Summary: This study investigated the effects of pest control activities on cavity nesting bird nest boxes. While the density of L. dispar decreased, it had no effect on early broods but had a negative impact on late broods. This impact may be due to increased parental effort from birds in response to caterpillar shortages during the first brood, resulting in a reduced number of second broods.

Summary: Logging can result in changes in bird richness and abundance, but may not affect the functional response to measured traits. Compared to temperate forests, subtropical forests show lower functional richness in bird communities and less impact of logging on functional traits.

Summary: Most studies on biodiversity in natural and human-modified landscapes focus on species occurrence and abundance, but overlook the impact of habitat types on species' breeding requirements. This study examines the effects of habitat conversion on cavity-nesting birds in Northwest Ecuador, finding evidence of cavity limitation in agriculture and suggesting the importance of retaining remnant trees and using nest boxes as conservation strategies in tropical agriculture.

Summary: Many birds are able to quickly adapt to low light intensities in dark nest cavities. A study on budgerigars showed that within the first second of entering a darker environment, they were able to detect and discriminate targets with different luminance levels. The birds' visual system partially adapts to the lower illumination within this short time period, allowing them to safely find and feed their chicks.

Summary: Planting forests can significantly impact the diversity and abundance of pre-existing wildlife, highlighting the importance of understanding these consequences to avoid unintended effects on habitats and conservation populations. Afforestation in lowland areas of Iceland may affect ground-nesting bird species with international breeding populations, potentially leading to consequences throughout their non-breeding ranges in Europe and Africa. Strategic planning of tree-planting schemes is crucial to mitigate the severe impacts observed on populations of ground-nesting birds in open landscapes, particularly in light of Iceland's commitments to species protection and contribution to global migratory bird flyways.

Summary: The Birds and Habitats Directive and Natura 2000 sites are crucial for nature conservation in Europe. However, despite efforts and ambitious targets, freshwater-related species continue to decline. A study on German N2k sites found that land use in the surrounding areas, as well as local habitat conditions, affect freshwater-related species richness. This is especially important for birds in small N2k sites within diverse and patchy landscapes. The findings suggest that future conservation and restoration areas should consider surrounding land use to optimize their impact.

Summary: The article provides an overview of the global spatiotemporal distribution of avian biodiversity, changes in our knowledge of that biodiversity, and the threats driving changes in bird species richness and abundance. It also highlights the need for increased consideration of the social context of bird conservation interventions.

Summary: The research suggests that secondary cavity-nesting birds cover their eggs to prevent nest usurpation by other birds. When the cavity is dark, potential competitors may hesitate to enter due to difficulty in seeing whether a defending nest owner or predator is inside, supporting this hypothesis.

Summary: Nesting cavity diameter influences the body size and performance of M. rotundata, with 7 mm and 8 mm being the optimal sizes for offspring yield and performance respectively. A 5 mm cavity may be optimal for conservation efforts of other cavity-nesting bees.

Summary: This study found that great tits attracted to areas affected by outbreaks of the great web-spinning sawfly experienced fitness detriments characteristic of ecological traps, with lower fledgling numbers and worse fledgling condition compared to tits breeding in healthy forest patches. The lower larval biomass in forest patches damaged by sawflies led to reduced nutritional resources for cavity-nesting birds, highlighting the potential formation of ecological traps by pest insects.

Summary: This study evaluated the use of nest boxes to increase insectivorous bird abundance and biological control in vineyards. Results showed that plots with nest boxes had significantly higher prey removal by birds. The use of nest boxes is recommended as an environmentally-friendly method to increase native predators and enhance biological control in agricultural fields.

Summary: Excavators such as woodpeckers play a key role in maintaining the diversity and abundance of secondary cavity nesters in temperate forests by creating tree cavities, releasing SCNs from nest-site limitation. They leave a legacy of biodiversity at a site by accumulating cavities faster than they become unusable, highlighting their role as ecosystem engineers.

Summary: Urban environments are crucial for biodiversity conservation, with birds capable of surviving and even thriving in cities. However, urbanization poses a threat to bird populations, with introduced species decreasing and native urban exploiters increasing in prevalence in Australian urban areas. Monitoring and conservation efforts are important for the persistence of bird species in urban environments.

Summary: The Tayra is an omnivorous, territorial predator in the Southern Yungas of Argentina, where it was observed preying on the nest of a Blue-crowned trogon. This behavior suggests the Tayra's prospective cognition and ability to remember food sources. This event provides new evidence on Tayra predatory behavior, spatial memory, and cognition.

Summary: Unplanned logging poses a significant threat to forest biodiversity, especially in the Southern Andean Yungas. This study identified specific understory bird species associated with changes in forest structure due to selective logging, and proposed using them as monitoring tools. The research found that certain bird species were linked to unlogged areas with higher tree density, while others were favored by logging activities and visual obstruction in the understory. Threshold abundance levels were also determined for bird guilds in both logged and unlogged forests.

Summary: Logging poses a major threat to bird populations breeding in subtropical forests, as it influences forest structure and nest site selection, ultimately affecting predation rates. Research indicates that predation rates on artificial nests are lower in logged forests compared to unlogged forests, potentially due to better nest concealment and decreased density of generalist predators. Additionally, the density of nestling predators is higher in logging forests, suggesting post-logging effects impact nesting sites and predator density.
