Over a decade ago now, Dr. Lucy King developed the beehive fence as an elephant deterrent, capitalising on a then-recent discovery that African elephants avoided African honeybees (Vollrath & Douglas-Hamilton, 2002). The beehive fence is a relatively simple, inexpensive deterrent, aiming to be a tool that communities can use independently following set-up. The basic premise is that a series of beehives surround an area to be protected from elephants, and if elephants attempt to enter, they will disturb the beehives, causing the colonies to swarm (refer to King et al. 2009; 2017 for more details). It should come as no surprise, that the success of multiple beehive fence trials in Africa, led to a curiosity as to whether this technique could also help Asian communities experiencing comparable levels of crop-raiding.
Until the recent COVID-19 epidemic halted travel around the globe, the island of Sri Lanka thrived on tourism. A big part of the country’s GDP is attributed to tourism. According to Sri Lanka Tourism Development Association, 783,000 tourists visited Sri Lanka’s national parks in 2018, which is roughly 38% of the travelers who entered the country. The parks earned over 2 billion rupees (over $11 million USD) in entrance fees alone. Clearly, elephants have a huge economic value (more about this here).
We’ve temporarily halted field work due to the pandemic. So, we thought this was a good time to bring you some stories from our archives of field notes! In honor of Mother’s Day, here’s an incident that helped us appreciate just how little we understand about what goes on beneath the surface of an elephant’s mind. Happy Mother’s Day!

Can you tell what’s going on in this video? Well, if you know the elephants individually, there’s quite an intriguing story behind it. Read on to see what’s happening, and see if you can follow the video…
Join us for An Evening With Elephants at EVE Encinitas on November 2nd, 5-7:30pm for a special in-person event to learn more!

When I was starting the project in 2005, learning to recognize individual elephants was tricky. Building the photo catalogue was laborious, we went through videos frame by frame trying to distinguish an ear flap here, a tiny hole there. But even then, there were a some who looked so unique that it was enough to see them once – they were difficult to forget. Continue reading →
The living elephants – Asian elephant, African forest elephant and African savannah elephant.
Guest post by Michael Pardo
Ask most people what sound an elephant makes and they are likely to think of a trumpet. In reality though, elephants produce an incredible variety of different vocalizations. The most common call is a deep, pulsating rumble, so low-pitched that human observers sometimes feel it more than hear it. Elephants also roar—powerful, bellowing sounds that carry across the landscape. And sometimes, they give combination calls, in which one or two rumbles and roars are stitched together with no pause for breath.
I visited Udawalawe in 2014 to work with the Udawalawe Elephant Research Project, and was especially fascinated by these combination calls. Combining meaningful units into sequences with an additional meaning is a key component of human language, but there are relatively few examples of this phenomenon in other species. Listening to the Udawalawe elephants, I was struck by the fact that they nearly always produced combination calls in the same order: a single roar followed by a single rumble. Why was this? Could it be analogous to grammatical rules in human language? Or could it be as simple as an anatomical constraint that made it difficult for the elephants to produce a rumble before a roar?

Electric fences that split forested habitat are all too common. As a result, occurrences like this are frequent.
Sri Lanka is part of the ancestral home of Asian elephants and a skeleton traced to this population now serves as the definitive “type” specimen. They existed before settlers colonized and cultivated, before the ancient tanks were built, before the kings and kingdoms, colonizers and governments. This was their land long before humankind set foot on it to set about defining visible and invisible boundaries for ourselves and everything else. Yet here we are, and we are here to stay, so our fates are now linked. An elephant is more than a mere animal or symbol. It is the most un-ignorable occupant of a swiftly vanishing world that harbors an infinitely old and precious natural heritage. It is also a force of nature that annually claims human lives. Therein lies the crux of the difficulty. There’s just one question we need to ask ourselves: do we want elephants (and their bretheren) to persist on this little island, or not? I pose this question on World Elephant day because we are at a juncture that will decide the outcome. Continue reading →
It was a perfectly framed shot of a young elephant breaking the electric fence, perhaps even looking a little gleefully smug about it. Still this was a relatively common incident, and while it was nice to catch at least one culprit in the act, the observation was hardly a breakthrough (pun intended). But as we watched on, it was what came next that was so beautifully, endearingly meaningful that we couldn’t help watching again, and again, and again. Continue reading →

India includes some of the largest populations of Asian elephants in the world: an estimated ~26 000 to 28 000 elephants distributed across four regions. Of the four regions, southern India includes the single largest population of Asian elephants in the world (~14 000) and elephants are distributed across the Western and Eastern Ghats.
I studied the ecology and behaviour of Asian elephants as part of an ongoing long-term project on elephants, the Kabini Elephant Project, which was started in March 2009 to study the social life of elephants. Continue reading →
We have the pleasure of watching elephants in broad daylight in precious few places like Udawalawe, where they are habituated enough to be placid and tolerant of onlookers. Indeed, one can get rather spoiled in this particular Park, because even the birds are unafraid and will happily sit and pose for your clumsy photograph from inches away. At times, certain exhibitionist pachyderms even appear to put on a show for the gawking crowds:
An elephant family rests under a tree in the hot midday heat. Situations like this were perfect for the playback experiments.
In October 2007 Lucy King and colleagues first made a splash by reporting that African elephants seemed to be rather put off by bees. I was still in Sri Lanka during my big “data collection year” as a graduate student, trying to figure out the social relationships among Asian elephants and recording vocalizations whenever I got a chance. Lucy’s first paper was a curiosity, but then three years later she followed it up with the even more intriguing finding that African elephants even produce alarm calls specific to bees. This got the attention of my advisor at Penn, Dorothy Cheney, who having expended considerable time thinking about such things as monkey alarm calls, dropped me a one-liner: “Have you seen this?” Continue reading →
