Habitats
Arboreal; forest canopy
Riverine, coastal, or dry/savannah woodlands
Prefer dense growth in forks of trees, not exposed branches
Females build leafy nests
Habituates well to humans and urbanized areas; may even scavenge lodges
and other human food sources
Live in small family groups, monogamous or polygynous
Territorial:
Female ranges may overlap
Male ranges do not usually overlap other males; may overlap several females

Diet
Omnivorous nocturnal foragers. Jump from tree to tree looking for:
Largely tree gums (acacia, etc.) and saps
Fruits: berries, figs
Seeds and flowers
Some insects: butterflies, moths, beetles, slugs
Some reptiles and small birds
Proportions vary with location
Infants: mother galago produces extremely rich milk

Diseases/Parasites Little information is available on diseases and parasites specific to O.
crassicadatus or to galagos in general
However, pet care websites warn that many primates, including galagos,
often carry zoonotic diseases and parasites such as Salmonella, Klebsiella,
and Campylobacter.
Wild galagos may also carry yellow fever.

Salmonella Klebsiella Campylobacter
Behavior Nocturnal, arboreal. 9.5 hours of activity per day in summer; 12 hours per day
in winter. Sleep in groups during day but separate at night to forage.
Groups of 2-7 animals (adult pair with young, adult females with young, lone adult female with young)
Urine washing: cover paws with urine to distribute scent widely when on the move
Don’t move by long jumps, just tree to tree (up to 2 meters). Typically run quadrupedally
Social interaction at gathering sites (range overlap, food sources, good sleeping trees)
Reciprocal licking of fur, posturing, visual cues
Vocalizing; different types of calls (clicking softly between mother and baby, louder clicking between adults, and loud cries, barks, and a high-pitched alarm call)
Males fight aggressively over possession of females
Reproduction, Life History, Life Span Mating may be monogamous or polygynous; depends on population density
Males breed with females whose territories overlap their own
Attract females by vocalization and scent marking
Litters of 2-3; young are altricial
Mothers leave their young in a nesting tree while they forage
Males become independent at sexual maturity; females may remain longer
Live 18 years or more in captivity; probably less in the wild

Reproduction
Female estrus cycle ~44 days
Mate Every 4-8 months*
Gestation ~124 days
Age at weaning ~61 days
Age at sexual maturity Sources vary; ~1-2 yrs
*Varies geographically and seasonally
Conservation Status
Galagos are important in controlling the insect populations in their habitats,
and serve as prey to larger animals
They may occasionally be hunted as food animals by humans, but not often
enough to be considered threatened
Greatest threat: loss of habitat through deforestation
However, the IUCN RedList classifies it a species of Least Concern:
“[T]he species is relatively widespread and common, present in a number of well-
managed protected areas, and there are no major threats.”
