Palm cockatoos use tools to make music
Cockatoos are already known for their wicked dance moves, but
study reveals that they can create their own beat as well. Researchers
observing 18 palm cockatoos (Probosciger aterrimus) in northern
Australia discovered that, when courting a mate, male cockatoos grab a stick or
a seedpod and start rhythmically whacking a hollow tree branch, producing a
steady beat. One can see the video of same in youtube at https://youtu.be/lKHmfkh7nJk while the
