Movie S1. 3 December 2014 observations: Dedicated observations started at 0918 h. This video begins at 1105 h. Prior to this video, at 1044 h, the male attempted to copulate, unsuccessfully, with a female to the northeast of the pool. The female had an estimated 7-d-old nursing pup and displayed aggression during the mounting. At 1059 h, the male left the area near the pool where he was resting and travelled across rugged terrain to the southwest. He spent 41 s displaying open-mouth threats to an unidentified weaned pup and then engaged in bouts of open-mouth threats with a female with a pup (pup stage unknown) for 4 min 18 s. After resting for 1 min 46 s, he moved back in the direction from which he had come and grabbed a weaned pup in his jaws (11:06:42). From its location and pelage, the selected pup was likely the one from earlier in the encounter. Following this, short examples of transport, submersion, and consumption are provided, the behaviours of which are similar to those described on 2 December. All video clips are taken from one continuous video recording available upon request (2 GB; 48 min long).
