Kindred Spirits of the Kalahari
Kindred Spirits of the Kalahari By Christy Bidstrup It is dark, freezing cold, and I need a bathroom. Rubbing the sleep from my eyes, I struggle to orient myself. Now I remember! I am at a research station in the Kuruman River Reserve in South Africa’s Kalahari Desert. I have come to assist in an ongoing study of meerkat behavior as an Earthwatch volunteer. Bundling up for the moonlit walk from my rondoval to the latrine, I am reminded that the word ‘desert’ does not mean hot, it just means arid. We Earthwatch volunteers are a motley group of six women from around the world. Young Evi is a computer expert from Switzerland. Barbara is a retired microbiologist from Australia, Joan is a retired grant writer from Los Angeles and Judy is a retired high school English teacher from New York City. Terri is a wildlife rehabilitator in California and I am a U.S. Government employee from Fairfax, Virginia. We are united by a profound curiosity about our natural world and a willingness to forego the comforts of a leisure vacation for two weeks of roughing it -- trekking for hours on end through thorny brush beneath a blazing sun to observe the communal behavior of small furry creatures about the size of squirrels. Meerkats are unique in that they stand up on their back legs like people to sunbathe and perform sentinel duty. And, aside from finding lizards, millipedes and scorpions to be thoroughly tasty treats, meerkats act a lot like people – disobedient, playful, dutiful, affectionate, vengeful, greedy…well, you get the picture. There is a reason that the new documentary on Animal Planet about these very same animals, Meerkat Manor, is called a soap opera. After a thorough safety and first aid briefing by our Volunteer Coordinator, Anne-Marie, wherein we learn to distinguish puff adders, whose venomous bite precipitates a rapidly radiating necrosis of the tissue, from Cape cobras, whose venom paralyzes the muscles within half an hour, including the diaphragm (and the closest hospital is only 3 hours away over an unpaved road!), we are off to meet the little critters who have no fear whatsoever of such snakes and will mob them if necessary. Meerkats are, after all, members of the mongoose family. The six of us have been divided into two-person teams and are matched up with one of the study’s research volunteers. These young people, mostly from the U.K. and Europe, are very bright, personable and unfailingly polite to tired, novice Earthwatch volunteers (Would you like a spot of tea?). At any given time there may be around 20-30 people at the main research station studying the meerkats, and sometimes yellow mongooses and pied babblers (a raucous black and white bird). The research volunteers are remarkably dedicated, enduring freezing dawns in winter (you must be at the burrow when the meerkats wake up), scorching heat in summer, formidable thorns, poisonous snakes, scorpions (four kinds!) and wind that makes it difficult to steady the scale for weighing. Uncooperative meerkats will obligingly hop in the weighing tray one time and mischievously avoid it the next. And occasionally there is the appearance of a rival meerkat band that prompts a scuffle and chase that forces the volunteer to madly scoop up equipment, backpack, and journal and run pell-mell after squabbling meerkats hightailing it over the next hill. These young people do this for a full year at low pay, just room, board and expenses. Their curiosity, camaraderie and commitment to science are truly awe-inspiring. The Kalahari is breathtaking. The sky is a cloudless cornflower blue. The early morning frost has long since evaporated and the heat has set in. The sand is a bright terra cotta color and dotted with numerous varieties of scrub, all outfitted with very impressive, we-mean-business thorns. Heidi, our research volunteer, is wearing shorts (!) and I salute her youthful resolve to “toughen up” her legs. Thankfully, however, I am wearing sturdy jeans, the relentless sun notwithstanding. After some frustrating fiddling with the well-worn radio tracking equipment, we locate the Whiskers gang. As we slowly approach them, it is fascinating to realize that these are totally wild animals. Although they have been habituated to a special call that allows us to easily walk among them (and they among us, sometimes to the point that I must do a jig to keep from stepping on one), if the research project packed up and left tomorrow, the meerkats would continue on, unfazed, as they have for millennia. There is no domestication or dependency here, only the least intrusive interaction possible to obtain data. The Whiskers are furiously digging, digging, digging. Digging is what meerkats do, and they do it masterfully. In about a minute a meerkat can dig a hole big enough to disappear into, hopefully to back out again with a beetle or juicy larvae of some sort. But many holes are dug in vain and much energy is expended in general foraging, darting down “bolt holes” to evade predators and fights to defend territory. They work hard for sustenance in this hot, hardscrabble landscape and because of this their appetites are seemingly insatiable. I see an adult meerkat succumb to begging and give a young pup a small lizard almost half his size. It takes the pup about five minutes, but he manages to eat the whole thing in one piece, head first. And then, so stuffed he can barely walk, he resumes his insistent begging call for the next meal. Meerkat life revolves around the pups. Only the dominant male and female breed (well, those are the rules anyway), and the entire group is committed to rearing the pups successfully. As the dominant female (Flower, in this case) leads the group foraging, babysitters stay with the pups for their first three weeks spent in the burrow. The female babysitters can even lactate to help feed the pups. Meerkats vigorously defend a territory of about a square mile, although territories tend to overlap at the margins, often precipitating war dances (big hops into the air with tails sticking straight up), frenetic scent marking and fights to ward off intruders. Occasionally, females get pregnant by rogue bachelors that sneak in