Aardwolves scent-mark their territories, a behavior sometimes called “pasting”.
When scent-marking, aardwolves first straddle a grass stalk, then rapidly squat while wiping a smear of secretion, approximately 6 millimeters in length, onto the grass. They excrete a yellowish-orange secretion from the anal gland that turns black with oxidation upon exposure to the atmosphere.
Both sexes scent-mark, although males mark more frequently than females, pasting on average more than two times per 100 meters.
Scent-marking is a behavior shared with other hyaenids.
