Researchers were trying to address the deficiency in studies of raven intelligence that focused only on whether the bird knew that the researcher was hiding something: A new study that that tries to address that deficit provides some of the best proof yet that ravens, including young birds of just four months of age, have certain types of smarts that are on par with those of adult great apes.
