Out on the lagoon at night, the team comes across a lone male elephant walking on the shore. Using a camera that records heat, not light, it is easy to pick out the animal in the darkness, and the elephant can be observed from the safety of the boat. Male bull elephants generally live alone, until they come into musth when they begin to look for a female to mate with. Females are only receptive for 3 to 6 days every 4 years, so finding a female in the jungle in time is a frustrating challenge for these lone bulls. Little is known about the forest elephants of the Congo basin. They live deep in the jungle and are most active at night. Using thermal imaging to study these animals gives lots of potential to learn more: markings invisible to the naked eye can be clearly seen in the images and could help identify individuals. It's even possible to see how an elephant's ears are used to regulate their body temperature, as their veins show clearly.
