Spatially different annual cycles but similar haemosporidian infections in distant populations of collared sand martins

BMC Zoology, 2021
Background Populations of long-distance migratory birds experience different environments and are consequently exposed to different parasites throughout their annual cycles.

Multi-sensor geolocators unveil global and local movements in an Alpine-breeding long-distance migrant

Movement Ecology, 2023
Background To understand the ecology of long-distance migrant bird species, it is necessary to study their full annual cycle, including migratory routes and stopovers.

Nighthawk: acoustic monitoring of nocturnal bird migration in the Americas

bioRxiv, 2023
Animal migration is one of nature’s most spectacular phenomena, but migratory animals and their journeys are imperiled across the globe. Migratory birds are among the most well-studied animals on Earth, yet relatively little is known about in-flight ...

Age-dependent differences in iris colouration of passerines during autumn migration in Central Europe [PDF]

PeerJ, 2020
Avian eye colour changes with age, but many aspects of this transition are still insufficiently understood. We examined if an individual’s sex, age, species and body condition are related to the iris colour in common migratory passerines during their ...

Genetics and Evolution of Bird Migration.

Annual Review of Animal Biosciences, 2023
Bird migration has long been a subject of fascination for humankind and is a behavior that is both intricate and multifaceted. In recent years, advances in technology, particularly in the fields of genomics and animal tracking, have enabled significant ...

Carry-Over Effects of Climate Variability at Breeding and Non-Breeding Grounds on Spring Migration in the European Wren Troglodytes troglodytes at the Baltic Coast

Animals, 2023
Many studies have linked changes in avian phenology in Europe to the North Atlantic Oscillation (NAO), which serves as a proxy for conditions in western Europe.

Climate in Africa sequentially shapes spring passage of Willow Warbler Phylloscopus trochilus across the Baltic coast [PDF]

PeerJ, 2022
Background Many migrant birds have been returning to Europe earlier in spring since the 1980s. This has been attributed mostly to an earlier onset of spring in Europe, but we found the timing of Willow Warblers’ passage to be influenced by climate ...

Limited potential for bird migration to disperse plants to cooler latitudes

Nature, 2021
Climate change is forcing the redistribution of life on Earth at an unprecedented velocity1,2. Migratory birds are thought to help plants to track climate change through long-distance seed dispersal3,4.

Short- and long-distance avian migrants differ in exercise endurance but not aerobic capacity

BMC Zoology, 2022
Background Migratory birds differ markedly in their migration strategies, particularly those performing short- versus long-distance migrations. In preparation for migration, all birds undergo physiological and morphological modifications including ...
