Beo, mamiang, or golden tiong (Gracula) is a type of bird member of the Sturnidae tribe (starlings and kin). The natural dispersal ranges from Sri Lanka, India, the Himalayas, eastward to the Philippines, Java to the small Sunda archipelago. These birds can be found in the lowlands up to the plateau of more than 2000m. Because of its ability to mimic human language, this bird becomes a popular pet.
An African parrot once witnessed a murder case in the United States. The bird imitated the voice of the victim, a husband named Martin Duram, at the last moment of his life, before his own wife, Glenna Duram, was shot to death.
"Shut up," the bird said in a video. "Do not shoot."
Although it can not be a burdensome witness or a key witness, because it could be a bird imitating from television or other sources, the parrot behavior that can mimic the human voice is interesting. Why can this bird imitate, not just words and sounds, but also imitate exactly the voice of a person?
Through some adaptations, parrots can indeed perform these vocal performances. The secret is in the actual sound system of this bird.
