The African olive pigeon is found mainly in South Africa, with a small population on the border between Mozambique and Zimbabwe. It lives mainly in indigenous forests, as well as suburban gardens and parks, where it can be found in fruit trees or bushes, its main source of food. The female builds the nest, with the male collecting the material, and putting it on the female's back, who then puts it underneath her body. It lays 1-2 eggs, which are incubated by both sexes, changing shifts in the early morning and late afternoon. The chicks are fed by both parents, and leave the nest after 19-20 days.

Distribution and habitat

Occurs from Ethiopia through Uganda, Kenya, Tanzania and Angola to southern Africa. Within southern Africa it is common in eastern and southern South Africa, Swaziland and Zimbabwe's eastern highlands and adjacent Mozambique. It generally prefers evergreen forests, riverine forests and thickets, alien tree plantations, urban gardens and parks, provided there are plentiful fruit trees and bushes.

Distribution of African olive-pigeon in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.  

Predators and parasites

Food 

Feeds almost exclusively on fruit, rarely feeding on fallen seeds on the ground. It usually forages in the canopy of fruiting trees, rarely going to the ground to feed on fallen seeds. The following food items have been recorded in its diet:

  • Fruits

    • Euclea crispa (Guarris)
    • Euclea natalensis (Guarris)
    • Ficus craterostoma (Forest fig)
    • Other Ficus species
    • Halleria lucida (Tree-fuchsia)
    • Ilex mitis (African holly)
    • Kiggelaria africana (Wild-peach)
    • Morella cordifolia (Dune waxberry)
    • Ocotea bullata (Stinkwood)
    • wild olive
      • Olea capensis
      • Olea faveolata
      • Olea verrucosa
      • Olea woodiana
    • Olinia cymosa (Hard-pear)
    • Olinia emerginata (Hard-pear)
    • Afrocarpus falcatus (Yellowwood)
    • Podocarpus latifolius (Yellowwood)
    • Podocarpus elongatus (Yellowwood)
    • Prunus africana (African almond)
    • Rapanea melanophoeos (Cape-beech)
    • Rhoicissus tomentosa (Common forest grape)
    • Scolopia mundii (Red-pear)
    • Sederoxylon inerme (White milkwood)
    • alien species
      • Ligustrum (pivets)
      • Prunus capuli (Mexican cherry)
      • Phytolacca dodecandra (Inkberry)
      • Phytolacca octandra (Inkberry)
      • Solanum mauritanum (Bugweed)
      • Duranta repens (Forget-me-not bush)
  • Seeds
    • Acacia cyclops (Rooikrans)
    • Acacia mearnsii (Black wattle)
    • Pinus pinea (Umbrella pine)
  • Carya pecan (Pecan nuts, eaten whole)
  • Recorded to eat mud at salt spring, reason unknown.

Breeding

  • It builds its own nest, the male collecting material then giving it to the female, who then adds it to the structure. The nest is a circular collection of twigs, with a depression in the middle, sometimes lined with leaves. Nests can be found in forks in trees such as African olive (Olea africana), White milkwood (Sideroxylon inerme) and sometimes pines (Pinus).
  • Egg-laying season is year-round.
  • It lays 1-2, usually one egg, which are incubated by both sexes for about 20 days, changing shifts in the early morning and late afternoon.
  • The chicks are fed by both parents, leaving the nest after 19-20 days.

Threats

Not threatened, but might be at risk due to destruction and fragmentation of forests.
