Bird songs differ widely among species and can show peculiar phenotypes, such as extreme or unusual sound frequencies for a species’ body size. Although birds

Diverging needs often occurs among group members, prompting group-living animals to engage in collective decision-making, such as coordinating collective movement. Existing models classify these decis...

Humans and other-than-human-animals (animals) share spaces, food, and lives. This gives rise to possibilities of interspecific learning, social facilitation

Vocalisations are known indicators of emotional arousal in animals, but their assessment using simultaneously collected physiological and behavioural …

Large mammal species are declining globally, and zoo populations may help support or re-establish wild populations through reinforcement or reintroduction.

Investigating how animals perceive and interpret emotional signals across a variety of species is essential for deepening our understanding of the complexities underlying animal communication and soc...

Automated acoustic analysis is increasingly used in animal communication studies, and determining caller identity is a key element for many investigations.

For over 5,000 y, chanting has been practiced across many Western and Eastern traditions. However, there is hardly any empirical research on 1) whe...

Rorqual whales exhibit foraging plasticity to maximize their energy intake and reduce the cost of feeding manoeuvres. Bryde’s whales are known for their

Synanthropes are known for their remarkable adaptability to coexist with humans, yet increased visibility exposes them to significant threats, such as hunting

Highlighted Article: Novel aerial photogrammetry methods reveal that smaller cetaceans rely on physiological and morphological adaptations to reduce heat loss whereas larger species offset heat loss b...

There is a vast and ever‐accumulating amount of behavioural data on individually recognised animals, an incredible resource to shed light on the ecological

Nursing behaviour and the calling-to-nurse sound are crucial indicators for assessing sow maternal behaviour and nursing status. However, accurately i…

Biphonation, defined as the simultaneous production of two distinct, non-harmonically related fundamental frequencies, has traditionally been viewed as an anomaly or a by-product of vocal pathology. R...
