Sexy tools: Individual differences in drumming tool shape

Heinsohn et al. Proceedings of the Royal Society B, 290, 2023.1271, (2023) report that the choice of tool type (drumsticks or seed pods) and the shape of drumsticks manufactured by palm cockatoos differ among individuals. This variation does not seem to be culturally transmitted as no spatial correlation between proximity of display trees and tool shape was found.
