Demographic response to environmental variation in breeding, stopover and non-breeding areas in a migratory passerine
Demographic rates of migratory species passing through several areas during their annual cycle may be affected by environmental conditions at each of...
-
Isotopic ornithology: a perspective
The use of measurements of naturally occurring stable isotopes of the light elements C, N, H, O, S in avian tissues and their associated foodwebs has...
-
Wintering areas of adult Atlantic puffins Fratercula arctica from a North Sea colony as revealed by geolocation technology
Most seabirds die outside the breeding season, but understanding the key factors involved is hampered by limited knowledge of nonbreeding...

Post-breeding migration of four Long-tailed Skuas (Stercorarius longicaudus) from North and East Greenland to West Africa
The Long-tailed Skua ( Stercorarius longicaudus ) is a specialist predator of lemmings during the summer and hence an important component of the tundra...

Migration within the annual cycle: species, sex and age differences
The three main energy-demanding events in the yearly cycles of birds—breeding, moult and migration—tend to occur at different times of year from one...

Spatial and temporal patterns of habitat use by Eurasian oystercatchers (Haematopus ostralegus) in the eastern Wadden Sea revealed using GPS data loggers
Detailed knowledge on species–habitat relationships is of crucial importance for the understanding of processes in marine ecosystems. Being...

Morphometrics and stable isotopes differentiate populations of Northern Wheatears (Oenanthe oenanthe)
Linking events of breeding, wintering and stopover areas has important ecological and conservation implications for migratory species. To find a tool...

Post-breeding dispersal of Adélie penguins (Pygoscelis adeliae) nesting at Signy Island, South Orkney Islands
ARGOS satellite telemetry and Global Location Sensors (geolocators) were used to identify the moult locations and the winter foraging dispersal of...

Plasticity versus repeatability in seabird migratory behaviour
Pelagic seabird populations can use several discrete wintering areas, but it is unknown if individuals use the same wintering area year after year....
-
Oceanographic characteristics of areas used by Cory’s shearwaters during short and long foraging trips in the North Atlantic
Many breeding seabird species are central-place foragers and constrained to find productive prey patches within their foraging ranges. We assessed...
-
Stable isotopes reveal individual variation in migration strategies and habitat preferences in a suite of seabirds during the nonbreeding period
Information on predator and prey distributions is integral to our understanding of migratory connectivity, food web dynamics and ecosystem structure....

Experimental increase of flying costs in a pelagic seabird: effects on foraging strategies, nutritional state and chick condition
A central point in life history theory is that parental investment in current reproduction should be balanced by the costs in terms of residual...

Short-term effects of data-loggers on Cory’s shearwater (Calonectris diomedea)
We investigated the possible effects of a 12-g data-logger attached to a darvic ring on the performance of Cory’s shearwater ( Calonectris diomedea ,...
