Leur d\u00e9placement \u00e9tait relativement lent pour des baleines \u00e0 bosse, mais il me fallait ajuster sans cesse mon cadrage pour saisir le bon alignement. Pendant quelques instants, les trois animaux se sont parfaitement align\u00e9s dans la lumi\u00e8re de la fin d'apr\u00e8s-midi, offrant une sc\u00e8ne rare o\u00f9 ils \u00e9voluaient de mani\u00e8re parfaitement coordonn\u00e9e.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L'image principale documente une association sociale de courte dur\u00e9e, mais remarquablement stable, observ\u00e9e \u00e0 Rurutu au plus fort de la saison de reproduction.
