Do sperm whales share coda vocalizations? Insights into coda usage from acoustic size measurement

摘要: Group-specific communication signals are found in many group-living species. One example is group variation the production of codas, which short stereotyped patterns clicks produced social contexts, by sperm whales, Physeter macrocephalus. However, little known about how codas used groups and individuals. We multipulse structure whale to estimate size animals producing codas. Recordings a single unit containing nine largely unrelated made over 1-month period yielded 879 32 distinctive types. an automatic technique measure interpulse interval these because closely related animal. Ninety-four had sufficiently accurate measurements be included further analysis. Modes distribution showed that more than one animal was Comparing within coda types revealed several were Thus, recorded from represent shared repertoire, whereby not limited between individuals unit.
