“…Even though our study is not directly comparable with that of Samplonius and Both (2017), both report differences between sexes in social information use for breeding site selection, and our results also suggest a differential effect of individual experience as reflected by age and dispersal status between sexes. Such between-sex differences may result from sex-specific information gathering processes (Reed et al, 1999;Doligez et al, 2004b), in relation to sex-specific fitness benefits associated with breeding system and dispersal processes (Greenwood, 1980). In birds, males are expected to benefit from fine-scale knowledge of their environment, which can be achieved by philopatry and finescale prospecting within the natal habitat and allows them to select and defend high-quality territories where to attract females (Greenwood, 1980;Doligez et al, 2004b).…”

“…Using a quantitative genetic approach , we simultaneously explored the relative contribution of female and male (i) overall experience (age, familiarity with the environment, previous experience with the experimental design, and previous breeding success) and (ii) direct and indirect additive genetic effects on the joint decision to use the manipulated information source for nest site choice. Individuals with low personal information are expected to rely more on social information for decision-making, provided that such information is available to them, compared to individuals with high personal information (Reed et al, 1999;Danchin et al, 2001;Valone, 2007;Doligez and Boulinier, 2008). Therefore, pairs with young and/or naive individuals are expected to show higher propensity to use our manipulated social information than pairs with older individuals and/or individuals more familiar with the environment or with the experimental design, because our experimental social information was provided for all individuals at the time of settlement.…”

Heterospecific Nest Site Copying Behavior in a Wild Bird: Assessing the Influence of Genetics and Past Experience on a Joint Breeding Phenotype

Breeding site selection is often a joint decision of pair members in species with biparental care and the experience of both pair members may influence the use of information for site selection. Nevertheless, quantitative genetics of joint information use for site selection remains unexplored so far. We used an experimental approach to quantify the relative importance of genetics (heritability) and past experience (age, familiarity with the environment, previous breeding success, previous information use) in heterospecific social information use for nest site selection in wild collared flycatchers (Ficedula albicollis). Flycatchers collect social information from resident tits for nest site selection. We created an apparent preference of tits for a novel nest site feature and recorded choices of flycatchers (copying or rejecting the tit preference). Copying behavior was stronger for naive individuals but also differed between years, which could be explained by contrasting seasonality in the demonstrator species. Past experience as reflected by age affected subsequent use of social information: pairs with a yearling male were more likely to copy the heterospecific preference than pairs with older immigrant males. There was no general pattern in successive individual choices over the years. Accordingly, individual repeatability in copying tit preference was very low. At the pair level, we estimated sex-specific direct and indirect genetic effects on the joint nest site decision and found no sex-specific heritability and no cross-sex genetic correlation. Our results confirm the importance of past experience for social information use and suggest that social information use is highly plastic and most likely not genetically inherited in collared flycatchers. Whether individuals use social information should be related to environmentally-induced changes in the quality of information and thus be context-dependent. Selection may therefore act on the ability to optimally use social information in varying environments and on the processes underlying such adjustment, such as learning, rather than the use of information itself.

“…In reality, many organisms do not make such blind dispersal decisions; instead, they may often invest considerable time and/or energy in prospecting potential breeding habitats before deciding on where to settle [5,6]. While there has recently been a surge of interest in the importance of information acquisition and use within ecology [7], these ideas have yet to be properly integrated into our understanding of dispersal evolution.…”

Prospecting and dispersal: their eco-evolutionary dynamics and implications for population patterns

et al. 2014

Dispersal is not a blind process, and evidence is accumulating that individual dispersal strategies are informed in most, if not all, organisms. The acquisition and use of information are traits that may evolve across space and time as a function of the balance between costs and benefits of informed dispersal. If information is available, individuals can potentially use it in making better decisions, thereby increasing their fitness. However, prospecting for and using information probably entail costs that may constrain the evolution of informed dispersal, potentially with population-level consequences. By using individual-based, spatially explicit simulations, we detected clear coevolutionary dynamics between prospecting and dispersal movement strategies that differed in sign and magnitude depending on their respective costs. More specifically, we found that informed dispersal strategies evolve when the costs of information acquisition during prospecting are low but only if there are mortality costs associated with dispersal movements. That is, selection favours informed dispersal strategies when the acquisition and use processes themselves were not too expensive. When non-informed dispersal strategies evolve, they do so jointly with the evolution of long dispersal distance because this maximizes the sampling area. In some cases, selection produces dispersal rules different from those that would be 'optimal' (i.e. the best possible population performance-in our context quantitatively measured as population density and patch occupancy-among all possible individual movement rules) for the population. That is, on the one hand, informed dispersal strategies led to population performance below its highest possible level. On the other hand, un-and poorly informed individuals nearly optimized population performance, both in terms of density and patch occupancy.

“…Thus, the return of individuals not reaching the breeding age is very rare. Among colonially nesting seabirds, it has often been observed that subadults move from one breeding colony to another and their subsequent settlement is non-random (Reed et al 1999). Similar behaviours of subadults of various Sulidae species have been confirmed using GPS tracking (Votier et al 2011).…”

Abstract. The Brown Booby Sula leucogaster is divided into four subspecies and is distributed throughout the tropical and subtropical seas of the world. This species was believed to show little movement and low or no gene flow among populations, however, there exist several records of dispersal and breeding across the East Pacific Basin, both by S. l. plotus and S. l. brewsteri inhabiting the western and eastern sides, respectively. We observed a male of S. l. brewsteri visiting Nakanokamishima, Japan, which is one of the breeding sites of S. l. plotus in the West Pacific. Presumably, it was this same individual that was observed intermittently until 2014 and bred and produced offspring with a S. l. plotus female, adapting to the breeding schedule of the Nakanokamishima population from 2012 to 2014. Another male having a white head and neck was recorded at another location on the island since 2011. Although this male often courted a female, they have not yet formed a pair. These are the first records of S. l. brewsteri breeding behaviour in Japan and provide important ecological information regarding the process of pair formation and breeding at the breeding sites of other S. leucogaster subspecies.
