“…We aim to further this work by focusing on a group that has garnered attention for its unusual parental care behaviour. The penduline tits exhibit diverse parental strategies, with the Eurasian Penduline Tit Remiz pendulinus exhibiting unusual sex-specific patterns of care which are consistent across populations and repeatable within individuals (Persson & Ohrstrom 1989, Pog any et al 2008, van Dijk et al 2010a.…”

In most passerine birds, individuals attempt to maximize their fitness by providing parental care while also mating outside their pair bond. A sex-specific trade-off between these two behaviours is predicted to occur, as the fitness benefits of extra-pair mating differ between the sexes. We use nest observations and parentage analysis to reveal a negative association between male care and the incidence of extra-pair paternity across three species of penduline tit (Remizidae). This provides evidence of a trade-off between these two behaviours, possibly due to the devaluing of paternal care by extra-pair offspring.

“…One potential example is the curious breeding system of the penduline tits (Remiz pendulinus) [30]. In this species, males build (with some help by the female) an elaborate nest, and either the male or the female, but not both, cares for the brood while the other deserts.…”

The evolution of payoff matrices: providing incentives to cooperate

Most of the work in evolutionary game theory starts with a model of a social situation that gives rise to a particular payoff matrix and analyses how behaviour evolves through natural selection. Here, we invert this approach and ask, given a model of how individuals behave, how the payoff matrix will evolve through natural selection. In particular, we ask whether a prisoner's dilemma game is stable against invasions by mutant genotypes that alter the payoffs. To answer this question, we develop a two-tiered framework with goal-oriented dynamics at the behavioural time scale and a diploid population genetic model at the evolutionary time scale. Our results are two-fold: first, we show that the prisoner's dilemma is subject to invasions by mutants that provide incentives for cooperation to their partners, and that the resulting game is a coordination game similar to the hawk-dove game. Second, we find that for a large class of mutants and symmetric games, a stable genetic polymorphism will exist in the locus determining the payoff matrix, resulting in a complex pattern of behavioural diversity in the population. Our results highlight the importance of considering the evolution of payoff matrices to understand the evolution of animal social systems.Keywords: evolutionary game theory; prisoner's dilemma; hawk -dove game; behavioural dynamics; two-tiered model INTRODUCTIONEvolutionary game theory (EGT) is one of the fundamental tools to study how behaviour and traits of organisms evolve by natural selection. An evolutionary game is defined by different genetical strategies and their fitness (i.e. reproductive output) when they interact with each other. The genotypes increase or decrease in frequency according to their fitness given the frequencies of other strategies in the population. This process frequently (but not always) leads to an evolutionarily stable strategy (ESS), which is a strategy that, when fixed in the population, cannot be invaded by alternative strategies. Earlier EGT models in biology tended to assume that the genetical strategies correspond to actual behaviours [1], or simple conditional rules that prescribe a certain behaviour given the state of the individual and the interaction (e.g. the tit-for-tat strategy [2]). More recent work has focused on interactions where individuals' behaviour is not directly determined by their genes, but instead reflect the outcome of a dynamical process where the players respond to each other according to proximate mechanisms that prescribe their behaviour [3][4][5][6][7]. In particular, Roughgarden [8] calls for an explicitly two-tiered conception of behavioural evolution: the first tier describes the dynamics of behaviour within the time scale of an interaction where individuals can adjust their actions in response to the context and the behaviours of others. The second tier, on the other

“…Thus, dispersal within and between populations may alter the local ratios of sexually receptive males and females and thereby influence mating systems Pilastro et al, 2001). For example, local mating opportunities were suggested to influence clutch desertion and mating system in European penduline tit Remiz pendulinus (Persson and Öhrström, 1989).…”

“…Males desert 50-70% of clutches, whereas females desert 5-20% of clutches. In addition, 30-40% of clutches are deserted by both parents, so that these offspring are doomed to failure (Franz and Theiss, 1983;Persson and Öhrström, 1989). Both sexes may have up to 5-7 mates within a single breeding season at different locations (Cramp and Simmons, 1983).…”

Breeding site fidelity in penduline tit Remiz pendulinus in Southern Hungary

et al. 2005

Birds move between breeding locations to gain a better territory, avoid competition or reduce the deleterious effect of inbreeding. We investigated breeding site fidelity in a small European passerine, the penduline tit (Remiz pendulinus). This species has an exceptionally diverse breeding system, in which both males and females may have up to 5-7 mates in a single breeding season, and the eggs are incubated by a single parent: either the male or the female. We investigated the movements of males and females within three breeding seasons in Southern Hungary (2002)(2003)(2004). Males moved for shorter distances between breeding sites (116 m, 63-333 m; median, lower quartile-upper quartile) than females (942 m, 415-2,382 m). Movements of males and females were consistent between years, and they were repeatable between subsequent nests of males, but not of females. Taken together, our results suggest that adult male penduline tits are more site-faithful than adult females. We suggest that this difference has an implication on their breeding ecology since male parental behaviour (desert/care) is expected to be influenced by local mating opportunities, whilst female parental behaviour is likely to depend on the mating opportunities in a large area around their breeding site.
