Table 2.

Definition of the five behaviors for classification. Definition adapted from [3,9,17,22,24].

Behavior Description
Walking The head moves forward/backward or sideways for at least two consecutive steps. From one place to another, the legs on the diagonal of the sheep move at the same time. Slow movement during grazing is excluded.
Standing Sheep in standing position. The limbs and head are still or slightly moved, including standing chewing and ruminating.
Grazing Sheep graze with their heads down, chew and move slowly to find grass.
Lying Sheep in lying position. The head is down or up, and still or slightly moving. Chewing and ruminating are included.
Running Sheep run faster to escape obstacles or catch up with other companions. In most cases, two front/rear legs move at the same time, and there is no biting or chewing.