from other groups for quickie daytime trysts. This is a dangerous mistake. The pregnant female may be killed by the dominant female, but is usually just seriously roughed up and evicted from the group. But eviction is painful for a meerkat as they are very social animals. The human equivalent is shunning. None of the other meerkats will have anything to do with her and she may become debilitated from stress and parasites or be picked off by predators. Overpopulating a group with hungry pups is irresponsible; the desert is harsh and dominant females like Flower must consider the welfare of the group as a whole. If a pregnant female manages to stay in the group long enough to give birth, her pups may be killed by the dominant female. But this outcome is not absolute. Sometimes the dominant female lets them live, but they take a subordinate status to her pups. Sometimes she even forgives the errant female mother if she is sufficiently sorry and obsequious. This is what is fascinating about meerkats; they have rigid rules, but they are often broken and, like us, they cope with the consequences as best they can, sometimes in unpredictable ways. The members of the seven groups of meerkats in the Cambridge University Study led by Dr. Timothy Clutton-Brock all have names (after flowers, writers, composers, you name it!), code numbers and can be told one from the other by variously located spots of hair dye. I am sometimes confused (Oh no! I have been tracking ‘left shoulder, tail base’ instead of the assigned ‘right shoulder, tail base’ for the last ten minutes!) and must repeatedly refer to my cheat sheets to keep them all straight. But the young research volunteers know them all by heart after a couple months. We track their movements with GPS readings every 15 minutes to determine the distance traveled during foraging. They are weighed three times a day—first thing in the morning, at noon and before bedtime -- to determine how much weight is gained during foraging and lost overnight. This is accomplished by luring them into the weighing tray with a sip of water or a bit of hard-boiled egg. Almost everything a meerkat does is either fascinating or adorable and I want to document it all. I find that early morning sunbathing and late afternoon grooming are great times to get photos as meerkats are fairly stationery near the burrow and the angle of the desert sun provides beautiful, dramatic lighting. Not every day is consumed with tracking meerkats. Anne-Marie has us conduct biodiversity surveys and observe other animals that interact with meerkats. One day we document the behavior of drongos, big-headed black birds with forked tails (indicative of their personality!) that stalk meerkats from the branches of trees or bushes and then issue unwarranted alarm calls. When the meerkat drops everything to dash for a bolt hole, the drongo swoops down and steals the meerkat’s hardearned meal. Another day we build crude “bird ladders” from scrap wood and reclaimed nails to place in the open water cisterns dotting the reserve. It seems that birds fly down to take a drink, cannot climb the steep cement walls to get out and drown, fouling the water. Our ladders will provide an escape and help keep the water clean. Installing one we find a large black vulture that has met such an end. I am saddened as I envision his flapping, futile struggle, but it demonstrates clearly that my blisters and splinters will not have been suffered in vain. One night we take a ride standing in the back of an open pick-up truck, gripping an installed railing and dodging thorny branches (this is not the United States with all of its safety rules!), and shine a bright light into the brush to locate wild animals. I am delighted as gnus (wildebeest), gemsbok, duikers, eland, springboks, spring hares, and a huge African owl (two feet high perched!) stare back at us with red or green reflective eyes. Several late afternoons we climb a high, russet sand dune and gaze out across the seemingly desolate landscape at the glorious red-orange sunset while chatting about the day’s work and sipping sundowners. The Kalahari is, indeed, an extraordinary place. There are many special moments, but one stands out. I am reclining quietly with nothing but sun-baked scrub for miles in any direction. Meerkats are busily digging and foraging around me. Then one climbs up on my knee to be sentinel for the group, scanning the horizon and sky for danger. I can feel his tiny claws through my jeans as he stands tall for the best view. He is so close I can see the breeze ruffling his soft fur, a tiny clump of sand stuck to his nose, a thin scar on his left ear. He turns his head to assess danger from another direction, catches my gaze and stares me square in the eyes. After a few moments, he turns away again to scan the horizon. I have been deemed safe. It is difficult to convey the impact of this brief encounter, this momentary communion of an urban human and a wild creature of the African desert. Yes, on one level I suppose it is meaningless and inconsequential. But on another plane it is a moment of pure and perfect bliss – a microcosm of harmony in the universe. For me there is nothing like it in the world. Our final full day has arrived and it is our last few minutes with the meerkats. In the evening they often cuddle together in large clusters, grooming each other and making delightful, soft chirruping sounds. They are tired and sleepy and begin to slowly drip from the cluster, one by one or in twos, down into the burrow for the night. Finally, the last meerkat, standing tall and outlined in brilliant, fuzzy orange with a shadow ten feet long, takes a look in all directions and disappears down the hole. Surprisingly, a couple of minutes later as we are leaving, he pops his head back up and stares at us for several, long seconds before disappearing again for good. I like to think he was saying goodbye. The next morning, as I drag my “rolling” suitcase through the sand toward the SUV for the long, dusty trip to the airport, I am utterly amazed at how sad I am to be leaving. Over these two weeks I have become totally smitten by these charming, human-like animals. Farewell little meerkats.
