Abstract

My thesis examines the structure, processing and use of combinatorial structures within the non-songrepertoire of the Western Australian magpie (Gymnorhina tibicen dorsalis). Firstly, I quantitativelyclassified the acoustic units comprising magpie combinatorial structures, finding evidence formultilevel combining in their non-song repertoire. Secondly, I conducted contextual associationanalyses and playback experiments to investigate the function of a frequently produced callcombination and its two constituent calls. Finally, I investigated the relationship betweencommunicative and social complexity, by comparing variation in the frequency and diversity of callcombinations produced across magpie groups of different size and composition.
