Harley the cockatoo likes to take things in her stride. Whether it’s knocking over cups or playing bowling on his custom scooter, she’s not a bird whose feathers are easily ruffled. When faced with a new cockatoo, in the form of a “mirror sister,” Harley is unsure what to do. First, she kisses the new arrival, before turning her back and then turning around quickly to catch out the other bird. Credit: YouTube/Harley the cockatoo
