Abstract
Innovative tool manufacture is rare and hard to isolate in animals. We show that an Indonesian generalist parrot, the Goffin's cockatoo, can flexibly and spontaneously transfer the manufacture of stick-type tools across three different materials. Each material required different manipulation patterns, including substrates that required active sculpting for achieving a functional, elongated shape.
Highlights
Animal tool use is a target of concerted research effort owing to its potential for revealing cognitive capabilities
We show that an Indonesian generalist parrot, the Goffin’s cockatoo, can flexibly and spontaneously transfer the manufacture of stick-type tools across three different materials
Our results show that Goffin’s cockatoos can make functional tools with similar shape from different materials, using distinctive manipulation patterns on the different substrates
