Parrots are known for learning and speaking human languages; it's what makes these beautiful birds so fascinating.
Also, dangerous (depending on who you are rooting for).
According to a report from NBC, a parrot in Brazil warned his masters of a police car approaching their house for a drug raid by saying 'mama, police' in Portuguese. The parrot was arrested later on.
What seems like a possible plot for a Bollywood comedy, is actually a real story. However, in an anticlimax for the masters, they were still busted and large amounts of money and drugs were seized from their house.
