When the African bush falls quiet after sunset, pangolins begin their night. These solitary, scaled mammals are among the most strictly nocturnal creatures on the continent, and their entire biology is shaped around the demands of living in darkness. Understanding pangolin nocturnal behaviour reveals not only how these animals survive, but also why protecting them requires accounting for threats that peak after dark.
Nocturnality in pangolins is not simply a preference. It is a survival strategy refined over millions of years. By moving exclusively at night, pangolins avoid the peak activity periods of many large daytime predators such as lions and leopards, which, while also capable of hunting nocturnally, are often more active at dawn and dusk than in the dead of night.
Thermal regulation also plays a role. In the hot semi-arid savannas of southern Africa, including the Limpopo and Kalahari regions where Temminck's ground pangolin (Smutsia temminckii) is found, surface temperatures during the day can exceed 40 degrees Celsius. Pangolins lack the ability to sweat effectively and would overheat quickly if they moved at midday. Night temperatures drop considerably, making foraging far less energetically costly.
Field fact: Research from the Tikki Hywood Foundation in Zimbabwe and the African Pangolin Working Group in South Africa consistently shows Temminck's ground pangolins beginning movement within 30 to 60 minutes of full darkness, and returning to shelter before first light.
Pangolins have very poor eyesight. Their small eyes are adapted to detect movement and light levels rather than fine visual detail. In darkness this limitation matters very little, because pangolins hunt almost entirely by smell. Their elongated snout is densely packed with olfactory receptors, giving them the ability to detect the chemical signatures of ant and termite colonies through soil, bark, and leaf litter.
When a pangolin moves through the bush at night, it walks with its snout close to the ground, pausing repeatedly to sniff and press its nose into the earth. This behaviour, observed clearly in camera trap footage from reserves across South Africa's Limpopo province, allows the animal to follow underground scent gradients directly to the source of an insect colony.
Pangolins also appear sensitive to low-frequency vibrations. Termite mounds produce faint acoustic and vibrational signatures from the movement of millions of insects inside. While research on pangolin hearing is still limited compared to other mammals, field observations suggest that pangolins can detect active versus inactive mounds with remarkable accuracy, rarely wasting energy on abandoned termitaria.
A pangolin's night is largely structured around finding, opening, and consuming insect colonies. A single adult Temminck's pangolin requires between 140 and 200 grams of insects per night to meet its energy needs, which translates to visiting multiple ant nests or termite mounds across a wide area.
Tracking studies using GPS collars have documented the following patterns in southern African ground pangolins:
Distance covered: In a study published from the Tswalu Kalahari Reserve, individual pangolins were recorded travelling up to 10 kilometres in a single night during the dry winter months when surface termite activity is reduced.
Pangolins are not simply inactive during the day. They are carefully hidden. Ground-dwelling species use burrows extensively, and in much of southern Africa they rely on holes excavated by other animals. Aardvark burrows are particularly important, providing deep underground chambers where temperatures remain stable and predators cannot easily follow.
A pangolin sheltering in a burrow rolls tightly into a ball at the entrance or within the tunnel. The overlapping scales covering the outer surface of the curled animal present a nearly impenetrable barrier to anything trying to reach the soft underbelly. This ball posture, used both in burrows and when threatened in the open, is the pangolin's primary defence.
The African tree pangolin (Phataginus tricuspis), found in Central and West Africa and extending into East African forests, follows a similar nocturnal pattern but moves vertically through forest canopy rather than horizontally across savanna. Tree pangolins curl into a ball in hollow tree trunks or on broad branches during the day, then descend to the forest floor or climb through the canopy at night searching for arboreal ant species.
The nocturnal habits of pangolins create specific human-related threats. Poachers operate at night, using spotlights and dogs to locate pangolins during their active period. In South Africa, arrests related to pangolin trafficking frequently involve criminal networks working between midnight and 3:00 AM along rural roads bordering nature reserves.
Roads are also a hazard. Pangolins walking at night, particularly on warm tar roads that retain heat, are struck by vehicles. Rangers and wildlife monitors working in reserves like Dinokeng, Mokopane, and private conservancies in the Waterberg regularly patrol at night specifically because that is when pangolins are moving and when poachers are most likely to strike.
"You only ever really understand a pangolin when you follow one at night. They are completely different animals in the dark — purposeful, fast-moving, and utterly focused on the business of finding food." — African pangolin field researcher
Protecting nocturnal species requires nocturnal conservation strategies. For pangolins, this means:
Pangolin rehabilitation centres in South Africa, including those operated under the guidance of the African Pangolin Working Group, keep rescued animals in dark, quiet shelters during the day and allow movement and feeding at night to preserve their natural rhythm. Disrupting this cycle causes stress and can impair a pangolin's ability to survive release back into the wild.
The pangolin's nocturnal lifestyle is not incidental. It is the product of deep evolutionary pressure and a finely tuned set of sensory and behavioural adaptations. Every aspect of night behaviour — from the timing of emergence to the method of finding food, the distance travelled, and the selection of a day shelter — reflects a successful strategy for a species that has persisted for over 80 million years. Conserving pangolins means understanding and protecting the night-time world they depend on.
Most pangolin species are predominantly nocturnal, active between dusk and dawn. The Temminck's ground pangolin of southern and eastern Africa is the most strictly nocturnal, rarely moving during daylight hours. Some tree pangolin species have been observed with occasional daytime activity, but this is uncommon and usually stress-related.
Pangolins rely almost entirely on their highly developed sense of smell to locate ant and termite colonies in complete darkness. Their long, sensitive snout can detect insect activity underground and within rotting wood. They follow scent trails along the ground, pausing frequently to test the air before digging into a mound or log.
Ground-dwelling pangolins like Temminck's pangolin typically shelter in burrows during the day, often borrowing holes dug by aardvarks or porcupines. Tree pangolins curl up in hollow tree trunks or dense vegetation. In South Africa's bushveld, pangolins have been tracked returning to the same burrow system repeatedly over several weeks.
Telemetry studies tracking Temminck's ground pangolins in southern Africa show individuals covering between 2 and 10 kilometres in a single night, depending on insect availability and season. During dry-season months when termite activity is lower near the surface, pangolins may travel greater distances to meet their food requirements.
