Summary: A video shot by a mobile phone on May 26, 2021 incidentally recorded a magpie preying on a fledgling Daurian redstart, providing direct evidence for magpie predation. The video also indicates that predation is an important factor affecting fledgling survival, suggesting that the survival of fledglings should be considered in evaluating bird breeding success. The fledgling was approximately 13 days old and on its first day out of the nest when it was preyed upon by a magpie 10 meters away from the nest, despite strong defensive behavior from the female.

Summary: The decline of terrestrial predators is changing predator-prey interactions, but we still don't fully understand how removing predators affects prey behavior.

Summary: The nonconsumptive effects of predation on antibiotic ecotoxicity were investigated in this study. The results showed that predation risk had a significant impact on the toxicity of one antibiotic but not the other. It also had additive or synergistic effects on antibiotic ecotoxicity depending on the antibiotic properties and exposure concentrations. This study highlights the importance of considering the nonconsumptive effects in the evaluation of environmental contaminants.

Summary: The study found that seasonal ecological disturbances can influence predator activity and create predictable patterns of risk for prey. However, the interaction between human recreation and seasonal risk landscapes and antipredator behavior is still not well understood.

Summary: The study found that the activity patterns of snowshoe hares and Canada lynx are not necessarily related to predation risk, and lynx can still prey on hares during the daytime when hares are inactive. This suggests that the overlap of predator-prey activity may not always be a reliable proxy for predation risk, highlighting the need to examine the spatio-temporal behavior of predator and prey to improve our understanding of predation risk.

Summary: Begging behavior in nestling birds has both benefits and costs, as it helps them communicate with their parents but also attracts predators. However, human-associated noise can disrupt communication and the ability of predators to locate nests. The study found that human noise can disturb nest predators and influence their behavior.

Summary: The study aimed to estimate the local Magpie population size in a medium-sized city in Poland (Gorzow Wlkp.) and provide detailed information on nest site selection. The Magpie population has adapted to urbanization factors and chosen conifers as nesting sites in highly anthropogenic habitats.

Summary: The study found higher levels of oxidative stress in hens bred in intensive farming environments compared to those in rural conditions, possibly due to higher stocking density and dust levels indoors. Additionally, a positive correlation between total white blood cell count and oxidative stress was found in magpies, with higher d-ROMs and OSI levels in subjects with total WBC counts above the median value.

Summary: The study identified corvids as the main culprits of damage to maize fields in northeastern Italy. The presence of nearby roosting areas with trees higher than 7 meters increased the risk of bird damage fivefold. No-tillage soil management was associated with a higher risk of bird damage, while naturally derived bird repellents in seed coatings decreased the risk of damage to maize by birds.

Summary: The study found that pikas in E. nutans habitat exhibited faster running speeds, shorter alert distances, and higher vigilance, indicating a higher perceived predation risk for pikas in this habitat.

Summary: The Azure-winged magpies showed a certain level of cognitive ability in causal cue tasks, but they lacked a true understanding of causality and completed the tasks through trial-and-error learning.

Summary: Many animal species protect their eggs against predators, and some species take advantage of this by adding their eggs to those of the protecting species. We studied two tiny predatory mite species that share a food source and face intraguild predation, and found that one species acts as a brood parasite by adding its eggs to the eggs of the other species. The brood parasite prefers to add its eggs to the eggs of the protecting host species rather than another non-protecting mite species, and this behavior only occurs in the presence of egg predators.

Summary: Carcasses can attract facultative scavengers and predators, increasing predation risk for other species in the area. This risk is higher in low productivity environments, particularly when humans contribute to carcass production and invasive species are involved.

Summary: The study found that death-feigning behavior in littoral cladocerans effectively reduced predation rate by odonate larvae. The results suggest that death-feigning serves as an adaptive behavior to reduce mortality risk in littoral cladocerans under predation by predators that detect prey using mechanical cues such as those of vibrational currents.
