Bush babies live throughout sub-Saharan Africa, from Senegal in the west to Somalia in the east, and from southern Sudan in the north down to South Africa. These small, nocturnal primates occupy a surprisingly wide range of habitats, from dense tropical rainforests to dry savanna woodlands, and scientists are still discovering new species in previously unstudied corners of the continent.
Geographic Range Across Africa
The bush baby family (known scientifically as Galagidae) spans nearly the entire width and length of sub-Saharan Africa. The most widespread species, the Senegal lesser galago, ranges from Senegal all the way to southern Sudan. Other species push the range eastward into Somalia and southward to the tip of South Africa, where the thick-tailed greater galago is found.
Central and western Africa are home to some of the oldest lineages. The family likely originated in central-western Africa during a period when equatorial rainforests were far more widespread than they are today. Two groups of dwarf bush babies still inhabit these forests, and some genera are found nowhere else. East Africa, meanwhile, has turned out to be a hotspot of diversity. At least six distinct species of dwarf bush baby have been identified in the Eastern Arc Mountains and coastal forests of Kenya, Tanzania, and Mozambique alone. One species lives only on the island of Zanzibar. Another is restricted to a few isolated patches of coastal forest in Tanzania.
New species are still being found. In Angola, researchers discovered the Angolan dwarf galago in Kumbira Forest in the country’s northwest. It was only the fifth new primate described from the African mainland since 2000. The team first noticed its distinctive “crescendo” call, which sounded like it belonged to a tiny bush baby, but the animal itself was remarkably large for its genus. Angola had seen very little primate research before this discovery, suggesting more species may be waiting in understudied regions.
Habitats: From Rainforest to Dry Savanna
Bush babies are not picky about their habitat type, though individual species tend to specialize. The lesser bush baby is particularly well adapted to drier environments, thriving in the savanna woodlands that stretch south of the Sahara. These open, tree-dotted landscapes might not seem like obvious primate territory, but bush babies do well there as long as there are enough trees for sleeping, foraging, and moving through the canopy.
Other species prefer wetter environments. Dwarf bush babies in central and western Africa live in tropical and subtropical rainforests, where dense canopy cover provides shelter and a steady supply of insects. The newly discovered Angolan dwarf galago occupies moist, tall forests (both primary and secondary growth) but also turns up in semiarid baobab savanna woodland, showing the flexibility some species have across habitat types. Scrub forests sit somewhere in the middle, and several species use these transitional zones where woodland gives way to denser growth.
Altitude matters too. Most bush babies are lowland animals, but the mountain dwarf galago lives in relatively cool montane forests in the Eastern Arc Mountains of Kenya and Tanzania. A potential subspecies documented in Kenya’s Taita Hills was found at elevations between 4,593 and 6,400 feet, making it one of the highest-dwelling bush baby populations on record.
Where They Sleep During the Day
Because bush babies are strictly nocturnal, where they spend the daytime hours is just as important as where they forage at night. Small family groups of two to seven individuals typically huddle together inside tree hollows during the day, sharing body heat and staying hidden from predators. When night falls, the group splits up, with each individual heading out alone to hunt insects or collect tree gum before regrouping at dawn.
This pattern means bush babies need forests or woodlands with mature trees large enough to have natural cavities. Areas that have been heavily logged or cleared of older trees lose the sleeping sites bush babies depend on, even if food is still available nearby.
Why Certain Trees Determine Where They Live
For some species, the presence of specific trees dictates exactly where they can survive. In Kenyan savanna woodland, researchers found that lesser bush babies ate exclusively insects and the gums of two Acacia tree species. The gum from one species was clearly preferred over the other. Population densities in the study area hovered around 1.5 animals per hectare across slightly different habitats, all of which had Acacia trees present.
Tree gum is a critical food source during dry seasons when insects become scarce. Bush babies have specialized teeth that let them gouge into bark to stimulate gum flow, then scrape it off to eat. This means their distribution often tracks closely with the distribution of gum-producing trees. Where Acacia woodlands thin out or disappear, bush baby populations tend to drop off as well.
Conservation and Population Trends
The two most widespread species are currently classified as least concern on the IUCN Red List. The thick-tailed greater galago has a stable population, while the lesser bush baby’s population is decreasing despite its broad range. Habitat loss from deforestation, agricultural expansion, and logging is the primary pressure across most of their range.
The species with the smallest ranges face the greatest risk. Bush babies restricted to a single mountain range, a few coastal forest fragments, or one island are vulnerable to even modest habitat changes. The Rondo dwarf galago, for instance, survives in just a handful of isolated forest patches along the Tanzanian coast. For species like these, the loss of a single forest could mean the loss of a significant portion of the entire population.
