The paper investigates how greylag geese use vocal signals to coordinate flight initiation, finding that caller number and identity influence flight success and group size.

The paper examines how sociability, rather than emotions, influences the acoustic structure of sheep bleats during social challenges.

This study shows marmoset phee calls encode external events like food context beyond emotional arousal and valence, even without an immediate stimulus.

This study examines how negative arousal in lambs is reflected in their vocalizations and physiological responses, finding that bodily activation correlates with call characteristics, while eye temperature changes depend on behavior and individual traits.

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

The paper evaluates machine learning methods for caller identity classification in mammalian vocalizations, finding Mel-frequency cepstral coefficients and random forests provide consistent results across datasets.

This study shows that little auk social calls retain individual information over long distances, with negligible information loss down to the hearing threshold.
