“…In allopreening, interactions are often two-way, with continual reversal of the roles of altruist and recipient, but in some species allopreening is just one-way (Harrison 1965). If we are to explain two-way allopreening as reciprocal altruism then, unless the reciprocation is in a di¡erent currency, we must look for a di¡erent class of explanation for one-way allopreening.…”

“…It is not clear how reciprocity could explain altruism which is consistently asymmetric or even entirely one-way. Yet allopreening, for example, is two-way in some species of birds but just one-way in others (Harrison 1965). Humans often seem to be more altruistic than would be predicted on economic grounds (see, for example, Frank 1988).…”

Current work on cooperation is focused on the theory of reciprocal altruism. However, reciprocity is just one way of getting a return on an investment in altruism and is di¤cult to apply to many examples. Reciprocity theory addresses how animals respond dynamically to others so as to cooperate without being exploited. I discuss how introducing di¡erences in individual generosity together with partner choice into models of reciprocity can lead to an escalation in altruistic behaviour. Individuals may compete for the most altruistic partners and non-altruists may become ostracized. I refer to this phenomenon as competitive altruism and propose that it can represent a move away from the dynamic responsiveness of reciprocity. Altruism may be rewarded in kind, but rewards may be indirectly accrued or may not involve the return of altruism at all, for example if altruists tend to be chosen as mates. This variety makes the idea of competitive altruism relevant to behaviours which cannot be explained by reciprocity. I consider whether altruism might act as a signal of quality, as proposed by the handicap principle. I suggest that altruistic acts could make particularly e¡ective signals because of the inherent bene¢ts to receivers. I consider how reciprocity and competitive altruism are related and how they may be distinguished.

“…Allopreening helps reduce ectoparasites on the head and neck, which are impossible to self-preen. Allopreening is a widespread behavior observed in many species of birds [129]. It is most common between courting and mated individuals, and between parents and their offspring.…”

“…It is most common between courting and mated individuals, and between parents and their offspring. Harrison [129] argued that allopreening serves mainly a social function, such as reinforcement of the pair bond, and is of little or no importance for ectoparasite control. However, subsequent studies indicate a role for allopreening in parasite control [130][131][132][133].…”

Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to featherdegrading bacteria. Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional significance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence -or lack thereof -for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well as anti-parasite behaviors. In some cases, we present original data from our own recent work. We make recommendations for future studies that could improve our understanding of this poorly known aspect of avian biology.

“…Allopreening (Harrison 1965) is another facet of prion behaviour associated with aggressiveness. Mutual preening is common, particularly when territorially is at a maximum in late November and early December.…”
