Monitoring haemosporidian parasites in birds is essential to comprehend the dynamics of avian malaria, a disease that significantly affects bird populations worldwide. This study concentrated on the prevalence and diversity of haemosporidian parasites in 198 specimens from two subspecies of the Eurasian bluethroat (Luscinia svecica), aiming to explore the genetic diversity and species richness of haemosporidian fauna across the host populations. By utilizing next-generation amplicon high-throughput sequencing (NGS), we observed a marked increase in the detection of haemosporidian diversity, revealing cryptic variants and species previously unidentified by Sanger sequencing.

- The use of tracking devices, particularly miniature light-level geolocators, has become common in studying the movement patterns of small bird species, revealing previously unknown migratory behaviors.
- A review of data from 549 studies found a weak negative impact of geolocator tagging on apparent survival rates, especially in smaller species and those with heavier device loads.
- The findings suggest that while geolocators can be beneficial for studying small birds, researchers must carefully consider the potential ethical implications and balance them with scientific value in future studies.
