Four bears have celebrated their birthdays with a cake and presents.
The two sets of twins, named Gemini, Albie, Nilas and Neo, turned two and three within a week of each other.
They received presents and a cake made by Great British Bake Off star Briony Williams to mark the occasion.
Will Walker, animal manager, said: “The bears were quite shy when they first arrived, but have become very confident and have formed lovely, trusting relationships with their keepers.
“The four bears all get along very well and love exploring their huge, woodland paddock – climbing the trees, foraging, and swimming in their pool.
“We have four very drowsy bears but I’m sure they have enjoyed some extra treats for their birthdays today.”
The bears are not yet fully grown and could reach up to 350kg for males and 200kg for females.
