“…Bruck (2013) confirmed that dolphins are capable of long-term social memory spanning decades, and other researchers have found via numerous studies that bottlenose dolphins readily recognize and react to playbacks of the signature whistles of familiar, even related, individuals (e.g., Janik, Sayigh, & Wells, 2006;King, Harley, & Janik, 2014;Sayigh, Esch, Wells, & Janik, 2007). For many species, kin recognition has been documented for aquatic mammals between mother and offspring, siblings, and second-generation relations via visual, vocal and olfactory cues (e.g., Sauvé, Beauplet, Hammill, & Charrier, 2015;Trimble & Charrier, 2011;Wilson et al, 2015), non-kin require social mechanisms or tools to establish and maintain a social relationship with a new conspecific.…”

“…The three calls used as tokens had been previously recorded from three 3-week-old pups: one from the focal pup, one from a coetaneous pup from the same coastal region but different area, and a third one from a pup from a different region. As geography may affect call features in this species (Sabinsky, Larsen, Wahlberg, & Tougaard, 2017;Sauvé et al, 2015), this design tried to ensure that the pup would respond to at least one call type (either very similar or dissimilar to hers), while attempting to minimize habituation (Perry & Renouf, 1988). Mean power intensity was normalized across calls.…”

Alternative mathematical models predict differences in how animals adjust the timing of their calls. Differences can be measured as the effect of the timing of a conspecific call on the rate and period of calling of a focal animal, and the lag between the two. Here, I test these alternative hypotheses by tapping into harbor seals' (Phoca vitulina) mechanisms for spontaneous timing. Both socioecology and vocal behavior of harbor seals make them an interesting model species to study call rhythm and timing. Here, a wild-born seal pup was tested in controlled laboratory conditions. Based on previous recordings of her vocalizations and those of others, I designed playback experiments adapted to that specific animal. The call onsets of the animal were measured as a function of tempo, rhythmic regularity, and spectral properties of the playbacks. The pup adapted the timing of her calls in response to conspecifics' calls. Rather than responding at a fixed time delay, the pup adjusted her calls' onset to occur at a fraction of the playback tempo, showing a relative-phase antisynchrony. Experimental results were confirmed via computational modeling. This case study lends preliminary support to a classic mathematical model of animal behavior-Hamilton's selfish herd-in the acoustic domain.

ObjectivesTiming and rhythm (i.e. temporal structure) are crucial, though historically neglected, dimensions of animal communication. When investigating these in non-human animals, it is often difficult to balance experimental control and ecological validity. Here I present the first step of an attempt to balance the two, focusing on the timing of vocal rhythms in a harbor seal pup (Phoca vitulina). Collection of this data had a clear aim: To find spontaneous vocal rhythms in this individual in order to design individually-adapted and ecologically-relevant stimuli for a later playback experiment.Data descriptionThe calls of one seal pup were recorded. The audio recordings were annotated using Praat, a free software to analyze vocalizations in humans and other animals. The annotated onsets and offsets of vocalizations were then imported in a Python script. The script extracted three types of timing information: the duration of calls, the intervals between calls’ onsets, and the intervals between calls’ maximum-intensity peaks. Based on the annotated data, available to download, I provide simple descriptive statistics for these temporal measures, and compare their distributions.
