Two adorable spotted hyena cubs have been born at Yorkshire Wildlife Park – and visitors were the first to spot them.

Delighted rangers were relieved to see a 'supermum' hyena bring her cubs in from the cold, when torrential rains threatened to flood her underground den where she was keeping her newborns safe.

Doncaster’s Yorkshire Wildlife Park has welcomed two new spotted hyena cubs to first time mum Noubia.

The cause of death of Kiko, a 13-year-old male giraffe that died at the Toronto Zoo on New Year’s Day, has now been released.

From an evolutionary standpoint, it’s ruthlessly efficient. The queen collects sperm from multiple drones in one flight, stores it for years, and then spends her life laying up to 2,000 eggs a day.
