(STUDY FINDS) -- TENERIFE, Spain — Parrots have long been considered intelligent birds, but a new set of research focusing on African gray parrots finds that besides just being smart these fascinating animals are also very kind to one another.
Over the course of the experiments, the studied parrots exhibited selfless tendencies, prosocial behavior, and cooperativeness — even when there were no obvious opportunities for reciprocation. Furthermore, these extraordinary birds returned favors or good deeds amongst one another, and never became jealous whenever a particular bird received a larger reward than others. These traits are exceedingly rare in the animal kingdom, with only great apes behaving in similarly selfless ways.

All in all, these findings make a strong case that parrots are among the smartest animals on the planet, rivaling crows, apes, and dolphins in terms of overall and social intelligence.
