What is it about?
In this paper, I report on the evolution of tool use by the Egyptian vulture to break Ostrich eggs and how this behaviour could have evolved from simpler but plastic patterns. In this work, the characteristics of the key stimulus are disentangled, and the ethogram is described, supporting the evolutionary theory that points to displacement behaviour as the origin of tool use.

Why is it important?
This is significant because advances in research on this behaviour have been scarce despite the interest in tool use.
Perspectives
With this paper, I have tried to open up the debate on the understanding of this exciting behaviour.
