"It's an event because it's the first black rhino to be born in a French zoo," the Bassin d'Arcachon Zoo said in a statement.

The species -- formally called the Diceros bicornis -- is classified as "critically endangered" by the International Union for the Conservation of Nature (IUCN).

The young calf was born weighing between 35 and 40 kilogrammes (around 80 pounds).

As it is a male, it will be expected to breed to preserve the species as the majority of black rhinos in zoos are female, the park said.

According to the zoo, the unnamed new born is the second black rhino to be born in Europe this year.
