Challenges and benefits of using unstructured citizen science data to estimate seasonal timing of bird migration across large scales. [PDF]

PLoS ONE, 2021
Millions of bird observations have been entered on online portals in the past 20 years either as checklists or arbitrary individual entries. While several hundred publications have been written on a variety of topics based on bird checklists worldwide ...

The Influence of Winter and Spring Large-Scale Climate Patterns on the Timing of Male and Female Blackcap Spring Passage at the Baltic Coast [PDF]

Biology
Sex-specific adjustments of bird migration phenology to climate change are understudied. We analysed blackcap migration timing using spring (26 March–16 May) ringing data from Bukowo–Kopań (N Poland) in 1982–2025. We assessed the influence of large-scale

Long-term changes in autumn migration timing of Garden Warblers Sylvia borin at the southern Baltic coast in response to spring, summer and autumn temperatures

The European Zoological Journal, 2023
Many migrant European birds have been departing their breeding grounds earlier in recent decades in response to rising temperatures from climate change.

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.

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 ...

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 ...

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 ...
