Fact #1 There are four species of Hyena: spotted, brown, striped, and the aardwolf. All hyenas are usually nocturnal. The spotted hyena is the most well known.
Striped hyenas live in Africa, Arabia, Asia Minor and India in savanna, thorn bush, and stony desert regions. They weigh from 55 to 121 pounds. Striped and brown hyenas are predominantly scavengers, though they do supplement their diets with small prey from insects to foxes.
The aardwolf, also, lives in Africa. It’s main food source is the harvester termite. They also eat insect larvae, and eggs of ground nesting birds. Aardwolf are smaller than other hyena relatives, weighing only 50 and 60 pounds and standing only 15 to 20 inches tall at the shoulder. Except when raising cubs, aardwolf are solitary animals.
Fact #6 Typically silent, a striped hyena usually travels unnoticed, noiselessly moving through the brush. Its loudest call is a rarely heard cackling howl. The hyena makes successive rapid, brief whinnies or cackles when it's excited. Threat displays with rival hyenas begin with a growl rising to a roar, followed by a low, snapping lunge. Spotted hyenas are quite vocal and make a wide variety of sounds, including the "laughing" that has long been associated with their name.
