Colonial central place foragers can reduce time to locate ephemeral food patches and/or increase foraging rate by following their informed peers, parasitizing direction of returning successful foragers, or being intentionally informed on distant food locations at the colony (e.g. the waggle dance of the honey bee). Ceremonial behaviours may also deliver social foraging information between mates, which can spread inadvertently to neighbours. Here we tested for information display in Cape gannets, Morus capensis, a socially monogamous species, during the elaborate dance ceremony performed each time a partner returns to the nest during the breeding season. We tracked fine-scale foraging behaviour of gannets using bird-borne GPS recorders, and videorecorded their subsequent dance ceremony, which involved up to 14 different displays. As we hypothesized, dance characteristics were associated with foraging trip features. Notably, overall dance duration was negatively linked to foraging trip duration, which was highly positively correlated with foraging range, foraging path length and time spent foraging during the trip. Overall dance duration was also negatively linked with distance to the main foraging grounds. Additionally, the duration of preening behaviour was related to the bearing of the main feeding spot. The latter relationship was supported by a Bayesian model averaging analysis, allowing inferences robust to multiple comparisons. Overall, ceremonial behaviour may provide social foraging information on feeding locations, while evidence for further information transfer to the mate or neighbours was not tested here. Frequent updating on prey spatial distribution, inadvertently communicated or not, should be particularly valuable for predators tracking ephemeral prey patches, providing an additional advantage to colonial living. Our results may have strong implications for cultural evolution in animal societies. %B Animal Behaviour %V 166 %P 95-108 %G eng %U https://www.sciencedirect.com/science/article/pii/S0003347220301718 %0 Journal Article %J Marine Biology %D 2020 %T No way home: collapse in northern gannet survival rates point to critical marine ecosystem perturbation %A Grémillet, David %A Clara Péron %A Lescroël, Amélie %A Fort, Jérôme %A Patrick, Samantha C. %A Besnard, Aurélien %A Provost, Pascal %B Marine Biology %V 167 %8 Jan-12-2020 %G eng %U http://link.springer.com/10.1007/s00227-020-03801-y %N 12 %!

Conversely, predators coping with dynamic prey distributions should diversify their individual diet and/or shift foraging areas to increase net intake. We studied individual specialisation in Scopoli's shearwaters (Calonectris diomedea) from the highly dynamic Western Mediterranean, using daily prey distributions together with resource selection, site fidelity and trophic‐level analyses. As hypothesised, we found dietary diversification, low foraging site fidelity and almost no individual specialisation in resource selection. Crucially, shearwaters switched daily foraging tactics, selecting areas with contrasting prey of varying trophic levels. Overall, information use and plastic resource selection of individuals with reduced short‐term foraging site fidelity allow predators to overcome prey field lability. Our study is an essential step towards a better understanding of individual responses to enhanced environmental stochasticity driven by global changes, and of pathways favouring population persistence. %B Ecology Letters %V 21 %P 1043 - 1054 %8 07-2018 %G eng %U http://onlinelibrary.wiley.com/wol1/doi/10.1111/ele.12970 %N 7 %!

Species distribution models (SDMs) are statistical tools aiming at mapping and predicting species distributions across landscapes. Data acquisition being limited in space and time, SDM are commonly used to predict species distribution in unsampled areas or years, with the expectation that modelled habitat–species relationships will hold across spatial or temporal contexts (i.e., model transferability). This key aspect of habitat modelling has major implications for spatial management, yet it has received limited attention, especially in the dynamic marine realm. Our aims were to test geographical and temporal habitat model transferability and to make recommendations for future population‐scale habitat modelling.

Location

Two contrasted regions of the North Western Mediterranean Sea: the cold and productive waters of the Gulf of Lion, and the warm and oligotrophic waters of Corsica.

Methods

We GPS‐tracked 189 Scopoli's shearwaters, Calonectris diomedea, at four breeding sites during the chick‐rearing period in 2011 and 2012 (418 foraging trips), and analysed their fine‐scale foraging behaviour. We then built colony‐specific habitat models (GAMMs) to test SDM geographical and temporal transferability and investigated the effect of extrinsic (environmental extrapolation) and intrinsic (trip characteristics) factors on transferability.

Results

Scopoli's shearwaters from our four study sites had comparable foraging strategies (as assessed from trip characteristics and isotopic diet tracers). Despite such similarities, SDMs revealed colony‐specific habitat associations. Geographical and temporal model transferability was better within than between regions.

