Human language and speech are unique accomplishments. Nevertheless, they share a number of characteristics with other systems of communication, and investigators have thus compared them to birdsong and the vocal signaling of nonhuman primates. Partic

There is growing evidence that, during song learning, birds do not only acquire 'what to sing' (the inventory of behavior), but also 'how to sing' (the singing program), including order-features of song sequencing. Common Nightingales Luscinia megarh

This chapter focuses on the acoustic features of laughter. Laughter, like many other human signal behaviours, is a multimodal display composed of visual and auditory signal components. Several studies of the acoustics of laughter have shown that laug

Vocal interactions in songbirds can be used as a model system to investigate the interplay of intrinsic singing programmes (e.g. influences from vocal memories) and external variables (e.g. social factors). When characterizing vocal interactions betw

Alarm call systems can be broadly categorised into functionally referential and urgency based. In the former, different categories of predators evoke structurally distinct call types which elicit different responses also in the absence of the predato

Changes in preference for a specific song-learning context, characterized by close proximity of a tutor, were investigated in the nightingale, Luscinia megarhynchos. Two groups of males were tutored with conspecific song for two periods, days 42 to 5

Semi-free-ranging Barbary macaques (Macaca sylvanus) were observed to utter distinctive calls after disturbances in the surroundings (e.g. presence of a predator, occurrence of some unusual phenomenon). These calls differed from calls given in other

Male blackbirds (Turdus merula L.) were confronted with auditory stimulation which simulated the singing behaviour of a conspecific with a shared vocal repertoire. Simulated interactions: (1) conspecific singing with no particular temporal relationsh

Our study examined whether vocalizations of domestic pigs Sus scrofa domestica provide reliable cues for particular endocrine stress responses. To induce stress responses, we separated subjects individually from groupmates (SEP) and controlled potent
