This study evaluates how classification model accuracy affects the reliability of detecting avian vocalisation patterns in ecological datasets.

Social environment affects vocal individuality in a non-learning species

This study shows that higher conspecific density increases vocal individuality in little owls, with clumped males showing lower acoustic niche overlap than isolated males.

A ready-to use workflow for automated, sound-based bird identification and localization

This paper presents an automated workflow for bird identification and localization using sound recordings, achieving high accuracy in localizing bird sounds within 5 meters of their true location.

Emotional contexts influence vocal individuality in ungulates

The paper examines how emotional contexts affect vocal individuality in ungulates, finding that negative valence reduces information content but does not eliminate individual recognition.
