Summary: This study examined the relationship between nest structure, nest tree characteristics, and climatic variables in colonies of baya weavers. The findings suggest that nest structure is influenced by the surrounding temperature and that nest structures differ between different locations.

Summary: A study conducted in the Grand-Bassam wetland found that the presence of Quelea erythrops and Ploceus cucullatus in natural habitats and rice fields was influenced by season and rice growth stage. The distribution of both species was affected by field size and rice varieties, with only Quelea erythrops numbers being influenced by plot location and date of spike emergence.

Summary: The study found heavy metal contamination in the excreta of Baya Weaver Birds, with toxic heavy metals such as As, Pb, and Cr exceeding normal levels at different locations. Different types of contaminations at different locations led to the bioaccumulation of various metals in the excreta of the birds.

Summary: The Baya weaver is a bird found in the floodplains of Pakistan, known for its retort shaped hanging nests. This study analyzed the morphometry, haematology, and gut contents of 24 samples of Baya weaver. It was found that there were significant differences in body length and chest circumference between male and female Baya weavers. The preferred food of males was beetles, while females preferred rice.

Summary: The study investigated the entrainment pathway of the circadian photoperiodic system of photosensitive weaver birds and the influence of light wavelength on seasonal responses. The results showed that red light wavelength significantly affected the photoperiodic induction of testicular growth, while blue light wavelength influenced body mass regression.

Summary: Weaver ants in the Ri-Bhoi district of Meghalaya are known for their unique nest-building skills using leaves as their main material. The nests are built on needlewood trees, with a specific pattern of nest size and internal chambers. Activity of the ants peaks at 20-25 degrees Celsius and declines significantly at temperatures of 30 degrees Celsius and above.

Summary: The study found that European orchard bees preferred nesting in paper straws over wooden grooved boards, with the latter resulting in more brood cells and female bees. The nesting success and parasite infestation of bees were influenced by the type of nesting material, with paper straws having a lower rate of mite infestation. Implementing practices such as using paper straws, closing nests near the end of the active nest-construction period, and conserving semi-natural habitat can enhance bee nesting success and reduce parasite infestation.

Summary: The study found that the appearance of Ruppell's weaver eggs varies between individuals but remains consistent within a clutch, with distinctive features. Females typically reject foreign eggs based on differences in brightness and spotting distribution compared to their own eggs.

Summary: Reducing material waste and computation time is the main objective in cutting and packing problems. This paper proposes a new solution for the nesting problem by first grouping the items to be nested and then arranging them. A novel concept, Geometrical Compatibility Index (GCI), is introduced and modeled as bidirectional weighted edges of a graph. Graph neural networks are trained to learn GCIs and a capacitated vehicle routing problem graph is used to group the items into clusters.

Summary: Nests are crucial for the reproductive success of many animals, and cognitive abilities play a significant role in various nesting behaviors. This review examines the evidence linking cognition to nesting behaviors across different taxa and discusses how cognitive abilities can enhance nesting success. The review also emphasizes the importance of combining experimental and comparative research to understand the evolutionary pathways underlying the associations between cognitive abilities and nesting behaviors.

Summary: Reproductive timing plays a crucial role in determining the reproductive success of solitary bees in subalpine environments, with bees nesting earlier in the season exhibiting greater reproductive output. Floral abundance positively affects reproductive output, while temperature influences nesting rate but not overall reproductive success. Bees that initiate nesting early and sustain activity for a longer period have the highest reproductive output.

Summary: In the sexually monomorphic Hooded Dotterel species, male birds tend to spend more time incubating at night and less time during the day, despite no obvious differences in size or color between males and females.

Summary: The study "Nesting Ecology of Spotted Thick-knee in an Urban Mosaic Landscape in Pietermaritzburg, South Africa" examined the nesting behavior of the bird species in urbanized areas. The research found that Spotted Thick-knee showed preferences for certain habitats and nest sites, with successful nesting outcomes being significantly higher than failed outcomes. Incubation activity was longer during the day and negatively impacted by disturbance in human-modified habitats.

Summary: This perspective article defines and discusses the concept of using a "village" approach when working with families facing multiple adversities. It provides an overview of the village concept and its historical background, and emphasizes the need to move past a siloed, professional centric approach in working with families. The article also presents potential principles for the village to work with families in adversity and includes two case studies as examples.
