Abstract

The results of the long-term studies of parrots’ thinking ability, conducted by the American psychologist I.Pepperberg, are discussed. She showed that these birds are comparable to great apes in their cognitive abilities. It is emphasized that the data of I.Pepperberg coincide with the results, obtained by the authors of this article in the study of corvids. A unique experiment on language learning of African parrot Jaco Alex is described. This bird learned not only the names of objects and actions, but also a number of concepts (more/less, similarity/difference). The ability of Alex to expand the lexicon by imitating people is demonstrated. The ability of the parrot to evaluate and to “name” the emotional state of others (anxiety, irritation, and fatigue) is noted.
