Many animals emit vocal sounds which, independently from the sounds' function, contain
some individually distinctive signature. Thus the automatic recognition of individuals by …

Recent advances in bioacoustics combined with acoustic individual identification (AIID)
could open frontiers for ecological and evolutionary research because traditional methods of …

The ubiquitous anthropogenic low‐frequency noise impedes communication by masking
animal signals. To overcome this communication barrier, animals may increase the …

The ability to recognize and be recognized underlies the social behavior of many animals.
Individual-level recognition holds special importance in intra-specific recognition, where it is …

Aggressive signaling is an important component in animal communication, as it provides an
efficient mechanism for settling conflicts over resources between competitors. In songbirds, a …

Song production across many songbird species is shaped by largely conserved sets of
constraints associated with song control, production, and perception. This chapter …

The most common method used to determine the identity of an individual bird is the capture-
mark-recapture technique. The method has several major disadvantages, eg some species …

In birds, song performance determines the outcome of contests over crucial resources. We
hypothesized that 1) sustained performance is limited within song, resulting in a …

Many species perform social displays that incorporate complex body movements. However,
the reason why such exaggerated behavioural signals evolve in the first place is unclear …

Duets in pair-bonding primates serve as a primary mode of communication between pairs,
and duets may provide cues to conspecifics regarding the calling individual or pair. Here, we …
