that there are fewer than 600 Sumatran tigers left living in the wild.

Per adesso il suo ruggito non è granché. Ma protetta dalle cure di mamma Tila e dei keeper del #BioparcoDiRoma, la cucciola di #Tigre di Sumatra cresce a vista d'occhio. Appartiene a una specie a rischio di estinzione: in tutto il mondo ne sono rimaste meno di 600 in natura. pic.twitter.com/eOrgd6agZ4

The cub's mother Tila was born in 2011 at Chester Zoo in England and came to Rome from Heidelberg Zoo in Germany, while the father Kasih was born in 2014 at Beauval Zoo in France.

The Sumatran tiger, a tiger subspecies, is at risk of extinction due to poaching, habitat loss and human-wildlife conflict.
