Early in the morning at low tide these foxes were scavenging out on the sandbar and were observed from a hidden location.
Initially they were about a kilometre away and had no idea they were being watched. As soon as they got within 30 metres they could sense something was wrong! (A big lens sticking out of a saltbush will do that). The image of the fox starring directly into the camera lens was the exact time of dicovery! Net result, foxes exited stage right at a great rate of knots.
