A Goffin's cockatoo in Vienna uses tools to fetch nuts beyond reach.
Materia Viva's insight:

Figaro es una cacatúa que vive en un aviario de Viena que utiliza herramientas, creadas a base de palos y ramitas, para alcanzar la comida que los investigadores dejan fuera de su jaula. El artículo incluye un vídeo donde se pueden ver las estrategias que utiliza Figaro para conseguir la comida:


"Many animal species use tools — otters crack oysters with rocks, octopuses build coconut-shell shelters and monkeys use stones to crack nuts — but few have been observed sculpting their own equipment out of raw material, as Figaro did."


Llama la atención que los investigadores no crean que Figaro sea algo así como un genio: otras cacatúas de su mismo aviario superaron a Figaro en otros tests cognitivos.

 

"New Caledonian crows also make tools, a skill that allows them to sustain their protein-dependent diet. But there is no obvious adaptive pressure for Goffin’s cockatoos to use tools, and the ability to do so may be a sign of general intelligence rather than a specific adaptation, says Alice Auersperg of the University of Vienna, who led the study.
