In this clip we see a Hill Myna (Gracula religiosa) speaking Japanese during an exchange with its owner. Hill Mynas are renowned for the mimicry and some have placed their ability near or on par with African Grey Parrots. They can learn to reproduce many everyday sounds, whistled tunes and particularly the human voice, with remarkable accuracy and clarity.

According to comments on reddit, the conversation roughly translates as follows:

Bird:” ‘Uhm Hello, this is the Ono family.”
Bird: “What’s wrong?”
Owner: “Abe-chan, you’re a little too early. Once the phone’s picked up, then properly say hello.”
Bird: “Okay, understood.”
Owner: “Do you really understand? I’m counting on you. Hello, this is the Ono family residence in Gifu.”
Bird: “Okay, I understand!”
Owner: “Got it.”
