Behavioural reciprocity can be evolutionarily stable1–3. Initial increase in frequency depends, however, on reciprocal altruists interacting predominantly with other reciprocal altruists either by associating within kin groups or by having sufficient memory to recognize and not aid nonreciprocators. Theory thus suggests that reciprocity should evolve more easily among animals which live in kin groups. Data are available separating reciprocity from nepotism only for unrelated nonhuman animals4… Expand
Does food sharing in vampire bats demonstrate reciprocity?
TLDR
Factors that predict food sharing in vampire bats are reviewed based on previously published and unpublished data, validate previous published results with more precise relatedness estimates, and describe current evidence for and against alternative explanations for its evolutionary stability.

Cooperation and social bonds in common vampire bats
Regurgitated food sharing among vampire bats is a classic textbook example of reciprocity (" reciprocal altruism "). But many authors have contested both the notion that reciprocity explains vampireExpand
Social benefits of non-kin food sharing by female vampire bats
TLDR
Results indicate that a bat can expand its network of possible donors by helping non-kin, suggesting the possibility of alternative responses to a partner's inability to reciprocate. Expand
Correlated pay-offs are key to cooperation
TLDR
It is found that neither the cognitive requirements of reciprocal cooperation nor the often sequential nature of interactions are insuperable stumbling blocks for the evolution of reciprocity. Expand
Correlated payoffs are key to cooperation
The general belief that cooperation and altruism in social groups result primarily from kin selection has recently been challenged, not least because results from cooperatively breeding insects andExpand
Experimental evidence of reciprocal altruism in the pied flycatcher
TLDR
Experimental evidence of mobbing behaviour, the joint assault on a predator in an attempt to drive it away, is presented as reciprocal altruism in the breeding pied flycatcher (Ficedula hypoleuca). Expand
Reciprocal altruism in bats and other mammals
TLDR
It is suggested that reciprocal altruism can be selectively more important than kin selection when altruistic behaviors in a relatively large social group occur frequently and provide a major fitness benefit to the recipient even when that recipient is related to the donor. Expand
Grooming reciprocation among female primates: a meta-analysis
TLDR
A meta-analysis of grooming reciprocation among female primates showed that female primates groom preferentially those group mates that groom them most, and this result holds true when controlling for maternal kinship. Expand
A proximate perspective on reciprocal altruism
TLDR
Three types of reciprocity are distinguished: Symmetry-based reciprocity is cognitively the least complex form, based on symmetries inherent in dyadic relationships, while Attitudinal reciprocity, which is more cognitively complex, is based on the mirroring of social attitudes between partners and is exhibited by both capuchin monkeys and chimpanzees.

Grooming reciprocity in wild male chimpanzees
Understanding cooperation between unrelated individuals remains a central problem in animal behaviour; evolutionary mechanisms are debated, and the importance of reciprocity has been questioned.Expand

TLDR
Here I describe a variety of mutually beneficial interactions between birds that typically are not genetically related, and the three major theoretical conditions for the evolution of cooperation appear to agree well with the empirical data described here. Expand
Are Dolphins Reciprocal Altruists?
TLDR
The literature on dolphins suggests the existence of a system based to a considerable degree on reciprocal altruism, and it is concluded that in dolphins the authors are surely dealing with complicated social systems whose outlines they are now just beginning to understand. Expand

Abstract A general model is presented for the evolution of social behavior by reciprocation. The results of our model apply to social traits which are transmitted from one generation to the next by aExpand

The flow of excess dietary water through the common vampire bat during feeding
TLDR
Between 5.2 and 12.2 min after feeding, the rates of both fluid absorption from the stomach and excretion of urine were about equal, and during this time the blood volume of the bat was increased by about 17% due to the absorbed fluid. Expand
