title: Data from: An archive of longitudinal recordings of the vocalizations of adult Gombe chimpanzees

description: Studies of chimpanzee vocal communication provide valuable insights into
 the evolution of communication in complex societies, and also comparative
 data for understanding the evolution of human language. One particularly
 valuable dataset of recordings from free-living chimpanzees was collected
 by Frans X. Plooij and the late Hetty van de Rijt-Plooij at Gombe National
 Park, Tanzania (1971–73). These audio specimens, which have not yet been
 analysed, total over 10 h on 28 tapes, including 7 tapes focusing on adult
 individuals with a total of 605 recordings. In 2014 the first part of that
 collection of audio specimens covering the vocalizations of the immature
 Gombe chimpanzees was made available. The data package described here
 covers the vocalizations of the adult chimpanzees. We expect these
 recordings will prove useful for studies on topics including referential
 signalling and the emergence of dialects. The digitized sound recordings
 were stored in the Macaulay Library and the Dryad Repository. In addition,
 the original notes on the contexts of the calls were translated and
 transcribed from Dutch into English.

The Gombe biography contains 13 columns, but the ones most useful for analyzing the vocalizations are the name of the individual (column B), the birth date (column C), the name of the mother (column H) and the sex of the individual (column I). The columns are explained in Strier et al. [1]. 1. Strier, K.B. et al., The Primate Life History Database: A unique shared ecological data resource.

The first column contains the main categories of which the barks, eagle raa, grunts, hoots and screams are the most important. The second column contains the subdivisions of the barks, grunts, hoots and screams. The third column contains all the word variations that were used for each main category or subdivision thereof. Before counting the frequencies of the vocalizations, these word variations were converted into the name of the main category or subdivision thereof.Adults 1This 96K/24bit audio file is 60 minutes long and contains 224 unparsed audio specimens of adult chimpanzee vocalizations.
