Eyes Wide Open - Bushbabies or Galagos

Eyes Wide Open - Bushbabies or Galagos

Galagos are arboreal, nocturnal primates with long tails, long hindlegs and large forward-facing eyes. The wailing baby-like cries of the larger species have given the group the common name of bushbabies. Between 16 and 18 species occur in Africa, some being distinguished only on their call or, rather remarkably, the structure of their penis.

All galagos have incredible eyesight. Experiments have shown that they are able to see up to 30 metres using starlight alone, further when the moon is full. Bushbabies move nimbly through tangled branches and thorns in complete darkness. They have prodigious jumping abilities and can cover up to two metres in a single, elastic bound. Prior to leaping, the galago uses its large sensitive ears and acute eyesight to survey its surroundings. The arms are held forward and above the head, while the long tail serves as a rudder.

Diet

Like most other primates, bushbabies are omnivorous. Insects and other invertebrates make up the bulk of their diet, but they are especially fond of the sweet, sticky gum exuded by acacias. Members of the cat-sized Otelemur group frequently rob bird nests for eggs or small chicks, and may visit camp sites for pickings.

Home Range

Galagos live in family groups led by mature females. Territories are advertised by extensive scent-marking - a process whereby individuals urinate on their hands and feet to leave distinctive odour trails on favoured pathways. The often raucous vocalisations are another important way of advertising territory. Dominant males defend larger territories which may encompass several female groups. In ideal habitats, the density of Lesser Galagos may rise to 500 per square kilometre, somuch attention is paid to individuals spacing themselves out.

andBEYOND's Galago Hotspots

The Greater or Thick-tailed Galago is a common inhabitant of broad-leaved and riparian woodland and is frequently seen on night drives at Londolozi and Phinda. The diminutive Lesser Galago (sometimes called Nagapie) is abundant in acacia savanna at Londolozi, Ngala, Matetsi, Sandibe and Nxabega where guests are regularly treated to close views under infra-red beam. In East Africa, the Silver Galago is common within the Kichwa Tembo camp, and can also be seen at Grumeti and Klein's Camp.The Short-eared Galago occurs to the east of the Rift Valley and is regularly heard and seen at Lake Manyara Tree Camp.
