Abstract Aim Knowledge of broad‐scale biogeographical patterns animal migration is important for understanding ecological drivers migratory behaviours. Here, we present a flyway‐scale assessment the spatial structure and seasonal dynamics Afro‐Palaearctic bird system explore how phenology environment guides long‐distance migration. Location Europe Africa. Time period 2009–2017. Major taxa studied Birds. Methods We compiled an individual‐based dataset comprising 23 passerine near‐passerine...
In many taxa, the most common form of sex-biased migration timing is protandry-the earlier arrival males at breeding areas. Here we test this concept across annual cycle long-distance migratory birds. Using more than 350 tracks small-bodied trans-Saharan migrants, quantify differences in male and female schedules for proximate determinants sex-specific timing. autumn, started about 2 days earlier, but difference did not carry over to non-breeding sites. spring, on average departed from...
Abstract Aim Despite the complexity of population dynamics, most studies concerning current changes in bird populations reduce trajectory change to a linear trend. This may hide more complex patterns reflecting responses changing anthropogenic pressures. Here, we address this by means multivariate analysis and attribute different components dynamics potential drivers. Location Czech Republic. Methods We used data on trajectories (1982–2019) 111 common breeding species, decomposed them into...
Migratory connectivity describes to which degree different breeding populations have distinct (non‐overlapping) non‐breeding sites. Uncovering the level of migratory is crucial for effective conservation actions and understanding evolution local adaptations routes. Here we investigate migration patterns in a passerine bird, great reed warbler Acrocephalus arundinaceus , over its wide Western Palearctic range using geolocators from Spain, Sweden, Czech Republic, Bulgaria Turkey. We found...
Migratory birds often move significantly within their non-breeding range before returning to breed. It remains unresolved under which circumstances individuals relocate, whether movement patterns are consistent between populations and what degree the benefit from intra-tropical (ITM). We tracked adult great reed warblers Acrocephalus arundinaceus a central southeastern European breeding population, either stay at single site, or show ITM, i.e. second site. related ITM normalized difference...
Introduction: Bird populations reflect the influence of major environmental changes, and analysis their long-term population trends concerning species-specific ecological traits can provide insight into biologically relevant impacts such changes. In this respect, nest site is a particularly informative trait because ground-nesting bird species are more prone, in contrast to nesting above ground, predation which be linked various drivers including intensification agriculture or woodland...
Abstract To develop effective conservation measures, it is crucial that we understand how ecological and life‐history traits relate to risk of species extinction. Through the use phylogenetic generalized least‐squares regression, this study assesses relative importance habitat specialization, life history, migration strategy climatic niche as predictors national threat level for 86 passerine bird breeding in C zech R epublic. We found that, after controlling variation distribution, slow...
Changes in bird populations can be described as simple changes abundance or density of individuals or, larger areas, distribution population indices. Although these measures describe different aspects change, they are often used interchangeably when discussing the relationships between various predictors found studies. This hampers a meaningful comparison results, because it is unclear which differences studies biologically relevant and just methodological artifacts, caused by nature to...
Understanding why populations of some migratory species show a directional change over time, i.e. increase or decrease, while others do not, remains challenge for ecological research. One possible explanation is that with smaller non‐breeding ranges may have more pronounced population trends, and their are thus sensitive to the variation in environmental conditions quarters. According serial residency hypothesis, this sensitivity should lead higher magnitudes (i.e. absolute values) trends...
Dozens of studies have documented that brood parasites are well adapted to a parasitic lifestyle but not all parasitism events successful. Co‐evolution between and their hosts is dynamic process so it reasonable expect female parasite may commit errors during egg deposition by laying her eggs outside the period host, with consequent impacts on fitness. Using an extensive dataset from long‐term study, we evaluated egg‐laying patterns related timing in Common Cuckoo Cuculus canorus (hereafter...
ABSTRACT Aim Ongoing climate changes represent a major determinant of demographic processes in many organisms worldwide. Birds, and especially long‐distance migrants, are particularly sensitive to such changes. To better understand these impacts on migrants' breeding productivity, we tested three hypotheses focused (i) the shape relationships with different variables, including previously rarely quadratic responses, regional differences predicted by (ii) mean climatic conditions (iii) rate...
