<p>Harley the cockatoo likes to take things in her stride. Whether it’s <a class="link" rel="nofollow" target="_blank" href="http://newswire.storyful.com/storylines/*/stories/116202">knocking over cups</a> or <a class="link" rel="nofollow" target="_blank" href="http://newswire.storyful.com/storylines/*/stories/110474">playing bowling on his custom scooter</a>, 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</p>
