Family group rushing toward an adversary, predator or perceived threat en masse in a highly coordinated manner and with hostile intent. In an Attacking & Mobbing context Group-Advance may be preceded by Freezing, Periscope-Trunk, Bunching, Head-Swinging, Standing-Tall, Reach-Touch and Rumbling.
This Group-Advance by the C family was led by adult female Corajosa, who initiated the advance when we were over 300 meters away on the other side of the pan. She galvanized the others. As they come toward our vehicle you can see her - the tuskless female with the big U-tear in her ear. As they get closer they split into two groups - one bunch with Corajosa and Bullet going on one side of us and another with gf0029 and gf0080 and others going the other way - essentially surrounding us.
