Crow can recognize human voices

Scientists used recordings of human voices and screams to test the reaction of eight crow in the birdhouse of the University of Vienna.

They recorded the voices of 5 people who fed crows every day and 5 others 'never seen them'.

When the recordings are open to the raven, they react more to the unfamiliar voices, look up and turn to the sound.

"Because humans can be a serious threat to crows, so if they hear strangers talking, they have to be alert ," Ms. Wascher said.

According to her, although crows are a very intelligent animal, most of the previous studies focused on their ability to recognize and communicate with their fellow humans.
