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… 

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 vampire

Does food sharing in vampire bats demonstrate reciprocity?

Factors that predict food sharing in vampire bats are reviewed based on previously published and unpublished data, validate previous published results with more precise relatedness estimates, and describe current evidence for and against alternative explanations for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.

Correlated pay-offs are key to cooperation

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.

Social benefits of non-kin food sharing by female vampire bats

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.

Correlated payoffs are key to cooperation

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.

Experimental evidence of reciprocal altruism in the pied flycatcher

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).

Grooming reciprocation among female primates: a meta-analysis

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.

A proximate perspective on reciprocal altruism

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.



Cooperation and Reciprocity in Avian Social Systems

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.

Reciprocal altruism in Papio anubis

It is reported here that altruistic behaviour involving the formation of coalitions among male olive baboons (Papio anubis) fulfils the criteria for reciprocal altruism.

The evolution of cooperation.

A model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game to show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.

The Predatory Behavior of Wild Chimpanzees

This report on predatory behavior in chimpanzees in the Gombe National Park of Tanzania is based in part upon a decade of observations by a research team living in the park, but primarily upon numerous episodes he observed since early 1968.

Energetics and the Distribution of Vampires

The limits in distribution of Desmodus are correlated with the 10°C minimal winter isotherm both in Mexico and in Argentina and Chile, and more than 90 per cent of which is committed directly to homeostasis and to the cost of handling the food.

Observational study of behavior: sampling methods.

Seven major types of sampling for observational studies of social behavior have been found in the literature and the major strengths and weaknesses of each method are pointed out.
