Stopover departure decisions in spring: pre-Saharan migrants stay longer and are more selective for favourable wind than trans-Saharan migrants Open
Background Birds that breed in Europe and winter south of the Sahara, so-called trans-Saharan migrants, generally migrate longer distances than pre-Saharan migrants. The latter are expected to be less time constrained during autumn migrati…

Migratory birds can extract positional information from magnetic inclination and magnetic declination alone Open
Migratory birds are able to navigate over great distances with remarkable accuracy. The mechanism they use to achieve this feat is thought to involve two distinct steps: locating their position (the ‘map’) and heading towards the direction…

Highly pathogenic avian influenza causes mass mortality in Sandwich Tern<i>Thalasseus sandvicensis</i>breeding colonies across north-western Europe Open
Summary In 2022, highly pathogenic avian influenza (HPAI) A(H5N1) virus clade 2.3.4.4b became enzootic and caused mass mortality in Sandwich Tern Thalasseus sandvicensis and other seabird species across north-western Europe. We present dat…

A bstract In 2022, highly pathogenic avian influenza (HPAI) A(H5N1) virus clade 2.3.4.4b became enzootic and caused mass mortality in Sandwich terns and other seabird species across northwestern Europe. We present data on characteristics o…

Mass mortality among colony-breeding seabirds in the German Wadden Sea in 2022 due to distinct genotypes of HPAIV H5N1 clade 2.3.4.4b Open
Mass mortality was observed among colony-breeding seabirds in the German Wadden Sea area of the North Sea during the summer months of 2022. Several species’ colonies were affected, most notably sandwich terns ( Thalasseus sandvicensis ), c…

Management guidelines - Mitigation and data collection strategies for avian influenza in bird colonies in the Wadden Sea Open
This document has been developed to guide site managers (including wardens and rangers), bird counters, researchers and other people that will get in contact with colonially breeding birds in the Wadden Sea. The guide provides advice on se…

Do departure and flight route decisions correlate with immune parameters in migratory songbirds? Open
Many songbirds migrate twice a year to exploit seasonally available resources. These journeys are energetically demanding and energy reserves of these small birds are limited. Accordingly, most of the time migrating is spent during stopove…

A magnet attached to the forehead disrupts magnetic compass orientation in a migratory songbird Open
For studies on magnetic compass orientation and navigation performance in small bird species, controlled experiments with orientation cages inside an electromagnetic coil system are the most prominent methodological paradigm. These are, ho…

Stopover departure decisions in songbirds: do long-distance migrants depart earlier and more independently of weather conditions than medium-distance migrants? Open
Background Songbirds following distinct migration strategies (e.g. long- vs. short- to medium-distance migrants) often differ in their speed of migration during autumn and, thus, are assumed to face different time constraints. During migra…

Not just fuel: energy stores are correlated with immune function and oxidative damage in a long-distance migrant Open
In many animals, catabolic and anabolic periods are temporally separated. Migratory birds alternate energy expenditure during flight with energy accumulation during stopover. The size of the energy stores at stopover affects the decision t…
