“…It has been demonstrated in other contexts that an audiovisual stimulus is more attractive and more appetitive than a visual one. This is true in young nidifugous (Brown, 1975; Ewing, Ewing, & Vanderweele, 1975) and the influence of auditory stimulation has been interpreted in terms of arousal (Brown, 1977). The preference for the audiovisual stimulus is true also in adult non-nidifugous birds (Delsaut & Roy, 1980a,b).…”

Several recent studies have emphasized the role of the maternal call in the attachment process in young nidifugous birds. Prenatal auditory stimulation (audition of sibling calls or self perception) is a determinant factor in the development of the attractiveness of the maternal assembly call. However, little is known about the role of sibling calls after hatching. In particular, they may be involved in attraction between broodmates and, in this way, they may compete with the maternal call during the development of attachment. These experiments were designed to test the value of postnatal audition of sibling calls (C). Several groups of chicks were placed in an operant conditioning paradigm in which the instrumental response allowed the birds to receive either auditory, visual or audiovisual stimuli. Results demonstrated that audition of sibling calls is appetitive but, surprisingly, the chicks did not evince a clear-cut choice for this stimulus over audition of a pure tone (T). Moreover, chicks were tested in a choice situation between two audiovisual stimuli. The visual stimulus was the vision of their own image in a mirror (V). In this choice situation between "V + C" and "V + T," chicks did not choose the "V-l-C" stimulus significantly more. Thus, these data, without denying communicative value to sibling calls, support the hypothesis that they do not play an important role in attraction between broodmates and that the main effect of their audition is an activating one. RESUME: Chez le jeune nidifuge, le role du gloussement maternel dans le processus d'attachement filial est bien connu. Plusieurs etudes recentes ont montre que les stimulations auditives survenant durant la periode prenatale (autoperception et audition des cris des autres embryons) constituent un element determinant dans le developpement du caractere attractif de ce gloussement. Peu de choses, cependant, sont connues sur le role des cris des autres jeunes apres I'eclosion. En particulier, il pourraient etre impliques dans les processus d'interattraction entre les jeunes d'une meme couvee. Ceci pourrait done les faire entrer en competition avec le cri maternel au cours du developpement de I'attachement filial. Ces experiences ont ete construites dans le but d'etudier la valeur de ces cris apres I'eclosion. Plusieurs groupes de poussins ont done ete places dans une procedure de conditionnement operant dans laquelle la reponse instrumentale permettait aux sujets d'obtenir, selon les cas, un stimulus visuel, un stimulus auditif ou encore un stimulus audiovisuel.

“…A possible case may be during play as exemplified by MARLER (1977 b). EVANS 1973;EWING et al 1975;GOTTLIEB 1968GOTTLIEB , 1971GRIER et al 1967;HESS 1972; However, it seems inadequate to say that the hen communicates with her unhatched chicks about absent items. Disclosed from the normally associated behaviour as well as from adequate extcrnal referents, the hen gives almost all vocalizations of tlic repertoire, although some of them are slightly modified.…”

“…Experiments confirm that imprinting and learning can already occur in the egg: after prenatal acoustical stimulation, chicks respond preferentially to the familiar stimulus (e.g. EVANS 1973;EWING et al 1975;GOTTLIEB 1968GOTTLIEB , 1971GRIER et al 1967;HESS 1972; However, it seems inadequate to say that the hen communicates with her unhatched chicks about absent items.…”

The vocal repertoire of guinea fowl was studied in small social groups of birds. Acoustic properties of calls and the concomitant behavioural situation were analyzed in detail in order to reveal the messages transferred by the signals, and the principles of coding used to encode these messages. Such knowledge allows an adequate interpretation of the animal's communication, its competence as well as its limits. Furthermore, indications are provided of neural mechanisms which are required for the perception and discrimination of different, biologically relevant acoustic signals. Zusammenfassung Im Laufrepertoire des Perlhuhns können fünf akustische Grundstrukturen (“characteristic dimensions”) unterschieden und als Lautgruppen definiert werden, die fünf generellen Verhaltenstendenzen zugeordnet sind: — Langsame Frequenzmodulationen von “peep calls” signalisieren allgemeine Aktivität. — Rasche, periodische Frequenzmodulationen von “trill calls” begleiten gezielte Aufmerksamkeit, die durch äußere Reize hervorgerufen wurde. — Verrauschte harmonische Spektren mit tiefer Grundfrequenz in “noisy calls” weisen auf aggressive Interaktionen. — Harmonische Spektren mit tiefer Grundfrequenz und scharf begrenzten Formanten in “squeal calls” begleiten defensives Verhalten. — Harmonische Spektren mit hoher Grundfrequenz und Amplitudenmodulationen in “harmonic calls” weisen auf einen Sender, der zu sozialen Interaktionen bereit ist. Jede der fünf Lautgruppen läßt sich in mehrere Lauttypen unterteilen (charakterisiert durch unterschiedliche parametrische Bereiche der “characteristic dimension” oder zusätzliche akustische Dimensionen), die jeweils unterschiedlichen Aspekten einer allgemeinen Verhaltenstendenz zugeordnet sind. Obwohl der größte Teil des Repertoires graduiert ist (d. h. zwischen den Lauttypen bestehen keine abrupten akustischen Grenzen), zeigen die Antworten der Empfänger, daß sie die verschiedenen Lauttypen unterscheiden. Sie reagieren adäquat entweder auf den Sender oder auf offensichtlich erwartete Außenreize. Dies führt zum Schluß, daß Nachrichten über die Verhaltenstendenz des Senders und seine Artzugehörigkeit (für einige Laute noch detaillierter sein Geschlecht, seinen Status, seine Individualität) übertragen werden, sowie über das Vorhandensein bestimmter Klassen von Außenreizen. Außenreize werden vom Sender subjektiv klassifiziert, entsprechend ihrer augenblicklichen Bedeutung für den Sender.
