Hello once again Fisi lovers!
Many of you may already know that in the society of the
spotted hyena females are socially dominant to males. While aggressions on
females by males are not done frequently there are instances where males show
some aggression. These instances of aggression against females are known as
baitings.
Baitings like instances of mating are not something that we
see everyday in Talek West. However baitings have been making quite the
appearance lately. I decided to investigate this phenomenon and with the help
of a paper (Rare Male Aggression Directed toward Females in a Female-Dominated
Society: Baiting Behavior in the Spotted Hyena by Szykman et al) I found some
answers.
During a baiting several males will come together and attack
a lone adult female. These males lunge, chase, sniff, and sometimes even bite
the female! Females who are ready to produce another litter are more likely to
be baited than females in other reproductive states. These instances of male
aggression are unprovoked. When attacked the female exhibits behavior
characteristic of both submission and aggression. Her ears are flat against her
head, she is low to the ground as if crawling, and her teeth are exposed. She
may also lunge and bite at her attackers.

PCES and TRUS. Both of her cubs are almost ready to graduate.
Males have been shown to bait females of various social
ranks. BORA, like TWST is another female who has undergone a baiting. She is a
wonderful mother to her two cubs GOFA and RUNGU. Both of BORA’s cub have
graduated, making her a prime candidate for another litter. She is lower ranking than TWST and has been
catching they eye of many of the males here in Talek. This increased male
attention has made her the latest target of baitings.

Higher ranking immigrant males participate in baitings more
frequently that lower rankers or natal males (males who are born in the clan).
A few of the males who frequently participate in these
baitings are PENE, ZITI, JUBA, and KHTM.
Participation of natal males in baiting incidents is rare
but it does happen occasionally. PENE and ZITI are both natal males to the
Talek West Clan who have been found at many baiting scenes. These hyenas have
both reached sexual maturity and should be getting ready to disperse (immigrate
to another clan). Females are less likely to mate with males that were around
as they were growing up which is one of the reasons why male hyenas disperse.

While there are many hypotheses about the function of
baitings, the purpose of this behavior is still being examined. Some hypotheses
suggest that baiting is a way for males to show their strength and fitness
while others state it is a form of sexual harassment (Szykman et al). What do
you think is the function of baitings? Is it a chance for the males to show off
their “guns” or are they just being a nuisance?
Interested in learning more about this behavioral
phenomenon? Stay tuned to the MSU hyena blog to see if we can solve this
behavioral mystery.
