One of the main characteristics of human societies is the extensive degree of cooperation among individuals. Cooperation is an elaborate phenomenon, also found in non-human primates during laboratory studies and field observations of animal hunting behaviour, among other things. Some authors suggest that the pressures assumed to have favoured the emergence of social intelligence in primates are similar to those that may have permitted the emergence of complex cognitive abilities in some bird… 
A study of sharing and reciprocity in grey parrots (Psittacus erithacus)
In both experiments, birds could learn to cooperatively reward a partner at little cost to themselves—by sharing—and potentially maximize overall reward by reciprocating such sharing.
Blue‐throated macaws ( Ara glaucogularis ) succeed in a cooperative task without coordinating their actions
Social complexity may select for socio‐cognitive abilities. The “loose string” task has become a comparative benchmark paradigm for investigating cooperative problem‐solving abilities in many
Problem-solving in a cooperative task in peach-fronted conures (Eupsittula aurea)
The findings show that peach-fronted conures can solve a cooperative task, and that cooperation success is not determined by external cues or by partner identity or affinity.
Cooperative problem solving in giant otters (Pteronura brasiliensis) and Asian small-clawed otters (Aonyx cinerea)
Two species of otters show some ability to cooperate, quite similar to most other species presented with the same task, however, to draw further conclusions and more nuanced comparisons between the two otter species, further studies with varied methodologies will be necessary.
Dogs (Canis familiaris) and wolves (Canis lupus) coordinate with conspecifics in a social dilemma.
The results of this study show that wolves do not always outperform dogs when coordinating their actions, but that the cooperative behavior of Canis depends on many factors, including rank, type of task, and tolerance within the dyad.
Assessing African grey parrots' prosocial tendencies in a token choice paradigm
African grey parrots show the potential for prosociality and reciprocity; however, considering their lack of understanding of the contingencies of the particular tasks used in this study, the underlying motivation for the observed behaviour remains to be addressed by future studies, in order to elucidate the phylogenetic distribution of prossociality further.
Importance of a species’ socioecology: Wolves outperform dogs in a conspecific cooperation task
Results call those domestication hypotheses that suggest dogs evolved greater cooperative inclinations into question into question, and support the idea that dogs’ and wolves’ different social ecologies played a role in affecting their capacity for conspecific cooperation and communication.
Keas Perform Similarly to Chimpanzees and Elephants when Solving Collaborative Tasks
The kea, a parrot endemic to New Zealand, is presented with a series of tasks designed to assess cooperative cognition, and it is found that keas were capable of working together, even when they had to wait for their partner for up to 65 seconds, the first demonstration that any non-human animal can wait for over a minute for a cooperative partner.
Speaking of psittacine research
Research with other grey parrots has led to further appreciation of their cognitive and communicative facilities, and at least one grey parrot, named ‘Griffin,’ seems to understand the notion of reciprocity.


Cooperative problem solving in rooks (Corvus frugilegus)
Results may indicate that cooperation in chimpanzees is underpinned by more complex cognitive processes than that in rooks, which may arise from the fact that while both chimpanzees and rooks form cooperative alliances, chimpanzees, but not rooking, live in a variable social network made up of competitive and cooperative relationships.
Cooperative problem solving in a social carnivore
How do African grey parrots (Psittacus erithacus) perform on a delay of gratification task?
This task demanded not just a choice of delayed reward but the maintenance of delayed gratification and was clearly difficult for the parrots to learn; additional training or alternative paradigms are required to better understand the capacity for self-control in this and other species.
The discrimination of discrete and continuous amounts in African grey parrots (Psittacus erithacus)
Results with both individual items and volume discrimination suggest that parrots use an analogue of magnitude, rather than object-file mechanisms to quantify items and substances.
Tolerance Allows Bonobos to Outperform Chimpanzees on a Cooperative Task
Social factors determine cooperation in marmosets
Abstract We investigated which factors determine cooperative behaviour of common marmosets, Callithrix jacchus , in an instrumental task. During the approach phase each of eight individuals of a
Cognitive adaptations of social bonding in birds
It is argued that cognition may play an important role in the maintenance of long-term relationships, something the authors name as ‘relationship intelligence’.
Use of experimenter-given cues by African gray parrots (Psittacus erithacus)
The ability of three African gray parrots to use different human cues (pointing and/or gazing) in an object-choice task is tested and sensitivity to joint attention as a prerequisite to understand pointing gestures as it is to the referential use of labels is discussed.
The evolution of the social brain: anthropoid primates contrast with other vertebrates
It is suggested that, among vertebrates in general, pairbonding represents a qualitative shift from loose aggregations of individuals to complex negotiated relationships, and that these bonded relationships have been generalized to all social partners in only a few taxa (such as anthropoid primates).