Main conclusions

Crucially, our study illustrates how habitat–species relationships can vary between colonies located <200 km apart, and underlines the effect of spatio‐temporal extrapolation in habitat modelling. We therefore warn that defining adequate spatial scales for model predictions is critical to sound marine spatial planning and conservation. %B Diversity and Distribution %V 24 %P 1772-1787 %8 12/2018 %G eng %U https://onlinelibrary.wiley.com/doi/full/10.1111/ddi.12832 %N 12 %R 10.1111/ddi.12832 %0 Journal Article %J Marine biology %D 2017 %T Spatial overlaps of foraging and resting areas of black-legged kittiwakes breeding in the English Channel with existing marine protected areas %A Ponchon, Aurore %A Aulert, Christophe %A Le Guillou, Gilles %A Gallien, Fabrice %A Clara Péron %A Grémillet, David %B Marine biology %V 164 %P 119 %G eng %U https://link.springer.com/article/10.1007/s00227-017-3151-8#citeas %R https://doi.org/10.1007/s00227-017-3151-8 %0 Journal Article %J Marine Policy %D 2016 %T Seeing the ocean through the eyes of seabirds: a new path for marine conservation? %A Lescroël, Amélie %A Mathevet, Raphaël %A Clara Péron %A Authier, Matthieu %A Provost, Pascal %A Takahashi, Akinori %A Grémillet, David %B Marine Policy %V 68 %P 212–220 %G eng %U https://www.sciencedirect.com/science/article/pii/S0308597X16000671 %R https://doi.org/10.1016/j.marpol.2016.02.015 %0 Journal Article %J Marine biology %D 2016 %T Starving seabirds: unprofitable foraging and its fitness consequences in Cape gannets competing with fisheries in the Benguela upwelling ecosystem %A Grémillet, David %A Clara Péron %A Kato, Akiko %A Amélineau, Françoise %A Ropert-Coudert, Yan %A Ryan, Peter G %A Pichergru, Lorien %B Marine biology %V 163 %P 35 %G eng %0 Journal Article %J Biological Conservation %D 2015 %T Adult and juvenile European seabirds at risk from marine plundering off West Africa %A Grémillet, David %A Clara Péron %A Provost, Pascal %A Lescroël, Amélie %B Biological Conservation %V 182 %P 143–147 %G eng %0 Journal Article %J Animal Behaviour %D 2015 %T Individual repeatability of foraging behaviour in a marine predator, the great cormorant, Phalacrocorax carbo %A Potier, Simon %A Alexandre Carpentier %A Grémillet, David %A Leroy, Boris %A Lescroël, Amélie %K behavioural consistency %K foraging efficiency %K individual flexibility %K individual repeatability %K piscivorous bird %X Intrapopulation variability, especially individual foraging specialization, has been investigated in many species. Nevertheless, the repeatability of foraging behaviour remains poorly understood. In particular, whether individuals differ in their respective degrees of repeatability still remains to be determined. Here, we estimated foraging behaviour repeatability in the great cormorant, at both the population and the individual levels, and assessed the effect of repeatability on individual foraging performance. At the population level, we found that some foraging variables were more repeatable (e.g. departure angle and trip duration) than others (e.g. time spent underwater per trip). At the individual level, we found differences in the degree of repeatability for each foraging variable, highlighting the presence of both highly flexible and highly consistent individuals in the population. The effect of repeatability on individual performance depended on the considered timescale: individual-level repeatability of time spent underwater per dive was negatively related to foraging efficiency while individual-level repeatability of time spent underwater per trip was positively related to foraging efficiency. Overall, our study demonstrates the importance of studying repeatability at the individual level and shows how both flexibility and consistency in animal behaviour shape their ability to extract energy from the environment. %B Animal Behaviour %V 103 %P 83–90 %G eng %U http://www.sciencedirect.com/science/article/pii/S0003347215000652 %R 10.1016/j.anbehav.2015.02.008 %0 Journal Article %J Marine biology %D 2014 %T Irreplaceable area extends marine conservation hotspot off Tunisia: insights from GPS-tracking Scopoli’s shearwaters from the largest seabird colony in the Mediterranean %A Grémillet, David %A Clara Péron %A Pons, Jean-Baptiste %A Ouni, Rhida %A Authier, Matthieu %A Thévenet, Matthieu %A Fort, Jérôme %B Marine biology %V 161 %P 2669–2680 %G eng %0 Journal Article %J Journal of Experimental Biology %D 2014 %T Windscape and tortuosity shape the flight costs of northern gannets %A Amélineau, Françoise %A Clara Péron %A Lescroël, Amélie %A Authier, Matthieu %A Provost, Pascal %A Grémillet, David %B Journal of Experimental Biology %V 217 %P 876–885 %G eng %U https://jeb.biologists.org/content/217/6/876.short %R 10.1242/jeb.097915 %0 Journal Article %J Methods in Ecology and Evolution %D 2013 %T Designing observational biologging studies to assess the causal effect of instrumentation %A Authier, Matthieu %A Clara Péron %A Mante, Alain %A Vidal, Patrick %A Grémillet, David %B Methods in Ecology and Evolution %V 4 %P 802–810 %G eng %U https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/2041-210X.12075 %R https://doi.org/10.1111/2041-210X.12075 %0 Journal Article %J Biological conservation %D 2013 %T Importance of coastal Marine Protected Areas for the conservation of pelagic seabirds: The case of Vulnerable yelkouan shearwaters in the Mediterranean Sea %A Clara Péron %A Grémillet, David %A Prudor, Aurélien %A Pettex, Emeline %A Saraux, Claire %A Soriano-Redondo, Andrea %A Authier, Matthieu %A Fort, Jérôme %B Biological conservation %V 168 %P 210–221 %G eng %0 Journal Article %J Science %D 2013 %T Space partitioning without territoriality in gannets %A Wakefield, Ewan %A Bodey, Thomas %A Bearhop, Stuart %A Blackburn, Jez %A Colhoun, Kendrew %A Davies, Rachel %A Dwyer, Ross %A Green, Jonathan %A Grémillet, David %A Clara Péron %A others %B Science %V 341 %P 68–70 %G eng %U https://science.sciencemag.org/content/341/6141/68 %R 10.1126/science.1236077 %0 Journal Article %J PloS one %D 2013 %T Tracking through life stages: adult, immature and juvenile autumn migration in a long-lived seabird %A Clara Péron %A Grémillet, David %B PloS one %V 8 %G eng %U https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0072713 %R 10.1371/journal.pone.0072713
