**Palm cockatoos whittle twigs to make drumsticks for tapping on tree limbs**

A pair of biologists at Australian National University, working with one colleague from the University of Queensland and another from James Cook University, has found that male palm cockatoos tap out unique rhythms on tree branches using custom-made drumsticks. In their project, reported in Proceedings of the Royal Society B, R. Heinsohn, C. N. Zdenek, D. Appleby and J. A. Endler studied the wild birds living in Kutini-Payamu National Park, Queensland.
