Category | Behaviour | Description |
|---|---|---|
Agonistic | Mount | A male (author) raises the thoracic region of its body close to another male, flexes the thoracic members, and can stand on the rump of the other male (receptor) to perform the mount; with possibility of penetration or attempt when the receptor moves to any direction to avoid being mounted |
Fight | An animal (author) presses the forehead of another animal (receptor) with its own; both animals apply forward pressure in a vigorous, aggressive manner for an interval, with possible bumps and kicks | |
Headbutt | An animal (author) uses its head to hit the other bull (receptor), forcing the receptor to move at least one step in any direction | |
Affiliative | Head-play | An animal (author) touches its head to the forehead of another animal (receptor), both animals apply forward non-vigorous pressure to the contact point |
