Video showing the talking bird impresses Internet users
A new video uploaded to social media shows a talking raven who lives in Ukraine's Kharkiv Zoo. The bird's name is Karl.
According to the zoo director, the raven has been living here for 20-30 years. He can imitatate human speech.
"The raven was brought to the zoo a long time ago. He repeats whatever words he hears. Nobody specifically taught him how to talk", says zoo director Oleksiy Hryhoryiev.
The raven's vocabulary is small comprising just a few words, including his name Karl and a phrase 'come on' ('davai, davai' in Russian). Yet he reproduces them with an amazing accuracy.
Scientists say, ravens are as intelligent as chimpanzees. They show a high level of self-control and are able to behave rationally.
