Do hyenas hunt?

yes.in groups
I would classify hyenas as being more opportunist than hunter, as they are the best in the art of tribal scavenging. They are bullies and pro's at intimidating an animal who's distracted by chowing down on a fresh kill. Hyenas can be pests until the feasting animals give up and let the hyenas have the kill.

When they're in pack mode, they think nothing of the danger of taking a lion or lionesses meal, they think only of the meal.

When it comes to hunting they are not the most aggressive hunters, but because of their scavenging practices they will probably never go hungry.
