This is an article about the Black Palm Cockatoo and one of their courtship behaviors but what is super interesting about it is not that they drum (lots of birds do!) but that they are the ONLY animals that use a tool to do it AND that individual birds have each their own 'music' which they repeat in the same pattern -something which makes scientists believe that it's done on purpose so other males can recognize the bird doing it - is that UNBELIEABLE OR WHAT?!! When I tell you that there is no class of animals more amazing than birds, I am not exaggerating!!!
