(Phys.org) -- Researchers at the University of Vienna have discovered that carrion crows are able to distinguish between familiar and unknown human voices. They also found, as they write in their paper published in the journal Animal Cognition, that the birds are able to do the same with other birds outside of their species, though they react in different ways.
