Alvina Leche, Auteur ; Eric Gismondi, Auteur ; Monica B. Martella, Auteur ; Arne Korthals, Auteur ; Oliver Krone, Auteur ; Joaquin L. Navarro, AuteurPersistent organic pollutants (POPs) have been identified as a significant threat to environmental health. The presence of POPs was examined in a feral population of Greater Rhea (Rhea americana) established in Germany. Polychlorinated biphenyls[...]
Article
Marc Engler, Auteur ; Oliver Krone, AuteurWe estimated the onset of natal dispersal for a large diurnal raptor with high propensity towards large-scaled exploratory movements during the post-fledging period, the White-tailed Sea Eagle (Haliaeetus albicilla). We analysed GPS tracking dat[...]
Article
Marc Engler, Auteur ; Oliver Krone, AuteurExploratory movements and natal dispersal form essential processes during early life history stages of raptors, but identifying the factors shaping individual movement decisions is challenging. Global positioning system (GPS) telemetry thereby p[...]

Oliver Krone, Auteur ; Norbert Kenntner, Auteur ; Nicole Ebner, Auteur ; Claudia A. Szentiks, Auteur ; Sven Dänicke, AuteurLead poisoning of birds of prey from ingestion of ammunition lead has been well documented. Alternative, lead-free ammunition is widely available, but the toxicokinetics of other metals in birds are poorly understood. We tested the erosion of le[...]
Article
Anna Lena Trinogga, Auteur ; Alexandre Courtiol, Auteur ; Oliver Krone, AuteurAs lead is a heavy metal showing high toxicity for many organisms, its entry in the ecosystem should be minimised. Nevertheless, considerable quantities are deposited in the environment via hunting ammunition. Such practice is responsible for th[...]

Article
Mirjam Nadjafzadeh, Auteur ; Heribert Hofer, Auteur ; Oliver Krone, AuteurLittle is known about foraging strategy and prey choice in large raptor species and how they might change with age and season. Here, we present results about time allocation, foraging pattern and diet selection of adult territorial White-tailed [...]
Article
Mirjam Nadjafzadeh, Auteur ; Christian C. Voigt, Auteur ; Oliver Krone, AuteurMany raptor species are considered to be generalists, taking a range of prey species. However, longitudinal dietary records are often scarce, although necessary for characterizing niche width of species at population and individual levels. Quant[...]
Article
Laura Monclús, Auteur ; Richard F. Shore, Auteur ; Oliver Krone, AuteurLead contamination is a widely recognised conservation problem for raptors worldwide. There are a number of studies in individual raptor species but those data have not been systematically evaluated to understand raptor-wide lead exposure and ef[...]
Article
Oliver Krone, Auteur ; Torsten Stiernberg, Auteur ; Norbert Kenntner, Auteur ; Frieda Tataruch, Auteur ; Juhani Koivusaari, Auteur ; Ismo Nuuja, AuteurEleven white-tailed sea eagles (WSEs) (Haliaeetus albicilla) collected in Finland between 1994 and 2001 were examined for their causes of death, including analyses of ubiquitous environmental contaminants and parasites. Four WSEs died due to ele[...]
Article
Oliver Krone, Auteur ; Anne Berger, Auteur ; Robert Schulte, AuteurFor the first time, we measured the home range size and activity pattern of a White-tailed Sea Eagle (WTSE) by GPS telemetry. Positions were recorded three times a day and the activity pattern were continuously recorded by two acceleration senso[...]
Article
Ernst D. Hegemann, Auteur ; Hermann Knuewer, Auteur ; Oliver Krone, AuteurDuring the breeding season 2003 a clutch (2 male, 3 female) of Sparrowhawks in the county of Warendorf (North Rhine-Westphalia/Germany) was checked for age in order to assess the time of ringing. All nestlings with the exception of a female show[...]
Article
Oliver Krone, Auteur ; Mirjam Nadjafzadeh, Auteur ; Anne Berger, AuteurLocation data of four White-tailed Sea Eagles (Haliaeetus albicilla) (WTSE) from four pairs equipped with GPS data loggers or automated GPS-GSM units and visual behaviour observations were used to record their home range size and territoriality.[...]
