Grizzly Bear 'Super Mom' Gives Birth To Her 17th Cub Despite Her Old Age

24-year-old Bear 399 from Grand Teton National Park, Wyoming has produced a new litter despite her age. She gave birth to four cubs. which in itself is extremely rare as bears on average only have two or three. 399 has become one of most famous grizzly parents in history and even has her own social media accounts.

Kate and Adam Rice took these amazing photographs of the bear mum walking with her new brood. Adam said: 'We weren't sure if she would have cubs again in her advanced age, let alone four, which is extremely rare. 'We were shocked when we heard the news that she had four cubs, it seemed like her way of proving us wrong. Kate said she and Adam, who works as a photographer at the park, had fallen in love with bears together. She said despite 399's love of places near people she was still very much a wild bear and shouldn't be approached, especially with her cubs.
