Only regional figure available: South Africa subpopulation estimated at ~1,400 mature individuals (~50% historical decline there); Zambia noted as a relative stronghold with high group densities
- Habitat
- Savanna and woodland (including Mopane woodland and Acacia savanna), and grasslands adjoining forest patches; strongly associated with baobab and riverine trees for nesting/roosting cavities; occurs from sea level up to ~3,000 m elevation
- Fakta menarik
