Pangolins are among the most difficult mammals to study in the wild. They are nocturnal, secretive, solitary, and spend significant time underground. This means that detecting seasonal changes in their behaviour requires sustained, multi-year research programmes using GPS telemetry, camera traps, and indirect evidence such as digging activity and burrow occupancy. Only in the past two decades have enough long-term pangolin studies been published to reveal clear seasonal patterns across multiple species and habitats.
The primary driver of pangolin seasonal behaviour is prey availability. Pangolins are dietary specialists, consuming almost exclusively ants and termites (myrmecophages). Both prey groups have strongly seasonal activity cycles governed by rainfall and temperature. When prey is abundant and accessible near the soil surface, pangolins forage widely and gain condition rapidly. When prey retreats deeper underground during dry or cold periods, pangolins must work harder for lower returns, and their behaviour shifts accordingly.
The best-studied African pangolin for seasonal behaviour is Temminck's ground pangolin (Smutsia temminckii), primarily through long-term research programmes at Tswalu Kalahari Reserve and Phinda Private Game Reserve in South Africa, and at sites in Botswana and Zimbabwe.
In the southern African savanna context, the wet season runs roughly from November to March. GPS-tracked Temminck's pangolins show a consistent pattern of expanded home range during this period. Animals that maintain a dry-season home range of 15 to 20 km² may expand their nightly foraging circuit by 30 to 50 percent during peak wet-season months. The explanation is straightforward: termite colonies are actively repairing and expanding their mounds after summer rains, and large numbers of forager termites are working near the soil surface. A pangolin moving through this landscape can fill its stomach in fewer hours of foraging.
Body condition scoring of GPS-collared animals in South Africa consistently shows peak condition (maximum body mass relative to frame size) in late summer — February and March — when the wet season prey bonanza has translated into subcutaneous fat deposition. This fat, stored particularly in the tail base and haunches, is the animal's primary buffer through the dry season ahead.
As the dry season deepens from May to September in southern Africa, Temminck's ground pangolins shift their behaviour markedly. Foraging trips shorten, as animals must travel further and dig deeper to access termites that have retreated below the hardened surface soil. Some individuals shift their activity budget, spending more time investigating and excavating termite mounds rather than pursuing surface-active ant columns.
Den site selection changes seasonally as well. During the wet season, Temminck's ground pangolins use a variety of shallow scrapes and borrowed burrows, sometimes moving to a new den site every few days. In the dry season, animals tend to select deeper, more thermally stable burrows — frequently repurposing structures excavated by aardvarks, which provide shaft depths of one to two metres and maintain more consistent temperature and humidity than shallow scrapes. GPS data shows longer consecutive occupancy periods in single burrows during dry months, with some animals remaining in the same burrow for five to ten days rather than moving nightly as they do in the wet season.
Emergence timing also shifts. Dry-season pangolins emerge later in the evening (when ambient temperatures are slightly cooler and humidity slightly higher) and return to the den earlier in the pre-dawn hours, reducing their total above-ground exposure time. This reflects both the reduced foraging opportunity and the physiological cost of maintaining body temperature in very dry, hot conditions.
For arboreal forest pangolins — the white-bellied, black-bellied, and long-tailed pangolins of West and Central Africa — the seasonal signal is more muted because equatorial rainforests have less pronounced dry seasons than savannas. However, even in the Congo Basin, there are distinct wet and dry periods (typically June to August is a pronounced dry season in parts of the Republic of Congo and DRC), and ant and termite availability does shift accordingly.
Camera trap studies in the Nouabale-Ndoki landscape suggest that white-bellied pangolin detection rates increase during the dry season, possibly because reduced ground cover makes animals more visible to camera traps at forest floor level — or because animals descend from the canopy more frequently when arboreal ant activity drops during the dry months and ground-level prey becomes relatively more productive. This interpretation is consistent with the known semi-terrestrial foraging behaviour of white-bellied pangolins.
