and hunt mostly on the ground. Their food ranges from insects to small animals. Their nests are often found in high tree cavities or other shallow cavities, such as rock holes in cliff faces. These birds are a long-lived species, having lifespans in the range of 50–60 years, and up to 70 in captivity. In relation to their long lives, they do not reach sexual maturity until 4–6 years old, and begin breeding around 10 years old. Their sex can be identified by the color of their throats: the male's is pure red and the female's is a deep violet-blue. Southern ground hornbills are a culturally pervasive and important species in southern Africa.

The calls allow each group to maintain its territory, which must be as large as even in the best habitat.


Breeding and life cycle

The southern ground hornbill is an obligate cooperative breeder, with each breeding pair always assisted by at least two other birds. Experiments in captivity have found that birds without six years experience as

are unable to breed successfully if they do become breeders. This suggests that unaided pairs cannot rear young and that the skill gained in helping as a juvenile is essential for rearing young as an adult. In captivity, a maximum lifespan of 70 years is recorded, and it is generally believed that the

ensures that only one nestling is ever fledged. The eggs measure by and are pure white in colour but very rough in texture. After a 40 to 45-day incubation period and an 85-day fledging period, the young remain dependent on their parents and helpers for between one and two years depending on climatic conditions, longer than any other bird. This means that ground hornbills can normally breed successfully only every third year. Triennial breeding is rare in birds: probably the only other example is the

, require conservation interventions to help increase their numbers. The bird's classification as endangered is heavily tied to its slow reproductive rates. Habitat loss, changes due to the agriculture, deforestation, electrocution from power lines, accidental poisoning, and persecution are the major factors that affect their populations. Persecution and hunting of the southern ground hornbill by human populations have continued to be complex issues. Recent studies have found the species has been hunted more than previously believed, including in protected areas. The majority of this hunting has likely been opportunistic. Overall, hunting is likely not a key driver for their lowering numbers. However, it is still a factor of which to be aware when considering conservation efforts, especially because of their low reproductive rates and an incomplete knowledge about local hunting habits in their natural regions. Furthermore, the southern ground hornbill faces persecution due to behaviors like destroying windows in response to seeing its reflection. Annoyed homeowners in urban areas in

have been known to kill birds that destroy property. The role of southern ground hornbills in a variety of cultural beliefs also influence conservation efforts. Some of these beliefs benefit their preservation. An example is the

, who believe killing southern ground hornbills is taboo due to their negative associations. However, the birds are also used in traditional cultural practices and medicines which can be harmful. In some marketplaces and cultures, southern ground hornbills are used in traditional medicines, which often rely upon harvesting specific parts of the bird. To date, research suggests that cultural uses do not have a significant impact on their populations. For example, the

. This bird species is especially threatened by the loss of trees and general habitat loss, as they require vast amounts of space for their territories. The removal of large trees for agriculture or wood harvesting, disturbances near nesting grounds, agricultural changes, all deeply affect the ability of southern ground hornbills to flourish. Due to the encroachment of human populations, it is not unheard of to see a group's territory encompass a variety of areas, from pristine habitats to commercial agricultural lands. Southern ground hornbills can have clutches ranging from one to three eggs, but only one of these are raised. With only one egg being raised, conservationists have taken it as an opportunity to raise the remaining eggs in captivity. Rehabilitation projects, such the Mabula Ground Hornbill Project, have been hand-rearing these extra chicks with the goal of reintroducing them to the wild, although reintroducing this species has proven challenging.


In culture

The southern ground hornbill's loud voice and large size have made it a focal point in many traditional African cultures. They have inspired a variety of cultural beliefs throughout many peoples that are within its broad historical range. However, the extent of these beliefs and whether they will persist into the future are uncertain, especially due to the modernization of Africa.

believe the southern ground hornbill can be used to bring rain and end droughts. This association has led the southern ground hornbill to be attributed with the ability to provide protection from weather-related problems. It is believed that if the proper traditional ritual is used, the bird can protect against lightning and drought. Rituals differ per culture and necessity for protection, as such a variety of parts may be needed from the bird, and may also involve dancing and singing.

Associations with altered perceptions

Possibly influenced by the southern ground hornbill ability to spot and hunt small creatures within tall grass, it has been associated with the ability to alter human perceptions. Though traditional rituals, the bird can be called on to improve or change a human's ability to alter reality, create illusions, and expand awareness. In

Furthermore, it's believed by some that the southern ground hornbill can be used to alter the perceptions of oneself. Thus, it has lent itself to be used in rituals to provide authority for leaders in certain cultures. Other cultural uses or beliefs include ridding one of bad or evil spirits, taking revenge on others or instigating fights, empowering a person, and causing dreams to become reality.
