Baby birds can do arithmetic, say researchers in Italy. Scientists from the universities of Padova and Trento demonstrated chicks' ability to add and subtract objects as they were moved behind two screens.
It is already known that many non-human primates and monkeys can count, and even domestic dogs have been found to be capable of simple additions. But this is the first time the ability has been seen in such young animals, and with no prior training.