For the long-tailed pangolin, which is closely associated with riverine and swamp forest habitats, seasonal flooding cycles are more relevant than rainfall seasonality per se. During peak flood periods, animals are restricted to elevated tree zones and may show increased arboreal foraging pressure. As waters recede, they can exploit newly exposed ant trails along flood debris and recently inundated leaf litter, which hosts high ant and termite densities during the post-flood period.
India's pangolin species — the Indian pangolin (Manis crassicaudata) in the subcontinent's drylands and the Chinese pangolin (Manis pentadactyla) in South and Southeast Asia — show clear monsoon-driven seasonality. The Indian monsoon (June to September) triggers a peak in ant and termite forager activity that closely mirrors the wet-season prey bonanza of African savannas. GPS studies of Indian pangolins in Maharashtra and Madhya Pradesh show expanded home ranges and increased foraging distance during and immediately after monsoon months, with body condition peaking in October to November as animals build fat reserves before the winter dry period.
The Chinese pangolin occupies the highest-latitude range of any pangolin species, extending into montane Yunnan, Sichuan, and Taiwan at elevations where winter temperatures can drop near freezing. These animals enter a state of reduced activity from November to February in which foraging trips become infrequent and brief. Body temperature drops slightly but does not fall as dramatically as in true hibernators like bears. Animals remain responsive and may forage opportunistically on warm winter days. This cold-season semi-torpor is driven by the near-total cessation of above-ground ant and termite activity in cold conditions rather than by a genetically programmed hibernation rhythm.
The Sunda pangolin (Manis javanica) in Sumatra, Java, Borneo and mainland Southeast Asia occupies tropical rainforest with relatively constant temperatures but variable rainfall. Seasonal behaviour here is less well documented, but studies in Malaysia's Taman Negara and in Sumatra suggest that Sunda pangolins shift foraging vertically — spending more time in canopy foraging during the drier months when ground-level ant trails are less active, and shifting to ground-level foraging during the wet season.
Pangolin reproduction shows seasonal patterns in several species, likely driven by the timing of the wet-season prey peak. In Temminck's ground pangolin, births are thought to cluster toward the end of the wet season (February to April in southern Africa), meaning that females are in the final stages of gestation during the peak prey period and pups are born into a season of maximum food availability. This is adaptive because lactating females have higher nutritional demands and benefit from the wet-season foraging bonanza.
In Indian and Chinese pangolins, births have been documented across multiple months in captive animals, but wild population data suggests a wet-season birth peak consistent with the monsoon prey cycle. Female pangolins that give birth to heavier, better-conditioned pups — achievable when the mother has access to peak-season prey — are more likely to successfully raise offspring to independence. The seasonal alignment of birth timing with prey availability is therefore a critical fitness variable.
Climate change is altering the seasonal cues that pangolins depend on. In South Africa, rainfall seasonality in the Kalahari and KwaZulu-Natal is becoming more variable, with both more intense wet seasons and prolonged dry spells occurring within the same year. If the predictable wet-season prey peak that drives fat accumulation becomes less reliable, pangolins may arrive at dry-season conditions with inadequate fat reserves, increasing mortality risk.
For Asian species at the northern edge of their range, warmer winters in Yunnan and Taiwan could theoretically extend the foraging season and improve annual body condition — but only if ant and termite populations respond similarly. If ant phenology does not track the earlier spring warming, pangolins emerging from semi-torpor will find prey still inactive, creating a phenological mismatch similar to that documented in temperate bird populations.
These climate interactions underscore why long-term behavioural monitoring of pangolins — tracking seasonal activity patterns year after year at the same sites — is not just academically interesting but operationally necessary for conservation planning. Protected area managers who understand the seasonal movement and den-use patterns of their pangolin populations can schedule road closures, tourist management protocols, and anti-poaching patrol routes to minimise human disturbance during the most biologically critical periods of the year.
