The calls of the Blue-fronted Amazon (Amazona aestiva) are described and their possible function within the social organization of the species during breeding and non-breeding seasons are discussed. We identified 9 vocalizations; six ("wak-wak", "wa-wawawa", transiitons, "gu-gugu", guturals, "ka-kaka") were nonspecific and were given in several circumstances: alarm, contact, feeding, and flying. The remaining had specific contexts: "waahh" (agonistic). "grr-uip" (contact in flight), and songs (reproduction-territorial). Vocalization rates increased in alarm contexts and during the non-breeding season, probably as a result of increasing interactions between individuals. The frequency containing the greatest amount of energy was a useful variable to characterize Blue-fronted Amazon calls, particularly at the species level. The most commonly used vozalization, "wak-wak", has structural features that promote directionality and short-range transmission, enhanging its usefulness for the aggregation of individuals. It is suggested songs were derived from a process of repetition and increasing variability from gutural calls. The highly contextual variability of these calls may be due to an incompletely specialized reportoire or a vocal system based upon combinations of calls for conveying messages. |
