Are seabirds foraging for unpredictable resources
It is generally assumed that the extreme life history traits of pelagic seabirds, such as low fecundity or slow growth of chicks, result from the difficulties obtaining energy at sea fromExpand
Migratory shearwaters integrate oceanic resources across the Pacific Ocean in an endless summer
The extraordinary transequatorial postbreeding migrations of a small seabird, the sooty shearwater, obtained with miniature archival tags that log data for estimating position, dive depth, and ambient temperature reveal that shearwaters fly across the entire Pacific Ocean in a figure-eight pattern while traveling 64,037 ± 9,779 km roundtrip, the longest animal migration ever recorded electronically.

Assessing the impact of climate variation on survival in vertebrate populations
Analysis of long‐term monitoring data at the individual scale is often the only available approach to estimate reliably demographic parameters of vertebrate populations, and statistical procedures used in these analyses are reviewed. Expand
Emperor penguins and climate change
The results indicate strong and contrasting effects of large-scale oceanographic processes and sea-ice extent on the demography of emperor penguins, and their potential high susceptibility to climate change. Expand
How can a pelagic seabird provision its chick when relying on a distant food resource? Cyclic attendance at the colony, foraging decision and body condition in sooty shearwaters
By modelling attendance patterns with an increasing variance in the foraging routine, it is shown that the periodicity of feeding times is retained throughout the chick rearing period, indicating that cyclic attendance at the level of the whole colony is an emergent property of the two-fold foraging strategy of individual adults.

The importance of oceanographic fronts to marine birds and mammals of the southern oceans
This review examines the relative importance to apex predators of the different frontal zones in terms of spatial distribution and carbon flux; 2) the processes that determine their preferential use; and 3) how the mesoscale dynamics of frontal structures drive at-sea foraging strategies of these predators.

Fast and fuel efficient? Optimal use of wind by flying albatrosses
The capacity to integrate instantaneous eco–physiological measures with records of largescale flight and wind patterns allows us to understand better the complex interplay between the evolution of morphological, physiological and behavioural adaptations of albatrosses in the windiest place on earth.

Does Prey Capture Induce Area‐Restricted Search? A Fine‐Scale Study Using GPS in a Marine Predator, the Wandering Albatross
Birds did not show strong responses to prey capture at a large scale, few ARS events occurred after prey capture, and birds did not have high rates of prey capture in ARS, but the most effective search rule was to follow a nearly straight path. Expand
Foraging Strategy of Wandering Albatrosses Through The Breeding Season: A Study Using Satellite Telemetry
It is shown that Wandering Albatrosses use two foraging strategies to cope with the constraints imposed by the different stages of the breeding cycle, the availability of prey, and the distribution of the prey. Expand
Although Wandering Albatrosses are able to provision their chicks at a rapid rate because of the proximity of an abundant resource, birds still have to forage far from the colony to restore their body condition and estimates of energy yield explain this paradox. Expand
