Comme les humains, certains animaux non-humains présentent des schémas comportementaux considérés comme des cultures. Le chant des oiseaux, un comportement appris, constitue un bon modèle pour étudier l'évolution de la culture vocale. Le but de cette thèse est de suivre l'évolution culturelle du chant au sein de plusieurs colonies de diamants mandarins (Taeniopygia guttata) fondées par des mâles produisant un chant très similaire après avoir été entrainés avec le même modèle de chant. Deux colonies ont été fondées par des mâles chantant un même modèle de chant, et une colonie a été fondée par des mâles en chantant un autre. Dans ces conditions artificielles, le chant a évolué de telle sorte que la similarité au modèle initial a été maintenu...
