Spotted Hyena

One of the most interesting animals we encountered in Africa was the spotted hyena. There are four species of hyena: (a) the spotted hyena, the ones we saw; (b) the striped hyena; (c) the brown hyena; and (d) the aardwolf. The spotted hyena is found in Africa, from the Sahel (the transition zone between the Sahara desert and savanna) to South Africa, except for equatorial west and central Africa and much of South Africa (where they have been heavily hunted). The spotted hyena has a strong neck and forequarters that then slope down to an undeveloped hindquarters which are rounded.

It is hard to believe, but it is the second largest carnivore in Africa, after the lion. The spotted hyena has rounded ears

and a relatively short tail with a black puffy end. Its fur can be tan to reddish with irregular black spots that fade with age. It also has five barely distinct bands on the back and sides of the neck and white bands above the eyes.

It has a broad head with rounded ears and large teeth.

Females wear the proverbial pants among this species of hyena. Females are up to 14% larger than males and the alpha female is the biggest and best-fed member of the clan.

In the Serengeti, males average 89 to 121 pounds, while females average 98 to 141 pounds. In Zambia, the averages are 10 to 20 pounds higher than that. Females are as aggressive as males and they have more of a phallus than a vagina. They are more hunter than scavenger and a lone adult can take down a wildebeest. In packs they can take down zebras and larger animals. In the Serengeti and Ngorongoro Crater, wildebeest is the most common pray, followed by zebra and Thomson's gazelles. We learned that hyenas tend to follow leopards and steal their meals. As a result, leopards usually try to drag their meal into a tree so that the hyenas can't steal it. Sure enough, where we saw leopards, we saw hyenas. A female generally has one to two cubs which are born black and the cubs can suckle up to 18 months. 
This female trotted a long distance with her cub in her mouth and past a tree with a leopard in it we were watching. We learned later that the female was attacked by a group of male hyenas which killed the baby. We were told this was done to get the female back into estrus. 
The male plays no role in parenting.

  1. Interesting animal! I didn't know the female was so dominate in this animal.
