Wildlife photographer Will Burrard-Lucas prefers to take close, wide-angle shots of animals from the ground. Usually he'd quietly crawl up to them, but that would be too dangerous when shooting lions in the wild. So he started building a prototype for a mobile camera called "BeetleCam" because it resembles a large beetle as it moves and offers a beetle-like perspective. Photo: A lion biting a 'beetlecam'

With help from his brother Matt (right), Burrard-Lucas mounted a Canon EOS 400D on top of an off-the-shelf robot chassis. The "buggy" was stuffed with large batteries and rigged so that the camera connected to the steering controls. The first BeetleCam was sealed, camouflaged, and its center of gravity moved lower for better stability. Burrard-Lucas was ready to test it in Tanzania's Ruaha and Katavi National Parks.
On the morning of their first day out, the brothers took advantage of the warm light to capture elephants with the BeetleCam prototype. "We used it first on elephants and it worked really well," Burrard-Lucas said. The next day they decided to try it with lions.
What happened next was obvious in retrospect, Burrard-Lucas said. Curious about the mobile camera, a lioness picked it up and dragged it away. Fortunately the brothers were able to see where she dropped the mangled device. "Because there was no protection on it in those days, her teeth went straight through the camera and broke it," Burrard-Lucas said. They patched up the device, popped in another camera, and for the rest of the trip concentrated on elephants and buffalo instead.

Back in London, Will Burrard-Lucas set to work developing a new BeetleCam, this time custom-building much of it from scratch. "It took two years but eventually I found time to build what I hoped would be a lion-proof version," he said. This latest version (right), equipped with a Canon 550D camera, had better armor than the original. He also constructed a second, larger mobile camera (left) with a live video feed, HD movie recording, and a Canon 1Ds MK III digital camera that he dubbed "BeetleCam Mark II."
When the brothers returned to Africa in 2011, they traveled to the Masai Mara National Reserve in Kenya. This time the new BeetleCam had a carapace built out of fiberglass that was reinforced with aluminum struts. "I hoped it would be lion-proof and it did prove to be able to withstand the odd bite here and there," Burrard-Lucas said.

The brothers drove around the Masai Mara looking for lions. When they found some they deployed the BeetleCams. Lowering them out the vehicle's far window, away from where the lions were, usually worked quite well, Burrard-Lucas said. They frequently used the smaller armored camera to test the conditions. When the lion was distracted or not interested in the camera, then they risked rolling in the more expensive BeetleCam for higher quality photographs.
To control the BeetleCam remotely, Burrard-Lucas used a model airplane controller that has forward, back and steering capabilities. The airplane throttle was repurposed to tilt the camera lens up and down. A switch usually intended to raise and lower landing gear became the camera trigger. "I used the different channels to control different parts of the BeetleCam," he said.

The adult lions were predictably unpredictable, choosing to ignore the BeetleCam completely and then all of a sudden they would get up and bite it. Lion cubs, on the other hand, were usually playful and curious with the camera, Burrard-Lucas said. "They could tell which side the front was, and would try to get round behind to flip it over."
Although he uses the video camera, Burrard-Lucas said he considers himself more of a photographer than a videographer. "It's the art form and it's just what I enjoy doing," he said. "This approach allows me to get my images in front of a lot of people." In this photo, he used BeetleCam to capture a close-up of a male lion eating a wildebeest.
Burrard-Lucas continues to look for unique perspectives. The way wildlife photography is going, professionals need to come up with innovative ideas in order to take photos that haven't been seen before, he said. "In wildlife photography, once a few thousand photos of lions have been taken, you have to really try quite hard to get something fresh."

Using the dual BeetleCam approach has improved Burrard-Lucas' ability to compose shots instead of just crossing his fingers. Especially now that he's figured out how to transmit live, HD video from the BeetleCam's GoPro camera. "I can improve my success rate and make sure I can get the composition better rather than using a hit and miss approach," he said.
The wildlife photographer said he tends to think of a project or an animal he'd like to photograph and then goes about trying to build the tools that will enable him to get those shots. Next, we could be seeing a flying BeetleCam. "I might be doing something along the lines of a mini-helicopter version for aerial shots," he said.
Currently Burrard-Lucas is busy building BeetleCams for other wildlife photographers. He says a couple of them are planning to use the mobile camera to approach bears. "I'm giving them the same armor that lions had," he said. "We'll see if lions or bears turn out to be more destructive."

Most nature documentaries depict male African lions as layabouts who prefer to let the females do all the hunting. But a new study using pioneering new tools shows that the king of beasts could be doing his share after all.
The bad rap of male lions comes from a lack of data on what the males are really up to in the habitats where most African lions live -- not on the open plains of the Serengeti, but in the bushier lands of Africa.
By combining GPS collars that track lions' movements with airborne Light Detection and Ranging (LiDAR) measurements that provide 3-D map of the landscape and vegetation, a team of researchers has discovered the male lions' secret: They are solitary predators who leap out of thick vegetation to ambush their prey. That's in contrast to the well known social hunting behaviors of lionesses.
"We found a really strong correlation," said Scott Loarie of the Carnegie Institution for Science in Stanford, Calif., and the lead author of the paper on the lion discovery in the latest issue of the journal Animal Behavior.
The thicker vegetation, as measured by LiDAR, is where the males are making their kills. What's more, it's also the most difficult place to directly observe lions using traditional, low-tech methods of field researchers. So it's no wonder field biologists have had a hard time seeing this hunting behavior.
"For a very long time people have been putting radio collars on animals," commented conservation biologist Stuart Pimm of Duke University. "What is becoming exciting is that now we can now tie that information into a lot of other information" like the vegetation, as was done in this study. "You get information you couldn't get any other way."
When the GPS data indicated the lions were close together, it sometimes meant they were feeding on a recent kill. Another co-author on the paper, Craig Tambling of the University of Pretoria in South Africa, would then hike out and verified the kill on the ground.
Then back in California, Loarie and another coauthor, Gregory Asner, studied the data how the kill related to where the lions were beforehand. What they discovered is that the male lions are using thick vegetation to ambush their prey.
"The technology enabled us to get good quantitative data," said Loarie.
The backdrop to the work, said Loarie, is not just the technology and the insights about lions, but also the fact that vegetation thickness is one of the things that is intensely managed in African wildlife preserves.
"One of the things that's kind of neat is that we have implications for management and conservation," Loarie said. That's important because across Africa wildlife preserves are being managed to enable tourists to see certain animals, like lions, elephants, rhinos and leopards, he said. So it's important to understand what the animal's habitat really is. If you have an animal in the wrong habitat, that is more like a zoo than a wildlife preserve.
