Watch clever cockatoos make tools from strips or cardboard to reach their food

Watch clever cockatoos make tools from strips or cardboard to reach their food

Cockatoos have once again proved just how intelligent they really are.

A new study shows that captive Goffin's cockatoos are able to make tools and adjust their length in order to get food that's just out of reach.

The skill, however, so far only appears to extend to tool length; During the experiments, only one of the birds was able to cut its tool down to a small enough to open narrower opening.

In a new study PLOS One, six adult cockatoos were assigned to a food reward, which was placed in a box with a small opening.

The birds were given cardboard sheets, and food could be anywhere between 4 and 16 centimeters away in the box.

By and large, the cockatoos were able to adjust the length of their cardboard tools to reach the treat.

To do this, the birds used one of two strategies: shearing or bending.

"They would either be through the entire length of the material (using a tool) using both mandibles and anvil or adjusting the length of the tool. with a lateral slash of the upper mandible, while creating a curve in the cardboard (cut-out tool), "the team wrote.

The researchers also noted that, "the researchers also note.

When their first-attempt tool was too short, their second-attempt tool significantly longer.

This, the team says, may be a risk-avoidance strategy.

The truth is that the cockatoos could indeed adjust their tool-making behavior in the predicted direction, but with some limits in accuracy, "says lead author Alice Auersperg, from the Medical University of Vienna, Austria.

WHY CROWS ARE AS SMART AS CHILDREN

Crows have reasoning ability rivalling that of a human seven-year-old, research has shown.

Scientists came to the conclusion of the problem after subjecting six New Caledonian crowds to a battery of tests designed to challenge their understanding of cause and effect.

The tasks were all variations of the Aesop's fable, in which a thirsty crow drops stones to raise the level of water in a pitcher.

In the 'water displacement task', crows worked out how to catch floating food rewards by dropping heavy objects into water-filled tubes.

They are rather easy to use, rather than floating objects, to choose a high water level tube over one with low water level, and a water-filled tube over one filled with sand.

The birds' understanding of the effects of volume displaced matched that of human children aged between five and seven, scientists from the University of Auckland claimed.

When it came to the tool's width, though, the cockatoos ran into some issues.

Only one bird was able to make a narrow enough tool when the opening was small.

According to the team, this is the result of the technique of using the cardboard in the first place.

In the future, they plan to use less cognitive capabilities, or limitations of the shearing strategy.
