Flying over the open sea is energetically costly for terrestrial birds. Despite this, over-water
journeys of many birds, sometimes hundreds of kilometres long, are uncovered by bio-…

Migratory animals are affected by various factors during their journeys, and the study of
animal movement by radars has been instrumental in revealing key influences of the …

Billions of migrating birds travel between their breeding and over-wintering areas twice a
year, encountering various environmental conditions along their migration routes. Wind is of …

Most seabirds are diurnal foragers, but some species may also feed at night. In Peruvian
pelicans (Pelecanus thagus), the evidence for nocturnal foraging is sparse and anecdotal. We …

Human disturbances are increasingly becoming a conservation concern for many
populations of colonial seabirds. Colonially reproducing species are particularly vulnerable to …

Studying the causes and consequences of route selection in animal migration is important
for understanding the evolution of migratory systems and how they may be affected by …

Atmospheric conditions are known to affect flight propensity, behaviour during flight, and
migration route in birds. Yet, the effects of fog have only rarely been studied although they could …

Recent biologging technology reveals hidden life and breeding strategies of nocturnal
animals. Combining animal movement patterns with individual characteristics and landscape …

Background Millions of birds travel every year between Europe and Africa detouring ecological
barriers and funnelling through migratory corridors where they face variable weather …

Abstract Changes in climate and weather variability are having global impacts on the lives
of organisms, particularly on upper trophic-level predators such as pelagic seabirds. In the …
