Experts announced the first famous case of using kea Personal tools for caring for themselves.
They talked about the parrot, which, being disabled, taught to compensate for the imperfections of his body with the help of pebbles-he cleans their plumage.
A family from New Zealand found Bruce in the wild in 2013 with a serious injury-the parrot has no upper part of the beak, which is why he cannot fully take care of himself with this part of the body.
Nevertheless, the bird has incredibly well adapted to life with this disability. To take care of himself, he uses various tools, such as pebbles, clamping them between the lower part of the beak and the tongue.
Scientists watched the parrot for nine days, discovering more and more evidence that his actions were intentional.
«In more than 90% of cases, this creature took a pebble, and then used it to dress; In 95% of cases when the parrot dropped a pebble, he cleaned the pebble or replaced it to resume the improvement», the study says.
According to the authors of the work, the bird chose stones of a certain size for cleaning, and not arbitrary samples from its environment. No other Kea in his environment used pebbles to care for himself.
The use of personal tools in response to shortcomings demonstrates the greater flexibility of their thinking. They easily adapt to new problems.
