This is the adorable moment a baby chimp laughed for the first time while getting a tickle from her zookeeper carers.
Little Maisie is only 11 weeks old, and just like a human baby is learning to interact and getting to grip with facial expressions.
The female chimp was born at the Oklahoma City Zoo in late August, but moved to Maryland Zoo to be hand-reared after her birth mum rejected motherhood.
She is due to be paired with a surrogate chimp mum – but for now is being given round the clock care by zoo keepers.
The adorable clip shows Maisie playing with human baby toys and giggling with a wide grin at carers, who give her a tickle under her arms.
It was filmed at The Maryland Zoo in Baltimore on November 3.
The Chimp Forest Animal Care team work in three shifts around the clock to provide her constant care.
Pam Carter, area manager said: “Maisie drinks baby formula every three hours, sleeps, and has some playtime every day to help strengthen her muscles.
“We also wear a shirt and blanket that have fringe material sewn on that helps her learn
to grip.”
Maisie was born weighing approximately 4lb to first-time mother Nia, a 12-year-old chimpanzee, on August 28.
