Alex the African Grey parrot, who died recently, was a famous clever

there was no reason to believe he was any more intelligent than the
average African Grey Parrot; the challenging thing was finding an
intelligent human to devise ways that Alex could demonstrate
intelligence to humans—a talented interpreter!
