Orchestration: The Movement and Vocal Behavior of Free-Ranging Norwegian Killer Whales (Orcinus Orca)

摘要: Abstract : Studying the social and cultural transmission of behavior among animals helps to identify patterns content interaction. Killer whales likely acquire traits culturally based on their stable groups, population-specific feeding behaviors, group-distinctive vocal repertoires. Digital tags were used record movements vocalizations Norwegian killer whales. These carousel feed, corralling herring into a ball before tail slapping, incapacitating eating fish. Periods slapping characterized by elevated movement variability, heightened activity, call types containing orientation cues. Two behavioral sequence preceded tight circling feeding. First, swam directionally in 2 3 instances silent, suggesting that they may have located other foraging groups eavesdropping. Second, tagged made broad horizontal loops as dove manner consistent with corralling. All 4 these occasions accompanied indicating this benefit from communication. whale traditionally been classified discrete types. Using human speech processing techniques, author considered calls alternatively consist shared segments can be recombined form stereotyped variable repertoire. In classification experiment, characterization using whole call, set unshared segments, or yielded equivalent performance. The required less information parse same vocalizations, more parsimonious system representation. This closer examination whales, combined future work ontogeny transmission, will inform our understanding whether how culture plays role achieving behaviors species.
