Unravelling migration routes and wintering grounds of European rollers using light-level geolocators
We used light-level geolocators to track the migratory journey of a globally near-threatened trans-Saharan migrant, the European roller Coracias...

Seasonal loss and resumption of circadian rhythms in hibernating arctic ground squirrels
Circadian clocks are near universal among organisms and play a key role in coordinating physiological and metabolic functions to anticipate or...

Morphometrics and stable isotopes differentiate wintering populations of a migratory bird
BackgroundDescribing migratory connectivity in mobile animals is crucial for understanding the selective pressures acting on different populations...

Timing of migration in Common Redstarts (Phoenicurus phoenicurus) in relation to the vegetation phenology at residence sites
Timing the annual cycle according to local conditions is crucial for animals in seasonal environments, because individual resource requirements must...

Sex and migratory strategy influence corticosterone levels in winter-grown feathers, with positive breeding effects in a migratory pelagic seabird
To overcome unpredictable stressful transitory events, animals trigger an allostatic response involving the hypothalamic–pituitary–adrenal cortex....

Mechanisms controling the timing of spring migration in birds
The question “Which factors govern the timing of migration in birds?” has fascinated researchers for a long time. It was initially assumed that avian...

Pattern of non-breeding movements by Stone-curlews Burhinus oedicnemus breeding in Northern Italy
The identification of year-round geographical ranges and the quantification of the degree of migratory connectivity are fundamental to the successful...

Environmental conditions at arrival to the wintering grounds and during spring migration affect population dynamics of barn swallows Hirundo rustica breeding in Northern Italy
Several populations of long-distance migratory birds are currently suffering steep demographic declines. The identification of the causes of such...

Using stable-hydrogen isotopes to reveal immigration in an Arctic-breeding songbird population
BackgroundKnowledge of immigration and emigration rates is crucial for understanding of population dynamics, yet little is known about these vital...

Do ornaments, arrival date, and sperm size influence mating and paternity success in the collared flycatcher?
AbstractMales advertise their intrinsic parental and/or genetic qualities by the size of secondary sexual ornaments. Moreover, they compete with one...

Animal Migration Tracking Methods
The migration of birds has been studied for many years relying mostly on extrinsic passive markers attached to individual animals at the point of...

Seasonal rainfall at long-term migratory staging sites is associated with altered carry-over effects in a Palearctic-African migratory bird
BackgroundAn understanding of year-round habitat use is essential for determining how carry-over effects shape population dynamics in long-distance...
