“…Pers + public is the use of both personal and public information (conspecific breeding success) in emigration decisions. Results are shown after 20,000 years over 10 replicates (Boulinier et al, 2016;Ponchon, Aulert, et al, 2017), northern gannets Morus bassanus (Votier et al, 2011), and black-browed albatrosses Thalassarche melanophris (Campioni et al, 2017). Our results finally align with the theoretical study by Delgado et al (2014) which shows that prospecting length (somehow equivalent to our number of prospected patches) decreases with increased mortality costs.…”

“…The establishment of Marine Protected Areas (MPAs) is considered fundamental to future seabird conservation and there is an urgent need to better define at-sea foraging locations and spatial ecology of seabirds, so appropriate and effective management areas can be designated [36, 41, 46, 66]. To date MPA designation has largely been focussed on areas that are important during the breeding season [3, 49]. There is increasing recognition that such designations should capture the interannual variation in distribution associated with fluctuations in environmental conditions, to ensure that MPAs provide robust, long-term protection [3].…”

BackgroundNatural environments are dynamic systems with conditions varying across years. Higher trophic level consumers may respond to changes in the distribution and quality of available prey by moving to locate new resources or by switching diets. In order to persist, sympatric species with similar ecological niches may show contrasting foraging responses to changes in environmental conditions. However, in marine environments this assertion remains largely untested for highly mobile predators outside the breeding season because of the challenges of quantifying foraging location and trophic position under contrasting conditions.MethodDifferences in overwinter survival rates of two populations of North Sea seabirds (Atlantic puffins (Fratercula arctica) and razorbills (Alca torda)) indicated that environmental conditions differed between 2007/08 (low survival and thus poor conditions) and 2014/15 (higher survival, favourable conditions). We used a combination of bird-borne data loggers and stable isotope analyses to test 1) whether these sympatric species showed consistent responses with respect to foraging location and trophic position to these contrasting winter conditions during periods when body and cheek feathers were being grown (moult) and 2) whether any observed changes in moult locations and diet could be related to the abundance and distribution of potential prey species of differing energetic quality.ResultsPuffins and razorbills showed divergent foraging responses to contrasting winter conditions. Puffins foraging in the North Sea used broadly similar foraging locations during moult in both winters. However, puffin diet significantly differed, with a lower average trophic position in the winter characterised by lower survival rates. By contrast, razorbills’ trophic position increased in the poor survival winter and the population foraged in more distant southerly waters of the North Sea.ConclusionsPopulations of North Sea puffins and razorbills showed contrasting foraging responses when environmental conditions, as indicated by overwinter survival differed. Conservation of mobile predators, many of which are in sharp decline, may benefit from dynamic spatial based management approaches focusing on behavioural changes in response to changing environmental conditions, particularly during life history stages associated with increased mortality.

“…In this instance, recommendations were made to extend the marine conservation boundaries (Grémillet et al, ). In black‐legged kittiwakes ( Rissa tridactyla ) and Balearic shearwater ( Puffinus mauretanicus ), existing MPAs were found to encompass 50% of the areas around the colonies used for resting and foraging activities, suggesting it is possible to better position protected areas with detailed information of at‐sea behavior (Meier et al, ; Ponchon et al, ). By identifying areas which are regularly frequented by the Hutton's shearwater, consideration can be made to extend the pre‐existing MPA or to recommend for the establishment of a new MPA area (Taylor, ).…”

The Hutton's shearwater Puffinus huttoni is an endangered seabird endemic to Kaikōura, New Zealand, but the spatial and temporal aspects of its at‐sea foraging behavior are not well known. To identify foraging areas and estimate trip durations, we deployed Global Positioning Systems (GPS) devices and Time‐Depth Recorders (TDR) on 26 adult Hutton's shearwaters during the chick‐rearing period in 2017 and 2018. We found Hutton's shearwaters traveled much further from their breeding grounds at Kaikōura than previously considered, with most individuals foraging in coastal and oceanic areas 125–365 km south and near Banks Peninsula. Trip durations varied from 1 to 15 days (mean = 5 days), and total track lengths varied from 264 to 2,157 km (mean = 1092.9 km). Although some diving occurred in near‐shore waters near the breeding colony, most foraging was concentrated in four regions south of Kaikōura. Dive durations averaged 23.2 s (range 8.1 to 71.3 s) and dive depths averaged 7.1 m (range 1.5 to 30 m). Foraging locations had higher chlorophyll a levels and shallower water depths than nonforaging locations. Birds did not feed at night, but tended to raft in areas with deeper water than foraging locations. Mapping the spatial and temporal distribution of Hutton's shearwaters at sea will be fundamental to their conservation, as it can reveal potential areas of overlap with fisheries and other industrial users of the marine environment.
