Chimpanzees who attacked drone with a STICK took ‘unique and deliberate action’ say researchers
It is not just humans who are concerned about the privacy implications of drones.
An Arnhem TV station has lost one of its expensive drones after a chimpanzee managed to knock it out of the sky with a stick as it was supposed to be capturing footage of the Royal Burgers Zoo chimp enclosure for a TV show.
The April incident has now been analysed by researchers, who claim it was a ‘unique and deliberate action’.
In an article in the journal Primates published by Springer, Jan van Hooff and Bas Lukkenaar explain it as yet
another example of chimpanzees’ make-do attitude to using whatever is on hand as tools.
‘The use of the stick as a weapon in this context was a unique action,’ comments van Hooff.
‘It seemed deliberate, given the decision to collect it and carry it to a place where the drone might be attacked.’
The incident happened earlier this year, on 10 April, when a Dutch television crew was filming at the zoo in Arnhem.

According to van Hooff and Lukkenaar, the chimpanzees housed at the Royal Burgers Zoo have never explicitly been taught how to use different tools, but have had ample chance to watch humans handle all kinds of implements.
Previous studies showed that the chimps at this Dutch zoo spontaneously and innovatively use up to 13 types of tools in a variety of ways, especially utilizing sticks of different sizes.
The apes appear to choose the size, shape and weight of the tools with a particular use in mind.
Sticks are, for instance, used to gather fresh leaves from overhead branches, while heavy pieces of wood and stones are chosen as throwing weapons.
‘On the morning of Friday, April 10, 2015, the chimpanzees of Royal Burgers’ Zoo once again proved how intelligent they are,’ a spokesman for the zoo said.
The incident happened during filming for a reality show set in the zoo.
Programme makers had hoped to use the drone to capture the enclosure from above.
The zoo did not confirm if it was able to salvage the drone.
