a cavity like that
Green Wood-Hoopoe

nan, what do you think? Do we have an incubating female on her nest site here?
Yes Klipspringer I think you are right, because I observed this bird for a long time, without trying to approche to not disturb, it was so fascinating for me
nan, have you only seen one bird there?

Nan's photos clearly show how a photo can lie; in the second the trunk looks much bigger, but not the bird
it's from another angle.... the light brown trunk behind the second pic is the same like in the first but side by side
I know my English is deplorable

... but in one word : is the same trunk

The Common Scimitarbill
Rhinopomastus cyanomelas is a specialised feeder. Equipped with a long beak, powerful, gripping feet and long tail (used for balance and bracing itself), it is proficiently adapted for its arboreal lifestyle. There are few parts of a tree that it cannot access and its decurved bill allows it to probe deep under bark and into cavities and flowers. Its diet comprises primarily invertebrates such as termites, ants, wasps, flies, mantids, beetles and spiders, as well as their eggs, larvae (including caterpillars) and pupae.
They roost and breed in cavities and have the same stinky defence tactic as their woodhoopoe cousins. But they are not social, just breeding in pairs without helpers.

please! The Kalahari nerds should have some photos for us.

Bucorvidae
The Southern Ground-Hornbill Bucorvus leadbeateri is one of two species in the family Bucorvidae - the other being the Northern Ground-Hornbill B. abyissincus. The Bucorvidae are most notably separated from true hornbills (Bucerotidae) by not sealing the female into the nest cavity while breeding.
The Northern Ground-Hornbill inhabits drier steppe habitats north of the equator, while the Southern Ground-Hornbill occurs from the equator south, in savannah and grassland habitat, to the southern extremity of its range in the Eastern Cape Province of South Africa.
In South Africa, they occur most commonly in Limpopo, Mpumalanga, KwaZulu-Natal and the Eastern Cape Province. The highest recorded density is at Mana Pools, Zimbabwe (one group every 20 km2), while in South Africa, densities are much lower (one group per 100 km2).
They are the largest co-operatively breeding bird in the world, living in social groups of 2-12 members (mostly 3-5 members). Groups consist of an alpha breeding pair assisted by ≤5 adult males and ≤4 immature individuals of either sex. Non-breeding group members are generally retained offspring of the dominant pair. These individuals are subordinate helpers who contribute to group activities, including food provisioning to the
incubating alpha female and growing chick.
Southern Ground-Hornbills occupy year-round home ranges, which they actively defend. Territory defence is undertaken by adult group members and consists of regular pre-dawn vocalisations while still at the roost site and high aerial pursuits if groups hear or encounter rival neighbours. Their deep booming call, which is audible to humans at distances of up to 5 km, is most often a duet initiated by the alpha breeding pair, with the male calling at a lower pitch than the female.
