Méthode télémétrique d’enregistrement individuel des vocalisations. Application à Cercocebus albigena

A telemetric device has been designed which allows simultaneous though independent recording of the vocalizations of different individuals within the same social group. Each animal carries around the neck a small microphone (F.M.) adjusted on a definite frequency. The receivers are tuners. The records can be made by multi-track recorders on magnetic tape or on paper recorder. Such a technique allows a qualitative and a quantitative analysis of vocal behaviour to be made for each sex, age-and status categories, in response to specific stimulating situations.Gautier Jean-Pierre, Deputte Bertrand.
