Water strider (Gerridae) morphology and behavior have become the focus of interdisciplinary research in biological diversification and bio-inspired technology. However, the diversity of behaviors and morphology of the large-sized Gerridae have not been intensely studied. Here, we provide locomotory behaviors and legs' micro-morphology of the large...

Information on the diet of endangered species is crucial in conservation, especially for diet specialists. The Fairy Pitta, Pitta nympha , is classified as “vulnerable species” by IUCN. In a field-based study on the nestlings’ diet and parental care, combined with the existing literature, we confirm pitta’s dietary specialization as vermivory and r...

Eggshell bacterial communities may affect hatching success and nestling’s condition. Nest materials are in direct contact with the eggshells, but the relationships with the eggshell microbiome during incubation have not been fully elucidated. Here, we characterize eggshell and nest material bacterial communities and their changes during incubation...
Article

Ecological specialists utilize a restricted range of resources and have evolved adaptations to exploit their specialized resources. For example, avian insectivores that feed nestlings with grasshoppers, beetles, or moths perform insect prey preparation before feeding nestlings so that the nestlings are able to swallow the prey. This behavior is gen...

Accurate measurements of travel distance and speed are crucial for the analysis of animal movements. Measuring the movements of ants entails measuring the change in locations registered at time intervals. This process involves the dilemma of setting the proper time window: a short time window is vulnerable to spatial errors in observation, while a...

Nest materials are in direct contact with the eggshells, but the relationships with the eggshell microbiome during incubation have not been fully elucidated.

Anti‐predatory strategies of birds are diverse and may include predator‐specific alarm calls. For example, oriental tit (Parus minor) parents can distinguish snakes from other predators and produce snake‐specific referential vocalizations ("jar" call) when a snake poses a threat to their nest. The “jar” call has a very specific function to induce f...
Article
Observations and video documentation of interactions between animals living in dens, cavities, and other enclosed spaces are difficult, but they play an important role in field biology, ecology, and conservation. For example, bird parents visiting nests and feeding their nestlings may provide crucial information for testing of ecological hypotheses...
