Concerns over hyenas biting off buffalo private parts in Aberdare National Park

The Kenya Wildlife service has raised an alarm over unusual incidents of hyenas biting off and feeding on testicles and tails of buffaloes in Aberdare National Park.

The hyenas, according to the KWS officers, are biting off buffalo testicles and tails, a phenomenon said to have resulted in deformities of tens of buffaloes who roam the vast national park with vital body parts missing.

Aberdare National Park KWS Senior Warden Lilian Ajuoga said the phenomenon has been going on since it was first reported in 2008.

“The incidents of hyenas biting off testicles and tails of buffaloes are everyday occurrences in the National Park.  Tens of buffaloes are partly deformed after hyenas chewed off some parts,” Ms Ajuoga said.

She, however, said the incidences were linked to lack of predators like Lions within the National park. The absence of predators, she says, hampers the food chain which places hyenas out of their scavenging role.

Food chain, she says, is vital in an ecosystem in balancing the roles of wild animals.

“In this case, hyenas are forced to hunt instead of scavenging for leftovers that have been left by other predators. This forces them to hunt on easily available things and since they lack the power to strangle, they depend on biting off hanging parts for survival,” she says.

Young male buffaloes, she says, becomes the target as hyenas can easily creep, biting off the testicles and tails especially at night.

“Hyenas literally feast on prey when they are still alive because they cannot kill. In the National Park, hyenas target young buffalo bulls so they can strip off the ‘loose-hanging’ parts,” she says.

Within the National Park, she says although hyenas also hunt other small animals, their lack of speed in hunting other animals like gazelles makes buffaloes a target.

She added that the KWS would count the number of hyenas within the National Park for purposes of management and sustainability.

“We are planning on a doing an animal count so as to establish the number of hyenas for purposes of management to avoid cases of unsustainability. This will also help in boosting survival for both hyenas and buffaloes,” she adds.

Introduction of predators, she says, will also balance the food chain within the National park, which will place hyenas in their rightful position as scavenges, easing their survival as well as allowing buffaloes to sire.

“We are trying to avoid the scenario where buffaloes might not be able to sire in future with their vital organs bitten off,” she adds.

Kenya Wildlife Service Assistant Director in charge of Mountain Areas Simon Gitau said they are also involving researchers to shed light on what might have prompted the hyenas to bite off testicles and tails.

“This thing has been on-going for a while but that does not mean the population of buffaloes is going down. One healthy buffalo with intact organs can still mate with 50 females and successfully sire,” Mr Gitau said.

He said the trend is calling for more researches to shed light on how the incidences can be controlled.
