Two years after his first appearance in his school's talent show, Samuel Henderson returned to the stage for one last performance before leaving high school. The young American, who became famous on social media thanks to his incredible talent, once again impressed his classmates by perfectly reproducing the calls of numerous birds.

Diagnosed with autism and Tourette syndrome, Samuel had a passion for birds from the age of four. During a visit to the Oklahoma City Zoo he began imitating the call of a long-tailed grackle perched on a trash can. Since, he has never stopped learning and perfecting his technique.

Today, Samuel is able to imitate more than a hundred species of birds. His mother explains that he started learning his first calls around the age of 6, before gradually expanding his repertoire through observation and listening to recordings.
