With a little help from my (Psittacidae) friends.

Understanding the distribution of and mechanisms underlying prosocial behavior in other species has been hampered by methodological differences among studies, questions about animals' interpretations of the designs, and low phylogenetic diversity. Brucks and von Bayern's recent report that African gray parrots are proactively prosocial reiterates the importance of social tolerance and suggests a role for perspective taking, but additional work using identical procedures across taxa is needed to verify the cognitive mechanisms underpinning prosocial behavior.
