While at the Town Centre Arcade in the Katoomba Blue Mountains of New South Wales, Australia, a visitor captured wonderful footage of a very determined cockatoo who kept busy by removing strips of anti-bird spikes from a building’s exterior to clear the way for a perfect perch. As the resolute bird methodically detached the strips one by one from their hold, they fell onto the ground with a satisfying clank.
