Goffin's Cockatoos and Tool Use

Researchers at the University of Veterinary Medicine Vienna discovered that Goffin's cockatoos can use and transport tools to obtain food. They designed a puzzle box experiment where cockatoos used a short stick and a long probe to retrieve a cashew. The birds demonstrated problem-solving skills by breaking paper membranes and using the probe to fish out the nut. Some cockatoos even carried both tools simultaneously to overcome obstacles, a behavior previously observed only in humans and chimpanzees.

What unique ability of Goffin's cockatoos was discovered by researchers?

• They can solve mathematical problems.

• They can use and transport tools.

• They can mimic human speech.

• They can fly long distances.

What was the purpose of the puzzle box in the experiment?

• To test the cockatoos' flying skills.

• To observe cockatoos' social interactions.

• To see if cockatoos can mimic sounds.

• To challenge the cockatoos to retrieve a treat.

Which two tools were provided to the cockatoos in the experiment?

• A rope and a pulley.

• A hammer and a nail.

• A net and a hook.

• A short stick and a long probe.

What was the ultimate goal for the cockatoos in the experiment?

• To build a nest.

• To retrieve a cashew.

• To learn a new song.

• To fly through a hoop.

What additional challenges were introduced in the experiments?

• Larger puzzle boxes.

• Different types of food.

• Obstacles like a gap to fly over or a ladder to climb.

• New types of tools.

Which other species have shown similar tool-using behavior as cockatoos?

• Dogs and cats.

• Dolphins and whales.

• Elephants and lions.

• Humans and chimpanzees.
