The Chester, England, Zoo is celebrating the birth of a rare sun bear, the first of its kind born in the United Kingdom.

The zoo announced the bear’s birth on June 29, sharing footage of the newborn with its mother. The cub’s parents, mom Milli and dad Toni, were rescued from Cambodia after they were taken from their mothers as cubs. They were brought to Chester Zoo in 2015. According to the zoo, the cub was only 400 grams at birth. Credit: Chester Zoo via Storyful
