WASHINGTON Nike Air VaporMax CS Suisse , July 15 (Xinhua) -- It is well known that ravens aresmart, but a new study showed the birds may be more intelligentthan we previously thought.


Experiments conducted by Swedish researchers found that ravenscan plan ahead for different types of events, and they are willingto forgo an immediate reward for a better one in the future.


This type of planning has historically been thought to be uniqueto humans and great apes, according to the study published thisweek in the U.S. journal Science.


Previously, ravens and other members of the corvid family areknown to cache food to eat at a future date.


However, some scientists considered this behavior different fromthe planning exhibited by apes and said that it might just reflecta specific adaptation confined to the food hoarding domain.


Now Nike Air VaporMax 97 Suisse , researchers at Sweden's Lund University let ravens solvetasks that they don't encounter in the wild: using tools andbartering with humans.


First, ravens were trained to drop a simple tool, a stone, intoa puzzle box through an opaque tube, causing the box to release areward from an opening in the bottom.


Then, the box and the stone were removed. One hour later Nike Air VaporMax 95 Suisse , theravens were given the stone, as well as several "distractors" suchas a wooden wheel, a wooden ball, a metal pipe and a toy car.Fifteen minutes later, the birds got the box back.


It turned out nearly every raven chose the stone, and upon beingpresented with the box Nike Air VaporMax 2019 Suisse , they used the tool to open it, with asuccess rate of 86 percent.


The researchers repeated the same experiment with a 17-hourdelay in returning the box to the ravens, and the success rate was88.8 percent.


A high success rate was also seen in similar experiments whereravens used a token to later barter for a reward.


The researchers found the birds selected the tool or token about73 percent of the time.


Even when the ravens knew that trading would only happen on thenext day, they chose and stored these tokens as soon as they wereoffered to them.


"To be able to solve tasks like these, one needs a collection ofcognitive abilities working in concert, such as inhibitory skillsand different forms of memory Nike Air VaporMax 2018 Suisse ," study author Mathias Osvath,associate professor in cognitive zoology at Lund University, saidin a statement.


"That ravens show similar functions, and combine them in wayssimilar to apes, despite a last common ancestor as far back as 320million years ago, suggests that evolution likes to re-run goodproductions Nike Air VaporMax 2.0 Suisse ," Osvath concluded. Enditem
