The Wiley and Surprisingly Cute Hyena

Jessica Vitale is tracking and studying hyenas in the Okavango River Delta. These animals, so often portrayed negatively in popular culture, are actually quite admirable for several reasons, including their social flexibility (even in relation to other species), and their playful tenacity in the face of savage survival.

Greetings from the Okavango! My name is Jessica Vitale, and I am currently a PhD student in the Animal Behaviour and Ecology research group at the University of Nottingham (U.K.), and a National Geographic grantee. I began my field research on spotted hyenas in March 2014, and I am halfway through my first field season. I wanted to take the time to share some of the striking photos I’ve been able to capture of these often misunderstood animals.

My research project focuses on the spotted hyena (Crocuta crocuta), a social carnivore living throughout the continent of Africa.

Spotted hyenas are members of the large predator “guild”, a group of species that compete for resources such as prey and habitat, which also includes the African lion, cheetah, African wild dog, and leopard. My study takes place within the Okavango Delta ecosystem of Botswana, an essential habitat for all five species of the large predator guild. However, there is little known about the behavior of spotted hyenas within this ecosystem.

What we do know is that hyenas live in groups called “clans”, which are made up of multiple females and males following a strict dominance hierarchy. They exhibit behavioral flexibility across populations in aspects such as clan sizes, foraging patterns, and interspecies interactions.

Hyenas raise their cubs in a communal den, where several females bring their cubs of differing ages. Therefore, you can find cubs of all ages and sizes in a single den! (Photo by Jessica Vitale)

Therefore, I am asking a variety of questions about Okavango hyenas, focusing on social dynamics and their interactions with the other large predator species. How many individuals make up a clan? What are their territory sizes? How do individuals associate with other members of their group? How do hyenas interact with other predators? Do hyenas eavesdrop on the sound and smell cues given by other predators?

These photos are all from the same communal den, which is located in the Moremi Game Reserve, and home to four cubs. I camped overnight at this den several times (sleeping on top of my field vehicle) to observe their behavior and capture identification photos.

Part of my research entails determining clan membership, so the main reason that I was visiting this den was to take ID photos to figure out which clan these individuals belong to. Determining clan associations is a long process because hyenas live in a “fission-fusion” society (breaking up groups and recombining frequently), which means that they travel in subgroups of varying size and that the entire clan is rarely seen together at once.

Hopefully soon we will be able to identify each of the animals seen here individually. But it’ll take some time—our database of spotted hyenas in this area is now up to 285 individuals!

    Hi
    They are fascinating survivors, supreme scavengers and they take every advantage offered and skilled predators. I have in an amateur sense, read and watched film about the spotted hyena for years. Last year in Tanzania I was able watch a number of individuals and a Ngorongoro Crater clan at work. I slept
    in a tented camp in the Serengeti and I was terrified hearing hyenas padding and ” laughing” out side and around my tent.They could rip it open and eviscerate me in moments I am certain. But they kindly did not!
    I look forward yo reading your work once published. Let me know when, if you can.
    Kind regards
    Neil Geikie

    A spotted hyena I am.
    Humans say I have awkward form,
    And be a scavenger to damn.
    Like human shape should be the norm?
    Like humans do not steal at will?
    Humans give us little respect,
    But copy us in many skill,
    And are beginning to select
    The female as the better sex
    To lead the future humankind
    Away from mad macho aspects
    That have cluttered the human mind.

    I hear humans give me bad rap.
    I have to laugh how they talk crap.
