This video abstract shows that observations made with a drone suggest that male Risso's dolphins (Grampus griseus) maintain distinct levels of strong associations within their pod, and that position in the group is correlated with measures of sociality. Study performed by K. Hartman, P. van der Harst and R. Vilela in the Azores. This video was produced and edited by Karin Hartman. The production of this video was made possible thanks to the fantastic contribution of the following persons: Zoltan Korai: Animations; Nóra Mészáros: Illustrations; Franka Insinger: Voice-over; Sonja Muda van Hamel/Birdfish: Music; Sound-design: Danny Rosendahl.
