Summary: The diet of the tawny owl was analyzed to assess the small mammal communities along the Vistula River. The study found a high species richness of small mammals in the floodplains of the Vistula River and adjacent areas in central Poland. This study is important for understanding the biodiversity along the Vistula River.

Summary: This study examined the behavior of 19 captive tawny owls in familiar and novel environments, and found that color morphs differed in their choice of perches and response to predation risk. Brown tawny owls were more likely to use exposed perches in a novel environment.

Summary: The allocation of resources in reproduction involves a trade-off with self-maintenance such as antioxidant response. Genetic and environmental factors influence the production of GSH in nestlings, and different colored individuals may have varying life-history strategies. Contrary to expectations, dark pheomelanic nestlings did not have higher levels of (ox)GSH compared to light ones.

Summary: The study found that breeding dispersal rates of northern spotted owls increased as invasive barred owl numbers rose, with monitored owl dispersal rates increasing from around 7% to 25% over the study period. Factors such as historical reproduction levels and prior dispersal events influenced breeding dispersal probabilities in the owl population.

Summary: Currently, urban landcover intensification poses a significant threat to biodiversity. Urban sprawl leads to anthropogenic noise and artificial light at night (ALAN), which negatively impact nocturnal wildlife such as avian predators. In this study, we examined the effects of urban and tree cover, traffic noise, and ALAN on the presence of Tawny Owls in Turin, Italy.

Summary: This article demonstrates the dampening effect on small mammal population dynamics and the numerical response of owls in Latvia. The study reveals that the response varies among owl species, with more adaptable species showing increased food niche breadth, while more specialized species experience reduced breeding performance and population decline. It also identifies the carry-over effect of vole abundance on the breeding performance of the eagle owl. The findings highlight the importance of investigating the covariate effects of habitat destruction and the dampening of small mammal populations.

Summary: Top predators are often used as sentinel species in contaminant monitoring due to their exposure and vulnerability. Our research aims to review the spatial variation in contextual parameters in the Tawny Owl, a suitable biomonitor for pan-European monitoring. We found gaps in knowledge about the species ecology and biology, as well as population parameters in certain countries, highlighting the need for a recommended monitoring scheme.

Summary: This study identified a new species of Circovirus in a tawny owl in Italy, with contrasting evidence regarding its definitive host. The virus is phylogenetically closer to mammalian circoviruses, suggesting a micromammal host, but its detection in the spleen supports the tawny owl being its actual host. This discovery adds to the growing number of circoviruses found in diverse hosts and highlights the need for further research to better understand its biology and pathogenicity.

Summary: The distribution and population of Tawny Owls in Israel are influenced by climate and land use. They prefer cool, rainy, wooded areas and occur more often in villages. Climate change poses a greater threat to them than rural development.

Summary: High-precision GPS tagging combined with infrared video recording provided detailed insights into the foraging patterns and vocal activities of spotted owls. The study revealed differences in territorial vocal activity between nonbreeding males and vocal activity among females provisioning fledglings. This technology has the potential to enhance understanding of owl behavior and population dynamics.

Summary: Research suggests that in snowy winters, the grey colour morph of Tawny Owls has a better survival rate compared to the brown (or red) morph, possibly due to their paler plumage providing better camouflage against predation. While the number of snowy days in the previous winter impacts the pre-breeding survival of young red owls, there are only small differences in morph-specific survival under long-lasting winter conditions.

Summary: This study reports the mitochondrial genome of Strix aluco from Leigong Mountain Nature Reserve, Guizhou Province, China, which has a total length of 18,632 bp and includes 37 genes. The study reveals that the common ancestor of Strix diverged during the Pleistocene and the uplift of the Qinling Mountains and climate oscillation in the Pleistocene caused divergence between the northern and southern parts of mainland China.

Summary: Due to regulations, the deposition of most toxic metals and metalloids in Europe has decreased over the past few decades. However, little is known about the impact of this reduction on exposure levels in terrestrial food webs. This study used tawny owls as biomonitoring species to investigate temporal and spatial trends of exposure to these elements. The results showed a significant decline in toxic elements over time, while beneficial elements exhibited fluctuations but an overall decline. The distance to potential sources of contamination influenced the spatial patterns and temporal trends of element concentrations.
