Brutvögel in Sachsen

Der Atlas behandelt 213 aktuelle und ehemalige Brutvogelarten in Sachsen. Hiervon werden 177 Arten ausführlich mit den Schwerpunkten Verbreitung, Lebensraum, Brutbestand, Phänologie und Brutbiologie sowie Gefährdung und Schutz besprochen. Aus drei Zeitebenen liegen landesweite Bearbeitungen der Brutvogelfauna auf Rasterbasis vor. Die Ergebnisse ermöglichten es, in detaillierten Karten Bestandstrends darzustellen und Veränderungen von Verbreitung und Häufigkeit nachzuvollziehen. 293 Fotos veranschaulichen die Vielfalt der Vogelarten und zeigen ihren typischen Lebensraum

Kites Milvus migrans lineatus (Milvus migrans migrans/lineatus) are spreading west across Europe

Europe is commonly occupied by Black Kites of the nominal subspecies Milvus migrans migrans. In recent years, there has been an increase in the number of sightings of Black Kites with morphological features of Milvus migrans lineatus suggesting the spreading of M. m. lineatus and a subsequent hybridization zone between M. m. migrans and M. m. lineatus in a westerly direction from Siberia across continental Europe. Furthermore, it appears that the emergence of Black Kites with lineatus features in Europe coincides with new observations of wintering Black Kites in some areas of southern Europe.</p

Conservation of the Red Kite Milvus milvus (Aves: Accipitriformes) Is Not Affected by the Establishment of a Broad Hybrid Zone with the Black Kite Milvus migrans migrans in Central Europe.

Among Accipitriformes sensu stricto, only a few species have been reported to form hybrid zones; these include the red kite Milvus milvus and black kite Milvus migrans migrans. M. milvus is endemic to the western Palearctic and has an estimated total population of 20-24,000 breeding pairs. The species was in decline until the 1970s due to persecution and has declined again since the 1990s due to ingestion of rodenticide-treated baits, illegal poisoning and changes in agricultural practices, particularly in its core range. Whereas F1 M. milvus × M. migr. migrans hybrid offspring have been found, F2 and F3 hybrids have only rarely been reported, with low nesting success rates of F1 hybrids and partial hybrid sterility likely playing a role. Here, we analyzed the mitochondrial (CO1 and CytB) and nuclear (Myc) DNA loci of 184 M. milvus, 124 M. migr. migrans and 3 F1 hybrid individuals collected across central Europe. In agreement with previous studies, we found low heterozygosity in M. milvus regardless of locus. We found that populations of both examined species were characterized by a high gene flow within populations, with all of the major haplotypes distributed across the entire examined area. Few haplotypes displayed statistically significant aggregation in one region over another. We did not find mitochondrial DNA of one species in individuals with the plumage of the other species, except in F1 hybrids, which agrees with Haldane´s Rule. It remains to be investigated by genomic methods whether occasional gene flow occurs through the paternal line, as the examined Myc gene displayed only marginal divergence between M. milvus and M. migr. migrans. The central European population of M. milvus is clearly subject to free intraspecific gene flow, which has direct implications when considering the origin of individuals in M. milvus re-introduction programs

Effect of Sky Lark plots and additional tramlines on territory densities of the Sky Lark <i>Alauda</i> <i>arvensis</i> in an intensively managed agricultural landscape

<p><b>Capsule:</b> Sky Lark plots and additional tramlines increase Sky Lark <i>Alauda arvensis</i> territory densities in winter crops.</p> <p><b>Aims:</b> To analyse the effects on Sky Lark territory density of Sky Lark plots and additional tramlines in winter cereals and oilseed rape.</p> <p><b>Methods:</b> We mapped Sky Lark territories on fields with Sky Lark plots or additional tramlines as well as on adjacent control sites, from 2010 to 2013 in Saxony, Germany, where agricultural land use is intensive, dominated by winter-sown crops and takes place in large fields.</p> <p><b>Results:</b> In test sites with Sky Lark plots, 5.6 and 3.1 territories per 10 ha were found in the early (April/May) and late periods (June/July) respectively, compared to 3.3 and 1.4 territories per 10 ha in control sites. Sky Lark territory densities in fields with additional tramlines were 1.6 times higher in the early period (4.2 versus 2.6 territories per 10 ha) and 2.2 times higher in the late period (3.6 versus 1.6 territories per 10 ha).</p> <p><b>Conclusion:</b> Sky Lark plots and additional tramlines improve large fields for the Sky Lark and have the potential to increase the Sky Lark population.</p

Spatial variation of rodenticides and emerging contaminants in blood of raptor nestlings from Germany

Badry A, Schenke D, Brucher H, et al. Spatial variation of rodenticides and emerging contaminants in blood of raptor nestlings from Germany. Environmental science and pollution research international. 2022.Wildlife exposures to pest controlling substances have resulted in population declines of many predatory species during the past decades. Many pesticides were subsequently classified as persistent, bioaccumulative, and toxic (PBT) and banned on national or global scales. However, despite their risks for non-target vertebrate wildlife, PBT substances such as anticoagulant rodenticides (ARs) are still permitted for use in Europe and have shown to threaten raptors. Whereas risks of ARs are known, much less information is available on emerging agrochemicals such as currently used PPPs and medicinal products (MPs) in higher trophic level species. We expect that currently used PPPs are relatively mobile (vs. lipophilic) as a consequence of the PBT criteria and thus more likely to be present in aqueous matrices. We therefore analyzed blood of 204 raptor nestlings of three terrestrial (red kite, common buzzard, Montagu's harrier) and two aquatic species (white-tailed sea eagle, osprey) from Germany. In total, we detected ARs in 22.6% of the red kites and 8.6% of the buzzards, whereas no Montagu's harriers or aquatic species were exposed prior to sampling. SigmaAR concentration tended to be higher in North Rhine-Westphalia (vs. North-Eastern Germany) where population density is higher and intense livestock farming more frequent. Among the 90 targeted and currently used PPPs, we detected six substances from which bromoxynil (14.2%) was most frequent. Especially Montagu's harrier (31%) and red kites (22.6%) were exposed and concentrations were higher in North Rhine-Westphalia as well. Among seven MPs, we detected ciprofloxacin (3.4%), which indicates that risk mitigation measures may be needed as resistance genes were already detected in wildlife from Germany. Taken together, our study demonstrates that raptors are exposed to various chemicals during an early life stage depending on their sampling location and underpins that red kites are at particular risk for multiple pesticide exposures in Germany. © 2022.
