Parrots can be taught to imitate a number of phrases, expressions and sounds. In this video, a bird named Homer laughs just like a human.
He starts off by repeating common phrases such as “ola”. Then the green parrot displays how far he’s developed his skills by spurting out human-like laughs, along with a crowd of people. While the video is very light and happy, the thought of hearing a high-pitched laugh in the middle of the night is unsettling.
